Stainless steel balls have the characteristics of uniform particles, moderate hardness, high strength, and good toughness, which are safe, reliable, and have good technical effects, enabling processed products to highlight the metallic essence. Therefore, it has an increasingly widespread application trend in the industrial field. Firstly, one of the main application industries of stainless steel shot is the casting industry. We should know that usually the castings produced by casting enterprises need to be polished, and shot blasting cleaning machinery is a professional machinery used in this field. He uses different models based on different workpieces, and will not damage the original appearance and performance of the cast parts. In the mold industry, stainless steel shot products are often used. In fact, many molds are currently produced by casting, and the molds themselves require smoothness. Shot blasting cleaning machines can polish according to different requirements without damaging the original appearance and performance of the molds. So at this point, the shot blasting cleaning machine came in handy. When producing steel and steel plates in steel mills, stainless steel pellets are often used for treatment to improve the quality and sales of the steel. In addition, it has also been applied in shipyards. For example, the steel plates used in shipyards have rust, which can affect the quality of shipbuilding. It is impossible to use manual rust removal, which would require a large workload. This requires machines to remove rust to ensure the quality of shipbuilding. The use of a series of methods can be resolved. In automobile manufacturing plants, according to production requirements, many steel plates and castings require polishing treatment, while also ensuring the strength and original appearance of the steel plates. The appearance of the castings must be clean and beautiful. Therefore, stainless steel

Gear surface shot peening technology increases service life by 30% and greatly reduces noise
2023 / 07 / 05
Cast Steel Shot, Magnetic Polishing Needles, Stainless Steel Shot Shot peening is a shot peening technique that is different from shot peening. The purpose of shot blasting is to remove oil, scale, rust and machining burrs on the surface of the workpiece. The shot peening of the gear surface mainly relies on the impact of high-speed projectiles on the surface of the part, causing it to undergo elastic-plastic deformation, thereby producing favorable changes such as residual compressive stress, work hardening and microstructure refinement, so as to improve the bending fatigue strength of the gear. And contact fatigue strength, it is to improve the anti-occlusion ability of the gear, reduce the noise of the gear and improve the service life of the gear by more than 30%. 1. Mechanism and function of shot peening 1. Shot peening treatment can improve the stress distribution on the surface of parts The residual stress after shot peening comes from the inhomogeneous plastic deformation of the surface layer and the phase transformation of the metal structure, among which the inhomogeneous plastic deformation is the main one. After shot peening, plastic deformation in the form of a large number of pits occurs on the metal surface, the surface dislocation density greatly increases, and subgrain boundaries and grain refinement also appear. As shown in Figure 1. Part of the retained austenite on the surface of the gear after shot peening will turn into martensite, and compressive stress will be generated due to volume expansion during phase transformation, so that the retained austenite field on the surface will change towards a larger compressive stress direction, so Improve the fatigue strength of the gear. Through shot peening, it can eliminate heat tr

Determinants of the quality of stainless steel shot
2023 / 06 / 13
Cast Steel Shot,Metal Abrasive, Stainless Steel Shot In general, the quality of stainless steel shot is largely determined by its material and shape: 1: We must first choose which type of stainless steel shot is most suitable for ourselves. Firstly, we need to consider our product's pursuit of surface color, and secondly, we need to consider our product's production process, which requires anodizing, electroplating, and painting? It is still the biggest factor to consider which material to use when directly shipping the finished product after shot blasting and sandblasting. If it comes to testing materials, it's best to entrust it to a professional (such as consulting us). After all, in the era of mixed fish and dragon, it's not easy to buy the material you really want. A strong magnet and a bottle of medicine are essential; 2: We distinguish quality by observing the shape of stainless steel balls. We place the stainless steel balls on the table and then observe whether the shape of the stainless steel balls is standard, whether it is diamond, cylindrical, or spherical. When the stainless steel shot is too fine, we can rub it with our hands (or observe it through a high-power mirror) to feel if it is smooth. If there are any scratches on our hands, it proves that the shape of the stainless steel shot is not very regular and the quality is not good. The sandblasting effect of stainless steel balls with a spherical shape will make the product feel more delicate, and the most crucial point is that stainless steel balls with a spherical shape will be more durable, which is beneficial for reducing production costs.

Advantages of stainless steel shot compared to shot blasting materials
2023 / 05 / 23
Cast Steel Shot, Metal Abrasive, Stainless Steel Shot From the current market situation, we can find that there are many different types of shot blasting materials, such as ordinary steel shot, aluminum oxide emery, glass bead and stainless steel shot. So, what is unique about stainless steel shot among these different types of shot blasting materials? Below, we will analyze this issue and hope to assist us. In fact, stainless steel shot has been widely used, mainly in the spraying and polishing treatment of the surface of copper, aluminum, zinc, stainless steel and other workpieces. After processing, these metals can exhibit their original metallic nature, giving them a very shiny and matte appearance. In addition, the workpiece obtained after using this spray polishing treatment no longer requires the process of acid cleaning and rust removal, which is both convenient and environmentally friendly. In addition, compared to other materials, stainless steel pellets also have outstanding wear resistance. According to statistics, the consumption of each ton of aluminum alloy castings during polishing treatment is still lacking in kilograms. This has obvious advantages compared to other data. For example, ordinary steel shot is only half of it, while glass bead is only one tenth of it. In addition, stainless steel balls also have a series of advantages, such as their composition being very uniform, the purity of particle size being high, the surface structure being fine, shiny, non rusting, moderate hardness, and long service life. Overall, this information can be regarded as the best choice of abrasive for descaling, deburring, and visually intact machining.

What are the characteristics of stainless steel balls Simply put, stainless steel shot is actually a material used for the production of metal workpieces. Of course, its performance is relatively good. Not only is the particle size relatively average, but the effect we use it to process is also relatively good. This naturally improves the endurance of the workpiece. When using stainless steel balls, we should also check if their uniformity meets the requirements and ensure that their hardness is relatively high. In this way, we should also pay attention to their elasticity, otherwise we cannot improve the efficiency of stainless steel balls, which is also something we should consider. 2. Wear resistance of stainless steel shot If you are a friend who uses stainless steel balls, you should know that for stainless steel balls, their wear resistance is still a concern for us. Of course, we should also ensure that he has a certain degree of impact resistance to leave, so that he can use it for a relatively long time. Of course, we should also do a good job in protecting him, so that he can use more places. During the process of using stainless steel balls, we should also know their performance, and we should not allow them to rust. Of

Measures to Solve the Problem of Sandblasting of Zinc Alloy Die Casting Products
2022 / 08 / 15
Cast Steel Shot, Metal Abrasive, Stainless Steel Shot With the rapid development of society, the application of zinc alloy die-casting products is more and more extensive. Many zinc alloy die-casting factories often encounter the phenomenon of sandblasting and peeling. Longlived has been producing sandblasting for many years. Combined with the die-casting experience that sandblasting is required for connector die-casting, the measures to solve the sandblasting problem of zinc alloy die-casting products are summarized. 1. Before die casting, inspection should be strengthened, and parts with serious defects such as water marks, pores, and pinholes on the surface of the product should be reduced to ensure the compactness of die castings. 2. Every time the mold completes a batch of orders, it needs to save the mold cleaning and maintenance. 3. If it is true that the die-casting product has cold streaks, sweep the surface with soft nylon to reduce the peeling phenomenon. 4. The choice of sandblasting sand is very important. If the material of the embryo is not too hard, the selection of brown corundum can reduce the peeling. This also tells our friends, not only to learn and accumulate knowledge of various die-casting techniques in daily life, but also to pay attention to the quality of sandblasting and brown corundum. Both aspects are strictly controlled, so that problems can be found in the process. Find solutions in orde
How to check whether the steel sand is qualified?
2022 / 08 / 05
Cast Steel Shot, Metal Abrasive, Stainless Steel Shot Steel grit is often used for the treatment of metal surfaces, and the products treated with steel grit can meet national standards. Steel grit is one of the commonly used abrasives and is made from selected raw material scrap steel. Steel grit is currently an ideal high-quality material for cleaning, blasting, rust removal and strengthening at home and abroad. High-quality steel grit products have moderate hardness, strong toughness, and impact resistance. They can be used repeatedly for several times. At the same time, they have long service life, good resilience, strong adhesion, fast cleaning speed, low sand consumption, no breakage, and high brightness for cleaning workpieces. Technical effect Good and many other features. This is also the advantage of high-quality steel grit. The treatment effect of inferior steel grit is greatly reduced, so how to check whether the steel grit is qualified? 1. Hardness. The steel grit is too soft, which will slow down the cleaning speed and reduce work efficiency. During sandblasting, too soft steel grit cannot generate suitable residual stress, and the force of low-hardness sand cannot be compensated by increasing the impact time. If the hardness is too high, it will produce an unsatisfactory surface morphology, increase the probability of sand breaking, make the consumption too high, and wear more equipment and increase equipment maintenance costs, so proper hardness is also critical. Second, the microstructure. The microstructure of steel grit must be able to resist deformation and reduce energy l
Do you know where steel shot is used?
2022 / 07 / 30
Cast Steel Shot, Metal Abrasive, Stainless Steel Shot In recent years, the demand for steel shot has been increasing, and many people do not know the fields where steel shot can be used. Today, we will briefly talk about which fields steel shot can be used in. Steel structure construction enterprises: The steel structure needs to be derusted before use, which can meet the structural requirements stipulated by the state. The pass-through shot blasting machine adopts fully automatic cleaning, which does not require manual derusting, which saves labor costs and reduces pickling. Environmental Pollution. Shipyard: The steel plate of the shipyard has rust, which affects the quality of shipbuilding. Manual embroidery removal is used, which requires a lot of work and high labor costs. This uses machines to remove rust to ensure the quality of shipbuilding. Steel mill: The steel and steel plates produced by the steel mill have many burrs when they are just released, which affects the quality and appearance of the steel. These problems can be dealt with using a pass-through shot blasting machine. Automobile factory: According to the work requirements of the automobile factory, the steel plates and some castings used need to be polished, but the strength and original appearance of the steel plates cannot be damaged. The appearance of castings should be clean and beautiful. Due to the irregularity of auto parts, different polishing machines are required to complete it. Mold industry:
Analysis of the causes and treatment methods of blackening of castings after shot blasting
2022 / 07 / 21
Cast Steel Shot, Metal Abrasive, Stainless Steel Shot After the casting is produced, in order to achieve better use effect, the casting is generally shot blasted. Shot blasting is a cold treatment process, which is divided into shot blasting and shot blasting. Shot blasting, as the name suggests, is to remove impurities such as surface oxide scale to improve the appearance quality. Shot blasting is to use high-speed moving projectiles (60-110m/s) flow. Continuous impact strengthens the workpiece surface, forcing the target surface and surface layer (0.10-0.85mm) to undergo the following changes during cyclic deformation: 1. The microstructure is modified; 2. The non-uniform plastic deformation outer layer introduces residual compressive stress, and the inner surface produces residual tensile stress; 3. The outer surface roughness changes (Ra Rz). Effect: It can improve the fatigue fracture resistance of materials/parts, prevent fatigue failure, plastic deformation and brittle fracture, and improve fatigue life. But sometimes we will encounter the situation that the whole surface of the casting is blackened or there are obvious black marks and black spots in the part after shot blasting. On the surface, it can be removed, but it is difficult to handle if it has been immersed in the casting matrix. The reasons for this are: 1. Defects that existed before the shot peening brought by the die casting process:
Processing characteristics of shot peening
2022 / 07 / 13
Cast Steel Shot, Metal Abrasive, Stainless Steel Shot Shot peening are driven by a shot peening machine powered by compressed air, so that it can obtain strong kinetic energy and bombard the metal surface through a nozzle. When the bombardment intensity is greater than the yield stress of the metal surface, the metal surface undergoes a plastic change, and is bombarded into a concave shape by the steel shot, resulting in a compressive stress layer on the metal surface; the metal will be subjected to cyclic alternating loads during use, and the alternating load will form Tensile stress, resulting in metal fatigue fracture. After shot peening, compressive stress will be formed on the metal surface, which can effectively suppress and offset the tensile stress, delay the occurrence of metal fatigue, prolong the service life of the metal, and increase the wear resistance and corrosion resistance of the metal. This is the residual stress strengthening in shot peening; in the process of shot peening, the bombardment of the metal surface by the pellets will also strengthen the metal structure and reduce the structural fracture in the non-stress bearing direction, which is the structure in shot peening. strengthen. Features of shot peening processing: The power source of shot peening is compressed air, so the structure of shot peening machine is simple and reliable. Pill handling is convenient and is not limited to the shape and location of the product. The shot peening machine has multiple nozzles with different stations, and the workpiece can be rotated and reversed on the fixed table, so that it is fully exposed to the flow of shot peening without dead ends; however, the ener

Method for improving the quality of steel shot after polishing
2022 / 06 / 23
We all know that the grinding of steel shot usually has three processes: rough grinding, medium grinding and fine grinding. Each transfer process requires the use of finer abrasives and an appropriate reduction in the rotational speed of the grinding wheel, resulting in a finer finish than the previous pass. Generally, the specific steel shot polishing step depends on the surface roughness of the workpiece itself. In addition to the serious scratch marks on the aluminum material, the machined parts can be polished with l60#, and then the steel shot can be polished. It is not suitable and does not advocate one-time grinding with fine sand abrasives, otherwise it will not only reduce the work efficiency, but also affect the service life of the polishing wheel. In order to improve the polishing quality of the steel shot, the rough machining track marks left by machining must be completely ground during rough grinding, and the marks left by rough grinding must be ground during medium grinding, so that the surface finish of the workpiece is gradually improved. Improve and improve, otherwise it will not only cost labor and materials, but also the quality cannot be guaranteed. In addition, in order to avoid the repetition of the steel shot polishing track and improve the steel shot polishing quality and polishing efficiency, the direction of the grinding wheel in each polishing needs to cross the previous grinding track. By polishing the steel shot, various macro defects such as burrs, rust, scratches, weld flashes, weld seams, blisters, and oxide skin can be removed on the surface, so as to improve the flatness and electroplat
Why does the hardness of Stainless Steel Wire Cut Shot affect its service life?
2022 / 06 / 14
We all know that wire cutting shot has a wide range of uses, such as cleaning, rust removal, strengthening, shot peening, shot blasting, sanding, pretreatment, etc. Steel wire cut shot is a shot cut from steel wire. According to the different use, it is divided into stainless steel wire cut shot, ordinary high carbon steel wire cut shot and low carbon steel wire cut shot. In order to prevent the excessive consumption of steel wire cutting pellets during use, many manufacturers have affected factors of service life in order to effectively prevent some problems. Here, we shares two influencing factors for you. First, the hardness of the steel wire cut shot determines the service life of the steel wire cut shot The blast hardness is proportional to the finishing speed. The higher the hardness, the faster the finishing speed. Conversely, sandblasting, the higher the cost, the shorter the life. The production process of blasting determines that the size of blasting is inconsistent. The larger the diameter, the higher the ability to trim a rough appearance, but the greater the abrasion to sandblasting Second, the quality of sandblasting in accordance with the density is stable Shot peening density is also an important factor in determining the service life of shot peening. As long as the shot peening that meets the density can show stable quality, its ability will decline, and it will break and wear during processing. After the above intr
