Stainless steel shots are widely used in surface treatment of non-ferrous metal die castings, castings, aluminum profiles, auto parts, machinery manufacturing, hardware, pump valve industry. Mainly focus on removing surface oxide scale, edge surface burr, surface roughening, matt suburban fruit, smoothing and strengthening, and rust removal treatment.

Stainless steel pellets are commonly known as stainless steel wire cutting pellets, which are refined by drawing, cutting, rounding and other processes. The appearance is bright and rust-free, and the shape of beads (cut pellets, cylindrical)

Stainless steel pellets have moderate hardness, pure ingredients, and large coverage. Since they have no shortcomings such as pores and special shapes of cast steel pellets, they have a longer service life. The performance of this product can completely replace imported products, and the price is significantly lower than imported. Products to save costs for customers. After treatment with stainless steel shots, the surface of the casting is smooth and does not rust, and no post-treatment such as pickling is required, which is beneficial to environmental protection. You can choose pre-polished round cut pellets and non-pre-polished pellets, two different shapes of products.

As an easy material for surface treatment, stainless steel pellets have a large demand in the industry in the past year. In the past few years, the suppliers of stainless steel pellets were mainly domestic agents of foreign stainless steel pellets. Falcon, etc. With the joining of domestic stainless steel pellet manufacturing enterprises, the price of stainless steel pellets is decreasing year by year, the scope of use is continuously expanding, and the amount of use is also increasing year by year.

Currently, domestic manufacturers of stainless steel pellets are mainly concentrated in Jiangsu and Zhejiang areas, and some enterprises in Hebei, Shandong, Shenzhen, Fujian and other places are preparing to produce stainless steel pellets. Most companies that want to produce stainless steel shots have previously produced abrasives, and are very familiar with the market situation of stainless steel shots. Some originally acted as agents for foreign companies. Because there were users in their hands, they turned to produce and sell their own stainless steel pellet products.

The production technology of stainless steel pellets is not complicated. The investment of the main pelletizing equipment can be made in hundreds of thousands, and the price of the equipment is not more expensive than an ordinary machine tool. However, as a new steel shot production process, manufacturers must be aware of risks when introducing this technology. If they are not prepared to take risks, it is best not to touch this project.

The domestic production of stainless steel pellets was first produced by Changzhou's cast steel pellets. The water spray method was used. The stainless steel pellets obtained were similar to the cast steel pellets. The surface was oxidized and blackened. The process was improved afterwards, but still There is a problem that the surface of the steel pellets yellows and there are many hollow pellets, especially hollow pellets, which have a great influence on the quality of the product. I hope that the less the better, the better.

After , some manufacturers used the turntable method to produce stainless steel pellets, and also achieved success, but the oxidation problem of steel pellets and the yield of steel pellets are not ideal. The oxidation of the stainless steel pellets is improved by introducing nitrogen gas during the formation of pellets.

Yield is a process problem related to factors such as the metal superheat during pelleting, the rotating speed of the turntable, the composition of the molten steel, the flow rate and other factors. By adjusting the process parameters, a better yield can be obtained.

Although it can be concluded from the sporadic data from abroad that the water atomization method is used to make stainless steel pellets abroad, the specific process is unknown, and the stainless steel pellets made by groping are not ideal. According to the experience of producing stainless steel metal powder, when you want to obtain spherical powder, the gas atomization method is the inevitable choice. Spherical stainless steel powder was produced by a special manufacturer in China more than ten years ago, but the spherical stainless steel powder produced was used as a raw material for making filter elements. For example, the tempering flame arrester used in oxygen-acetylene gas welding equipment, the core element is a stainless steel flame retardant tube sintered with spherical stainless steel powder, this element is equivalent to a tube of metal sponge material, and tempering occurs during welding When the flame passes through the wall of the flame arrestor, it will naturally extinguish, so as to achieve the purpose of preventing flashback, so as to ensure the safety of the welding operation. Because of the intersecting lines, despite the fact that some companies have produced spherical stainless steel powder called stainless steel pellets in the abrasive industry more than a decade ago. In the abrasives industry, no one knows this situation. Some people are constantly looking for what method can be used to produce stainless steel shots. Finally, it was found and confirmed that the gas atomization method is the way to industrially produce stainless steel pellets, and the leading companies have made a lot of profits.
