How about analyzing the industry of stainless steel beads today?
stainless steel bead ball as a material for surface treatment, the demand for industry in the past year is very large. With the addition of domestic stainless steel bead ball production enterprises, the price of stainless steel bead ball is declining year by year, the scope of use is constantly expanding, and the amount is more than one year. At present, domestic stainless steel bead ball production enterprises are mainly concentrated in Jiangsu and Zhejiang provinces, and enterprises in Hebei, Shandong, Shenzhen, Fujian and other places are also preparing to produce stainless steel bead balls. Most of the enterprises that want to produce stainless steel bead balls used to produce abrasives and have a good understanding of the market situation of stainless steel bead balls. Some of them were originally agents for foreign companies, because they had users in their hands, so they turned to produce and sell their own stainless steel bead products.
The production technology of stainless steel bead ball is not complicated, and the main pill making equipment can be invested in hundreds of thousands, the price of the equipment is no more expensive than an ordinary machine tool. However, as a new steel shot production process, manufacturers should have risk awareness when introducing the technology. If they are not prepared to take risks, it is recommended not to touch this project. The production of stainless steel beads in China has long been the manufacturer of cast steel balls in Changzhou. The water spray method is used. The obtained stainless steel beads are similar to the cast steel balls, and the surface is oxidized and blackened, however, there are still problems such as yellow surface of steel pellets and many hollow pellets, especially hollow pellets, which have a great impact on the quality of products. I hope the less the better, the suggestion is not.
after that, some manufacturers used the turntable method to produce stainless steel pellets, which also achieved success, but the oxidation problem of steel pellets and the yield rate of steel pellets were not ideal. The oxidation of stainless steel beads is improved by introducing nitrogen into the pellet. Yield is a process problem related to factors such as superheat of metal, rotating speed of turntable, composition of molten steel, flow rate, etc. By adjusting process parameters, a better yield can be obtained.
