For the grinding steel cylpebs for copper ore mine, wear-resistant materials must be used for wear resistance, such as 60Mn, 65Mn, or high-efficiency wear-resistant alloy steel materials independently developed by some companies.
How to distinguish between steel segments and cast grinding steel cylpebs for copper ore mine
1. The steel ball produced by the casting smelting method is called the cast steel section, and does not need to be smelted and cast. However, the steel ball manufactured by forging is called the grinding steel cylpebs for copper ore mine.
2. Due to different materials and processing techniques, the hardened inside and outside of the heat treatment is poor, and the hardness of the inside and outside of the steel ball is greatly different. Because the forged steel section has a good combination of high carbon, manganese and chromium alloy elements, the heat treatment hardenability is strong. The difference between the inner and outer hardness is small, and because of the difference in impact value, it is determined that the forging section is more unbroken than the casting section.
3. The fracture rate of the forged steel section is small, and the fracture rate of the cast steel section is large. In general, the fracture rate of the cast steel section is 3%, while the forged steel section is at 1%. Due to the small fracture rate, the powder extraction rate of the mill is increased. And reduce the cost of mineral processing, which increases the efficiency of mill production. www.grindingballsmedia.com
