Ball bearing steel processing technology classification

Bearing steel ball according to the production and processing technology is divided into grinding steel ball, forging steel ball, casting steel ball; According to the processing material is divided into bearing steel ball, stainless steel ball, carbon steel ball, alloy ball. Among them, the alloy steel ball is a kind of spherical iron alloy wear-resistant body which is mainly formed by adding carbon, chromium, manganese and molybdenum and is formed by forging, spinning, rolling and casting, Mine ball, cement balls and other the most important part.

 

Factors affecting the quality of bearing steel ball

1. The chemical composition of the elements: the finished steel ball due to the contained chemical composition such as iron, carbon, chromium, manganese, sulfur, phosphorus and other ingredients, then the ball hardness, impact wear have varying degrees of impact, in general , A large amount of chromium, the ball wear resistance high. The company is located in:

2. Ball manufacturing methods affect: Rolled and forged steel ball of its dense structure, so the density of cast steel ball, cast iron ball or casting alloy ball and other organizations are not dense, and even there are pores, so the density Smaller. The company is located in:

3. Ball microstructure effects: martensite, austenite, bainite, ferrite and other different crystal structures are not the same density, but also affect the fineness of the crystal.
