steel ball
Summary
According to the processing technology, steel ball is divided into grinding ball, forging steel ball and casting steel ball. According to the processing material, it is divided into bearing steel ball, stainless steel ball, carbon steel ball, alloy ball and so on. The alloy steel ball is a kind of spheroidal ferroalloy wear-resistant body, which is mainly composed of carbon, chromium, manganese and molybdenum, and is formed by forging, spinning, rolling and casting. It is the most important part of grinding industrial mines, cement balls and so on.

Classification of steel ball
[1]
From the perspective of applied categories, steel balls can be divided into two categories, namely, the application of grinding industry wear-resistant steel balls and the application of precision bearing industry to bearing steel balls. Wear-resistant steel ball (abbreviated ball) is the most widely used product in industrial practice today. It is called "industry must be crushed". Bearing steel ball has a long history in the field of precision bearing industry and life. It should be called steel ball in narrow sense.
The steel ball is a general name for steel balls, steel sections and special-shaped abrasives. From the shape, it can be divided into a positive round ball (now a universal appellation), a capsule ball, an ellipsoidal ball, a yin and Yang ball, a hollow ball, a multifaceted ball, and a short ball (there is a pit on the surface).
There are four main types of steel ball production: forging, rolling, semi-solid forming and casting. Because of the special use conditions and the comprehensive environment and the background of the history and mineral processing industry, the forging and rolling balls occupy a considerable proportion in these industries. Semi solid molding has the characteristics of unconventional casting, which can be explained by non simple die-casting. It has attracted people's attention by the excellent performance of a kind of advanced technology such as casting, forging, forging and forging. The cast steel ball, with its simple, flexible and reliable way of production, is easy to achieve the expansion advantage of low investment and large-scale production, especially when experts and engineers face the design of various advanced processes and alloy components in the steelmaking furnace, play endless imagination to create a more novel and more advanced variety, To meet the competitive needs of the sense of achievement, more people can understand. Of course, the high performance price ratio and the potential of continuous development make it the main force in the crushing industry, especially in the production mode of the cement pulverizing industrial steel ball.
