The steel ball of bearing steel is divided into a certain extent from the appearance. To a certain extent, it can be effectively divided into round balls, capsule balls, oval balls, yin and yang balls, hollow balls, multi-faceted balls, and many missing balls (surfaces have Pit) and so on. Ball production methods generally include forging, rolling, semi-solid forming and casting.
The semi-solid forming of the bearing steel ball has a very conventional casting to a certain extent. When it is used, it is a kind of advanced technology that combines the advantages of casting and forging and casting and forging. attention. The cast steel ball is easy to realize the expansion advantages of low-cost large-scale production with its simple, flexible and reliable production methods.
Bearing steel balls are effectively used to a certain extent in the design of various advanced technologies and alloy compositions, to a certain extent to exert their endless imagination, so that one can create a newer and more advanced varieties. The sense of accomplishment brought about by meeting the needs of competition is more than anyone can appreciate. The cost-effective and sustainable development potential of cast ball, of course, makes it the main force in today's crushing industry, especially in the production of cement crushing steel balls.
Bearing steel ball impact requirements
1. Influence of material density: Steel ball, cast iron ball, alloy steel ball, etc. The density of different materials is different. The density of steel is larger than that of cast iron. The alloy steel is different according to the density and content of the main alloying elements.
2. Influence of manufacturing method of steel ball: The steel balls rolled and forged have a dense structure, so they have a high density and cast steel balls.
3. The influence of the chemical composition of the bearing steel ball: In the course of the operation, the finished steel ball is mainly produced due to different chemical components such as iron, carbon, chromium, manganese, sulfur and phosphorus. The impact on the hardness and impact wear of the steel ball is different. In general, when the chromium content is large, the steel ball has high wear resistance. Finally, a good reminder that the good lubrication of the ball mill directly affects the service life of the ball mill bearings. The requirements for the lubricant oil injected into the ball mill must be clean and the seal must be good.
