What is the difference between grinding balls and cast steel balls?

　　In industrial production, grinding shots and cast steel shots are two common types of metal abrasives, which have many differences in material properties, manufacturing processes, application fields, and service life. The following will provide a detailed comparative analysis of grinding balls and cast steel balls from multiple dimensions:

　　1. Grinding shot: Grinding shot is a high-precision and high-strength grinding medium, usually made of high-quality alloy steel such as high manganese steel. The manufacturing process includes multiple steps such as melting, spray forming, and heat treatment. Firstly, the raw materials are melted, and then the molten steel is sprayed with high-pressure water to form tiny pellets. Then, the pellets are quenched and tempered to achieve the required hardness and toughness. Finally, they are sorted into products of different specifications through mechanical screening.

　　2. Cast steel shots: Cast steel shots are made from high-quality steel shavings. The manufacturing process generally involves first melting steel scrap, then spraying high-pressure water to form small shots of molten steel. The formed shots are then reheated to purify the homogeneity, followed by quenching treatment. The quenched shots are dried and reheated in the furnace to achieve the appropriate hardness, and then sorted into grades that meet the standards through mechanical screening.
