Manufacture by means of hot rolling ensures product structure accuracy and absence of defects; Grinding media manufactured by means of hot rolling have perfect geometric form with no metallurgical defects to reduce expenditure norms while ball mill charging.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates. Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision. Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.

For grinding balls, the last two ways are the best. Moreover, for super high chrome balls, air quenching is welcomed than oil quenching. But, like 10-18%Cr, oil quenching is the most popular. Quenching process: first heating the grinding balls up to the certain degrees in particular time, then quench directly to oil or air for several minutes.

To manufacturer grinding balls for good quality, the heat treatment process is vital. It influences the ball's HRC, impact value, and internal microstructures. There are two necessary steps for casting chrome balls: quenching and tempering. Quenching, including air & oil quench, is to increase balls' HRC.
