forged grinding balls

Raw materials: Forged Steel Ball, the raw material required for forging steel balls, is all ordered from large national steel plants, and special processing can be carried out according to the special requirements of different wear-resistant steel ball materials.

Raw material heating: we use energy-saving induction rod heating electric furnace for heating, which can ensure the uniform temperature of the whole raw material and greatly reduce the loss of raw materials. The uniform temperature of raw materials after heating can ensure the uniform hardness of wear-resistant steel balls during heat treatment.
