High Hardness Carbon Forged Steel Grinding Ball 60mm 150mm Forged Grinding Steel Balls
Forged steel balls are made by heating the metal to a suitable temperature, applying pressure to the metal blank by forging, causing it to undergo plastic deformation to obtain steel balls with certain mechanical properties, shapes and sizes. This process can eliminate defects such as loose casting produced during the smelting process, optimize the microstructure, and preserve the complete metal flow line, so that the mechanical properties of the forging are better than those of the castings of the same material.
Heating the customed steel until the temperature reaches 1100C( 土50C) in the way of hot rolling and forging,the rollig forging machinery will put pressure on the metal blank and producing a grinding ball with certain mechanical property, shape and size . This is our processing methods of the grinding balls.
