forged grinding steel ball

forged grinding steel ball

the forged grinding steel ball is made by direct heating at high temperature and forging and it do not need melting and casting. so this steel ball is called forged steel ball.

details

advantages

1. the defects produced in smelting process will be eliminate by forging which optimizes the microstructure and preserve the integrity of metal flow. forging mechanical performance is better than that of the same material casting.

2. the wear-resistance of forged steel ball completely depends on the material. wear-resistant steel ball adopts excellent quality steel which has the advantages of good impact resistance strong toughness and good wear resistance etc.

appliion

iron ore copper gold cu-pb-zn and other wet grinding field.

production process flow of forging steel ball

inspection of raw materials--heating and melting of intermediate frequency furnace---spin into ball --- quenching----tempering----testing---package

the ball with diameter 100mm is used in impact fatigue test the test height is 7.5m the impact times of the ball with other diameter are calculated by this formula.

n=10000times100/d n is test time and d is diameter
