Hot-rolled steel ball production line Introduction
Steel ball skew rolling mill machine use spiral hole typed mold by skew-roll forming process to produce wear-resistant steel ball, bearing steel ball and other metal balls. It can also be used to produce other rotating body parts such grinding steel bar. The principle sketch of skew rolling process as below:
The Skew rolling mill machine used semi-closed body frame, the frame has good rigidity, compact structure, convenient mold changing, easy adjustment and high precision of rolling products. The complete machine consists of main motor, reducer, universal coupling, skew rolling mill machine, induction heating furnace, control cabinet and other parts. With high production efficiency, high material utilization, product quality and other advantages. Grinding ball production line structure as shown:
