Rolling steel ball

Rolling steel ball

Hot rolled steel ball is a new kind of rolling technology, is the process of  steel ball or grinding ball manufacturing technology breakthrough, is gradually replace the casting ball.

Forever is a leading manufacturer and exporter of rolling steel ball production line in China. We can not only supply complete rolling steel ball production line, but also we can give you efficient solutions.

Main production process for rolling steel ball

1.Factory inspection for bar material and diameter.

2. Using induction heating furnace to heat bar raw material to proper temperature  before rolling.

3. Red-heat billet rotates forwards between 2 special spiral-hole rollers and is continuously rolled into steel ball after being sent into ball rolling mill. Each set of ball rolling mill can be rolled into 40～120 steel balls per minute.

4. The rolled red-heat steel ball is immediately put into online heat treatment device for quenching when it is cooled to hardening heat, after quenching, it is cooled to proper temperature(50℃ below), and then put into online continuous tempering furnace for destressing tempering, so as to make steel ball obtain high and uniform hardness.

5. The qualified products after inspection are delivered to finished goods warehouse for customers after being packaged.
