Product name: Steel ball production,steel ball production line

Process description

1)Billet  preparation:

 

All ball billet for 6m hot rolled bar.
According to the size and type of storage in different storage rack.
Define a unique batch number for each batch.
Sampling inspection for each batch of stock.
According to the chemical composition of the test blank, as well as the steel ball hardness requirements.

2)Heating:

Blank lifted by crane to the loading platform, the feed rollers automatically feed into the intermediate frequency furnace heated to the desired temperature rolling

3)Rolling

According to the material composition and the hardness of steel ball, the rolling temperature is established, and the average rolling temperature is about 1000~1100. The reddest of steel bars through the roller automatically sent to the ball mill, in two with special helical hole between the rolls rotate and move forward, and is continuously rolled into a ball.

4)Cooling

Eligible ball rolled into the cooling conveyor

5)Hardening:

After the ball through the conveyor naturally cooled to a temperature suitable to the Ball separator, go screw quenching quenching tank. Its speed can be adjusted manually via the inverter.

6)  Tempering (tempering)

After the completion of the steel ball, into the heat preservation barrel to temper.

7)  Cooling platform

 

After the steel ball is tempered, the cooling platform is entered
