Steel ball automatic production line process

1. After the round steel enters the factory, the material and diameter are tested and tested.

2. The steel ball billet is heated to a suitable temperature in a medium frequency induction heating furnace before rolling.

3. After the billet in red hot state is sent into the steel ball rolling mill, it rotates and advances between two rolls with special spiral pass, and is continuously rolled into steel balls. Each steel ball mill can roll 40 to 120 steel balls per minute.

4. When the rolled red-hot steel ball is cooled to the quenching temperature, it immediately enters the online heat treatment equipment for quenching. After quenching, it is cooled to a suitable temperature (below 50°C) and enters the online continuous tempering furnace for stress relief tempering treatment. Steel balls achieve high and uniform hardness.

5. After the qualified products are packaged, they are sent to the finished product warehouse and sent to customers.
