Detailed introduction:

1. Use a stepping heating furnace or induction furnace to heat steel rods with a diameter of 80mm;

2. Cut the steel rod into the fixed length we require;

3. Feed the cut hot steel bar pieces into the rapid hammer machine;

4. The rapid hammering machine hammers the cut steel rod into a ball shape;

5. Use a rolling machine to roll the spherical surface, making the spherical surface round and smooth;

6. After the steel balls are cooled, they are sent to the heating furnace for reheating.

7. The reheated ball is cooled to the required temperature and then quenched;

8. After the steel ball is quenched, it is sent to the tempering furnace. It takes 12 hours to complete the entire tempering process and completely eliminate the stress;

9. The steel balls are cooled to room temperature on the cooling plate, and then packaged for export according to customer requirements.
