2. Producing process
1. After checking and testing the round alloy steel bar material,the production can be started according to the size
of the steel ball
2.The steel forging is heated to a certain temperature by intermediating with frequency furnace to ensure the
effective generation of variables in the forging;  
3.The red-hot steel forging is sent into the air hammer and processed by skilled operators.  
4.After forging the red hot steel ball immediately into JUNDA specially designed heat treatment equipment
for quenching and tempering heat treatment, the high and uniform hardness value of the steel ball can be ensured.
