Production Process

Steel ball rolling process
 

1.The material of rolling grinding steel balls is hot rolled low-alloy round steel bar with various chemical compositions, its dia. is equal to nominal dia. is steel balls;
2.Before rolling,the round steel bar heated to the suitable temperature in the continuous furnace;
3.Put the red-heated ball blanks into the ball rolling machine, then rotate and move between the 2 rolls with special spiral holes, and continuosly rolled into steel baIIs. Each machine can roll 60-360 balls per minute
4.Thet rolled red-heated steel balls immediately go into our special on-line heat treatment equipment for quenching, enable the steel balls to have the hing and uniform hareness.
5.The finished steel balls have the advantages of accurate dimension and geometry, good wear resistant and mechanical performance.
6.The qualified products are stored in the warehouse, and packed to the customers.

 



 Steel ball forging process
 

1.The material of forging grinding steel balls is hot rolled low-alloy round steel bar with various chemical compositions.
2.Before forging,the round steel bar is heated to the suitable temperature in the continuous furnace;
3.Put the red-heated round steel bar into the group of forging equipment, after many times forging,continuously forged into steel balls, 2-5 tons per hour;
4.After forging, The ball go into our special on-line heat treatment equipment for quenching, enable the steel balls to have high and uniform hardness;
5.The finished steel balls have the advantages of accurate dimension and geometry, good wear resistant and mechanical performance.  
6.The qualified product are stored in the warehouse, and packed to  the customers.
