Forged grinding ball production process overview
1.High quality raw material steel rod well prepared .
2.Shearing the steel rodto semi-finished steel rod by specified length.
3.Beforeforging/rolling the semi-finished steel rod, it need to be heated to proper temperature in the continuous heating furnace.
4.After red state of steel rod is fed into the ball rolling device, it will rotate between the two rollers with special
spiral groove, and then continuously rolling as steel ball. Each ball rolling mill can roll 60-120 steel balls per minute.
5.After rolling Red state steel ball will immediately put into on-line heat treating machine for quenching-tempering treatment,
make steel ball has high and even hardness.
