First, prepare the round steel bar as the raw material. Please note that the composition should be provided to the manufacturer of the steel bar so that to get the right material.
Put the steel bars on the feeding device, after working; the bars go to the induction heating furnace to heat. And after reach to a specific temperature, go to the screw rolling working position start to screw. Formed steel balls go to the balls filter device to knock out the de-shaped balls; afterward, go to 1st quenching unit to quench, for some big size of the balls, need to 2nd quenching and then go to tempering furnace.
Above all is the standard process, but for different technical requirements, the producing process has some little change.
