How we make 100/125/140mm Forged Steel Grinding Media Balls ?
Detailed explainations on above production flow on 125mm Forged Steel Grinding Media Balls:
1.Use step up heating furnace or induction furnace to heat on 80mm Dia steel rod;
2.Hot cutting machine cut the heated steel rod to fixed length we request;
3.Use magic hand to pick up cutted hot steel rod piece and feed to quick hammer machine;
4.Quick hammer machine hammer the cutted steel rod to a ball shape;
5.Use rolling machine to get round and smooth ball surface;
6.Cool the ball, then send into reheating furnace to reheat on ball to organize the microstructure of the steel ball;
7.Reheated ball will do the quenching treatment after cool to requested temperature;
8.The ball after quenching treatment, will send into tempering furnace, it will take 12 hours to finish the entire tempering progress on 125mm balls for complete stress relief;
9.Tempered ball will cool to room temperature on cooling plate, then do the export packing upon client's request.
