Forged Steel Rings

Precision steel rolled rings are manufactured at CHW Forge to closed tolerances which promotes minimum wastage of material and energy. The seamless rolled ring forging is produced on an automatic 4000 MT hydraulic press to form a hollow “donut”. This donut is heated above the recrystallization temperature and placed over the idler or mandrel roll. This idler roll then moves under pressure towards a drive roll that continuously rotates to reduce the wall thickness, thereby increasing the diameters (I.D. and O.D.) of the resulting ring.
