Forged steel work rolls for hot rolling mills
Forged work rolls from carbon tool steel are notable for high hardness and wear resistance. Depending on operation conditions resistance to fire cracking formation, as well as high stability to surface cleavage formation particularly at high and uneven pressure on roll barrel surface are provided via complex chromium, molybdenum and vanadium alloying. Roll ends may be either wobbler-shape, flat, cylindrical (with spline grooves or key grooves).
