High Speed Steel(HSS)Rolls are composed of high alloy and high carbon HSS outer shell with either a forged steel or nodular iron core.This type of molten metal for HSS is poured along the core material continuously or spun cast.HSS provides excellent hardness,wear resistance,and high temperature properties.
The advantages of these high-speed rolls are:
1.The high-carbon,high-alloy outer shell high hardness at high temperatures,providing excellent wear resistance.
2.The outer shell has a fine microstructure without gravity segregation due to its special casting method.
3.The boundary between the outer shell and core is combined by metallic diffusion.
Applications for these rolls includes hot strip mill finishing train,rod and bar mill finishing,and universal mill finishing.Because of the excellent properties of these rolls,new applications are continuously being investigated and tried.
