Tube Mill Rolls Hardening And Tempering

Mill Roll Hardening Systems are becoming increasingly popular with the expanding development of cold mills which subject the rolls to high stresses. These systems are used to obtain rolls with high strength and resistance to surface wear. Induction heating has greatly contributed to improvements in hardening depth, with subsequent improvement in distribution of residual stresses.
