Abstract
A complex method involving a technology and equipment for spray quench ing is used for improving the quality of the metal of back-up rolls of high-load mills. The accelerated cooling by sprayed water in the proc ess of final heat treatment of back-up hot-rolling rolls increases the surface hardness, accelerates the structural transformations over the cross section, and reduces the total heat-treatment time as compared to normalizing.
