Forged steel rolls include work and back-up rolls for cold rolling. For this purpose, the state-of-art facilities are employed in manufacturing these rolls, of which are steel-making (EAF), refining (ESR or LF/VD) and forging (3150t hydraulic press) equipment to produce the high quality forged steel blanks. As for heat treatment equipment, the reproducibility of barrel hardness and the depth of hardness are guaranteed by mean of the computer control; As for the heat treatment procedure, we take on the pre-heat-treatment, the specific induction-heating quenching (progressive or integral), the cold treatment and the tempering, so as to provide the rolls with high and homogeneous hardness in the work layer with superior wearability, high toughness and sufficient resistance to accident, the depth of hardened layer may be over 30mm, so when these high quality work rolls are applied on the modern wide cold strip mills at home and abroad, the satisfactory performance have been obtained.
