METHOD FOR HOT ROLLING OF STEEL STRIPS WITH CARBONITRIDE REINFORCEMENT
FIELD: manufacture of rolled products. SUBSTANCE: method involves heating slabs to temperature of 1.100-1.250 C and holding for 3-5 h; providing multiple-pass rough rolling at total reduction of at least 80% and final temperature of 1.020-1.090 C, multiple-pass final rolling at total reduction of at...
