METHOD FOR MANUFACTURE OF ROLLED PRODUCTS

摘要

FIELD: ferrous metallurgy, mainly, thermal hardening of reinforcement bars in line of continuous section mills. SUBSTANCE: rolled products are manufactured from low-carbon steel with carbon content within 0.12-0.24%, and interrupted hardening is effected up to bulk temperature of 540-600 C; with content of carbon in steel rising within the indicated range per 0.02%, the bulk temperature is increased by 15-20 C. EFFECT: higher efficiency. 1 tbli
