METHOD FOR PRODUCING HOT-ROLLED STRIP FOR DEEP DRAWING

摘要

FIELD: metallurgy. SUBSTANCE: method involves hot rolling; intensified cooling; winding strip into roll; cooling roll; unwinding roll and cutting it into measured lengths; normalizing in two stages: first stage at A(C3) + 30-50 C, second stage at temperature ranging between critical points of A(C1) and A(C3). Method allows metal with completely spheroidized pearlite structure to be produced. EFFECT: increased efficiency of thermal treatment process and reduced power consumption. 1 tbl, 1 ex
