Abstract

PURPOSE:To cheaply manufacture the title sheet with superior cold workability and strength-ductility balance by quenching steel products of a specific compsn. consisting of C, Si, Mn, sol. Al, and the balance Fe in two steps, followed by coiling. CONSTITUTION:Steel consisting of C; 0.06-0.25%, Si: 0.15-1.50%, Mn; 0.30- 2.00%, sol. Al<=0.1%, and the balance Fe and inevitable impurities is passed through a finish rolling stand at 800-900 deg.C and immediately quenched at the tip of a runout table to the temp. range of Ar3-Ar1 at a cooling rate above 80 deg.C/sec. During passage on the table, the rolled sheet is held in the temp. range of Ar3- Ar1 for 1-20, pref. 3-10 sec and quenched again to below 450 deg.C at the tail end of table at a cooling rate above 80, pref. above 150 deg.C/sec, followed by coiling.
