Abstract
PURPOSE:To prepare a hot rolling steel plate with high Lankford value and high ductility by subjecting an extra low carbon steel added by Ti, Nb to hot rolling in a specific temperature range. CONSTITUTION:A steel segment comprising, as wt%, C; <=0.02%, Mn; <=0.5%, Al; 0.01-0.05%, Ti; 0.01-0.20%, Nb: 0.005-0.05%, a balance of iron and inevitable impurities is heated to above 100 deg.C and subjected to hot rolling of which cumulative draft at below 1000 deg.C is 80% and a finish temperature is above Ar3 point. If a hot steel segment obtained by cogging mill or continuous casting is introduced into a heating furnace without lowering a temperature to below Ar3 point in place of heating of above 1100 deg.C and heated to 950-1100 deg.C, heat energy is saved and productivity is enhanced.
