Abstract Abstract： Transverse corner cracks on slabs of Nb microssloyed steel has been a serious problem in the continuous casting of SanXi XinLinGang Iron & Steel Co., Ltd, Surface temperature of the continuous casting slabs was systematically measured in the study with the device developed by the author. Surface temperature of the continuous casting slabs at LinGang Steel should be raised to higher than 1020℃ to effectively avoided the occurrence of the transverse corner of the slab in Q460C steel.
