Zusammenfassung:PURPOSE:To prevent the surface crack due to ununiform cooling by measuring a temp variation of cast slab corner part with arranging an infrared sensor at secondary cooling zone and controlling a cooling speed based on the temp. CONSTITUTION:In the continuous casting of a high carbon steel containing >=0.70% C, an infrared sensor is arranged facing to a cast slab corner part at the prescribed interval in cooling zone, measuring a temp variation of the cast slab corner part at casting. A temp. of the cast slab corner part in total casting length is assumed by calculation. A cooling speed in the region having the assumed temp. of 850-700 deg.C is made to 10-30 deg.C/min, cooling with a cooling speed of the other region of secondary cooling zone of
