摘要
PURPOSE: A method for manufacturing a low carbon steel billet and a low carbon steel billet manufactured by the same are provided to minimize depression and the cracks generated under the depression by controlling a heat rejection rate. CONSTITUTION: A low carbon steel billet is manufactured by continuously casting the molten steel including C of 0.05-0.15%, Si less than 0.5%, P less than 0.04%, S less than 0.04%, Mn less than 2.0%, Al less than 0.15%, remnant Fe, and inevitable impurity. The continuous casting operates at a speed of 1.55-1.90m/min, and the total heat of continuous casting is 1.50-1.75MW/mm^2.
