摘要： PROBLEM TO BE SOLVED: To manufacture a cast piece with superior surface quality without causing an intergranular crack at an austenite grain foundary near the surface, when casting a boron-containing steel by a continuous casting method. SOLUTION: The cast piece is controlled such that its shell thickness at the bottom end of casting mold stays between 7-10 mm, and is further subjected to rapid cooling at a cooling speed of 100°C/sec or more in a second cooling zone starting immediately below the mold, until the temperature at a position 0.5-2 mm deep from the surface at a corner of peripheral face of the cast piece reaches 1,000°C. Thus, precipitation of massive MnS and BN aligned along an austenite grain boundary and precipitation of ferrite in a film state are depressed so that a crack on the surface of the cast piece at the bending and straightening positions is prevented.
