摘要： A steel continuous casting method that can effectively reduce center segregation occurring inside a cast piece is proposed. This steel continuous casting method is characterized in that cooling of a cast piece is performed with a water volume density per surface area of the cast piece in a first section set within a range of 50 to 2000 L/(m2 × min) or lower. The first section is a range along a cast piece withdrawing direction in a continuous casting machine, from a start point at which an average value of a solid phase ratio along a thickness direction at a final solidified part in a cast piece width direction is 0.8 or lower to an end point at which the average value of the solid phase ratio along the thickness direction at the final solidified part in the cast piece width direction is higher than the solid phase ratio at the start point but not higher than 1.0.
