Method for controlling inclusion composition of Ca-containing aluminum killed steel

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling a debris composition of a Ca-containing aluminum-killed steel which is capable of highly precisely adjusting the debris composition to a target value.SOLUTION: A method for controlling a debris composition of a Ca-containing aluminum-killed steel includes: before pouring molten steel containing Ca into a continuous casting tundish, analyzing a T.O concentration and a Ca concentration in the molten steel; and controlling the T.O concentration in the tundish according to their respective analytical values.
