Provided is a method for estimating a carbon pick-up (Cp; ppm) flowing from a mold powder layer into molten steel during a continuous casting, calculated by the below formula which uses the thickness (Lt; mm) of the mold powder layer. Herein, a is a coefficient value of 0.25 to 0.3, and b is a constant value 6.0 to 7.0. [Reference numerals] (AA) Start; (BB) End; (S10) Measure the initial content of molten steel; (S20) Measure the thickness of a liquid layer; (S30) Calculate the predicted carbon increase of the molten steel; (S40) Calculate the final carbon content of the molten steel |
