Abstract
The present invention provides a method for casting a slab with good cast surface quality. The method includes pouring molten metalinto a moldfrom one of the paired shorter sides of the moldwhile allowing superheat ΔT [° C.], which is a temperature difference obtained by subtracting the melting point Tm [° C.] of the raw material from the temperature Tin [° C.] of the molten material on the surface of the molten metal in the mold and at the pouring point of the molten metal, to satisfy the following Formula (1) and Formula (2):0.0014Δ+699.45>800   Formula (1)0.0008Δ+853.02<1250   Formula (2)
