摘要
A method of casting steel at a lower overheated temperature during continuous casting, wherein the inner surface of a tundish is heated to a temperature which approximately corresponds to the temperature of the steel in a ladle, the tundish is filled with steel, and the steel is poured into at least one mold. According to the invention a discharge spout of the tundish which opens above the reference level of the metal bath, prior to casting and during heating of the tundish is brought into a position which occupies the lowest point of the inner surface of the tundish, the heating of the tundish is continued until adjusting an approximately stationary thermal gradient between the inner and the outer surfaces of the tundish, and prior to pouring of the steel into the mold the tundish is brought into its casting position.
