PROBLEM TO BE SOLVED: To produce cast slabs having mixing part so as to be minimized by preventing the mixture of the previous heat and the next heat as less as possible, in the continuous casting for different steel kinds. SOLUTION: The casting speed of the previous heat before 6-10 min of supplying-stop to the previous heat is gradually decreased and also, exothermic powders 11 are charged into a mold 5 and a sequence block 7 is charged into the molten steel pool of the previous heat after charging this exothermic powder 11 and thereafter, the next heat is poured into the mold 5.
