PROBLEM TO BE SOLVED: To improve a yield ratio of the cast slab in the continuous casting equipment having a plurality of strands and to reduce workloads imposed on operators at the casting terminal stage. SOLUTION: In the continuous casting equipment having three strands or more, when the molten steel injection is completed into a tundish by the last ladle, the molten steel weight remained in the tundish is calculated from the expected casting lengths of cast slabs to be cut and the final scrap volume of cast slabs to obtain the number of expected cast slabs in each strand and, at the time when the number of which is one piece fewer than the total expected number of cast slabs is extracted, the molten steel injection into the strands in both sides is stopped.
