ABSTRACT OF THE DISCLOSURE The method of sequential continuous-casting of the different grades of molten steel according to the present invention comprises the steps of: stopping the pouring of a first grade of molten steel into a mold; immersing a cooling material consisting of steel stock or a steel structure slightly smaller than the inner cross- sectional area of the mold by way of guiding jigs fastened to said cooling material; forming a solidified phase around said cooling material; and merging said solidified phase in a solidi- fied shell developed from the wall of the mold to form a solidi- fied layer shutting the upper portion off the lower portion of the first grade of molten steel. According to the process, the pouring the second grade of molten steel is started before the solidified layer for shutting the upper portion off the lower portion of the first grade of molten steel as described above and the surface of the first grade of molten steel is solidified completely, and at the same time, the drawing of the cast slab is started again and the change-over to the normal continuous casting of the second grade of molten steel is effected.
