PURPOSE:To prevent the sweating phenomena of ingots and to improve the quality and performance of the ingots by controlling casting conditions in such a way that the thickness of the ingots removed from molds have the nearest possible thickness of the inside dimensions of the molds. CONSTITUTION:In a continuous casting device which charges molten metal through a charging nozzle 7 into a continuous mold 5 formed by putting an endless belt 3 between a rotary wheel 1 for casting provided with a hollow groove on the circumferential surface and a rotary wheel 2 for guiding and bringing a belt 2 into moving contact with the circumferential surface in a part of the wheel 1 by means of a push roll 4, cools and solidifies the molten metal in the mold 5 by injecting water from a cooling zone 6 provided in the outside part of the mold 5, and coiling the resultant ingot 8 with a coiler 13 through hot rolling mills 12, the thickness of the ingot 8 is measured with a thickness measuring device 9, and the flow rate of the cooling water from the zone 6 is controlled by keeping the other casting conditions constant so as to control the thickness of the ingot 8 to >=98.8% the thickness of the inside dimensions of the mold 5. |
