Abstract

PURPOSE:To cast a metal which does not cause any surface defect such as sweating, reverse segregation and the like by providing an electromagnetic coil in the lower part of a bottomless mold and applying side pressure by electromagnetic repulsive force to a cast ingot at the time of semicontinuous casting of the metal by drawing the cast ingot from the bottom part of said mold. CONSTITUTION:A dummy bar 12 is beforehand located in a bottomless mold 2, and the bar 12 is lowered with supplying of molten metal 3. During this time, the melt level in a spout 1 is measured at all times by a melt level measuring device 4 and the shape of a cast ingot by a cast ingot shape measuring device 10, respectively, and the signals thereof are inputted to a control arithmetic device 5. While said level is stable, the device 5 emits a command by the equation I. When the level is fluctuating, the change is measured with the device 4, and is fed forward to the command value MV0 of the equation I, whereby controllability is improved. Namely, it is corrected like the formula II. Since this method acts pinching force upon the solidified shell, a cooled mold 7 is short, hence, the solidified shell formed there withstands the static pressure of the molten metal in the inside although it is extremely thin.
