Abstract

PURPOSE:To uniformize thickness of a strip and to improve the surface characteristic by measuring molten metal quantity in a tundish by on-line and PID- controlling position of the stopper rod based on deviation of measured value to the aimed value. CONSTITUTION:At the time of casting the strip 28 by supplying the molten metal 10 from molten metal holding device 16 through the tundish 12, the molten metal quantity in the tundish is measured by the on-line. The position of the stopper rod 14 is PID-controlled based on the deviation of the measured value to the aimed value. By this method, the thickness of the strip is uniformized and the surface characteristic is improved.
