Abstract
Position sensors at an inlet of a mold cavity defined by upper and lower block molds detect distances from the passing upper and lower block molds. In response to outputs from the position sensors, any deflection of the leading end of the tundish nozzle, which can be inclined with respect to the melt outlet of a tundish, toward the upper or lower block molds defining the mold cavity is detected by a control device to generate a drive signal which is delivered to a hydraulic cylinder adapted to incline the tundish nozzle by extending or retracting the rod thereof, whereby the gaps between the leading end of the tundish nozzle and the upper and lower block molds are maintained uniform.
