PURPOSE:To improve the productivity by arranging a dummy bar having the width less than the min. width of a casting slab and also arranging a sealed plate at the lower end of a mold. CONSTITUTION:The dummy bar 8 having the width with a little narrower than the min. width of the casting slab as castably, is inserted into the mold, and also the sealed plate 9 is set at the lower end of the short side mold 6 and shifted toward the arrow direction 11 by cylinders 10 to seal. In advance, the short side mold 6 is set at necessary width and the sealed plate 9 is shifted to contracting width the dummy bar 8 by the cylinder 10, and next, the coolant 13 for the molten metal on the sealed plate 9 and the dummy bar 8 is charged to pour the molten metal 2. In this way, at the time of starting the casting as changing the width of the casting slab, the dummy bar 8 head is no necessary to change. Therefore, as operational ratio of the casting apparatus is improved, and the productivity is improved.
