Abstract

PURPOSE:To prevent the solidification and leakage of the molten metal in a side dam by using a porous refractory material as the side dam forming a well of molten metal, supplying an inert gas to this anf forming bubbles on the inside surface of the side dam. CONSTITUTION:Molten metal 7 in a tundish 1 is tapped 8 continuously through a tapping nozzle 2 into a well 9 of molten metal formed by water cooled rolls 3, 3' and a side dam 4. The molten metal in the well 9 is cooled, solidified and rolled by said rolls 3, 3' to a sheet 10, which is pulled at a prescribed speed 11 with guide rolls 5 and pinch rolls 6. The dam 4 consists of a porous refractory material 4C in contact with the molten metal, a heat resistant refractory material 4f and a frame 4a made of cast iron fitting these. The material 4c consists of Hi-Al2O3, etc., is brought into pressure contact with the rolls 3, 3' by means of liquid pressure cylinders 4b via a frame 4a and generates a large number of bubbles 15 of an inert gas such as Ar supplied through a hose 13 and a lead-in pipe 4d on the inside surface thereof.
