PURPOSE:To minimize the adverse influence that the pouring flow gives to a thin billet in the stage of starting casting by providing a pouring port for a molten metal to either one of stationary plates for short sides. CONSTITUTION:A nozzle 11 is connected to either one or both of stationary side plates 6, 7 and pouring ports 11a... are opened. The molten metal in a tundish 12 flows through the nozzle 11 and through the ports 11a, thus entering the inside of a casting space S in the form of horizontal flow. Solidification progresses successively inward from the areas adjacent to metallic belts 4, 5 forming solidified shells in precedence, then the solidified billet is drawn out downward by a dummy bar and the rotation of the belts 4, 5. The level of the ports 11a which discharge the molten metal into the space S is thus made lower and the molten metal striking against the surface of the metallic belts in the initial period of pouring is considerably decreased. The erosion and thermal strain of the belts are thus eliminated. |
