PURPOSE:To enable safety and speedy width change by casting again under the condition that the movable wall is set to the specified position where the width is already changed by throwing the cooled material in the molten bath to separate the movable wall of the mold and setting the specially fixed supporting plate to the ingot piece after stopping the cast. CONSTITUTION:Stop the cast and pull up the tundish nozzle. Then, throw the coolings 4 such as shots in the molten bath. Further, arrange the cutting pieces 5 of steel pipe by turning them sideways. Sink about half diameter of pipe under the molten bath. Separate the movable wall 2, 2 of the mold and insert a pair of Z- letter type steel supporting plate 6, 6 between the movable wall and ingot piece 3 to closely connect between the end portion along with the shoulder section of ingot piece by using the connecting rod together with connection to the side surface 3 of the ingot piece. Pull down the ingot piece to the suitable distance by driving the pinch roller and adhere the movable wall of the mold closely on the receiving bottom 9, 9 on the end portion of the supporting plate. Then, after throwing the cooling material 4 on the receiving bottom, lower the nozzle and pour the hot water to cast again. |
