摘要
PURPOSE:To enable changing of a billet width without interrupting casting by joining the blocks which are positioned in upper places so as to place successively the same from above while moving stationary side plates by moving a moving mechanism for said plates. CONSTITUTION:Another pair of stationary side plates 8, 8' (width l) are placed on stationary side plates 7, 7' (width L) in the stage of changing the ingot width L to (l). A chain 9 of a moving mechanism is fed forward in synchronization with the movement of a circulation body, by which the plates 7, 8 are moved in the direction of charging and are brought to the position where stationary side plates 8, 8' in the upper place come to the position of the molten metal level, thus creating the state of connecting a solidified shell 16 having the width L and a solidified shell having the width (l) into one body in the casting space. The solidified shell billet of the width (l) is produced in the final and at the same time, the plate 7 which is unnecessary one is retreated by the actuation of a hydraulic cylinder 14 and is further unclamped 10 into the stand-by state.
