PURPOSE:To make width changing during casting possible at high speeds without generation of flaws by moving upper and lower cooling members mutually independently by the operation of oil hydraulic cylinders. CONSTITUTION:When all upper and lower cooling members 6a, 6b are advanced by the operation of oil hydraulic cylinders and are brought in abutment on the inner side face of one long side cooling member 4, the size in the width direction of the ingot is made the shortest. Thence, if necessary, a pair of the innermost upper and lower members 6a, 6b are retreated until these abut on stoppers, then the size in the width direction of the ingot is made long by as much as the thickness in the width direction of the ingot of a pair of the retreated upper and lower members 6a, 6b. The cooling water past a back frame 8 passes through the inside of the members 4 and stationary cooling members 5, whereby these are cooled. |
