APPARATUS FOR SLAB CONTINUOUS CASTING

摘要

The purpose of the present invention is to rotate a submerged nozzle during casting, freely change the discharge angle of molten metal, and turn and stir molten metal in a slab mold. The apparatus for slab continuous casting according to the present invention supplies molten metal (3) into a water-cooled slab mold (2) from a tundish (1) through at least an upper nozzle (4), a slide valve (5), and a submerged nozzle (10) and solidifies the molten metal, said apparatus for slab continuous casting having a submerged nozzle quick replacement mechanism attached thereto. The apparatus for slab continuous casting is configured such that a discharge direction change mechanism (20) that is capable of freely changing the discharge angle of the molten metal (3) in a horizontal cross section during casting is disposed between a slide valve device (8) for opening/closing the slide valve (5) and the submerged nozzle (10).
