WEIR REFRACTORY CONSTRUCTION METHOD FOR INDUCTION HEATING TYPE TUNDISH AND WEIR REFRACTORY REPAIR METHOD FOR WEIR REFRACTORY

摘要

PROBLEM TO BE SOLVED: To suppress the generation of cracks with complicating the configuration of the whole of a weir refractory.;SOLUTION: A method of the invention is the method for applying a weir refractory 11 to an induction heating type tundish 1 provided with the weir refractory 11 having channels 12a that make molten steel pass through in both side bottoms in the width direction between the hot-water receiving side 2 that receives molten steel from a ladle and the casting side 3 that discharges the molten steel into the casting mold. Firstly, castable refractories 13,14 are cast into the periphery of a coil duct 5 to make an iron core for induction heating pass through to apply a castable refractory layer. Next, after block refractories 16-18 are disposed on the side of the runner refractory 12 of the castable refractory layers 13,14 and on the side of the hot-water receiving side 2 and the casting side 3 on the utilization side of the castable refractory layers 13,14, a castable refractory 15 is applied to a gap between these block refractories 16-18 and between a runner brick 12 and the castable refractory layers 13,14.;COPYRIGHT: (C)2016,JPO&INPIT
