Abstract

PURPOSE:To improve collecting efficiency of non-metallic inclusion by arranging a non-metallic inclusion absorbing body made of porous refractory at almost center part of molten metal receiving chamber partitioned with weirs in a tundish and developing vortex of molten metal around the above absorbing body. CONSTITUTION:The porous non-metallic inclusion absorbing body 20 made of foam ceramic having truncated cone shape, is arranged at almost center part of the molten metal receiving chamber 4 at molten metal pouring side partitioned with upper weir 2 and lower weir 3 in the tundish 1 for continuous casting. At the time of discharging the molten metal 8 into the molten metal receiving chamber 4 from a ladle 7 through discharging hole 21 of a submerged nozzle 6 opening at side face facing to the absorbing body 20, the molten metal in the receiving chamber 4 caused by the discharging flow A of the molten metal 8 obtain rotating force. In this result, the circular flow or the vortex B is developed around the absorbing body 20 and the non-metallic inclusion in the molten metal can be efficiently collected on the absorbing body 20.
