Abstract
PURPOSE:To prevent serious trouble, such as breakout, by interposing the specific reinforcing material extending above and below with a fitting tip part of a spindle as center to reinforce neck part of a tundish stopper. CONSTITUTION:Plural pieces of inorganic fiber element wires of carbon fiber, alumina fiber, etc., having in the range of diameter from 2mum to 3.5mm are set over >=30mm above and below respectively with the lower end of female screw 6 for fitting the spindle at the neck part 4 as center to constitute the reinforcing plate 5. By this method, structural strength at the time of operating the tundish stopper 1 is improved to stabilize the operation, and the operation for removing non-metallic inclusion is executed and even in the case of applying the shock, the trouble is not developed and the stable operation can be executed.

This is to control the amount of molten metal poured into the mold according to casting conditions, and the mounting spindle is subject to adverse effects such as the impact received from the molten metal during control and the impact caused by the fitting of the immersion nozzle with the morning glory part. This invention relates to a tundish stopper for continuous casting, which has a joint or neck portion reinforced and stabilized.
