びストツパー。[Scope of Claim for Utility Model Registration] (1) The upper part of the immersion nozzle and the discharge hole of the immersion nozzle fixedly installed in the tundish are made of a breathable refractory material in which fine through holes are randomly embedded, and The upper nozzle and immersion nozzle of a tundish are provided with an introduction hole for introducing an inert gas into these breathable refractories. (2) The upper part and inner peripheral surface of the upper nozzle of the immersed nozzle fixedly installed in the tundish, the inner peripheral surface of the immersed nozzle, and the discharge hole are made of a breathable refractory material with fine through holes randomly embedded therein. The upper nozzle and immersion nozzle of a tundish are provided with an introduction hole for introducing an inert gas into these breathable refractories. (3) The stopper head, which fits into the upper nozzle of the immersion nozzle fixed to the tundish, is made of a breathable refractory material with fine through holes randomly embedded therein, and an inert gas is introduced into the breathable refractory material. A stopper for a tandice dish that has an introduction hole for this purpose. (4) The upper part of the upper nozzle of the immersion nozzle fixedly installed in the tundish, the discharge hole of the immersion nozzle, and the stopper head that fits with the upper nozzle are made of breathable refractory material with fine through holes randomly embedded therein. An upper nozzle, an immersion nozzle, and a stopper of a tundish, which are constructed with an introduction hole for introducing an inert gas into these breathable refractories. (5) The top and inner peripheral surface of the upper nozzle of the immersed nozzle fixedly installed in the tundish, the inner peripheral surface and discharge hole of the immersed nozzle, and the stopper head that fits with the upper nozzle are arranged with minute through-holes in them randomly. An upper nozzle, an immersion nozzle, and a stopper of a tundish, which are constructed of breathable refractories and are provided with introduction holes for introducing inert gas into each of the breathable refractories. (6) Claims (1), (2), (3), and (4) wherein the breathable refractory is obtained by adding combustible fibers to raw materials, mixing them, shaping them, and then firing them. or (5)
The upper nozzle, immersion nozzle and stopper of the tundish as described.
