特徴とするガス吹込み用ポーラスプラグ。 In a porous plug for gas injection, the outer part is made of a dense refractory and the inner part is made of a breathable refractory, so that gas can be freely blown into the plug. Gradually change the required cross section in the middle of the refractory from a polygonal shape to a circular shape or from a circular shape to a polygonal shape, so that the breathable refractory is integrally formed from the upper part to the lower part, and the lower end portion is formed into a conical shape. A porous plug for gas injection.
