徴とするボーラスプラグ。 Plug body 1 made of porous refractory material in the shape of a truncated cone
, an iron skin 4 that airtightly covers the lower side and bottom of the plug body, a refractory sleeve 2 that covers the side of the plug body from the outside of the iron skin, and a gas supply provided at the bottom of the plug body through the iron skin. In a porous plug essentially consisting of a tube 3, there is a donut-shaped hole on the outside of the iron skin on the bottom surface, the outer diameter of which is approximately the same as the outer diameter of the bottom surface of the sleeve, and which has a hole in the center for passing the gas supply pipe. A bolus plug characterized by comprising a cushioning material 6 and a reinforcing material 7 made of a steel plate and having approximately the same shape as the cushioning material.
