。 Plug body 1 made of porous refractory material in the shape of a truncated cone
In a porous plug that essentially consists of a refractory sleeve 2 that covers the side surface of the plug body and a gas supply pipe 4 provided at the bottom of the plug body, a porous joint layer 3 is provided between the plug body and the sleeve. The porous plug is characterized in that its air permeability is lower than that of the plug body, but is selected to allow gas to pass through when the plug body is blocked.
