ABSTRACT:
A solid non-permeable refractory plug has a spaced stainless steel and/or ceramic jacket and is located in a pocket block for incorporation in the normal refractory brick lining of a ladle to provide a passageway through which gas can be introduced into the molten metal. The stainless steel and/or ceramic jacket extends above the refractor plug and the pocket block to form a hot metal dam that protects the passageway from metal and/or slag penetration during the filling of the ladle with molten metal.
