Abstract
A molten iron containing vessel includes a refractory fireproof inner lining of dolomite bricks and bauxite bricks. The lining includes magnesia bricks positioned between the dolomite and bauxite bricks, thereby avoiding contact reactions between the dolomite and bauxite. A gas permeable brick member extends through an end portion of the vessel for injecting a gas into the molten iron contained therein.
