| A one-piece, integral blast furnace shell, the totality of which is self-supporting and which extends continuously, without interruption from the top of the stack to the bottom of the hearth. No mantle; no columns. A fluid-cooled internal metallic lining for a blast furnace. The lining extends continuously, without interruption, and without sharp angular changes, from the top of the stack to the lower part of the bosh. The lining is movably mounted to accommodate thermal changes in furnace.
