Abstract
A refractory block for continuous casting is disclosed comprising a unitary assembly including a plate brick having a top, bottom, sides and a passageway therethrough; a gas permeable porous brick having a top, bottom, sides and a passageway therethrough, where the top of the porous brick is attached to the bottom of the plate brick, a gas pool for containing gas surrounds the sides of the porous brick, and a submerged nozzle having a top, bottom and sides, where the sides have shoulder portions, has the top of the submerged nozzle attached to the bottom of the porous brick. A metal casing surrounds the unitary assembly so that the metal casing surrounds and supports a portion of the sides of the plate brick, a portion of the bottom of the plate brick, the sides of porous brick, and a portion of the sides of the submerged nozzle, including the shoulder portions. The metal casing further includes gas feed and discharge pipes therethrough in communication with the gas pool.
