    Abstract: A refractory block which has a construction wherein the outer peripheral surface of a unitary assembly of plate bricks and an immersion nozzle is directly encompassed by a unitary metal case. It is also possible to employ a construction wherein plate bricks stored in a metal case are bonded to the dowel portions of the immersion nozzle stored in a separate cylindrical metal case through mortar and the metal cases are welded integrally to each other, a construction wherein a unitary refractory block of the plate bricks and the immersion nozzle is encompassed by a unitary metal case, or a construction wherein the unitary refractory block is fitted to a unitary metal case through an amorphous refractory. The unitary refractory block may be a combination of different kinds of refractories, and it is further possible to employ a construction wherein the plate bricks and the immersion nozzle are fitted into a unitary metal case with porous bricks sandwiched between the plate bricks and the immersion nozzle, and feed/discharge pipes are so disposed in the porous bricks as to penetrate through the metal case.

    Abstract: A process for producing silica brick by firing silica stone mainly comprising silica and containing 0.2 to 5 wt % of solidified molten soda lime silicate added thereto, whereby silica brick with a lowered content of residual quartz can be produced readily and efficiently even by using a silica stone which difficultly causes the transformation of quartz. The process comprises crushing silica stone, adding thereto solidified molten soda lime silicate and a binder, molding the mixture, and firing the molding at 1350 to 1500 °C to cause a reaction between the silicate and the silica in the silica stone to thereby cause rapid transformation of the silica into cristobalite and tridymite.
