Abstract:
PCT No. PCT/BE95/00108 Sec. 371 Date May 27, 1997 Sec. 102(e) Date May 27, 1997 PCT Filed Nov. 23, 1995 PCT Pub. No. WO96/16917 PCT Pub. Date Jun. 6, 1996A process for producing a crystalline siliceous refractory mass includes providing particulate constituents to be projected comprised of (1) solid refractory particles comprising silica in the form of vitreous silica, and (2) solid combustible particles comprising silicon particles; projecting the particulate constituents with gaseous oxygen against a surface under ceramic welding conditions effective to cause a reaction between the solid combustible particles and the gaseous oxygen to occur against the surface, thereby releasing the heat of reaction against the surface so that a coherent refractory mass comprising cristobalite is formed, wherein the surface against which the solid refractory particles are projected is at a temperature of at least 1000 DEG C. The process can be used to manufacture refractory bricks or blocks, to repair furnaces, or to repair worn surfaces of a siliceous refractory material.
