| 摘要 |
The present invention relates to a process for producing a crystalline siliceous refractory mass, which production process includes providing particulate constituents to be projected comprised of solid refractory particles comprising silica in the form of vitreous silica, and 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 degC. A refractory brick manufactured in such a manner exhibits a cristobalite structure and a deformation coefficient Ti0.5 of more than 1650 degC. |
