PURPOSE:To improve the poor thermal spalling resistance which is an intrinsic problem of a carbon-containing refractory. CONSTITUTION:The refractory is produced by compounding 50-95wt.% of a refractory aggregate containing one or more refractory raw materials, 5-50wt.% of a carbonaceous raw material and 1-20wt.% of a thermosetting resin and incorporating the obtained matrix with 1-50wt.% of carbon fiber or chemical fiber such as phenolic resin fiber (e.g. Novoloid, commercial name) attached with foil, powder or fiber of a metal, alloy, boride, etc., to prevent the oxidation. The default intrinsic to the texture of refractory can be eliminated and the oxidation of a refractory can be prevented to improve the poor thermal spalling resistance of conventional refractory. |
