摘要： PROBLEM TO BE SOLVED: To provide a hot casting repair material capable of forming a cast, without scattering, at an inclined site that needs to be repaired when thrown against the site under a situation where the operation rate is high and only a short time can be spared for repair. SOLUTION: From 5 to 30 pts.mass substance forming a carbon bond under heat and 0.1-5 pts.mass nonaqueous solvent are compounded with 100 pts.mass grain size-controlled basic refractory aggregate. The resulting composition enables moderate wetting of the basic refractory aggregate and the substance forming the carbon bond under heat by the nonaqueous solvent at compounding and kneading and results in coating of a coarse grain of the basic refractory aggregate with a fine powder. This prevents scattering of the fine powder when the composition is thrown into a furnace and crashes into a high-temperature wall furnace and enables the composition to retain the designed grain size composition and stay at the site to exert a shape retention property.
