    摘要: A hot repair material of refractory materials is provided and includes main materials and binding agents. The main materials include silicon carbide powders with six different particle sizes and a mass ratio according to particle sizes from large to small is 8:5:8:15:8:10. The binding agents include silicon nitride powders, a sodium silicate powder, an aluminum phosphate powder, a furfuryl alcohol, a silicone resin powder, a silica sol powder, an aluminum sol powder, a silicon oxide micronized powder, a vanadium oxide powder, a silicon powder, a borax and a rare earth oxide micronized powder, and a corresponding mass ratio is 20:10:4:1:5:1:1:2:0.5:0.5:0.5:0.5. The silicon carbide powders in the main materials have a good synergistic effect to improve strength of the repair material. The binding agents include low-, medium- and high-temperature binding agents for a full range of temperatures, so the repair material could gain strength continuously without a collapse temperature.
