Zusammenfassung:The present invention provides an improvement of fire-resistant material for copper-anode furnace flow groove. The present invention is characterized in that the basic components are 50 to 80 weight percent of SiC, 0 to 40 weight percent of fire-resistant material containing Al2O3, 1 to 20 weight percent of micro powder, 1 to 4 weight percent of C, 1 to 3 weight percent of Si, 0.5 to 5 weight percent of cement binder. The chemical component after mixing is 48 to 78 weight percent of SiC, 10 to 40 weight percent of Al2O3, 4 to 8 percent of SiO2, less than or equal to 6 weight percent of C, less than or equal to 3 weight percent of CaO, and less than or equal to 6 weight percent of Si. Compared with the prior art, the present invention has the characteristics of good thermal shock resistance, good high-temperature erosion resistance, non-stick liquid copper and copper slag, convenient cleaning, long service life and so on. The one-time service life reaches above 20 furnaces with copper. Besides, the constructio
