Anti-erosion silica brick for carbon calcination furnace
The invention relates to an anti-erosion silica brick for a carbon calcination furnace and belongs to the field of refractory materials. 25%-35% of calcined silica with the granularity of 1-2.36 mm, 15%-25% of calcined silica with the granularity of 0.5-1 mm, 13%-23% of calcined silica with the granularity of 0.2-0.5 mm, 20%-30% of calcined silica with the granularity of 0.075-0.1 mm and 5%-10% of calcined silica with the granularity of 0-0.045 mm are taken as main raw materials, the anti-erosion silica brick further comprises 4%-8% of a combustion aid, 1%-2% of a compound additive, 1%-2% of an enhancer and 2%-6% of a binding agent. The calcined silica is adopted, the purity is high, quartz in a part of the raw materials is converted into tridymite and cristobalite in the sintering process, few mineralizing agents are additionally added, the content of SiO2 is high, the high-temperature performance of the product is excellent, the compactness and the yield of finished products are improved, the erosion resistance is high, and the service life of the carbon calcination furnace is greatly prolonged.
