Refractory brick prepared from industrial solid waste and preparation method of refractory brick

The invention discloses a refractory brick prepared from industrial solid waste and a preparation method of the refractory brick. The refractory brick is prepared from the following raw materials in parts by weight: 30-45 parts of vanadium slag with the particle size of 1-3mm, 15-20 parts of vanadium slag with the particle size of 0.088-1 mm, 6-25 parts of vanadium slag with the particle size less than 0.088 mm, 15-34 parts of silica fume, 2-5 parts of V2O5, 5 parts of phosphoric acid, and 6-12 parts of water. According to the method, the metallurgical waste vanadium slag with high additional value is adopted as a main raw material, a single aluminum source is provided, the high-alumina refractory brick is obtained through forming and sintering under the assistance of silica fume, and the refractory brick prepared through the method has high refractoriness and good thermal stability. 本发明公布了利用工业固体废弃物制备的耐火砖及其制备方法，该耐火砖是由下述重量份的原料制备而成：粒径大小在1-3mm的钒渣30-45份；粒径大小在0.088-1mm的钒渣15-20份；粒径＜0.088mm的钒渣6-25份；硅灰15-34份；V2O52-5份
