High-alumina shaped refractory brick and preparation method thereof
The invention discloses a high-alumina shaped refractory brick and a preparation method thereof, and relates to the technical field of refractory bricks, the high-alumina shaped refractory brick comprises the following raw materials by weight: 50-70 parts of a mineral raw material, 20-30 parts of soft clay, 10-15 parts of graphene, 18-20 parts of silicon carbide, 30-40 parts of high-alumina bauxite, 10-30 parts of sulfurous acid paper pulp waste liquid, 12-15 parts of high-alumina aggregate, and 30-40 parts of water. According to the design, silicon carbide is added and can react with high-alumina vanadine, so that the corrosion resistance, wear resistance, thermal shock resistance and other properties of the product are greatly improved; the high-aluminum aggregate is added into the high-aluminum refractory brick, so that the fire resistance of the refractory brick can be remarkably improved, the high-aluminum aggregate has a relatively high melting point and thermal stability and can resist melting and softening at high temperature, the thermal shock resistance and thermal shock resistance of the refractory brick are improved, and the high-aluminum aggregate can form a compact structure in the solidification process; therefore, the strength and the stability of the refractory brick are enhanced.
本发明公开了一种高铝质定型耐火砖及其制备方法，涉及耐火砖技术领域，该高铝质定型耐火砖的原料按重量份组分为：矿物原料50‑70份、软质黏土20‑30份、石墨烯10‑15份、碳化硅18‑20份、高铝矾土30‑40份、亚硫酸纸浆废液10‑30份、高铝骨料12‑15份、水30‑40份，本设计通过碳化硅的加入可与高铝钒土进行反应，大大提高了产品的耐腐蚀性、耐磨性、耐热震性等性能；通过高铝骨料的加入到高铝耐火砖中，可以显著提高耐火砖的耐火性能，高铝骨料具有较高的熔点和热稳定性，能够抵抗高温下的熔化与软化，来提高耐火砖的耐热震性和抗热冲击性，并且高铝骨料在固结过程中能够形成致密的结构，并与基质紧密结合，从而增强耐火砖的强度与稳定性。
