Slag-corrosion-resistant aluminum silicon carbide carbon brick and preparation method thereof
The invention relates to the technical field of aluminum silicon carbide carbon bricks, and particularly discloses a slag-corrosion-resistant aluminum silicon carbide carbon brick and a preparation method thereof. The slag-corrosion-resistant aluminum silicon carbide carbon brick is prepared from the following raw materials: 60 to 80 parts of high-aluminum vanadine, 15 to 20 parts of silicon carbide, 2 to 8 parts of boron nitride, 1 to 4 parts of mesoporous silicon dioxide, 3 to 6 parts of binder and 1 to 2 parts of lubricating dispersant, the preparation method comprises the following steps: uniformly mixing the high-alumina bauxite and the silicon carbide, adding the boron nitride and the mesoporous silica, and uniformly stirring to obtain a mixture; uniformly mixing a binder and a lubricating dispersant to obtain a mixed solution, adding the mixed solution into the mixture, uniformly mixing, heating, pressing, molding, baking and drying to obtain the finished carbon brick. The ladle lining brick has good slag corrosion resistance and high temperature resistance, under the circulating high-temperature and low-temperature condition, the brick body is still not prone to being corroded by molten slag, the problems of cracking and stripping of the brick body are solved, and the service life of the ladle lining brick body is prolonged.
本申请涉及铝碳化硅碳砖技术领域，具体公开了一种抗渣侵蚀的铝碳化硅碳砖及其制备方法；一种抗渣侵蚀的铝碳化硅碳砖，包含以下的原料：高铝钒土60‑80份、碳化硅15‑20份、氮化硼2‑8份、介孔二氧化硅1‑4份、粘结剂3‑6份、润滑分散剂1‑2份；其制备方法为：高铝矾土、碳化硅混合均匀，添加氮化硼、介孔二氧化硅搅拌均匀，得到混合料；粘结剂和润滑分散剂混合均匀得到混合液，混合液添加到混合料中，混合均匀，经升温打压成型、烘烤、干燥后，得到成品碳砖；具有较好的抗渣侵蚀性、耐高温性，在循环高温低温的条件下，使砖体仍不易被熔渣侵蚀，阻止砖体出现开裂、剥落问题，延长铁水包内衬砖体的使用寿命。
