Aluminum electrolysis cell cathode repairing material
The invention discloses an aluminum electrolysis cell cathode repairing material, which is prepared by the following steps: on the basis of analyzing and researching the advantages and disadvantages of the existing furnace repairing material, selecting a mixed material with high density, erosion resistance and strong binding force with a cathode, and taking fused white corundum, cryolite and aluminum fluoride as raw materials; the characteristics of high density, high electrolyte corrosion resistance and no pollution to molten aluminum of the fused white corundum and the softening and bonding characteristics of cryolite and aluminum fluoride at the aluminum electrolysis temperature are fully utilized, perfect combination of the repairing material and the cathode is achieved, the defects of traditional magnesia brick repairing are overcome, meanwhile, the repairing effect is improved, and the service life of the repairing material is prolonged. And the fettling frequency of workers is greatly reduced, and a foundation is laid for safe operation of the electrolytic cell.
本发明公开了一种铝电解槽阴极修补料，本发明是在分析研究现有补炉材料优缺点的基础上，选择采用了高密度、耐侵蚀以及与阴极结合力较强的混合材质，本发明以电熔白刚玉、冰晶石、氟化铝为原料，充分利用了电熔白刚玉密度高、耐电解质侵蚀性能强、不污染铝液的特性以及冰晶石、氟化铝在铝电解温度下软化粘接特性，实现了修补料与阴极的完美结合，本发明不仅克服了传统的镁砂镁砖补炉存在的缺陷，同时提升了修补效果，大大降低了工人补炉频次，为电解槽安全运行奠定了基础。
