Steel ladle tank edge brick and preparation method thereof
The invention belongs to the technical field of refractory materials for metallurgy, and particularly relates to a steel ladle tank edge brick and a preparation method thereof. The ladle tank edge brick is formed by mixing regenerated magnesium-chromium materials and regenerated aluminum-carbon materials with different particle sizes under the action of a binding agent, the magnesium-chromium materials formed by crushing waste magnesium-chromium bricks are adopted as main raw materials, existing magnesia, graphite, waste magnesium carbon and the like are replaced, and the production cost is greatly reduced; meanwhile, risks such as material mixing are reduced, burdening of various materials is reduced, and the production efficiency is improved; and meanwhile, the used magnesite-chrome brick is reused, so that the circular economy is realized, and the material consumption is reduced. And on the other hand, the regenerated magnesium-chromium material is adopted as the main raw material and has good slag resistance, and meanwhile, the regenerated aluminum-carbon material is adopted for compounding, so that the oxidation resistance is improved, and the medium-temperature and high-temperature use strength of the tank edge brick is improved.
本发明属于冶金用耐火材料技术领域，具体涉及一种钢包罐沿砖及其制备方法。所述钢包罐沿砖由不同粒径的再生镁铬质料和再生铝碳质料在结合剂的作用混合而成，采用废镁铬砖破碎成的镁铬质料作为主要原料，替代了现有的镁砂和石墨及废镁碳等，大大降低了生产成本；同时减少混料等风险，减少了多种物料的配料，生产效率得到提升；同时将用后的镁铬砖进行再次利用，循环经济，降低了材料消耗。另一方面，采用再生镁铬质料作为主要原料，具有很好的抗渣性，同时采用再生铝碳质料复合，抗氧化性得到提升，提升了罐沿砖的中温和高温使用的强度。
