Refractory material prepared from waste refractory material and used for blast furnace tapping channel
The invention relates to the technical field of refractory materials, in particular to a blast furnace tapping channel refractory material adopting waste refractory materials, which comprises waste materials, an impurity removal agent, zirconium oxide, mixed powder for mixing the materials and a binding agent for the zirconium oxide, the waste materials comprise aluminum-magnesium brick crushed materials, brown aluminum oxide, silicon carbide, magnesium aluminate spinel, modified phenolic resin, aluminum-silicon gel powder, calcium aluminate cement, metal aluminum powder, silica powder and explosion-proof fibers. According to the preparation method, the pre-sintered material is subjected to activity treatment at the temperature lower than the sintering temperature, so that the pre-sintered material has thermal shock performance and compactness, and through analysis of a scanning electron microscope, crystal grains in a product are uniformly distributed in the product, so that the refractory material has the characteristic of stable crack propagation, and the compactness and thermal shock performance of the product are improved; and the refractory material for the blast furnace tapping channel, which adopts the waste refractory material, can reduce the cost of the refractory material, save mineral resources and reduce environmental pollution at the same time.
本发明涉及耐火材料技术领域，具体说的是一种采用废旧耐火材料的高炉出铁沟用耐火材料，包括：废旧材料、除杂剂、氧化锆、用于混合材料的混合粉和用于氧化锆的结合剂；所述废旧材料包括铝镁砖破碎料、棕刚玉、碳化硅、镁铝尖晶石、改性酚醛树脂、铝硅凝胶粉、铝酸钙水泥、金属铝粉、硅微粉和防爆纤维。本发明中，预烧制料经过低于烧制温度活性处理，使其具有热震性能和致密性，经过扫描电子显微镜分析，制品中的晶粒均匀分布在制品中，使得耐火材料具有稳定裂纹扩展的特征，使得产品的致密性和热震性能得到了提升，力学性能也得到了提升，采用废旧耐火材料的高炉出铁沟用耐火材料，能够降低耐火材料成本，同时节约了矿物资源，减少环境污染。
