Steel ladle lining ceramic welding material and preparation method and application thereof
The invention relates to the technical field of refractory materials, and particularly discloses a steel ladle lining ceramic welding material and a preparation method and application thereof. The ceramic welding material for the steel ladle lining comprises the following raw materials in parts by weight: 20-80 parts of Al2O3-MgO-CaO series particles, 20-80 parts of fused white corundum fine powder, 2-10 parts of fused magnesia, 10-20 parts of defective spinel micro powder and 2-20 parts of a ceramic binding agent, wherein the ceramic binding agent comprises 1-20 parts of pure calcium aluminate cement and 1-20 parts of aluminum oxide micro powder. The steel ladle lining ceramic welding material can be used for the surface of an old steel ladle lining, and has the advantages that the old steel ladle lining does not need to be dismantled, the service life of the old steel ladle is further prolonged, and generation of industrial waste is reduced.
本申请涉及耐火材料的技术领域，具体公开了一种钢包内衬陶瓷焊接材料及其制备方法和应用。钢包内衬陶瓷焊接材料包括以下重量份数的原料：Al2O3‑MgO‑CaO系颗粒20‑80份、电熔白刚玉细粉20‑80份、电熔镁砂2‑10份、缺陷尖晶石微粉10‑20份和陶瓷结合剂2‑20份，所述陶瓷结合剂包括纯铝酸钙水泥1‑20份，氧化铝微粉1‑20份。本申请的钢包内衬陶瓷焊接材料可用于钢包旧内衬表面，其具有不需要将钢包旧内衬进行拆除，进一步延长了旧钢包的使用寿命，减少了工业废弃物产生的优点。
