Application of fused magnesium lanthanum/cerium-based refractory material in smelting of rare earth steel ladle
The invention belongs to the technical field of refractory materials, and particularly relates to application of an electric smelting magnesium lanthanum/cerium-based refractory material in smelting of a rare earth steel ladle. According to the application of the fused magnesium lanthanum/cerium-based refractory material in smelting of the rare earth steel ladle, rare earth steel contains lanthanum and/or cerium, and the ladle refractory material comprises a furnace body and a slag line; the furnace body refractory material takes an electric smelting magnesium lanthanum/cerium-based refractory material and a binding agent as raw materials, and the slag line refractory material takes the electric smelting magnesium lanthanum/cerium-based refractory material, crystalline flake graphite, phenolic resin and an antioxidant as raw materials. The rare earth steel has high thermal shock resistance and high erosion resistance, and meanwhile, the erosion of the rare earth steel to the refractory material at the slag line part of the steel ladle in the smelting process can be effectively reduced. In addition, the yield of rare earth elements is also remarkably improved.
本发明属于耐火材料技术领域，具体涉及一种电熔镁镧/铈基耐火材料在冶炼稀土钢钢包中的应用。一种电熔镁镧/铈基耐火材料在冶炼稀土钢钢包中的应用，所述稀土钢含有镧和/或铈，钢包耐火材料包括炉体和渣线；所述炉体耐材以电熔镁镧/铈基耐火材料和结合剂为原料，所述渣线耐材以电熔镁镧/铈基耐火材料、鳞片石墨，酚醛树脂和抗氧化剂为原料，本发明的一种电熔镁镧/铈砂在冶炼稀土钢钢包耐火材料中的应用，不仅具有高抗热震性和高抗侵蚀性，同时可以有效减少稀土钢在冶炼过程中对钢包渣线部位耐火材料的侵蚀。此外，对于稀土元素的收得率也有显著提升。
