Preparation method of fused magnesium lanthanum/cerium sand refractory raw material
The invention belongs to the field of refractory materials, and particularly relates to a preparation method of an electric smelting magnesium lanthanum/cerium sand refractory raw material. The high-performance electric smelting magnesium lanthanum/cerium sand refractory raw material is obtained through three steps of mixing, pelletizing and electric smelting. The high-quality refractory raw material with high purity, high cleanliness and large crystallinity is produced and prepared by adopting an electric melting mode and fully utilizing the advantages of lanthanum oxide and cerium oxide for improving the crystal lattice structure of magnesium oxide, purifying the crystal boundary and inducing the growth of magnesium oxide crystal grains. The refractory raw material produced by the invention not only can provide a refractory material for pure smelting of rare earth steel, but also can realize large-scale industrial application of lanthanum-cerium light rare earth.
本发明属于耐火材料领域，具体涉及一种电熔镁镧/铈砂耐火原料的制备方法。通过混合、造球和电熔三步获得高性能的电熔镁镧/铈砂耐火原料。本发明采用电熔方式，充分利用氧化镧和氧化铈改善氧化镁晶格结构、净化晶界及诱导氧化镁晶粒生长的优势，生产制备高纯度、高洁净度和大结晶的优质耐火原料。本发明所生产的耐火原料不仅可为稀土钢的纯净化冶炼提供耐火材料，同时亦可实现镧铈轻稀土的大规模工业化应用。
