稀土合金在国民经济中有很重要的作用,目前我国供不应求,炉衬材料是影响产量的重要原因之一。 采用反射炉冶炼稀土合金,成本低,电耗少,产量大。但现有耐火材料抵抗不了含氟炉渣的严重侵蚀,使反射炉的合理使用受到限制。 根据国家需要,在有关单位的组织下,包钢有色一厂、二冶建研所及北京钢铁学院 Rare earth alloys in the national economy has a very important role, at present, our country is in short supply, lining material is one of the important reasons affecting the yield. Refined furnace smelting rare earth alloy, low cost, low power consumption, large output. However, the existing refractories can not resist the serious erosion of the fluorine-containing slag, so that the rational use of the refire furnace is limited. According to the needs of the country, under the organization of the relevant units, Baotou Nonferrous First Plant, Erye Research Institute and Beijing Iron and Steel Institute
