活泼金属熔融炉耐材探究 active metal furnace refractory layer research

对于高温下活泼金属熔融炉耐材衬，对传统耐火材料提出了新的要求，活泼金属或双氧型金属熔融液体以及强腐蚀型金属液体，传统的镁，铝，碳质耐火材料都不能在高温下满足他们的熔炼需求，在工业化要求长时间连续作业的要求下，无法满足满足长时间连续生产的负荷 。

故此，配合整体炉型以及工艺的再升级要求，探索通过多种高纯材料再复合，在不降低高纯材料的耐火性能的前提下，结合各个材料的优势，通过对特殊部位的强化处理，以及多层物理复合工艺，配合新炉型，在熔池内部找到高温溶液与耐火材料临界点解决对活泼金属，强腐蚀性金属溶液的工业化炉对耐火材料长寿的要求。

For active metal  melting furnace refractory lining at high temperature, put forward new requirements for traditional refractory materials, active metal  or hydrogen peroxide metal molten liquid and strong corrosive metal liquid, traditional magnesium, aluminum, carbon refractory can not meet their melting needs at high temperature, under the industrial requirements of long time continuous operation, cannot meet the long time continuous production load.

Therefore, with the overall furnace type and process upgrade requirements, explore through a variety of high purity material compound, without reducing the fire resistance of high purity material, combined with the advantages of each material, through strengthening processing of special parts, and multilayer physical composite process, with the new furnace type, in the tank find high temperature solution and refractory critical point for lively metal, strong corrosive metal solution of industrial furnace of refractory longevity requirements.
