摘　　要：本次实验以烧结镁砂为主原料,加入铬绿微粉,从而制备出多种配方的镁铬质浇注料.通过对镁铬质浇注料和高铝质浇注料的性能检测,选取各自性能最佳的配方并制备出两个渣罐,然后进行抗渣性对比实验,对两种材质的耐火材料的抗渣侵蚀性进行研究.通过研究,探究出一种优质高效的耐火材料以提高镍铁合金炉炉衬的使用寿命.A variety of chromium-magnesium-containing casting materials for furnace lings were fabricated by adding chrome powder to magnesia-base refractory materials. The chromium-magnesium casting materials so fabricated, and the conventional high-aluminum one, were then examined to screen out the best compositions of the 2 casting materials from which specimens for final slag-resistance tests were prepared. A high-quality refractory casting material was then made, which could effectively enhance the service life of the linings of the ferreniekel-alloy smelting furnace.
