以钒铁渣、菱镁矿为主要原料,采用共磨、机压成形、高温烧成的生产工艺,生产出了主晶相为刚玉、尖晶石,体积密度大于3.0 g/cm3,吸水率小于1.5%,耐火度大于1 790℃的人工合成耐火原料,可替代高铝矾土、烧成尖晶石等耐火原料用于不烧砖、浇注料等产品中,实现工业固体废弃物的二次资源化及高附加值利用。
Ferrochromium slag and magnesite are taken as main raw materials to produce corundum and spinel whose main crystal phase is corundum and bulk density of more than 3.0 g / cm3 by using the production process of co-grinding, machine press forming and high-temperature firing, and the water absorption Less than 1.5%, refractoriness greater than 1790 ℃ synthetic refractory raw materials, high alumina bauxite can be replaced, firing spinel and other refractory raw materials for non-burning brick, castables and other products to achieve industrial solid waste two Secondary resources and high value-added utilization.
