铝尖晶石耐侵砖
Mafic alumina spinel bricks
铝尖晶石耐侵砖 是我公司开发的适用于冶金固体废物处理回转窑烧成带的新一代产品,该产品在高温抗渗透、抗侵蚀、抗应力强度方面的性能较以往产品有了大幅提升,较之前的炉龄普遍提高了1倍以上,目前该产品已得到用户的广泛认可。
Alumina spinel resistant bricks was developed by our company applies to the metallurgical solid waste with rotary kiln calcining zone of a new generation of products.the product in the hiah temperature permeability resistance.erosion resistance. resistance to stress intensitv in the oerformance of the products has improved than ever before and more before the furnace life is generally more than doubled,and now the products have been widely recognized by users.
