名称:镁铬砖
镁铬砖一般是由烧结镁砂和耐火级铬矿为原料生产的,耐火晶粒间为硅酸盐结合,国内所说的镁铬砖,一般是指烧成的普通镁铬砖,简称镁铬砖。
镁铬砖的耐火度大于2000℃,荷重软化温度一般在1550℃以上,高温体积稳定性好,耐急冷急热性比镁砖强。
It is made with sintered magnesia and refractory level chrome ore as raw space between refractory grains is bonded with domestic so called magnesite-chrome brick refers to sintered normal magnesite-chrome brick.
The refractoriness of magnesite-chrome brick is more than 2000℃,The refractories under load is above1550℃. good steady volume in high temperature,the performance of meeting sudden cold and sudden hot is better than magnesite brick.
