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 materials.the space between refractory grains is bonded with silicate.the 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.
