镁铬砖是Ao'an耐磨. ao'an耐火材料的旗舰产品，已经生产了50多年的镁铬砖，并且是中国此类产品的先锋
The magnesia chrome brick has excellent slag corrosion resistance, high temperature overheating damage resistance, vacuum damage resistance, oxidation resistance, reduction resistance and abrasion resistance. Magnesia chrome bricks are widely used in key parts of metal smelting furnaces, especially the working linings of smelting furnaces that use vacuum, or change of acid and alkali of smelting slag, or strong氧化气氛，例如各种高质量的钢制炉炉（Rh或Dh真空脱气炉，Vod Ladle真空脱气炉，Aod Aod Ard Argon氧气精炼炉，超高的电动电炉，.），{{3} （闪光灯炉，转换器，阳极炉，kaldor炉等.）.
盐下盐后，可以在盐浸出后的物理和化学性能和服务性能大大改善.，产品的孔隙率降低了约5 . 0％，散装密度增加了约0.05g/cm3，并且兼容的强度增加了约30mmpa。
根据所使用的不同原材料，将镁铬砖系列产品分为三类：重新组合的镁铬砖（FMK），直接键合镁铬砖（DMK）和半重组的镁含量
结合镁铬砖，融合的镁铬合成砂被用作主要原材料，并在超高温度下发射{.，它具有极好的氧化性还原性能，过度过热的损伤性，耐磨性，耐磨性和耐侵蚀性，耐受性损坏稳定性，尤其是超级损坏的能力，尤其是超级损坏的势力{face face {face facection { practice that, under the vacuum smelting environment, or under the strong oxidizing atmosphere, or under the strong scouring of superheat liquid, or under the corrosive service environment of strong alkaline slag liquid and slag liquid with alkalinity change, the combined magnesia chrome brick is currently a furnace lining material with long life and high cost performance. It is widely used in vacuum smelting furnace (such as RH真空脱气装置，VOD真空脱气钢包），氩氧精炼炉（例如AOD炼油器），超高的电力炉，非有效的金属冶炼炉和其他具有严重工作条件的关键部位，例如易受伤害
