電熔鎂鋁尖晶石是以優(yōu)質(zhì)工業(yè)氧化鋁和高純輕燒鎂為主要原料，在電弧爐中經(jīng)2000℃以上高溫熔融而成，具有體積密度大、熱穩(wěn)定性好、抗渣性能好、熱震穩(wěn)定性好、抗侵蝕能力強、抗腐蝕能力強、耐高溫等特點，廣泛應(yīng)用于中高檔定型和不定型耐火材料、鋼鐵冶煉、水泥回轉(zhuǎn)窯和玻璃工業(yè)窯爐上等。
Electrocast alumina-magnesia spinel is composed synthesis of industrial alumina and high purity light burning magnesium as the main raw materials, refined in the electric arc furnace with more than 2000 ℃ high temperature. It is a large volume density, good thermal stability, good slag resistance, good thermal shock stability, perfect anti-erosion ability, high corrosion resistance, high temperature resistance and other characteristics. I t is widely used in high-grade stereotypes and unshaped refractories, steel smelting, cement rotary kiln and glass industrial kiln and so on.
