Non-wettability to molten slag.

Application:

Electric arc furnaces;
Lining of steel ladles;
Basic oxygen furnaces.

Specification:

鎂碳磚

以方鎂石為主要礦物組分的耐火材料製品。按照原料組成的不同,可分為:鎂碳磚用製磚鎂砂製成的鎂磚,加入少量特級礬土或工業氧化鋁的鎂鋁磚,加入一定量石墨粉的鎂碳磚,用質量較差的高矽鎂砂製成的鎂碳磚。與其他耐火磚相比,鎂製磚的耐火度較高,可達2000℃以上,有較高的荷重軟化溫度,較大的高溫機械強度,還有很好的抵抗含有氧化鐵和氧化鈣的堿性熔渣的化學侵蝕的性能。

製品中氧化鎂含量為85%左右,氧化鋁含量為5%~10%,以方鎂石為主晶相、鎂鋁尖晶石為次晶相(作為主要結合相)的堿性耐火材料,顯氣孔率一般為3%~8%,熱膨脹系數為10.6*10-6/℃,熱抗震性相比其他材料要好。由於基質中分部有熔點較高的鎂鋁尖晶石,其高溫強度較高,荷重軟化溫度在1580℃以上,抗渣性也較好。一般以優質電熔鎂砂為粒裝料,加入一定比例配合的鎂砂同生礬土或輕燒礬土熟料或工業氧化鋁組成的細粉,經混煉、成型和燒成而製得。

產品優勢:良好的抗熱震性;耐渣性高;耐高溫性能好;抗渣滲透能力強;熔渣不潤濕性。

應用:  電弧爐; 鋼包內襯;  吹氧轉爐。
