Good Slag Resistance Alumina Refractory Bricks 65% - 75% Al2o3 Content
The first-grade high-alumina brick (the aluminum content is not less than 75% refractory brick) is formed by pressing and calcining a high-quality raw material such as high-quality bauxite and alumina. The high-aluminum brick has a refractoriness of over 1790 °C. The load softening temperature is above 1510 °C, the thermal shock stability is good, and the slag resistance is good. It is mainly used for ladle furnace, masonry blast furnace (furnace, belly), hot blast stove (upper), electric furnace cover (top) Blast furnace, reverberatory furnace, rotary kiln lining etc...
We bring forth high quality High Alumina Bricks, which is manufactured to meet the requirements of neutral refractoriness where safe working temperature is more than 1300 degree centigrade. We offer high Alumina Bricks in different specifications as per customer requirements.
