80 high aluminum brick introduction:
The content of Al2O3 is higher than 80%, which is called super-grade high aluminum brick.In China, according to the content of Al2O3 in high aluminum brick is usually divided into four grades: super grade, first grade, second grade and third grade.Extra - grade high - alumina brick is a kind of neutral refractory material with alumina content above 80%.It is formed and calcined from alumina or other raw materials with high alumina content.High thermal stability, refractoriness in more than 1770.Good slag resistance, used for lining of electric steel-making furnaces, glass furnaces and cement rotary furnaces.
Characteristic and Advantages:
High - charge soft and low - creep high - alumina brick is a kind of high - grade refractory material made of super - grade alumina, fused corundum and fused mullite.The product has the advantages of high load softening temperature, small creep at high temperature, strong corrosion resistance, good thermal shock stability and so on. It is suitable for large and medium high temperature kilns, chemical industry, electric power industry and other high energy consuming industries.It is mainly used for lining of blast furnace, hot blast furnace, boiler, reflection furnace and rotary kiln.In addition, high aluminum brick price should be higher than clay brick, so the place that can satisfy the requirement with clay brick need not use high aluminum brick.
