Description
Alumina Silica Fireclay Brick is formed by forming and calcining alumina or other materials with high alumina content. High thermal stability, refractoriness above 1770℃. Good slag resistance is mainly used for the lining of blast furnaces, hot blast furnaces, electric furnace roofs, blast furnaces, reverberatory furnaces, and rotary kilns.
Alumina silica fire brick belong to the group of alumina-silica refractory products. This kind of products are applied widely in iron, steel, glass, and nonferrous metals industries under high temperatures.
ZHENAN provides all kinds of alumina silica brick bricks in low price. Alumina silica fire bricks plays an important role in various high temperature industries.
Major Categories:
♦Semi Siliceous Products (Al2O3≤30%)
♦Fire Clay Products (30%≤Al2O3≤48%)
♦High Alumina Products (Al2O3≥48%)
Different raw materials and volumes of component determine the kind of products.
