Corundum castable is using fused white corundum or alumina as refractory aggregate, adding a variety of superfine powder and calcium aluminate cement as binder, to produced to unshaped refractory material by proportion mixing.The alumina content of corundum castable is more than 85%.
Characteristics of Corundum Castable：
Good thermal shock stability, spalling resistance, wear resistance and acid medium corrosion resistance.
Application of Corundum Castable：
It is mainly used in combustion chamber, separator and flue of circulating fluidized bed boiler.
Technical Parameters of Corundum Castable:
|Al2O3 ，% ≥||90||80|
|Bulk Density ，g/cm3 ≥||2.85||2.85|
|Thermal shock stability 1100℃≥||80||70|
|Bending Strength，110℃×3h Mpa ≥||13||10|
|Compressive Strength，110℃×3h Mpa ≥||110||100|
High alumina refractory Castables is categorized into the unshaped monolithic refractory.
Ceramic wear-resistant castable is made of high-strength wear-resistant aggregate and ultra-fine powder. The selected refractory raw materials have super wear resistance. Generally, the common refractory raw materials with wear resistance include silicon carbide, brown corundum, steel fiber, etc. the fusion of refractory aggregate and powder makes the ceramic wear-resistant material have erosion resistance and can resist the erosion of molten slag and gas according to the principle of the closest accumulation.
Refractory mortar produced from fine grained refractory aggregate, refractory powder, binder and other additives and used for building and bonding the refractory bricks, and also repairing of furnace lining, which is mainly used in glass furnaces, hot blast furnaces, coke ovens, soaking furnaces, heat exchangers, boilers and other industrial kilns.
