Tabular corundum castable
Tabular Corundum Castable
Tabular corundum castable is high grade monolithic refractory which is composed of tabular corundum aggregate, fines and high alumina binder. Based on different applications, different kinds of ingredients can be added into tabular corundum castable to enhance its thermal, chemical and mechanical performances. For example, chrome corundum castable which has high refractoriness can be applied in carbon black furnace, coal gasifier lining. zirconia corundum castable which has excellent glass corrosion resistance is suitable for glass kiln. Composite corundum castable with specific composition can be used for various industrial kilns and furnaces such as cement rotary kiln, nonferrous metal smelting furnace, steel industry and so on.
Tabular Corundum Castable Property
High mechanical strength, good abrasion resistance.
Excellent thermal shock resistance, creep resistance.
High refractoriness, good high temperature volume stability.
Excellent Slag corrosion resistance, chemical corrosion resistance.
Convenient for construction, maintenance and patching.
