We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of Corundum castable
Corundum wear resistant castable has a higher wear resistance and higher compressive strength, the fire resistance can reach 1900 . This product is an amorphous refractory material which is mixed and modulated in proportion with fused white corundum or alumina as refractory aggregate, adding various ultrafine powders and calcium aluminate cement binder.
Features of Corundum castable
Corundum wear resistant castable has good overall stability, good furnace lining integrity, long service life, practical construction and can be shaped arbitrarily.
Application of Corundum castable
Corundum wear resistant castable applies to a variety of metallurgical industrial furnaces, chemical industrial furnaces, waste incinerators and boilers in CFB.
