Zirconia-Corundum Casting Castables

Chrome corundum castables (also called zircon corundum castables, zirconia corundum castables, or chromium corundum castables) belong to the series of composite corundum castables. is made of a-Al2O3, Zr2O3, and zirconium corundum clinker as materials, zircon corundum castables are produced by mixing, molding, drying, and sintering at high temperatures in a shuttle kiln. Zircon corundum castables are a new type of top-grade unshaped refractory material. Refractory castables can be used in a 2000-degree high-temperature kiln, the effect is obvious. Refractory chrome corundum castables are more than double the service life of traditional corundum castables.

Application of Zirconia-Corundum Casting Castables

1. Refractory chrome corundum castables are used in various high-temperature furnaces such as carbon black reactors, coal water slurry gasifiers, incinerators, smelting furnaces, steelmaking furnaces, and glass drawing furnaces.

2. Chrome corundum refractory castables are used in carbon black reactors, iron alloy furnaces, and coal water slurry gasifiers, the effect is very significant.

3. Refractory chrome corundum castables should be used as the lining material for various kilns such as boilers, blast furnaces hot blast stoves, heating furnaces, and ceramic kilns.

4. The melting furnace mainly uses ultra-high temperature zircon corundum brick or zircon corundum castables as the lining.

5. Refractory chrome corundum castables application in the carbon black plant carbon black reaction furnace, petrochemical kiln, heating furnace, garbage incinerator, non-ferrous metal smelting furnace, and iron hook material.
