Corundum Mullite Brick

Product Description:
Fused white corundum and high-purity fused mullite are used as the main raw materials, which are fired at high temperature after high-pressure molding.
Advantages:
high temperature resistance, small change in reburning line, good thermal shock resistance.
Application:
1. Glass fiber kiln and other glass kiln superstructure, channel, forming parts
2. Corundum brick can be used as auxiliary material and insulation material, high temperature kiln and ceramic glaze kiln lining
3. High purity and low silicon corundum brick is mainly used in petroleum and chemical gasifier, gasifier, etc
4.Glass kiln small furnace, feeding channel, channel and other parts, as well as furnace bottom and hearth of ironmaking blast furnace
