Furnace Lining Nonstick Aluminum Refractory Castable with Corrosion Resistance and Al2O3-SiO2 Chemical Composition

Product Introduction:

Non-stick aluminum castable is a professional refractory material used in the aluminum processing industry. This product combines the characteristics of organic and inorganic binders and adds some new composite refractory materials that are insoluble in aluminum to effectively control the corrosion of refractory materials from molten aluminum.

Application:
It is mainly used in furnace walls, furnace bottoms, degassing boxes, launders, exits, front boxes and holding furnaces. This product effectively solves the problem caused by the reaction of refractory materials for the aluminum industry and liquid aluminum.

Features:
1. High bulk density.
2. High strength.
3. Good corrosion resistance to molten aluminum.
