Basic information of non-stick aluminum castables
This series of materials is a new type of material with low cement content and ultrafine powder combination based on high-purity mullite, andalusite and sillimanite. Due to the combination of high-purity raw materials and ultra-fine powder, this series of materials has high bulk density, high strength, and good thermal shock stability. Salt, etc.), can greatly reduce the wettability of aluminum and alloys and slag to refractory materials, and improve the corrosion resistance, erosion resistance, and non-sticking of aluminum refractory materials to aluminum liquid containing chemical components such as salt and flux. The slag and slag function prevents aluminum and alloys and slag from penetrating into the refractory material, prolonging the life of the furnace lining. Ideal for melting furnaces, static furnaces, launders, aluminum cladding linings.
