Details Introduction

According to the different parts of the aluminum melting furnace, the corresponding refractory materials are selected. The load on the furnace roof is small, requiring good integrity and peeling resistance. The furnace wall that does not contact the aluminum liquid must bear a certain load. Low cement castables with alumina content above 60% are usually used in the furnace roof and furnace walls. The bottom part of the furnace that contacts the aluminum liquid requires that the porosity of the refractory material is low, and it does not wet with the aluminum solution and does not react. The furnace bottom and the molten pool are the key to determine the life of the whole furnace. Using high quality high bauxite, corundum, silicon carbide as the main raw materials, control the free quartz and mullite phase in the material, improve the chemical stability of the material; Add anti-aluminum liquid wetting agent to improve the anti-aluminum liquid wettability of the material; Add ultra-fine powder and use high-efficiency water reducing agent to reduce the amount of water added, thereby reducing the porosity of the product and increasing the density.

Lightweight insulation castable is made of lightweight aggregate, synthetic microporous aggregate and fine bauxite powder as the main raw materials, combined with aluminate cement, plus a number of additives. The product has the characteristics of low density, high strength, low thermal conductivity, good thermal insulation performance, can be the whole casting or prefabricated molding, is the ideal product of high temperature furnace wall insulation.
