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 material, control the free quartz and mullite phase in the material, improve the chemical stability of the material, add anti-aluminum liquid wetting agent, improve the anti-aluminum liquid wettability of the material, add ultra-fine powder and water reducing agent, reduce the amount of water, thereby reducing the porosity of the product, improve the density.

Non-stick aluminum castable is specifically for aluminum alloy melting castable. The use of high quality bauxite, corundum aggregate and fine powder, adding a variety of additives with ultra-fine powder combination made. high quality raw materials and combination system make the castable more dense, and good compactness prevents the penetration of aluminum liquid. In the process of use, the wetting angle of the material to the aluminum liquid is improved by additives, and the adhesion rate of the aluminum liquid is reduced. At the same time in the aluminum smelting process does not produce aluminum ash, no nodulation, so as to avoid impurities into the aluminum alloy affect the quality of aluminum alloy.
