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.

Steel fiber reinforced refractory castable is mainly made of high quality bauxite clinker, brown corundum as aggregate and powder, adding aluminate cement, ultra-fine powder, heat-resistant stainless steel fiber, admixture, etc. Heat-resistant stainless steel fibers are introduced into the material to make the material have higher strength and toughness, thereby increasing the wear resistance and thermal shock stability of the material, thereby increasing the service life.
