Refractory castable is currently the most widely used production and a monolithic refractories. Mainly used to build a variety of furnace lining and so the overall structure. Some high-quality varieties can also be used for smelting furnaces. Aluminate cement refractory castable can be used in a variety of furnaces and other non-residue, no-acid erosion of the thermal device. In the affected iron, steel and slag erosion and high temperature parts, such as a steel tank, ladle and blast furnace body, iron ditch, etc., can be used by low calcium and pure alumina cement bound by the containing high alumina refractory sintering good quality granular and powdered materials made of castable. Another example is the phosphates are widely used in refractory castable both furnace and heating the metal soaking furnace, coke oven can also be used for cement kilns direct contact with materials of the site. In metallurgical furnaces and other containers with slag and molten metal in direct contact with some of the sites, the use of high-quality phosphate castable repair also have good results. In some of the work is not very high temperature and high wear resistance of parts required, the use of phosphate refractory castable is more appropriate. If the selection is made corundum refractory castable refractory material, the use of general Jie good results in a reducing atmosphere. High-quality high-purity synthetic raw materials are formulated refractory castable basis of new technologies, but also the efficiency of the production of basic monolithic refractories. Such as tabular alumina, dense corundum, white corundum, corundum mullite, magnesium aluminate spinel, spherical high purity magnesia and bauxite and so on. In addition, the use of high-quality bauxite and other raw materials, after the sintering process ingredients or fused, made of corundum, white corundum, corundum-white, and aluminum-magnesium spinel, bauxite-based synthetic material collectively, through the appropriate process, its performance, can be partially substituted alumina-based synthetic materials, are widely used.
