It is a castable refractory material made of granular and powdered materials, and added a certain amount of binder composition and water together. It has a high flowability Gravity corundum castable with casting methods suitable construction, and without heating can be hardened monolithic refractories. The refractory aggregate, powder, binder, additives, water or other liquid material. Typically use the site to casting, vibration or tamping pouring molding methods can also be made using prefabricated parts. 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 soaking furnace heating metal in Hainan Gravity corundum castable, also be used for coke ovens, cement kilns in 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. Condensation hardening mechanism without cement castable binding mechanism for binding mechanism cohesion Yunnan Gravity corundum castable, depending on the added deflocculant (dispersing agent), first make castable or ultrafine particles occurs uniformly dispersed or glue the role of the casting material has a certain fluidity (or thixotropic), after the shock molding, and then rely on the original gel was added delayed action so castable coagulate and harden. Gelling agent is an electrolyte compounds, dissolved in water can be dissociated with rubber surface chargeability opposite counter ion species. When the particles adsorbed counter ions to achieve "isoelectric point" particles will occur unifying role, then it hardens through drying effect, so there is no cement castable hardening process is slow. Performance by combining sol oxide ultrafine or no cement castable physical and chemical properties of low cement and ultra low cement castable similar. But because of such impurities castable low Chongqing Gravity corundum castable, within the material less eutectic phase, which refractoriness, corrosion resistance and high-temperature structural strength are superior to low cement and ultra low cement castable. Such material is easily formed by sintering ceramic bond, its strength with increasing heat treatment temperature is gradually increased by the temperature, high temperature strength after heat treatment higher than after drying. Typical Si (). Free ultrafine combined high alumina cement castable physical and chemical properties are shown in Table.
