High Alumina Refractory Castable for Power Generation Industry electric furnace and kiln maintenance
Product name : High alumina refractory castable
Specifications :HY-JZL-2
Introduction of castables :
Castable, also known as refractory castable, is a granular and powdery material made of refractory materials and a certain amount of binder. It has high fluidity and is an amorphous refractory material formed by casting. Castable is a kind of amorphous refractory material which is most commonly consumed and used at present. It is used to construct all structures of various heating furnace linings and can be used in smelting furnaces. Aluminate cement castables can be widely used in various heating furnaces and other thermal equipment without slag and acid-base corrosion. In areas where the working temperature is high due to the corrosion of molten iron, molten steel and slag, such as steel outlet tank, steel drum, blast furnace body and iron outlet ditch, castables made of high-quality granular and powder materials with high alumina content and good sintering can be used, which are combined with low calcium and pure high alumina cement.
Corundum refractory castable is made of fused corundum as the main raw material, combined with a variety of super subdivision and high efficiency additives. The secondary characteristics are high strength, good volume stability, excellent corrosion resistance, and are not affected by reducing gases such as H2 and CO. Products are generally applicable to circulating fluidized bed boiler, metallurgy, petrochemical, thermal power and other industries.
Wear-resistant castable is a kind of cement-based composite one-component dry powder mortar, which is prepared by industrial production of high-strength cement, mineral admixture, high-strength aggregate and anti-cracking and wear-resistant agent. The lining anti-wear layer of slag flushing ditch, ore trough, coal unloading trough, hopper, silo and the anti-wear layer of water conservancy and hydropower, unloading hopper, which are used in metallurgy, coal, thermal power, chemical industry, cement and other industries, play the role of maintaining the bottom concrete ( or steel silo ).
Steel fiber castable is prepared by using special grade bauxite clinker as aggregate, high quality bauxite clinker and corundum fine powder as matrix, ultrafine powder and other composite materials as binder and additive, and stainless steel heat-resistant fiber. In addition to the conventional low-temperature wear-resistant function, the product has participated in a certain number of heat-resistant stainless steel fibers in its ingredients to avoid.
