The difference between refractory castable and refractory concrete

Refractory castable is a kind of granular and powdered refractory materials made of refractory mixture, adding a certain amount of binder and water together.Refractory castable has high fluidity, suitable for castable construction method, unshaped refractory material without heating can be hardened.The aggregate, powder, binder, additive composition, water or other liquid materials. In general use site casting, casting and tamping vibration method, and also can be made into the preform.
The main types of refractory castables are porosity, binder and aggregate:
1.According to the distribution of porosity of refractory castable, the two kinds of heat insulation refractory materials are made of dense refractory castable and porosity of not less than 45%;
2.According to the binding agent has a combination of water, chemical bonding, cohesion and refractory castable:
1)The combination of water and hard material at room temperature hardening and hardening by hydration, the main varieties of Portland cement, ordinary calcium aluminate cement, pure calcium aluminate cement, fused pure calcium aluminate cement castables;2)The chemical combination of the castable at room temperature generally by the addition of hardening agent to form a chemical reaction to harden, the main varieties are water glass, aluminum sulfate, phosphate castable, etc.;3) the agglomeration of the aggregate is hardened by sintering during the calcination process, and the main varieties are made of clay castable
Is a kind of refractory castable unshaped refractory materials production and is currently the most widely used. Mainly used for building heating furnace lining whole structure pressure in metallurgy, petroleum, chemical industry, building materials, electric power, machinery and industrial furnaces and heating equipment, heavy meals, high quality products can also be used for smelting furnace, the normal temperature strength of refractory castable generally have higher, can be made of prefabricated pieces installed in the kiln site.
Refractory concrete refers to the ramming construction method, and hardened in the heating effect is higher than the ambient temperature of unshaped refractory materials. Due to the refractory aggregate, has certain gradation of powder, binder, additive water or other liquid after mixing together. According to the material from the clay, high alumina, magnesia, Baiyun stone, zirconium and silicon carbide carbon refractory ramming material.
Refractory concrete with silicon carbide, graphite, calcined anthracite as raw material, adding a variety of fine powder additives, bulk material fused cement or composite resin as binder. To fill the gap or stack cooling equipment and masonry masonry filler. The leveling layer with ramming material and chemical stability, resistance to erosion. Abrasion resistance, spalling resistance, thermal shock resistance, are widely used in metallurgy, building materials, nonferrous metal smelting, chemical industry, machinery and other manufacturing industries!
Acidic, neutral and alkaline refractory concretewidely used in intermediate frequency coreless furnace core induction furnace, as if furnace ramming mass used for melting of cast iron, ductile iron, forging cast iron, vermicular cast iron and cast iron melting alloy, carbon steel, alloy steel, high manganese steel, tool steel, heat-resistant steel stainless steel, aluminum and its alloy melting, melting, copper, brass, copper and bronze and copper alloy etc.
