Refractory castable is a mixture of refractory aggregates, powders, and binders. After adding water or other liquids, it is suitable for construction using pouring and vibration methods. It is used to construct industrial furnace linings and can also be pre made into prefabricated components with specified shapes and sizes.It has fire resistance and high temperature resistance, with low fire resistance temperatures reaching around 600 ºC and high resistance temperatures reaching around 1800 ºC;
Characteristics of refractory castables
1.High compressive strength and high stability at high temperature;
2. High compressive strength;
3. Strong resistance to lag erosion and tension;
4. Good resistance to cold and heat or objective environmental changes;
5. Can resist chemical corrosion of acid slug or solution;
6. Compared with the production of refractory bricks, it does not need high temperature sintering and has low energy consumption;
7. The product has diverse performance and can be made into wear-resistant and fire-resistant, lightweight insulation, corrosion and peeling resistant, non stick aluminum, high-strength, acid resistant, alkali resistant, etc. according to usage.
Refractory Castable Classification
1. According to their chemical properties, they are divided into acid resistant castables, neutral castables, and alkali resistant castables.
2. According to density, it can be divided into lightweight castable and heavy castable.
3. According to the refractory materials, they are mainly divided into different refractory materials such as clay castable, high alumina castable, siliceous castable, mullite castable, corundum castable, magnesium castable, silicon carbide castable, etc.
4. According to their characteristics, they are divided into: high-strength wear-resistant castables, high-temperature resistant castables, low cement castables, steel fiber castables, acid and heat resistant castables, slag resistance and wear-resistant castables, heat-resistant steel fiber reinforced castables, and other refractory castables with unique characteristics.
5.According to its usage, it can be divided into various industrial kiln castables such as steel rolling heating furnace castables,blast furnace runner castables, metal mixer castables, ladle castables, boiler specific castables, furnace door castables, cement kiln castables, etc.
The classification of different dimensions, the types of refractory castables, and the applicable industrial kiln environment are also different, so suitable refractory castables should beselected.
Refractory Castable Application
Refractory castables can be directly used as lining for boilers, kilns, and furnaces, or prefabricated into refractory prefabricated blocks for masonry in industrial furnaces. They can also be used in kilns and thermal equipment in the petroleum, chemical, building materials, ceramics, glass, steel, power, and mechanical industries.
