There are many types of refractory castables produced by castable manufacturers, mainly including the following:

1. High-aluminum castable: High-aluminum castable uses alumina as its main component and has high refractoriness, slag resistance, and thermal shock resistance. It is widely used in high-temperature furnaces and hearths in steel, non-ferrous metals, chemicals, and other industries.

2. Steel fiber reinforced castable: Steel fiber reinforced castable is based on ordinary castable, adding steel fiber to enhance its thermal shock resistance, wear resistance, and slag resistance. They are mainly used in furnaces, furnace bottoms, and other parts of steel, metallurgy, petrochemical, and other industries.

3. Mullite castable: Mullite castable is mainly composed of mullite and has good wear resistance, refractory resistance, and slag resistance. It is often used in key parts such as steel-making furnaces and converters in steel, metallurgy, and other industries.

4. Silicon carbide castable: Silicon carbide castable uses silicon carbide as the main component and has excellent wear, slag, and thermal shock resistance. It is widely used in high-temperature furnaces, hearths, and other parts of non-ferrous metals, chemicals, ceramics, and other industries.

5. Low-cement castables: refer to castables with a low cement content. The cement content is generally about 5%, and some are even reduced to 1% to 2%. Low-cement castables use ultra-fine particles not exceeding 1 μm, which significantly improves their thermal shock resistance, slag resistance, and erosion resistance.

6. Wear-resistant refractory castables: The main components of wear-resistant refractory castables include refractory aggregates, powders, additives, and binders. Wear-resistant refractory castable is a kind of unshaped refractory material widely used in metallurgy, petrochemicals, building materials, electric power, and other industries. This material has the advantages of high-temperature resistance, wear resistance, and corrosion resistance. It is used to repair and protect the lining of high-temperature equipment such as furnaces and boilers to increase the service life of the equipment.

7. Ladle castable: Ladle castable is made of high-quality high-alumina bauxite clinker and silicon carbide as the main materials, with pure aluminate cement binder, dispersant, anti-shrinkage agent, coagulant, explosion-proof fiber, etc. The unshaped refractory castable composed of admixtures is also called aluminum silicon carbide castable due to its good use effect in the working layer of the molten iron ladle.

8. Lightweight heat-insulating refractory castable: Lightweight heat-insulating refractory castable is a refractory castable with lightweight, high strength, and excellent heat insulation properties. It mainly comprises lightweight aggregates (such as perlite, vermiculite, etc.), high-temperature stable materials, binders, and additives. It is widely used in various high-temperature industrial equipment, such as industrial furnaces, heat treatment furnaces, steel furnaces, glass melting furnaces, etc., to improve the energy efficiency of the equipment and reduce energy consumption.

9. Corundum castable: Due to its excellent performance, corundum castable has become an ideal choice for key parts of thermal kilns. Corundum castables are characterized by high strength, high softening temperature under load, and good slag resistance. The general use temperature is 1500~1800℃.

In short, castable manufacturers produce a wide range of refractory castables, with specially targeted products for different industries and application scenarios. These castables not only ensure the safe and stable operation of the equipment but also improve production efficiency and product quality. Through continuous research development and innovation, castable manufacturers are committed to providing more advanced, efficient, and environmentally friendly refractory material solutions for various industries.
