Types of Refractory Castable
Refractory castables are unshaped refractory materials that are commonly used in the construction of furnace linings, kilns, and other high-temperature processing equipment. They are made by combining refractory aggregates, binders, and additives with water, resulting in a dense, hard, and chemically resistant material that can withstand extreme temperatures.
Low Cement Castables
Low cement castables (LCC) are a type of refractory castable that are made with a low amount of cement content, typically less than 5%. The low cement content results in a highly dense and strong material that has excellent mechanical and thermal shock resistance.
LCCs are ideal for use in high-temperature environments, such as the linings of rotary kilns, boilers, at mga incinerators. They can withstand temperatures up to 1800°C and are highly resistant to alkalis and acids.
Self-Flowing Castables
Self-flowing castables (SFC) are a type of castable refractory that are designed to be highly fluid and able to flow into complex shapes and areas. They are made with a special binder system that allows for excellent flowability and self-leveling properties.
SFCs are often used in applications where complex shapes or designs are required, such as in furnace linings or chimney linings. They are also ideal for use in areas where manual installation is difficult or impossible.
Insulating Castables
Insulating castables (IC) are a type of refractory castable that are designed to have a low thermal conductivity, resulting in excellent insulation properties. They are made with lightweight aggregates and high-purity binders, resulting in a material that is both strong and lightweight.
ICs are ideal for use in applications where thermal insulation is required, such as in the linings of furnace walls, roofs, and floors. They are also commonly used in the construction of backup insulation for other types of refractory linings.
High-Alumina Castables
High-alumina castables (HAC) are a type of castable refractory that are made with high-purity alumina aggregates and binders. They have a high alumina content, typically above 80%, resulting in a material that is highly resistant to abrasion, corrosion, and erosion.
HACs are ideal for use in applications where high mechanical strength and chemical resistance are required, such as in the linings of blast furnaces, ladles, at mga incinerators. They can withstand temperatures up to 1800°C and are highly resistant to alkalis and acids.
Mullite Castables
Mullite castables (MC) are a type of castable refractory that are made with mullite-based aggregates and binders. Mullite is a high-temperature ceramic material that has excellent thermal shock resistance and chemical resistance.
MCs are ideal for use in applications where high thermal shock resistance and chemical resistance are required, such as in the linings of boilers, incinerators, and kilns. They can withstand temperatures up to 1800°C and are highly resistant to alkalis and acids.
Silicon Carbide Castables
Silicon carbide castables (SCC) are a type of refractory castable that are made with silicon carbide-based aggregates and binders. Silicon carbide is a high-temperature ceramic material that has excellent thermal conductivity, abrasion resistance, and chemical resistance.
SCCs are ideal for use in applications where high thermal conductivity and abrasion resistance are required, such as in the linings of furnaces, kilns, at mga incinerators. They can withstand temperatures up to 1800°C and are highly resistant to alkalis and acids.
Phosphate-Bonded Castables
Phosphate-bonded castables (PBC) are a type of refractory castable that are made with a phosphate-based binder system. The binder system results in a material that has excellent chemical resistance and high strength at high temperatures.
PBCs are ideal for use in applications where high chemical resistance and strength are required, such as in the linings of kilns, incinerators, and boilers. They can withstand temperatures up to 1500°C and are highly resistant to alkalis and acids.
Kaya nga, It Is Crucial To Choose The Right Refractory Castables
In conclusion, there are several types of refractory castables available, each with unique properties and advantages that make them suitable for specific applications.
Low cement castables are highly resistant to thermal shock and ideal for high-temperature environments, while self-flowing castables are ideal for complex shapes and areas.
Insulating castables are excellent for thermal insulation, while high-alumina castables are highly resistant to abrasion, corrosion, and erosion.
Mullite castables have excellent thermal shock and chemical resistance, while silicon carbide castables have high thermal conductivity and abrasion resistance. Phosphate-bonded castables have excellent chemical resistance and high strength at high temperatures.
When selecting a refractory castable, it is important to consider the specific requirements of the application, such as temperature range, chemical exposure, mechanical stress, and insulation properties.
With the right selection, refractory castables can provide long-lasting and reliable protection for high-temperature processing equipment.
Technical Points of Construction of Refractory Castables
Among the main technical points of the construction of refractory castable include.
1. The ratio of refractory castables should not be changed arbitrarily in the construction, and water or other materials should not be added arbitrarily in the mixed refractory castables.
2. The template for pouring should have sufficient strength and rigidity, and the size of the mold should be accurate, and prevent deformation during the construction process.
3. The joints of the form work should be tight and no slurry should be leaked, and anti-adhesive measures should be taken for the formwork.
4. The surface of heat-insulating masonry in contact with the castable should take waterproof measures.
5. The pouring of refractory castables should be carried out continuously, and the second layer of castables should be poured before the first layer of castables condenses, and the interval exceeding the condensing time should be handled according to the requirements of construction joints. Construction joints should be left on the center line of the same row of anchored bricks.
6. After construction, the refractory castable should be maintained according to the design method, and should not be subject to external force or vibration during maintenance.
