Corundum Mullite Castables
Corundum mullite refractory castable is an indefinite refractory material made of corundum and silicon carbide.
It has excellent wear resistance and high use temperature (1500℃) and is known for its simple construction process, short working period, and superior construction characteristics.
Its service life is significantly higher than other wear-resistant refractory materials and is widely used in electric power, metallurgy, steel, ceramics, and other industries.
PER Refractories produces refractory castables that are widely used in high-temperature industries such as steel, cement, and petrochemicals because of their excellent insulating and heat-resistant properties.
Product Use
Corundum mullite refractory castable material can be widely used in circulating fluidized bed combustion belts, cyclones, heat radiation material, and other parts using refractory materials.
This product is suitable for parts with serious wear and tear. This product is corundum and silicon carbide high-strength material so that the degree of wear and tear is greatly reduced.
This product is constructed by pouring, and it can also be made into prefabricated parts/prefabricated blocks, which is convenient and fast, thus shortening the construction period and saving money.
Composition of Corundum Mullite Castable
Corundum mullite castable is made of brown corundum, white corundum, red pillar stone, mullite, and high-quality bauxite as the main raw materials, with superfine powder refractory powder mixed by scientific formula ratio.
Corundum mullite refractory castables contain less mullite in the natural world. The mullite used in industry is synthesized artificially.
It has high purity, high density, good organization, low creep rate, low thermal expansion, good thermal shock resistance, and good resistance to chemical attack. It is widely used in refractory materials and other industries.
Corundum mullite castables are made with high-quality refractory raw materials and have good thermal shock resistance.
Characteristics of Corundum Mullite Refractory Castables
It has the common advantages of corundum refractory castable and mullite castable. Under high temperatures, part of the matrix reacts in situ to produce a mullite phase, which improves the high-temperature thermal strength and thermal shock stability of the castable lining.
It has high high-temperature compressive strength, good resistance to thermal shock and structural spalling, good high-temperature volume stability and thermal shock resistance, high load softening temperature, low creep rate at high temperatures, and good chemical corrosion resistance.
Corundum Mullite Castables Application Scenarios
Corundum mullite castables can be used in the petrochemical industry for tubular heating furnaces, light diesel fuel, ethane cracking furnace lining, normal decompression furnaces, sulfur recovery devices, steam boilers, turtle mesh heat insulation layer, two-ware barrels, and pipe heat insulation monolayer, another industrial furnace door, fire hole, observation hole door lining, large power station boiler anti-wear lining, gasification furnace, circulating fluidized bed boiler lining and cement rotary kiln coal injection tube and another high-temperature kiln lining.
