Silicon carbide castable is a kind of unshaped refractory material with silicon carbide (SiC) as the main component. Silicon Carbide has excellent anti-wear, anti-oxidation and anti-corrosion properties, which makes Silicon Carbide castables have excellent stability and durability in high temperature, high pressure and corrosive environments.
Silicon carbide low cement castable is a kind of unshaped refractory material. It adopts refractory raw materials such as bauxite, brown corundum, silicon carbide, etc., and is formulated by applying ultra-fine powder technology and high dispersion technology. Silicon carbide low cement castable is characterized by low cement content, high strength after firing, and no decrease in strength at medium temperature.
Silicon carbide low cement castables have better construction fluidity, volume stability and certain wear resistance.
Silicon carbide low-cement castables can withstand extremely high temperatures, making them ideal for use in high-temperature industrial applications.
The low cement content and the use of silicon carbide as the main aggregate material give the castable excellent thermal shock resistance, preventing cracking and other damage during rapid temperature changes.
Silicon carbide low-cement castables are highly resistant to abrasion and erosion, making them ideal for use in applications where refractory linings are exposed to abrasive materials or high velocity air flow.
Silicon Carbide Low Cement Castable is also highly resistant to chemical attack, making it suitable for use in environments where it may be exposed to corrosive materials or gases.
The use of Silicon Carbide as the primary aggregate material gives this castable superior strength and durability to withstand the stresses of high temperature applications for extended periods of time.
Silicon Carbide low cement castables can be easily poured or cast in place, allowing for fast and efficient installation of refractory linings in a variety of applications.
Silicon carbide low cement castables are commonly used for walls, floors and roofs of industrial furnaces and have excellent resistance to high temperatures and thermal shock.
Silicon Carbide Low Cement Castable is used for lining combustion chambers and other high-temperature areas of incinerators, where it can withstand the corrosive and abrasive effects of waste materials.
Silicon Carbide Low Cement Castable can be used for the lining of boilers and other high temperature equipment in power plants, providing excellent resistance to thermal shock and abrasion.
Silicon Carbide Low Cement Castable can also be used for repair and patching of catalytic cracking furnaces, gasification furnaces and other high temperature chemical equipment.
Silicon Carbide Low Cement Castable is used in the iron and steel industry for patching and repairing high temperature equipment such as steel furnaces, iron furnaces, ladles and so on.
