Application and Characteristics of Silicon Carbide Bricks

2023-06-17 18:03:16

Silicon carbide bricks are one of the silicon carbide refractories. Silicon carbide bricks use silicon carbide as the main raw material. High-purity silicon carbide powder and high-activity silicon carbide are differentially mixed, and after grouting molding, they are vacuum sintered at high temperatures. High-grade refractory bricks for recrystallization.

The main content of silicon carbide bricks is SiC, with a content of 72%-99%. Due to the different bonding methods of silicon carbide bricks, the industries and thermal equipment used are also different. Different bonding methods can be divided into clay bonding, sialon bonding, alumina bonding, self-bonding, high aluminum bonding, silicon nitride bonding, and so on. What are the uses of silicon carbide bricks? Where is the main application?

Silicon carbide bricks are made of silicon carbide as the raw material. Silicon carbide, also known as emery, is made of quartz sand, coke, wood chips, and other raw materials through high-temperature smelting in an electric furnace. Silicon carbide is often used to make advanced refractory materials due to its stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance.

Silicon carbide bricks use the characteristics of silicon carbide, such as corrosion resistance, high-temperature resistance, high strength, good thermal conductivity, and impact resistance, to process and manufacture smelting high-temperature furnace linings, and are used in various high-temperature thermal equipment.

Application and Characteristics of Silicon Carbide Bricks

Application of silicon carbide brick
Due to different combination methods, silicon carbide bricks have slightly different uses. The main purpose of silicon carbide bricks is as the lining of thermal equipment, and different specifications of silicon carbide products can be processed according to the use of thermal equipment using different combinations. , such as silicon carbide plates, silicon carbide rings, etc.

Silicon carbide brick application
In the metallurgical industry, silicon carbide bricks are mainly used in aluminum melting furnaces for aluminum alloy smelting, secondary tuyere bricks in blast furnaces, etc.; in the power industry, they are mainly used in boilers as the nozzles of boiler combustion chambers; Applied to waste incinerators.
