Application of SiC refractory plate raw materials

Carboneto de silício has four main application areas: cerâmica funcional, advanced refractory materials, abrasives, e matérias-primas metalúrgicas.

⑴ As an abrasive, it can be used to make grinding tools, such as grinding wheels, oilstones, grinding heads, sand tiles, etc.
⑵ As a metallurgical deoxidizer and high-temperature resistant material.
⑶ High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.

Application of silicon carbide plate

Ceramics industry

Silicon carbide plates have a wide range of applications in the ceramic industry. They are often used to produce grinding wheels, ceramic coatings such as enamels and electrical insulators, daily ceramics, architectural ceramics, and glass and papermaking processes, including nozzles, nozzles, kiln furniture, and cyclone separator components.

Metallurgical Industry

More than 65% of large blast furnaces in the world use silicon carbide materials, extending the life of blast furnaces by up to 40%. These materials are widely used as furnace linings or crucibles when smelting aluminum, cobre, and zinc. Além disso, silicon nitride plates can be used to manufacture immersion thermocouple tips for measuring the temperature of steel in electric furnaces.

Indústria química

Na indústria química, ceramic heat exchangers are often used to recover waste heat from various furnaces by preheating gases or liquids. Silicon carbide refractory plates can be used as efficient heat exchanger materials with their excellent thermal properties and high-temperature strength. Silicon carbide has a thermal conductivity three times higher than steel, making it an ideal material for manufacturing thermocouple protection tubes for temperature measurements up to 1400°C.

Energy Industry

Carborundum plates have a wide range of applications as environmental heat exchangers. High-temperature purified coal gas is directly used for gas turbine power generation, significantly improving power generation efficiency and reducing harmful emissions.

Filtration System

Silicon carbide plates play an important role in high-performance, high-temperature particle control ceramic filtration systems. These systems not only promote the use of advanced fossil fuels but also have great application potential in other high-temperature industrial processes, waste incineration, e outros campos. Kerui Refractory Company will provide the best quality and service.
