The use of silicon carbide
1. Application in non-ferrous metal smelting industry
With its high temperature, high strength, good thermal conductivity and impact resistance it can be used for high-temperature indirect heating materials, such as distillation furnace, distillation furnace trays, aluminum electrolysis tank, copper melting furnace linings, zinc furnace arc plate and thermocouple protection tubes.
2. The application in iron and steel industry
With its anti-corrosion, thermal shock resistance, good thermal conductivity and other characteristics, it can be used for large blast furnace lining to increase service life.
3. The applications in metallurgical beneficiation industry
The hardness of silicon carbide is only next to diamond. Silicon carbide has a strong wear resistance, is the ideal material for making wear-resistant pipe, impeller, pump room, hydrocyclone and the ore lining of ore bucket.
4. The application in building, ceramics and wheel industry
With its thermal conductivity, heat radiation, high heat intensity characteristics, it can be used for making kiln sheet, which can not only reduce the kiln capacity, but also increase the installed furnace capacity and product quality and shorten the production cycle.
5. The application in energy saving
It can be used for making heat exchanger for its good thermal conductivity and thermal stability. The fuel consumption can be reduced by 20% and it saves fuel by 35%, thus it increases the productivity by 20-30%, its wear-resistant is 6-7 times the normal wear-resistant materials especially in the usage in mining pipeline.
