Other fields:

It can also be used to manufacture heat-resistant foam glass, ceramic fillers and aggregates, etc., and can also be used as a reinforcing phase of composite materials to improve the strength, hardness and wear resistance of materials.

1. Metallurgical Industry: Efficient Deoxidation and Improved Molten Steel Quality

A large steel plant used silicon carbide as a deoxidizer in its converter steelmaking process. The oxygen content in the molten steel was reduced by 30%, and the absorption rate of silicon and carbon increased to 92%. By replacing some recarburizers, the cost per ton of steel was reduced by 12 yuan. Molten steel purity was improved, inclusion content was reduced by 40%, and ingot quality was significantly improved, making it particularly suitable for the production of high-strength and alloy steels.

2. Refractory Materials: Extending the Life of High-Temperature Equipment

A power plant's pneumatic ash handling system elbows were lined with wear-resistant linings made of 88% silicon carbide with a size of 1-10mm. This extended the elbow life from three months with conventional manganese steel to three years, reducing wear by 80%. The material remained stable even in 800°C ash-slag conditions, reducing maintenance downtime and saving over 500,000 yuan in annual replacement costs.

3. Environmental Protection: Corrosion and Wear-Resistant Solutions

A thermal power plant's wet desulfurization system uses nitrogen-connected silicon carbide (N-SiC) nozzles (containing 88% silicon carbide). These nozzles have a lifespan of 60,000 hours in a strong acidic and alkaline environment with a pH of 2-12, ten times that of traditional stainless steel nozzles. Spray uniformity has improved by 30%, desulfurization efficiency has increased from 90% to 95%, and slurry waste has been reduced by 15%.

4. Wear-Resistant Coating and Equipment Repair

A chemical plant underwent on-site repair of severely worn elbows and pump casings on its slurry pipelines using a silicon carbide wear-resistant coating (containing 88% silicon carbide granules). The repair reduced wear by 90% and extended equipment life by five times. The coating, with a thickness of only 1-2 mm, does not affect pipeline flow, reducing the repair cycle to one-third that of traditional replacement methods.

5. Specialty Ceramics and New Energy

A lithium battery production line utilizes corrosion-resistant components in the electrolyte delivery piping and agitator. Silicon carbide ceramic bushings are resistant to 30% sulfuric acid corrosion, with a weight loss of less than 0.01g/year. This prevents metal contamination of the electrolyte, improves battery consistency, and increases product yield from 92% to 98%.
