Comparison Between Silicon Carbide And Ferrosilicon

The following are the advantages of using silicon carbide compared to ferrosilicon.

 

 

1. Higher silicon content: Silicon carbide has a higher silicon content, which enhances the reducibility of molten iron and is a more effective reducing agent than ferrosilicon.

 

2. Reduce energy consumption: The efficiency of reducing SiC to silicon is improved, thereby reducing energy consumption. The higher reaction rate and lower amount of SiC required to supplement the same amount of silicon reduce the time and energy required for this process.

 

3. Low energy consumption: Although SiC is a reducing agent with higher quality, the production of silicon carbide is simpler, requiring only silicon dioxide, petroleum coke and electricity. However, FeSi requires the processing of iron ore and coke and higher energy consumption.

 

4. Reducing emissions: Compared to FeSi, the production of SiC results in lower greenhouse gas emissions. The use of SiC also reduces the amount of waste generated during the production process.

 

 

5. Improve product quality: Due to the absence of common impurities in FeSi in silicon carbide, using SiC when increasing silicon content will produce higher quality products. Silicon carbide can also produce cleaner reducing agents, thereby reducing impurities in the final product.

 

In summary, compared to ferrosilicon, the use of silicon carbide has many advantages in increasing silicon content. SiC is a more effective reducing agent with higher silicon replenishment rate, lower energy consumption, and lower cost. It also produces higher quality products and reduces emissions, making it a more sustainable alternative to FeSi.
