1. Silicon-carbon alloy is cheaper than ferrosilicon.
2. The silicon content is the same as ferrosilicon, and the carbon content is also high, which can significantly increase the temperature and increase the carbon content.
3. The content of harmful elements such as sulfur and phosphorus is extremely low.
