1. Excellent cycle rate of Si and C composite deoxidizer
2. High purity due to high content of Si and C (not less than 80%)
3. Excellent heating effect due to high carbon content
4. Shorten working hours
5. Easy to control carbon content
6. Improve the quality of molten steel, improve the quality of products, improve the new energy of products, reduce the amount of alloy added, reduce the cost of steelmaking, and increase economic benefits.
