1. Improving the quality of molten steel: It can reduce the hydrogen and oxygen content in the steel, lower the degree of oxidation on the surface of the steel, thereby improving its corrosion resistance and reducing anisotropy.
2. Good insulation effect: It can form an insulation layer on the surface of the molten steel to prevent it from transferring heat to the air, achieving the goal of reducing the temperature of the molten steel and saving energy.
