  • Sulfur additive for molten steel and method for producing resulfurized steel
    Patent number: 11098384
    Abstract: A sulfur additive is added to molten steel. At that time, the yield of sulfur in the molten steel is stabilized and nozzle blockage at the time of continuous casting due to impurities is prevented. A sulfur additive used for molten steel which contains iron sulfide ore particles with a particle size of 5.0 to 37.5 mm in 85 mass % or more with respect to the total mass % of the sulfur additive is used to produce Al deoxidized resulfurized steel containing S: 0.012 to 0.100 mass %.
