Abstract
The invention relates to technology desulfuration of liquid cast iron. A method comprises the tapping of cast iron from blast furnace and its separation from blast-furnace slag,of solid high-alkaline ladle slag of fraction of 3-10 mm in quantity no less 5 kg/t of cast iron and blowing up in cast iron of desulfurizer. Technical result: decreasing of consumption of desulfurizer due to support of desulfurated ability of high-alkaline ladle slag.
