Abstract
The desulfurization agent for molten iron is made up of 70 to 95% commercial calcium carbide, 5 to 25% silicon dioxide, 0 to 10% of a metal oxide; and 0 to 5% calcium fluoride. The metal oxides are iron oxides and manganese oxides. The desulfurizing agent has been found to reduce the amount of calcium carbide in the resulting slag.
