The desulfurization agent for molten iron is made up of 95 to 70% commercial calcium carbide, 30 to 5% calcium aluminate slag, and 10 to 0% of a metal oxide. The calcium aluminate slag is made up of 65 to 50% calcium oxide, 35 to 25% aluminum oxide, and 12 to 3% calcium fluoride. The metal oxides are ferric oxide, manganomanganic oxide and ferrosoferric oxide. The desulfurizing agent has been found to reduce the amount of calcium carbide in the resulting slag. |
