Abstract

PURPOSE:The inexpensive desulfurizing material for molten iron which comprises compounding calcium carbonate to quicklime powder at the specific ratios and which is replaceable to calcium carbide. CONSTITUTION:When the desulfurizing material comprising compounding calcium carbonate at 7-15% to quicklime powder is charged into molten iron, a suitable amount of CO2 gas is produced to prevent agglomeration of quicklime, thereby providing the desulfurization effect equivalent to that of calcium carbide.
