Abstract

PURPOSE:To improve desulfurization performance and achieve the reduction in the cost of molten iron desulfurization by adding the specific metal fluorides in the desulfurizer for molten iron composed primarily of calcium oxide. CONSTITUTION:The metal fluorides selected from MgF2, LiF, NaF, KF and Na2SiF6 are further added to calcium oxide or the one compounded with 5-20%, based on this, of carbon contents, e.g., graphite, coke, etc., whereby the desulfurizer for molten iron is obtained. The amount of addition of the metal fluorides is 0.1- 10% based on the calcium oxide.
