Abstract: An agent for desulfurizing molten metals, in particular molten iron, comprises a CaC2/CaO crystal blend with a maximum of 62% by weight of CaC2, gas-evolving substances and 0 to 44% by weight of metallic magnesium as the components. For desulfurizing molten metals, in particular molten iron, using this agent, either the mixture comprising both the CaC2/CaO crystal blend and gas-evolving substances, and the magnesium, are fluidized separately and the two fluidized products are combined immediately before they enter the melt, or the CaC2/CaO crystal blend, gas-evolving substances and magnesium components are fluidized together and the fluidized product is introduced into the melt.

Abstract: Mixture for desulfurizing metal melts based on calcium carbide, calcium oxide, alkaline earth metal carbonates, aluminum oxide, chemically unbonded carbon and alkali metal carbonates, if any. The desulfurizing mixture contains 0.3-4.5 wgt % calcium fluoride as an additional constituent and is produced by grinding the individual constituents jointly in a mill over a period of 3-30 minutes.
