HOE 89/H 010 Agent and process for desulfurizing molten metals 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, gasevolving substances and magnesium components are fluidized together and the fluidized product is introduced into the melt.
