ABSTRACT:
An exothermic, reducing and basic ladle desulfurizing mix, and method for its use, which minimizes the temperature drop encounterd by the molten steel tapped from the furnace. The mix is comprised essentially of finely-divided particulate iron and/or manganese oxide, aluminum with minor magnesium and/or calcium alloying additions, and burnt lime. The need for other fluxing agents such as fluorspar is minimized or eliminated.
