Abstract

The desulfurization of hot metal by the injection of fluidized lime in the 300-t casting ladles of the oxygen-converter shop at OAO Alchevskii Metallurgicheskii Kombinat is investigated. Analysis of the results shows that, in the deep desulfurization of hot metal with an initial sulfur content of 0.020–0.030% by a mixture of granulated magnesium and fluidized lime, the lime injected with magnesium into the hot metal has no significant effect. Measures are proposed to reduce the desulfurization costs and the losses of hot metal with the ladle slag.
