摘要： A steel melt is confined and subjected to a partial vacuum. A particulate additive is entrained by a neutral nonreactive carrier gas and introduced into the melt below the surface thereof at a depth such that the additive is immediately vaporized and rises toward the surface of the melt in the form of bubbles which react with components of the melt. With particulate calcium as the additive an injection depth 1500 mm, a temperature of approximately 1500.degree.C, and a vacuum of 20 Torr allows the sulfur content of a steel melt readily to be reduced below 0.005% by weight.
