Abstract

Steel is de-phosphorized and de-sulphurized by pouring the molten steel into a receptacle, a mixture of one or more alkaline carbonates and an oxide, such as barium dioxide, which is energetically oxidizing with respect to the phosphorus being introduced into the jet of metal while the latter is being poured, the mixture evolving gases or vapours in a quantity sufficient to produce a violent agitation and seething. To prevent the cooling of the steel during the reaction, the mixture may also contain a reducing agent or exothermically acting mixture containing reducing agents such as an alumino-thermic or silico-thermic mixture. Specifications 14909/97, [Class 72], and 400,593 are referred to.
