Abstract

Molten metal baths e.g. cast iron, are refined by blowing with pure oxygen fed through the inner of two coaxial pipes under the metal surface. The outer pipe conveys protective fluid either in the form of a liquid, finely divided solid or a combination of both. Spec. the protective fluid is a natural or synthetic liquid hydrocarbon, pulverised solid fuel particles or alternatively a gas. A reduction in the specific volume of the reaction vessels is achieved.
