Abstract

1511740 Controlling oxygen steelmaking CENTRE DE RECHERCHES METALLURGIQUES-CENTRUM VOOR RESEARCH IN DE METALLURGIE 24 Nov 1975 37925/77 Divided out of 1511739 Heading C7D The process of refining iron in a converter by blowing with oxygen is controlled by monitoring the intensity of emitted sound having a frequency < 20 Hz and detecting the instant at which the intensity shows a sudden and marked decrease. A controlled further amount of oxygen is then injected to produce either a desired phosphorus content in the steel or iron oxide content in the slag, that amount of oxygen being obtained from predetermined relationships.
