Abstract

1500188 Controlling oxygen steelmaking VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE-ALPINE MONTAN A G 13 Jan 1975 [15 Jan 1974] 1333/75 Heading C7D A top-blown oxygen steelmaking process in which refining is carried through to completion is statically controlled to obtain desired final values of Mn and P in the steel by initially calculating the amount and type of lime to be used according to predetermined relationships. Refining is then carried out according to a pre-set blowing schedule with no further control action. The process is based on estimation of the proportion of charged lime which will be in solution in the slag by the end of refining (a parameter which may be varied by modification of the grain size or the amount of fluxing additions) and on the oxidizing capacity of the slag as measured by its iron oxide content. The relationships on which control is based are determined for a particular installation by analysis of the data from previous heats.
