Influence of the Addition of a Reducing Mixture Slag and Duration of Treatment on the Desulphurisation and Deoxidation Efficiency

Abstract

Within the researches made, the establishment of the processing with synthetic slag decreasing possibilities, of the sulphur and oxygen contents, from the steel made in electric arc ovens, of 100 t ladle capacity oven (LF) - (EBT) type, was taken into account. For the formation of the synthetic slag, reducing mixing made of lime, fluorine, bauxite and aluminum slag. The experiments we performed consisted in adding the waste mechanical mixture at the bottom of the ladle, its melting leading to the formation of synthetic slag. The obtained data was processed in the EXCEL program, obtaining correlation equations between the desulphuration, deoxidation and the addition of a reducing mixture, respectively the treatment duration.
