UN PROCEDIMIENTO PARA FABRICAR ACERO POR AFINO DE UNA MASA PREDETERMINADA DE METAL FUNDIDO.

摘要

A process for making steel by refining a predetermined mass of molten metal having a composition containing at least carbon and iron comprising: injecting oxygen into such mass with a gaseous diluent at a first dilution ratio and calculating from the activity coefficient of each element in the mass a theoretical equilibrium partial pressure of carbon monoxide for the oxidation reaction of each element; calculating the absolute maximum partial pressure of carbon monoxide; selecting the lowest partial pressure and calculating a new metal analysis for the mass; changing the dilution ratio upon meeting a given criterion and repeating the process until the carbon level of the mass has dropped to a predetermined level.
