Abstract

Method and apparatus for controlling the refining of a metal bath by pneumatic insufflation in a refining vessel in which the amount of carbon that escapes from it per unit of time, in gaseous form, is measured continuously and a curve is established called "decarburization curve" which indicates the flow of carbon leaving the bath as a function of a parameter linked to the initial point of the bath carbon, characterized in that an extrapolation of said decarburization curve is established during the course of the refinement , it is deduced in advance the amount of carbon present in the bath at any time and the amount of oxygen needed to reach the percentage of carbon predefined beforehand is insufflated.
