Model of Mixed Control for Carbon and Silicon in a Steel Converter.

Abstract

The removal of carbon in a steel converter has been studied under Gas-Liquid reaction considerations; diffusion and reaction parameters were determined and control regimes tested. Improvementof the prediction of C results in the end of the blowing process can be obtained considering the variation of factors during the process. This is also obtained by introducing the Si-removal in the simulation obtaining the C and Si evolution. Application to control is discussed in relation with the use of a slag reaction model.
