EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

The technological knowledge of BOF process represents an important key to improve metallurgical results. In a challenging and competitive market, operational stability and innovation are necessary to achieve excellent quality and suitable costs. In order to study the combined blowing (top and bottom blow) through cold physical model, in similarity with thyssenkrupp 330 tons converter, visual inspection and colorimetry methods were used to define the jet penetration and the best TBM tuyeres configuration on the metal bath behavior, as the main objective in the present work.
