ARISTIZABAL SIERRA, Ricardo Emilio. Simulation of melting process and net diagrams for the Cupola Furnace of the University of Antioquia. Rev.fac.ing.univ. Antioquia [online]. 2006, n.37, pp.176-187. ISSN 0120-6230.

The best values of the adjustable parameters of the AFS Cupola Model for modeling the cupola furnace of University ofAntioquia were obtained form experimental data. Generalized net diagrams were simulated and developed for this unit. Profiles of temperature, gas phase concentrations and carbon content in the metal were obtained. The net diagrams include the basic generalized net diagram, with ambient temperature blasting and without oxygen enrichment. In addition, the behavior of production and temperature of metal at the tap hole under preheated blasting and oxygen enrichment was analyzed. This analysis allowed us to demonstrate the advantages of working under those conditions. The value of the parameters used to adjust the software was in agreement with their inherent physical meaning. Moreover, the software predictions (E.G, profiles and the diagram) agree with the experimental observations. The possibility to build net diagramsfor other cupola with the same procedure highlighted.
