Microtextural aspects of the chemical corrosion in Pierce-Smith converters (PSC)
Microtextural studies are often the basis for projects proposing improvements in the quality of refractory coatings that come
into contact with aggressive molten material. The material used for this analysis either comes from laboratory-level corrosion
tests or from furnace walls and linings that have come to the end of their working cycle.
This article aims to evaluate the reach of the chemical wear mechanism with a microtextural study of samples that have been
in industrial use. However, other wear mechanisms should be taken into consideration; acting in parallel they can be even
more important quantitatively than the chemical wear itself which results from the microtextural analysis of the samples.Peer reviewe
Aplicación del MDN al estudio de la corrosión de los convertidores Peirce - Smith
The Nodal Wear Model (NWM) constitutes a tool of applicable work study the processes of differential corrosion in the Peirce – Smith convertor (PSC) with the purpose of reaching significant improvements in duration and productivity of the several alternatives that one could utilize of the coating. For the application of the NWM to CPS is necessary of the knowledge the mechanisms of existent waste and the definition of the corrosion equations. With the NWM the outputs of corrosion in the tuyere zone of CPS are interpreted.<br><br>El Modelo de Desgaste Nodal (MDN) constituye una herramienta de trabajo aplicable al estudio de los procesos de corrosión diferencial en los convertidores Peirce - Smith (CPS) con el propósito de alcanzar mejoras significativas en duración y productividad de las diferentes alternativas que se puedan manejar del revestimiento. La aplicación del MDN al CPS precisa del conocimiento de los mecanismos de desgaste existentes y la definición de las ecuaciones de corrosión. Con el MDN se interpretan los resultados de corrosión en la zona de toberas del CPS

Los materiales empleados en este trabajo proceden de las paredes de hornos que están en la fase final de su vida útil. El trabajo intenta asociar el mecanismo de corrosión química existente con las modificaciones microestructurales encontradas en piezas utilizadas en planta. No obstante, debería considerarse que existen otros mecanismos de corrosión, que actuando en conjunción con los arriba descritos podrían ser más relevantes desde el punto de vista cuantitativo que la corrosión química detectada en los análisis micorestructurales de las muestras
