Estimación de la viscosidad de escorias fayaliticas utilizando el modelo de cálculo kv y el método experimental del plano inclinado* V. Bazán**, Ch. Goñi***, L. Castellá****, E. Brandaleze****, L. F. Verdeja***** y R. Parra** ResumenLa viscosidad de las escorias representa una de las variables más relevantes de la mayoría de los procesos metalúrgicos y cinética de las operaciones de refino, dado que es uno de los factores determinantes de la eficiencia en las reacciones entre metal y escoria, tanto como escoria-refractario. En las últimas décadas, los modelos matemáticos de diferentes procesos metalúrgicos han establecido métodos para predecir la viscosidad de mezclas de óxidos fundidos a altas temperaturas, en función de la composición química. El modelo Kv desarrollado por Toguri, basado en los datos ofrecidos por Johasen et. al. y Winterhager, ha propuesto la utilización de un índice (Kv) similar a la relación usada en la industria del acero como el índice de basicidad. Se presentan, en este trabajo, valores de la viscosidad determinados en forma experimental mediante la técnica de plano inclinado. Palabras claveViscosidad. Escorias fayalíticas. Modelo Kv. Método del plano inclinado. Determination of viscosity of fayalite slags for kv model and measurements by means of inclined plane AbstractThe viscosity of the slags represents one of the most relevant variables of most of the processes metallurgical and kinetics of the refine operations, since it is one of the decisive factors of the efficiency in the reactions between metal and slag, as much as slag -refractory. In the last decades, the mathematical models of different metallurgical processes have established methods to predict viscosity of mixtures of oxides fused to high temperatures in function of the chemical composition. The model developed by Toguri, based on the data reported by Johasen and Winterhager et al has proposed the Kv model. The used index it is similar to the relationship used in the steel industry like the basicity index. It is presented in this work values determined of viscosity in experimental form by means of the technique of inclined plane.
