Resumen
En este trabajo se realizó un estudio de la mezcla propuesta por Álvarez Corcho, la cual utiliza un 20 % de silicato de sodio para aglomerar el polvo de acería, al realizarse su procesamiento aluminotérmico se obtuvieron concentrados de cinc y plomo además de obtener una aleación de hierro y una escoria de características abrasivas. Se realizaron coladas en las que se evaluó la influencia del suministro de un flujo de aire sobre los resultados del proceso. Los resultados se analizaron a partir de los datos preliminares de un balance de masa. Se realiza una propuesta de diseño de un filtro de mangas con el objetivo de mejorar la eficiencia de captación de los polvos y finalmente se realizó valoración económica del proceso.
In this work a study of the mixture proposed by Álvarez Corcho was carried out, which uses 20% of sodium silicate to agglomerate the steelworks powder. When the aluminothermic processing was carried out, zinc and lead concentrates were obtained in addition to obtaining an alloy of iron and a slag with abrasive characteristics. Castings were made in which the influence of the supply of an air flow on the results of the process was evaluated. The results were analyzed from the preliminary data of a mass balance. A proposal for the design of a bag filter was made in order to improve the efficiency of the dust collection and finally an economic evaluation of the process was carried out.
