Abstract
Se trata de un proceso de eliminación y recuperación del cinc contenido en la chatarra galvanizada compactada, que usualmente es aportada como materia prima para fusión en fundiciones y acerías, proceso en el cual el cinc se evapora y se separa del acero al calentarlo a una temperatura inferior en todo caso a la temperatura normal de vaporización del cinc (906 °C) MEDIANTE INDUCCION y bajo vacío (aproximadamente a 5 mbar), realizándose posteriormente una condensación de los vapores para la recuperación y revalorización económica del cinc, que resulta en estado sólido y de gran pureza. Dicho proceso se realiza previamente a que la chatarra galvanizada sea incorporada al proceso de fusión, todo ello para evitar el tratamiento de los polvos recogidos de los humos tras el proceso de fusión, como se realiza tradicionalmente y para evitar la salida de gases tóxicos al exterior.It is a process of elimination and recovery of zinc contained in compacted galvanized scrap, which is usually provided as raw material for melting in foundries and steelworks, a process in which zinc evaporates and separates from steel when heated to a temperature. in any case below the normal vaporization temperature of zinc (906 ° C) BY INDUCTION and under vacuum (approximately 5 mbar), subsequently condensing the vapors for recovery and economic revaluation of zinc, resulting in a solid state and of great purity. This process is carried out before the galvanized scrap is incorporated into the melting process, all to avoid the treatment of the dust collected from the fumes after the melting process, as is traditionally done and to prevent the outflow of toxic gases to the outside. .
