Abstract
La presente invención se refiere a un proceso de colada semicontinua de aleaciones de zinc-aluminio-cobre para obtener barras circulares de estructura dendrítica fina, cuyo proceso comprende los pasos de: fundir una aleación previamente preparada en base de zinc-aluminio-cobre, en una relación de 21 a 23 por ciento de aluminio, 0.5 por ciento de cobre y el resto de zinc de temperaturas comprendidas de 480 a 600 C., enseguida hacer fluir la aleación fundida por gravedad hacia un contenedor alimentador a temperaturas similares a las de fusión y luego dicho material fundido hacia una lingotera de molde de forma deseada, caracterizado porque en la etapa de moldeo la interfase líquido-sólido presenta altos gradientes de temperatura comprendidas de 80 a 120 C/cm, que permiten obtener una estructura granular fina.The present invention refers to a semi-continuous casting process of zinc-aluminum-copper alloys to obtain circular bars with a fine dendritic structure, the process comprising the steps of: melting a previously prepared zinc-aluminum-copper based alloy, in a ratio of 21 to 23 percent aluminum, 0.5 percent copper, and the rest of zinc at temperatures ranging from 480 to 600 C., then flow the molten alloy by gravity into a feeder container at melting-like temperatures and then said molten material towards a mold ingot mold of the desired shape, characterized in that in the molding stage the liquid-solid interface presents high temperature gradients ranging from 80 to 120 C / cm, which allow obtaining a fine granular structure.
