Zinc Removing from Aluminum Alloy by Vacuum Distillation

Abstract:

This paper summarizes the fundamental regularities and characteristics of vacuum distillation of aluminum alloy. It includes the vapor pressure values of aluminum alloy, the possibility and extent of distilling separation of the alloy, the proper temperature and time of distillation. With the temperature higher than 750°C，the distillation time longer than 30min，the content of zinc in the residue can be less than 0.3%．In this paper, the use of vacuum distillation resolved the difficulties of removing zinc from aluminum alloy, which is friendly to the environment and will not cause secondary pollution.. The theoretical analyses are in correspondence with the experimental data closely.
