| Abstract: | Studies were conducted on volatile rules of vacuum distillation of hot galvanized scrap to investigate the effects of distillation temperature and time, as well as vacuum degree on the volatile rate and the purity of volatile matter. The optimum technological conditions obtained from industrial experiment were as follows: at a temperature of 1 173 K, after 14 hours of distillation, with furnace pressure of 50～100 Pa, zinc metal with zinc content above 99.9% can be obtained with a direct recovery rate of 93.37%. |
