Abstract
The investigation on the Zone-Refining of aluminium by high frequency induction heating have so far been much reported. But the investigation by Ni-Cr wire heating has not been reported so much, the author studied on the condition of Ni-Cr wire heating of the Zone-Refining of Al and measured the recrystallization temperature. With this measuring the author conjectured the degree of purification instead of the chemical analysis. Also, the effect of intermediate annealing temperature on the abnormal grain growth after the light tension work was studied.It was found out that the slowest speed (8mm/hr) gives a very good result in case of Ni-Cr wire heating and more purified aluminium needs higher temperature of the intermediate annealing to get the large grain size by the abnormal grain growth.
