Abstract

PURPOSE: To obtain purified Al by adding B to molten Al contg. Ti, putting a cooling pipe in the molten Al, and feeding a cooling medium to the pipe while relatively rotating the pipe and the molten Al to crystallize Al on the surface of the pipe.
CONSTITUTION: To molten Al contg. Ti is added B is an amount making the atomic ratio to Ti 2W5. B is added as an Al-B mother alloy or a flux contg. B such as potassium borofluoride or sodium borofluoride. A cooling pipe is put in the molten Al, and by feeding a cooling medium to the pipe while relatively rotating the pipe and the molten Al, Al is crystallized on the surface of the pipe. The Al crystallized pipe is then separated from the residual molten Al and heated to melt the crystallized Al. Thus, purified Al is obtd.
