A method of Separating Alkali Metals and Alkaline Earth Metals contaminants from a Cylindrical mass of Molten Aluminum contained within a container

摘要

Improvements in a method for Separating Alkaline Earth Metal contaminants from a cast Aluminum Cylindrical Mass contained within a recipiente.consistentes: establish the Whirlwind eccentrically relative to the geometric Axis of the container; treat with Molten Metal AlF3 or NAF.AlF3 Powder, which has a low weight ratio of NAF AlF3; use a Cylindrical container with a minimum internal diameter D; fill the bowl with the Molten Metal Mass to a height h, and to shape the impeller having a diameter D and height H Palette, for Ma such that the ratio d / d is between 0.1 and 0.6 and the ratio H / H is between 0.1 and 0.7.Being measured (d) and (d) in the plane of rotation of the impeller (H) and (H) along the Axis of rotation of the impeller.
