ABSTRACT:
An apparatus and method to form a metal containing degenerate dendrites are disclosed. Molten metal is cooled in a receiving means and agitated by rotating blades connected to a rotating shaft. Solid metal, such as dendrites, deposited on inner wall portions of the receiving means are removed by suitable means, such as a scraping blade, in operable combination with the rotating blades. The so produced metal can be cast by conventional metal casting processes.
