Metal forming.

摘要

Metal forming process and apparatus are described.

The process comprises directing a stream (4) of atomised droplets of molten metal onto a chill surface (5) such that the metal is partially solidified to form a slurry of solidified metal suspended in liquid metal. The slurry is then collected (for example, in a casting mould 7) and then cast or otherwise formed before solidification is complete. It is particularly preferred that the stream of atomised droplets is directed onto a fully solidified layer (6) of the same metal on the chill surface.
