Abstract
A process for manufacturing large diameter, spray formed billets, rings, or tubular forms by spraying atomized molten metal onto a rotating surface. The rotating surface has a collector surface that is maintained at a predetermined temperature or reheated to the predetermined temperature by an external heat source. The external heat source impinges upon the collector surface to form a reheated or preheated zone. The external heat may be provided by a laser, high temperature flame, plasma arc, electric induction or radiation source. The molten metal is sprayed onto the collector surface in the reheated or preheated zone. Apparatus for carrying out the process is also disclosed.
