Description
00085/01.02.2010
The Obtaining Process of the metal powders of Al-Mg
alloys meant for the production of pieces with thixotropic
structure, consists in an adequate dosing of the active Al
solid wire and of the Mg-cored aluminium pipe, melting
under a protective layer of cryolitic flux, followed by the
continuous flowing of the alloy jet into the preforming
chamber on a rotating drum, projecting the melt onto a
deflective plate, which achieves the jet dispersion into
pulverous particles which are then deposited onto the
cooling collector bed in an inert atmosphere.
The Obtaining Process permits the producing of fibers
and/or strips of alloys subjected to melt, just by reversing
the direction of rotation of the preforming drum, without
modification of the installation..
The Obtaining Installation comprises of two feeding
mechanism for wire and for the cored pipe, which lead the
components of the binary alloy with variable advance
speeds to an induction-heated graphite crucible which is
provided with a system of nozzles wherethrough the
melted alloy flows in a laminar motion on a refractory
