Description<br />

00085/01.02.2010<br />

The Obtaining Process of the metal powders of Al-Mg<br />

alloys meant for the production of pieces with thixotropic<br />

structure, consists in an adequate dosing of the active Al<br />

solid wire and of the Mg-cored aluminium pipe, melting<br />

under a protective layer of cryolitic flux, followed by the<br />

continuous flowing of the alloy jet into the preforming<br />

chamber on a rotating drum, projecting the melt onto a<br />

deflective plate, which achieves the jet dispersion into<br />

pulverous particles which are then deposited onto the<br />

cooling collector bed in an inert atmosphere.<br />

The Obtaining Process permits the producing of fibers<br />

and/or strips of alloys subjected to melt, just by reversing<br />

the direction of rotation of the preforming drum, without<br />

modification of the installation..<br />

The Obtaining Installation comprises of two feeding<br />

mechanism for wire and for the cored pipe, which lead the<br />

components of the binary alloy with variable advance<br />

speeds to an induction-heated graphite crucible which is<br />

provided with a system of nozzles wherethrough the<br />

melted alloy flows in a laminar motion on a refractory<br />

Class 7<br />
