INSTALLATION AND PROCEDURE for obtaining<br />
metallic powders of binary Al-Mg alloys used for making<br />
pieces with thixotr<strong>op</strong>ic structure comprising the steps of:<br />
• controlled feeding, with a pr<strong>op</strong>er chemical composition<br />
prescribed for metal powders, of a 97% active aluminum<br />
wire and a Mg-cored aluminium pipe in a induction<br />
furnace with graphite crucible;<br />
• wire melting under protective cryolite flux layer using<br />
the induction furnace;<br />
• discharging, through ceramic nozzle, of the molten jet<br />
alloy on a revolving drum, placed in a closed preforming<br />
chamber protected by argon atmosphere; from the<br />
rotating drum the melted alloy is projected onto a<br />
deflector plate adjustable assembled inside the<br />
preforming chamber under a variable angle of 0 ... 45 o .<br />
APPLICABILITY DOMAIN: production of precursors for<br />
obtaining the parts with thixotr<strong>op</strong>ic structure.<br />
