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