Patent no. RO125770/30.12.2011<br />
Description<br />
PROCEDURE for obtaining metallic powders of<br />
binary Al-Mg alloys used for making pieces with<br />
thixotropic structure comprising the steps of:<br />
‐ controlled feeding, with a proper chemical<br />
composition prescribed for metal powders, of a 97%<br />
active aluminum wire and a Mg-cored aluminium pipe in a<br />
induction furnace with graphite crucible;<br />
‐ wire melting under protective cryolite flux layer<br />
using the induction furnace;<br />
‐ discharging, through ceramic nozzle, of the<br />
molten jet alloy on a revolving drum, placed in a closed<br />
preforming chamber protected by argon atmosphere; from<br />
the rotating drum the melted alloy is projected onto a<br />
deflector plate adjustable assembled inside the preforming<br />
chamber under a variable angle of 0 ... 45 o .<br />
APPLICABILITY DOMAIN: production of precursors for<br />
obtaining the parts with thixotropic structure.<br />
Class 7<br />
