Patent no. RO125770/30.12.2011
Description
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.
