The method relates to metallurgical recycling of waste products, preferably titanium
alloys chips scrap.
Accordingly after crushing and cleaning, the chip scrap is subjected
to vacuum-thermal degassing (VTD); the chip scrap is pressed into briquettes; the
briquettes are placed into a mould allowing sufficient remaining space for the
addition of molten metal alloy; the mould is pre-heated before filling with the
molten metal alloy; the mould remaining space is filled with molten metal alloy.
After cooling, the electrode is removed from the mould.
The method provides a means for 100% use of chip scrap in producing consumable
electrodes having increased mechanical strength and reduced interstitial impurities
content leading to improved secondary cast alloys.
