Foundry:Pure Gold Recycler
Objectives:• Constant crucible life• Increase of crucible life• No contamination of the Gold
during fi rst melt with new crucible
Alloy:99,99 % Au
Crucible size:DURATEK PM Cylinder with spout
Crucible capacity:400 kg Gold
Application:Induction melting of fi ne-gold returns
Benefi ts:• Very high erosion resistance• Very high strength• Very good homogeneity
Problems:• Contamination of fi rst melt with
new crucible• Inconstant crucible life of
+/- 20 melts• Therefore unexpected crucible
exchange disturbing production
Improvements:• DURATEK PM does not show any
contamination of Gold from the beginning
• 50 % longer crucible life constantly achieved
• Crucible exchange can be better planned now
