Description
It is flux in form of tablet used for degassing
aluminium alloys melt. The tablets release a quantity
of Nitrogen gas for degassing procedure of alumnium
melt. Also the cleaning of melt (non-metallic inclusions
(oxide layers, carbides and others) removing) due to
the inclusions float effect under degassing. The dry
and powder-type dross with low metallic content was
obtained after cleaning and degassing operations in
case of using degassing tablets together with coveringrefining
fluxes.
Applications
degassing operation of aluminium melt
under melting / holding procedure. Improving the aluminium
melt cleaning (in case of degassing tablets and
covering-refining fluxes mutual using) for wide range of
casting techniques (high pressure die casting, low pressure
die casting, gravity casting in permanent and sand
molds, others) and different furnace types or ladles.
Method of use
1. The degassing tablets introduce in melt by
degassing plunger tool under melt surface to
the bottom of furnace crucible or furnace/ladle
hearth.
2. The temperature of treatment must be in the
range: 620°С – 750°С.
3. The degassing plunger must be in melt till
ending of reaction.
4. After reaction the melt rest time must be 5-10
minutes. The melt can be pouring after skimming
the dross.
