A new solution for aluminium powder producers
Melting furnace for producing aluminium powder
Dross Engineering and Toyal
Europe have just commissioned an innovative aluminium powder production
line. The line, installed at Toyal’s Accous plant in South-West France,
guarantees regular, exceptionally high quality production of aluminium
Dross Engineering’s team of engineers designed and built the original
powder production line some ten years ago based on standard 25kg ingot
feedstock. However, such feedstock is being phased out from the pure and
extra pure aluminium market to be replaced by 450 to700 or even 800kg
Jumbo ingot and T bar. Such feedstock makes regulating bath levels
impossible with conventional equipment. Faced with this difficulty, Toyal
Europe approached Dross Engineering to help find a solution.
The new installation is equipped with twin dry hearth electric element
melting furnaces. T bar and jumbo ingot is melted on the dry hearth and
the molten aluminium runs into the furnace holding compartment. The key to
the success of the installation is found in the fact that the melting
furnaces are pressurized and act as extremely accurate dosing units. The
furnaces supply a constant and regular stream of molten metal to the
atomising well that is heated by electric immersion heaters. The metal
level in the atomising well is maintained to within +/- 3mm.
The fully automated installation is operated 24/7 by a single technician,
whose main responsibility is to charge the melting hearths alternatively.
The supervisor programme controls the process throughout from jumbo ingot
to conditioned aluminium powder.
