Støtek Shaft Furnace
Shaft furnace for melting- & holding of aluminium
STØTEK Shaft furnace
Fully automatic melting- & holding
furnace, with hydraulic tilt.
Melting capacity up to 3000 kg
Aluminium pr. hour and a holding
capacity up to 20.000 kg Aluminium.
STØTEK shaft furnaces are constructed
with a very solid steel chassis and lined
with high-quality refractory products..
The furnaces are divided in two parts -
a melting shaft and a holding part for the
metal. The melting burners in the melting
shaft are controlled independently from STØTEK shaft furnaces are fully automatic
charged. This means that a signal from the shaft
indicating that there is room for additional metal
in the shaft, combined with the holding part not
being completely full, activates an automatic
charge from the elevator into the shaft..
To maintain an exact metal temperature in the
holding part +/- 3 C°, STØTEK recommends that
the holding part always be minimum two-three
times larger than the melting capacity.
This also provides a better and more
homogeneous metal quality.
The holding part can also be fitted with Al
Clean Porous Plugs to remove possible
oxides and degas the aluminium.
The chimney gas from the holding part
passes through the melting shaft for an
effective energy utilization.
