All
PRO-MELT Furnaces are designed and built
using the highest quality materials and workmanship.
The furnace shells are constructed using sheet
steel panels with a structural steel frame. The
shell is equipped with lifting lugs to facilitate
transport and positioning
of the furnace.
Insulation:
The furnace is lined using "Lift-Out" panels made
of vacuum formed ceramic fiber on the hot face,
backed with a layer of ceramic fiber blanket.
The floor of the furnace has a layer of castable
refractory sloped toward a "Run-Out" drain, which
is backed with insulating fire brick. The easy
to operate, swing away
lid, is lined with ceramic fiber refractory
to minimize heat loss. The use of low heat storage
materials means faster heat-up and higher recovery
rates than conventional brick linings.
Heating System: The heating system features fully
supported heating elements made of Fero-Chrome-Al
wire. The elements are wound around and supported
by ceramic refractory tubes. This design provides
for free radiation of heat over the entire element
surface, allowing higher heating rates and longer
element life when compared to conventional groove-mounted
or embedded element systems.
Elements
are located all around the crucible to provide
fast, uniform, heat transfer to the melt. "Lift-Out"
element panels make it possible to change elements
from the top of the furnace without requiring
the removal of the crucible. Top access allows
the furnace to be placed closer to the casting
station since side access is not required for
routine maintenance.
Unlike "Series" wired elements all Pro-Melt elements
are independently wired. This means that a single
element failure has no effect on the operation
of the remaining elements. Furnace operation may
be continued until a convenient time arises for
repairs to be carried out.
