Laboratory and factory metal and
alloy melting processes.
FF furnaces consist of 3 different capacity types offering a number
of advantages:
Simple and clean melting and bonding operations as regards precious
and non precious metals.
FF furnaces can be heated with silicon carbide elements, which
ensure high heat concentration within a small space. The heating
elements are set inside appropriate spaces in the hot chamber in
order to prevent any contact with the crucible.

| Temperature control device |
Automatic temperature control device
with instant temperature display. It provides maximum heating power
up to the temperature preset. A proportional device supplies variable
quantities of power to the resistors in order to prevent temperature
variations. |
| |
| Thermocouples |
Platinum/Rhodium thermocouples shielded
by a gas-proof ceramic covering set outside the crucible |
| |
| Power control |
The increasing resistivity of the
resistors due to ageing is manually offset by an electronic
device and related power gauge. |
| |
| Heat insulation |
The furnace is coated with aluminium
silicate refractories, which are classified according to their
different thermal conductivity based periscopic resistance. This
solution represents the best compromise between heat insulation
and campaign of a furnace in working conditions. |
| |
| Crucibles |
The multipurpose crucibles used
in FF furnaces are standardized and the size also features on the
trademark of the actual furnaces. Apposite pliers are supplied
to remove and tilt the crucible. Tilting furnaces sharing the same
features are available upon request. (RF trademark).

| BUILDING FEATURES |
FF furnaces are made of painted
steel; they are compact and can also be assembled on a worktop.
The control devices are fitted in the steel frame and set inside
suitably aired spaces. The cover is mounted with a parallelogram
that keeps the warm side of the insulating plug facing downwards.
When the cover is removed the resistors are excluded. The power
supply is V220 monophase; the electric equipment complies with
I.E.C. standards. |
