Burn-out furnace APE800 and APE800a

2. Intended use of the furnace

The furnace is intended for heating and drying trays (metal moulds) which are

applied in the process of jewellery casting with the use of stay-in-place wax method.

The construction and technical parameters of the furnace enable to use it for all casting

mass which are available on the market.

The application of temperature program selector enables the control of the heating

process with the priority of temperature over the time. It is possible to programme two

independent programs with sixteen sections in each one.

3. Furnace design – general comments

The furnace is constructed of two joined units which constitute one entity. The

first unit is a furnace which consists of a steel (or stainless steel – depending on the

order) construction, a heat insulation layer (40 mm) on each wall of the chamber, electric

and resistance heaters and a thermocouple which is placed in the heating chamber. The

second unit is a temperature program selector with the semiconductor joining element.

The furnace is equipped with the set of heatproof ceramic tiles which constitute the

panelling of the furnace ground. Its purpose is to protect the heatproof fibre from

damage.

WARNING: Provided socket may resemble a three-phase socket, but its application and

connection is completely different.

WARNING: Using metal trays as the furnace floor protection is impermissible. It cannot

be allowed to let wax remnants cover the furnace floor.

WARNING: The furnace structure allows the wax to soak into the bottom part of the

furnace chamber.

WARNING: Cooling down the furnace chamber with the use of fans or other appliances

extorting air circulation is impermissible.

WARNING: Burnt out trays should be previously dried in the drier in order to remove

the casting wax.
