Technical data
Furnace housing
The protective gas and vacuum tight, from all sides reinforced inner housing is cooled by a fan to avoid outer wall temperatures of the housing of 180 °C, also during continuous operation.
The corresponding designed outer housing remains cool (max. 40 °C above room temperature).
The furnace bottom with a special sealing can be automatically moved up and down with a mechanism and is guided via a strand guide section.
The protective gas respectively vacuum tight bottom door is designed as explosion door (pressure limit appr. 10 – 20 mbar) and intended with turn-locks with adjustable spring pressure resistors.
On the rear side of the furnace there are connection flanges for inlet and outlet of protective gas, vacuum and the thermocouple.
Door flange, connections for thermocouple and heating elements as well as gas outlet are water cooled.
Insulation
The inner housing is lined with high-quality insulation materials (graphite or high temperature bricks as well as PCW plates). Lightweight, low energy consumption materials enable extremely short heating up and cooling down times (brick insulation excluded).
Heating
The furnace is heated on four sides by replaceable MoSi2, Mo, W or graphite heating elements, which are operated by a 3-phase thyristor unit with phase-angle and a transformer. The heating element connections are led out on the furnace rear wall.
Lateral, appr. In the middle of the furnace (seen from the rear wall), there is a PtRh-Pt double thermocouple type S (type B/C) (accuracy: class 2 according to DIN IEC part 2), which measures the temperature. A thermoelement pair leads to the temperature controller, the other one to the safety controller. A pyrometer measuring is (optionally) carried out laterally or from the cover.

1 pc. Lockable safety controller for additional protection of heating and insulation
1 pc. 3-phase thyristor unit for phase-angle and current limitation
