High-temperature hood furnaces lift-bottom

High-temperature hood furnaces in lift-bottom design
T max. 1500 °C, 1600 °C, 1750 °C and 1800 °C

Information

Broad range of standard furnaces with a chamber volume of 70-2000 l
The range of models includes hood furnaces with a fixed or moveable table
Also with shuttle table systems (turntable or dual-table systems) for semi- or fully automatic operation.
Furnaces supplied in customised configurations to match systems precisely to the desired processes.
All furnace models excel with maximum precision and convenience as well as short heat-up and cooling times and low power consumption.
For temperature ranges between 1500 °C and 1600 °C with SiC heating elements, and between 1600 °C and 1800 °C with MoSi₂ heating elements
Outer housing with robust, aesthetic frame construction
Double-walled housing with forced cooling, hence very low outer-wall temperatures
Proven electromechanical system for smooth, shock-free table movement
Furnace insulation made of high-quality aluminium oxide fibre materials with low thermal mass, rapid heating and cooling possible; exhaust opening in furnace roof
Reinforced bottom for heavy batches
Labyrinth seals in table and hood ensure tight closure
Heating from all four side walls, excellent temperature uniformity in the furnace chamber
Cutting-edge switching and control system, thyristor-controlled heating elements, high-precision furnace regulation, wear-free, noiseless

Model variants

Hood furnace in lift-bottom design with two furnace chambers and a double turntable or shuttle table The tables are lowered electromechanically, swivel outwards and are raised to working height. Both tables are positioned in front of the furnace for loading and unloading and are then moved simultaneously into the two furnace chambers. The table can also be moved alternately into the one or other furnace chamber.

: Additional equipment

Additional equipment:

Cooling fan
For better ventilation of the furnace chamber and for reducing cycle times. Fan is operated automatically by the controller, fan speed can be pre-selected segment-wise.
Stainless steel exhaust hoods
For controlled discharge of exhaust gases and hot air from the furnace, adapted to furnace dimensions, custom-built in stainless steel and with matching flange.
Exhaust air purification systems
Add-on for furnace systems, with catalytic or thermal exhaust air purification systems as integrated unit.
Automatic exhaust flaps in furnace roof
Start-up switch
Fully automatic furnace regulation
Air preheating for debinding processes
Protective gas operation
