Continuous Furnaces Electrically Heated or Gas-Fire Pecka za Visoka Temperaturad

Continuous furnaces are the right choice for processes with fixed cycle times such as drying or pre-heating, curing or degassing, etc.. The furnaces are available for various temperatures up to a maximum of 1000 °C. The furnace design depends on the required throughput, the process requirements for heat treatment and the required cycle time. The conveyor technology (e.g. belt, rollers) is tailored to the required working temperature and the geometry of the charge. The conveyor speed and the number of control zones are defined by the process specifications.

Alternative furnace design subject to process specifications:

Conveyor concepts

• Conveyor belt
• Metal conveyor belt with adjusted mesh gauges
• Drive chain
• Roller conveyors
• Pusher-type furnace

Heating systems

• Electric heating, radiant or convection
• Direct or indirect gas-firing
• Infrared heating
• Heating with the use of external heat sources

Temperature cycles

• Control of working temperature across the whole length of the furnace, such as for drying or pre-heating
• Automatic control of a process curve applying defined heat-up, dwell and cooling time
• Control of a temperature curve including a final quenching of the charge

Process atmosphere

• In air
• In non-flammable protective or reactive gases such as nitrogen, argon or forming gas
• In flammable protective or reactive gases such as hydrogen incl. the necessary safety technology

Basic configuration criteria

• Conveyor speed
• Temperature uniformity
• Operating temperature
• Process curve
• Charge space width
• Charge weights
• Cycle time or throughput
• Length of charge and discharge zone
• Generated exhaust gases
• Specific industry standards such as AMS, CQI-9, FDA etc.
