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:
Metal conveyor belt with adjusted mesh gauges
Electric heating, radiant or convection
Direct or indirect gas-firing
Heating with the use of external heat sources
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
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
Charge space width
Cycle time or throughput
Length of charge and discharge zone
Generated exhaust gases
Specific industry standards such as AMS, CQI-9, FDA etc.
