For continuous processes with fixed cycle times, such as core or mold drying or for preheating molds in investment casting, continuous furnaces or rotary hearth furnaces are often the right choice. Depending on the process, different working temperatures, conveying concepts and heating concepts can be used here. 

The conveyor technology is tailored to the required working temperature, geometry and weight of the charge and to the requirements regarding available space and integration into the process chain. The conveyor speed and the number of control zones are defined by the process specifications. 

Conveyor Concepts

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

Heating Systems

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

Basic Configuration Criteria

• Conveyor speed
• Temperature uniformity
• Operating temperature
• Process curve
• Work 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.
• Other individual customer requirements
