Furnaces with Radiant Heating

What are furnaces with radiant heating?

Furnaces with radiant heating are designed for high-temperature industrial heat treatment where heat is transferred mainly by radiation from the heating elements to the load. They are suitable for processes requiring higher operating temperatures, such as hardening, annealing, normalising, solution annealing and preheating.

This category includes chamber furnaces for different batch sizes, load capacities and production requirements, with maximum operating temperatures up to 1280 °C.

Typical applications

• Hardening of metal parts
• Annealing and stress relieving
• Normalising and solution annealing
• Preheating before forging or forming
• Heat treatment of tools and components
• High-temperature batch processing
• Thermal processing of ferrous and non-ferrous materials

How to choose a radiant heating furnace

• Process temperature – according to your material and heat treatment process
• Chamber volume – based on batch size and part dimensions
• Load weight – important for heavy parts and larger batches
• Heating method – radiant heating for high-temperature processes
• Loading method – chamber loading according to part size and handling requirements
• Process control and documentation – temperature control, documentation or process validation

Furnace series in this category

• PK chamber furnaces – industrial chamber furnaces for larger batches and high-temperature heat treatment
• PKE chamber furnaces – compact chamber furnaces for smaller batches and high-temperature industrial processes

FAQ

When should I choose a furnace with radiant heating?
Choose a radiant heating furnace when your process requires higher temperatures, typically for hardening, annealing, normalising, solution annealing, preheating or other high-temperature heat treatment applications.

What is the difference between radiant heating and forced convection?
Radiant heating is typically used for higher-temperature processes where heat is transferred mainly by radiation. Forced convection furnaces use circulating hot air and are suitable for applications where very uniform temperature distribution is required at lower or medium temperatures.

Which furnace should I choose: PK or PKE?
PK chamber furnaces are suitable for larger batch sizes and higher load capacities. PKE chamber furnaces are more compact and suitable for smaller batches or workplaces with lower capacity requirements.

Can LAC customize a radiant heating furnace?
Yes, radiant heating furnaces can be configured according to chamber size, load capacity, control system, process requirements and handling method.
