Forced Convenction Furnaces up to 850°C

What are forced convection furnaces up to 850 °C?

Forced convection furnaces up to 850 °C are designed for industrial heat treatment processes where very uniform temperature distribution throughout the chamber is essential. Powerful internal air circulation helps minimise temperature differences inside the working chamber and supports repeatable process results.

This category includes chamber, top-loading, shaft and bogie-hearth furnace designs available in different chamber sizes and load capacities for different batch sizes and production requirements.

Typical applications

• Tempering and stress relieving
• Annealing of metal parts
• Heat treatment of aluminium alloys
• Artificial ageing of aluminium alloys
• Preheating before further processing
• Curing and controlled heating processes
• Uniform heating of larger or heavier loads
• Batch heat treatment with repeatable results

How to choose a forced convection furnace

• Process temperature – choose 650 °C or 850 °C according to your heat treatment process
• Temperature uniformity – important for consistent results across the entire load
• Chamber volume – based on batch size, part dimensions and production capacity
• Load weight – especially important for bogie-hearth furnaces and heavy components
• Loading method – front loading, top loading, shaft loading or bogie-hearth loading
• Production volume – single batches, regular production or larger industrial workloads
• Custom requirements – chamber size, air circulation, control system or handling equipment

Forced convection furnace series in this category

• PP chamber furnaces – compact forced convection furnaces for tempering, ageing and low-temperature heat treatment
• KNC/H chamber furnaces – front-loading forced convection chamber furnaces for larger batches and industrial heat treatment
• KNC/V chamber furnaces – top-loading forced convection furnaces for vertical loading from above
• VKNC bogie-hearth furnaces – forced convection bogie-hearth furnaces for heavy or bulky loads
• SC shaft furnaces – forced convection shaft furnaces for vertical components and specific loading requirements

FAQ

When should I choose a forced convection furnace?
Choose a forced convection furnace when your process requires very uniform heating of the entire load, especially for tempering, stress relieving, annealing, artificial ageing or other heat treatment processes where repeatability is important.

What is the difference between a forced convection furnace and a radiant heating furnace?
Forced convection furnaces use circulating hot air to improve temperature uniformity, especially at lower and medium temperatures. Radiant heating furnaces transfer heat mainly by radiation and are typically used for higher-temperature heat treatment.

Which loading method should I choose?
Front-loading chamber furnaces are suitable for general batch operation, top-loading furnaces are useful when loading from above is required, and bogie-hearth furnaces are suitable for large, heavy or bulky parts. Shaft furnaces are suitable for vertically loaded components or applications with specific handling requirements.

Can LAC customize a forced convection furnace?
Yes, forced convection furnaces can be configured according to process temperature, chamber volume, load capacity, air circulation requirements, control system and handling method.
