Forced convection bogie hearth furnace for large charges up to 850 °C
Need to heat treat large, heavy or bulky charges evenly while maintaining precise process control at higher temperatures?
The VKNC forced convection bogie hearth furnace up to 850 °C is designed for industrial processes where easy loading, forced air circulation and even temperature distribution are essential.
When is this furnace the right choice?
- You need thermal processing up to 850 °C
- You process large, heavy or bulky charges
- You require forced air circulation
- You need even temperature distribution in the working chamber
- You want easier loading and unloading using a bogie hearth system
- You work with annealing, tempering, ageing, curing or preheating
The VKNC furnace combines a bogie hearth loading system with powerful air circulation. The charge is loaded onto the bogie outside the furnace and then moved into the chamber. Forced air circulation helps distribute heat evenly through the working space, while the door closing system supports tight sealing and reduced heat losses. The 850 °C version is equipped with a refractory circulation insert designed for higher-temperature operation.
Key features:
- Maximum temperature 850 °C
- Recommended operating range 300–800 °C
- Forced air circulation
- Bogie hearth loading system
- Refractory circulation insert for higher-temperature operation
- Large chamber volumes from 1000 to 7200 L
- Maximum bogie load up to 4000 kg
- Ht205 controller with 30 programmes of 15 steps each
- Resistance heating with meanders on the furnace sides
- Insulation using ceramic-fibre blocks
- Limit unit
Typical applications
The VKNC furnace is suitable for industrial heat treatment under normal atmosphere, especially where large or heavy charges require forced air circulation and repeatable temperature conditions.
- Normalisation annealing
- Solution annealing of non-ferrous metals
- Annealing of non-ferrous metals
- Soft annealing
- Annealing for stress relieving
- Recrystallisation annealing
- Artificial ageing
- Low-temperature tempering
- High-temperature tempering
- Curing
- Preheating
Typical industries
- Heat treatment shops
- Foundries and casting operations
- Automotive suppliers
- Metal processing
- Mechanical engineering
- Toolmaking and mould production
- Industrial production with large or heavy components
Main benefits
- Easy loading of large and heavy charges
- Even temperature distribution thanks to forced air circulation
- Suitable for high bogie loads up to 4000 kg
- Higher operating range than the 650 °C version
- Repeatable heat treatment results for large batches
Suitable for customers who need a forced convection bogie hearth furnace for large, heavy or bulky charges up to 850 °C.
For processes up to 650 °C, consider the VKNC 650 °C forced convection bogie hearth furnace. If you need a front loading chamber furnace, consider the KNC/H 850 °C forced convection chamber furnace. If top loading is preferred, consider the KNC/V 850 °C forced convection chamber furnace.
For processes up to 650 °C, consider the VKNC 650 °C forced convection bogie hearth furnace. If you need a front loading chamber furnace, consider the KNC/H 850 °C forced convection chamber furnace. If top loading is preferred, consider the KNC/V 850 °C forced convection chamber furnace.
