Aluminium parts
Chamber furnace with air circulation
| Oven temperature | max 350 °C |
| Batch weight | 2.000 kg |
| Batch size | 1,200 x 2,000 x 2,000 mm (L x W x H) |
| Heating | Direct electric heating |
The compact chamber furnace can be loaded by forklift as well as by movable furnace grate. The furnace door can be moved and pressed on by electric motor. The chamber furnace forms the core for the following modular expandable equipment:
- Air quench / air shower
- Water/polymer quenching
- Charging equipment
- Chamber furnace line
Chamber furnace with quenching bath
| Oven temperatures | max. 560 °C |
| Heating capacity | 1.200 kg/h |
| Batch weight | 1.500 kg |
| Batch size | 1,200 x 1,500 x 1,500 mm (L x W x H) |
| Heating | Direct electric heating |
The furnace system is fed via the water quench bath using a forklift truck. The water quenching bath has a hydraulic lowering platform and can be tempered between 40 and 85°C by means of electric heating and pipe cooling. The batch is transported from the chamber furnace to the quenching bath by means of a push chain. The conversion time is less than 25s. The furnace system is used for solution annealing of aluminum parts.
Roller hearth furnace for aluminium parts
| Oven temperatures | Solution annealing max. 560 °C |
| Heating capacity | Ageing max. 300 °C" |
| Batch weight | 6,000 kg/h |
| Batch size | max. 2,000 kg |
| Heating | 1,000 x 2,000 x 2,000 mm (L x W x H) |
The roller hearth furnaces are components of a fully automated heat treatment plant for aluminum parts. The modular roller hearth plant can be individually adapted to the required heat treatment specification. The plant can also be set up in line or in a U-shape. A subsequent extension or increase in capacity can be achieved by branching or adding modules.
Batch tracking in combination with heat treatment recipe management allows different components to be treated simultaneously in the furnace system.
Solution annealing in salt bath
| Salt bath temperatures | max 520 °C |
| Heating capacity | 1.400 kW |
| Useful space (L x W x H) | 14,000 x 1,500 x 3,000 mm (L x W x H) |
| Heating | Direct electric heating |
| Permissible salt bath medium | Nitrate salt AS 300 |
The plant is used for solution annealing of components made of aluminum alloys in a molten salt bath. The plant is installed at ground level, has 4 separately movable lids and is fed with the material to be treated from above via a crane system.
The temperature control of the molten salt is optimized in such a way that the temperature uniformity in the working chamber of class 1, according to AMS2750E, is achieved with a variation of +/- 3 K (°C).
