Solution annealing

Roller hearth furnace for aluminum parts

Oven temperaturesSolution annealing max. 560 °C
Heating capacityAgeing max. 300 °C"
Batch weight6,000 kg/h
Batch sizemax. 2,000 kg
Heating1,000 x 2,000 x 2,000 mm (L x W x H)

The roller hearth furnaces are part of a fully automated heat treatment system for aluminum parts. The modular roller hearth system can be individually adapted to the required heat treatment specifications. The system can also be set up in line or in a U-shape. Subsequent expansion or increased output 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 a salt bath

Salt bath temperaturesmax 520 °C
Heating capacity1.400 kW
Useful space (L x W x H)14,000 x 1,500 x 3,000 mm (L x W x H)
HeatingDirect electric heating
Permissible salt bath mediumNitrate 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).
