Directly behind the furnace is a cooling device, which provides cooling of the charge with supply and exhaust fans.

The system is fed by a pusher which pushes the material to be treated from an upstream conveyor belt onto the furnace belt. The oven belt also runs through the cooling section and transports the material to be treated to the chute, which connects to the unloading section.

The furnace is divided into three heating zones with 6 heaters each, as well as a methanol splitter with 3 heaters located at the outlet drop shaft. A hot gas circulator circulates the protective gas atmosphere.

The belt runs over running and deflecting rollers as well as a tensioning device with guide rollers at the kiln inlet.

A height-adjustable bulkhead plate, as well as a flame curtain, is provided for the furnace inlet. Depending on the workpiece height, the kiln inlet can thus be adjusted to prevent heat loss.

The furnace outlet is formed by a drop chute. Through this, the workpieces fall from the belt directly into the salt bath below.

The furnace walls and floor are insulated with lightweight refractory brick, the dropout shaft with refractory brick, and the ceiling with ceramic fiber.

The track width of the two-strand chain conveyor is variably adjustable between 450-750mm and is driven by a servo motor. Thus, different stabilizer types can be driven through the plant.

The furnace is equipped with 3 heating zones, each of which is equipped with 2 adjustable cold air gas burners and a hot gas circulator.

The cooling module can be structurally separated from the furnace or directly integrated into the furnace transport system.

The parts run through the oven in multiple strands. The drive cycles through the 4 heating zones, each of which is equipped with a hot gas circulator.

Loading & unloading can be done by robots as well as by manual loading.

The round or profiled tubes are provided by the magazine. The tubes travel via the conveyor belt onto a roller conveyor. On their way into the furnace, the tubes are measured by a light barrier and positioned in the center of the furnace.

Controlled by a cam disk, the pipe is pushed onto the conveyor chain by a pneumatic pusher.

Complete kiln line including loading and unloading, as well as cooling station.

Charged furnace grates or baskets are fed into or discharged from the furnace via pneumatic transfer cars. By means of corresponding loading recipes, a wide variety of batches can be parameterized for loading and unloading.

The carriages are transported through the oven via two steel conveyor chains. Incremental encoders at the chain deflections allow the transfer positions of the carriages to be transferred to robots or gantry grippers with millimeter accuracy, irrespective of temperature and aging-related chain elongation.

The workpieces are placed by robot through the door onto the support, which is connected to the slewing ring. The six-tier turntable is driven by a geared motor and rotated further by a certain angle of rotation so that an already heated workpiece can be removed.

To prevent excessive heat loss during loading and unloading of the tempering furnace, there are 3 furnace doors.

In the cooling section, the workpieces are cooled down and then placed on the discharge conveyor by means of robots.

The rotary hearth is loaded or unloaded through a portal on two levels. The components are transferred to the hardening press. Directly after this, the components are linked to the washing machine and finally to the belt tempering furnace with aftercooling section.

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

The furnace system is supplied via the water quenching bath, which is loaded using a forklift truck. The water quenching bath has a hydraulically lowerable platform and can be tempered in a range of 40 to 85°C using electric heating and pipe cooling mechanisms. The transfer of the charge from the chamber furnace to the quenching bath is facilitated by a push chain system with a fast changeover time of less than 25 seconds. This furnace system is primarily used for solution annealing of aluminum parts.

The activation plant is used to remove the passivating metal oxide layer from stainless steel workpieces. This is necessary in order to be able to carry out a nitriding process and obtain a hard surface. Depending on the shape and size of the workpieces, they are brought into the treatment room in baskets or charging racks.

The gas-tight furnace has a hot gas circulator, a methanol splitter and a gas supply panel for propane, air, nitrogen and methanol.

The furnace has a heated furnace length of 3000 mm with a door at the inlet and outlet. The oil bath is equipped with a lowerable roller conveyor which feeds the charges to the downstream washing process.

The furnace has a hot gas circulator, a methanol splitter and a gassing panel for propane and air, nitrogen and methanol. The furnace has a heated furnace length of 3000 mm with one door each at the inlet and outlet.

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.

The austenitizing furnace is part of a fully automated heat treatment plant with upstream & downstream processes, such as loading & unloading, pre & salt washing, and drying and weighing. The furnace is equipped with an inlet lock and is directly connected to the salt quench bath.

The plant is used for quenching and tempering of steel plates at a working temperature HTO of 870°C to max. 920°C, quenching with water and subsequent stress-relieving annealing at a working temperature NTO of 250°C to max. 500°C.
