The conveyor belt furnace is loaded via the loading device. The conveyor belt is divided into three adjustable zones by means of suspended separators.

The furnace has 4 control zones with 2 air circulation fans and 2 air guiding devices. The heating is done by electric screw-in heating elements, which are installed and removed from the side.

The control elements measure the temperature of the air entering the batch chamber. This prevents the components from overheating.

The charging can be carried out in bulk in grid boxes, or via vibrating feeders or conveyor belts, and can be operated in multiple lanes.

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.

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 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.
