Conveyor belt furnace for hot forming
Oven temperatures | 460 - 500 °C |
Heating capacity | 600 kg/h |
Part weight | 3 kg |
Throughput dimensions (width x height) | 1.000 x 200 mm |
Heating | Direct electric heating |
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.
Conveyor belt furnace for tempering
Oven temperatures | 460 - 500 °C |
Heating capacity | 400 - 600 kg/h |
Part weight | 1 kg |
Throughput dimensions (width x height) | 1.000 x 180 mm |
Heating | Direct electric heating |
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.
The furnace has 4 control zones with 2 air circulating fans and 2 air guiding devices. The heating is done with electric screw-in heating elements, which are installed and removed from the side.
Directly behind the furnace is a cooling device, which provides cooling of the charge with supply and exhaust fans.
Conveyor belt furnace for tempering with cooling section
Oven temperatures | 175 - 250 °C |
Heating capacity | 360 kg/h |
Part weight | 3 kg |
Throughput dimensions (width x height) | 1.200 x 200 mm |
Heating | Direct electric heating |
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.
Conveyor belt furnace for bainitizing springs
Oven temperatures | 950 °C |
Heating capacity | 100 kg/h |
Part weight | 4 kg |
Throughput dimensions (width x height) | 500 x 60 mm |
Heating | Indirect electric heating |
Oven atmosphere | Nitrogen / methanol |
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.
Chain furnace for hot forming
Oven temperatures | 400 - 600 °C |
Heating capacity | 600 kg/h |
Part weight | variable |
Passage width | 400 x 800 x 200 mm (L x W x H) |
Heating | Direct electric heating |
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.
Conveyor chain furnace for warming up
Oven temperatures | 280 °C |
Heating capacity | 600 kg/h |
Batch weight | variable |
Throughput dimensions (width x height) | 1.300 x 160 mm |
Heating | Direct electric heating |
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.
