Conveyor furnaces
Conveyor belt furnace for thermoforming
| 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 oven 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. Heating is by means of electric screw-in heating elements which are inserted 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 |
Charging can take place in lattice boxes or via vibrating chutes or conveyor belts as bulk material and can be operated in multiple lanes.
The furnace has 4 control zones with 2 air circulation fans and 2 air guiding devices. Heating is done with electric screw-in heating elements which are installed and removed from the side.
A cooling device is located directly behind the furnace, which provides cooling of the batch 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 plant is fed via a pusher, which pushes the material to be treated from an upstream conveyor belt onto the oven 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 oven for bainitising 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 chute. 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 and a flame curtain are provided for the furnace inlet. Depending on the height of the workpiece, the kiln inlet can be adjusted to prevent heat loss.
The furnace outlet is formed by a drop shaft. 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 drop-out shaft with refractory brick, and the ceiling with ceramic fibre.
Cast plate conveyor furnace
| Oven temperatures | max 960 °C |
| Heating capacity | 1.100 kg/h |
| max. belt load | 152 kg/m² |
