Roller-Hearth Furnaces

For tempering and annealing, for GKZ- annealing, for martensit and bainit hardening, Engineering loading and unloading door, Engineering gas tight roller bearing - system, for heat treatment of distortion-sensitive components under protective-gas atmosphere.

We are a company with global operations and a highly motivated workforce engaged in formulating special solutions for the heat treatment of steel.

Why Choose Us?

Roller hearth furnace systems are deployed in all heat treatment processes. Depending on the type of heat treatment, they are expanded by way of oil, salt or gas quenching systems, as well as peripheral equipment for total automation.

Their special roller design facilitates very high roller loads and, thus, extremely high throughput capacities. The work pieces to be treated may, depending on their configuration, be charged directly on the hearth rollers, as a batch on special underlays or as bulk materials in charging racks.

They are predominantly deployed in companies engaged in large-scale production.

Rotary hearth furnaces are among the standard products offered by our company.

They are manufactured in all sizes and, depending on their specific deployment, can be equipped with the most diverse hearth superstructures. Special slotted and individually removable doors permit multi-level operation. Rotary hearth furnaces in these design series are installed ready for connection in our establishment and are delivered after a trial run has been conducted. Assembly and commissioning timelines are, thus, kept to an absolute minimum.

Pusher-type furnace systems are deployed, in particular, in large-scale production.

The high level of reproducibility of the heat treatment results and the level of automation make them particularly cost-effective. Depending on the deployment and the desired throughput capacity, single and multi-line systems are deployed. Combined with the relevant peripheral equipment, such as a tempering furnace and pre-oxidation furnace, washing unit, grate transportation and storage units, as well as process visualisation and documentation, fully automated operation with minimal staff deployment is feasible.

Hood-type furnace systems are deployed when extremely heavy and large batches must be heat-treated.

They are deployed particularly for heat treatment processes, such as gas carburising, carbonitriding and annealing. Combined with the relevant peripheral equipment, such as tempering furnaces, cooling stations and cooling manipulators, washing units, transportation and storage zones, as well as process visualisation and documentation, fully automated operation is feasible in this type of furnace, too.

The deployment of Paternoster furnaces for tempering hardened components is of particular merit owing to their space-saving footprint and seamless integration in the fully automated process flow. Fully automated feeding units or robotic loading are feasible. These systems, too can be heated by gas or electricity as required.

Belt furnace systems are deployed in various heat treatment processes.

They are produced in the most diverse design variants. Depending on their specific deployment, a temperature range of 160 °C – 1000 °C is observed. The belt furnace is a universal type of system, deployed for bulk materials also in the large-scale production of small parts for the thermochemical procedures hardening, carburisation and carbonitriding. Depending on the procedure, the systems are equipped with oil or gas quenching basins and are generally furnished with automatic loading and unloading equipment.
