Many international steel-producing companies depend on the reliability of our safety couplings. The most critical requirement is that these components need to be wear-free, even under the most extreme loads.
Of all industrial steel production processes, the transformation of iron ore into steel is one of the most sensitive, high-risk and consequence-ridden manufacturing steps. This processing step is carried out in the converter.
Avoiding high-cost downtimes is imperative in this production phase. Our rugged mechanical breakaway couplings protect the drives of the ladle car in case of a crash, keeping outages to a minimum and ensuring reliable planning with minimized risk of damages.

COLD AND HOT-ROLLED STRIP PRODUCTION - CONTINUOUS MEASUREMENT AND QUALITY CONTROL
The mill stand requirements for producing steel pipes are high. Pipe diameters of up to 1,800 mm are continually subjected to measurement and quality control during the production process. The drive performance in this case is in the heavy applications torque range.
Overload couplings are used between the transfer units and the rollers to be driven in the stand in conjunction with an automatic re-engagement function. Compared to conventional solutions, these heavy-duty safety couplings are durable for a lifetime and are maintenance-free. Accessibility to the safety couplings is not required thanks to the re-engagement function. In addition, the coupling helps to minimize downtimes in the case of an overload in the mill stand, e.g. due to a collision, thus lowering maintenance costs.
Whether used in cold-rolled strip, hot-rolled strip or roll forming production. The material is transported to the next step anywhere in production with separately driven rollers. When a roller drive fails, the remaining drives have to absorb the force for further transport. This frequently has a negative impact on the surface coating of the rollers and thus on the service and useful life of the system.
It is therefore essential to prevent coupling failures on the roller drive. Since the material to be transported often emits temperatures of over 180°C, spider couplings are not a long-life, durable solution. Even curved-tooth couplings are not an alternative for the application due to the maintenance required. Metal bellows couplings, however, offer a real alternative. In addition to their rugged design, these compensate for misalignments or thermal expansion caused during installation. To meet a specific operating requirement for impact resistance, these couplings are also optionally provided with an integrated safety system.
