Drive solutions for the steel industry

NORD DRIVESYSTEMS supplies well-thought-out, future-proof solutions for all processes in steel and aluminium plants throughout the world, which cater for current and future requirements. NORD drive technology achieves long lifetimes, even under extremely harsh conditions. Even under extreme electrical and mechanical loads, the systems ensure full performance and reliable operation at all times.

Continuous performance
NORD gear units have a number of features that enable trouble-free operation in the demanding environment of the steel industry - robust, efficient and safe.

Stable value
Due to the harsh environment with alternating loads in combination with high ambient temperatures, classic rolling mill motors are used. Some manufacturers and users still consider the "ring-rib motors" an integral part of a rolling mill. Three-phase motors with horizontal cooling fins have also been successfully operated in various rolling mill areas in recent years. Important in this context: The various loads and required acceleration and braking torques of a roller mill are fully included in the calculations!

In addition, it can happen that a slab blocks and is accelerated by only a few rollers, which overloads the respective drives. The main task of the roller table motors is to decelerate and accelerate the slabs, profiles or pipes on the system. Relatively little power is needed in the transport phases with constant speed. Geared motors in steel mills, especially in the rolling mill, are calculated and selected with a high operating factor based on the acceleration torque due to the high acceleration work and the impact loads.

SMS Group GmbH

Robust drive systems for reversing rolling mill in the desert

The extreme operating conditions in a rolling mill in Bahrain require reliable drive technology. Drives must be able to withstand extreme temperatures, high loads and shocks, while continuing to operate reliably. SMS group GmbH therefore opted for NORD drive solutions.
