DRIVESYSTEMS

Partners in Motion

Support at Every StageToday’s steel industry has evolved into one gigantic, complex, segment catering to the world’s requirement for automobiles, ships, construction, structures, etc. Steel plants demand peak performance on a 24x7 basis with zero-maintenance and at the highest possible efficiency levels.

With its great expertise in drive technology solutions, NORD Drivesystems is now well known in the steel industry as a systems supplier with individual project consultancy, and has made a name for itself due to the use of its motors in the harsh environment of the steel industry. Although motors only form a small proportion of the investment volume of a steel works, they are a vital part of the plant as a whole. The drive units must operate in a harsh environment, which often involves extremely high temperatures. This means that they must be appropriately designed to cope with the requirements of the steelmaking industry. NORD drive units are used for roller conveyors, which run continuously and are only rarely accelerated, and in contrast for reversing steel rolling mills, in which the direction of rolling is reversed after each rolling process. Reversing operation places extreme electrical, mechanical and thermal stresses on the drive unit. Rolling operation is characterized by the fact that the rollers, including the material to be rolled, has to be accelerated within a very short time, with rapid switching cycles, and reversal of the direction of rotation.

Delivering quality globallyNORD stands for a 45 year tradition of quality and reliability with its roots in Germany. With a global presence in more than sixty countries, every industry vertical relies on us to offer the very best. Our successful climb to the elite list of gear motor manufacturers is due to our strategy to listen to and work closely with our customers. Together with the help of our customers we have created optimal drive solutions and have had solid growth as a company as well. Our products embody an innovative combination between compact mechanics and intelligent electronics. We market and produce a complete product line of mechanical and electronic drive components including, quality gear reducers, motors, frequency inverters, servo controllers and decentralized drive technology. Together, NORD and our customers are building long term successful business relationship.

Consistent performanceNORD gearboxes come with a range of features to perform fault-lessly in the demanding environment of the steel industry - sturdy, efficient and safe.

Trusted for valueBecauseoftheharshenvironmentwithchangingloadscombinedwith high ambient temperatures ‘classic’ roller table motors are used. Some manufacturers and users still consider ‘ring-fin motor’ to be an established part of a rolling mill.

Three-phase motors with horizontal cooling fins also worked satisfac-torily in the last years in different parts of rolling mills. What matters

is that the different loads and required starting torques (acceleration) and break-down torques for a roller table are absolutely considered inthecalculations!Besidesitcanhappenthatasteelslabisblockedand that only few rollers are accelerating the slab, which means that these drives will be overloaded.

The major task of roller table drives is the deceleration and acceleration of the transported steel slab, profile or tube. In the transportation phases with constant speed relatively little power is needed. The geared motors in steel plants, especially the mill area are calculated and selected according to the high acceleration load and shock loads with a high service factor, based on the acceleration torque.
