NORD Drivesystems
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.
