ArcelorMittal Orders Converter Tilting Drive from SMS Siemag
08/16/2011 - SMS Siemag will design, manufacture and install a new tilting drive for ArcelorMittal’s converter at Gent, Belgium.
ArcelorMittal Gent, Belgium, has placed an order with SMS Siemag, Germany, for the design, manufacture and installation of a new tilting drive for its converter.
The new drive will replace an existing drive that has been operated by the company for forty years. Rated for a torque capacity of 7,500 kNm, the new drive is among the most powerful converter tilting drives SMS Siemag has supplied to date.
SMS Siemag’s scope of supply includes the main gear unit, primary gear units, torque arms, mounting device and pneumatic emergency drive. The gear unit and the trunnion pins are connected to each other by a special process. Compared with the connection via a tangential key, the installation is carried out by means of an oil press fit, resulting in a lower sectional area reduction of the drive-side trunnion pin. The design also facilitates dismantling and installation for maintenance purposes.
In the event of failure of one of the four primary gear units, it is possible to continue operation for a certain period. The drive itself can be operated for a brief period with two primary gear units or, in the case of power failure, with the nitrogen motors.
SMS Siemag will manufacture the tilting drive at its workshops in Hilchenbach and deliver it to Belgium in August 2012.
SMS Siemag AG is a company of the SMS group, which is, under SMS Holding GmbH, a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. It consists of the two Business Areas SMS Siemag and SMS Meer. In 2010, some 9,200 employees worldwide generated a turnover of EUR 3 billion.
