Outokumpu Chooses ABB Variable-Speed Drives

ABB has won a GBP1.6m order to supply Outokumpu with variable AC drives for the fume-extraction system at its Sheffield plant. The project will involve ABB supplying four 1.2MW fan drive systems to provide fume extraction for the Outokumpu stainless melting and continuous casting (SMACC) facility. Each package will consist of an ABB industrial drive, a transformer and an ABB high-voltage motor.

The systems will provide fume extraction for the melting shop and for individual units such as the electric arc furnace and the argon oxygen decarburiser. Replacing the existing direct-on-line motors, the variable-speed drive fans will produce significant energy savings and achieve an annual saving of more than 5,000 tonnes of CO2.

The contract includes the supply of four motor bedplates, removal of old equipment, a service contract, project management, integration of control equipment and an extended 36-month warranty. Installation is scheduled for late July and early August 2010.
