Developments in Hot Forming to Satisfy Product Demands
Shahram Sheikhi, senior manager — metal forming technology, and Carl-Dieter Wuppermann (pictured), executive member of the management board, Steel Institute VDEh, Düsseldorf, Germany (Sheikhi@slv-duisburg.de, carl.wuppermann@stahl-zentrum.de)
Tighter dimensional tolerances, increased yield, good formability and higher steel strengths are a few of the demands on steel products. These demands drive the innovations
in technology and the progress in processes and automation. |

New Fault Detection Technology for Electric Arc Furnace Electrical Systems
Ljubomir Kojovic, chief power systems engineer, and Martin T. Bishop, chief engineer — Systems Integration Group, Cooper Power Systems, Franksville, Wis. (ljubomir.kojovic@cooperindustries.com, marty.bishop@cooperindustries.com); and Dharam Sharma, staff engineer, Nucor-Yamato Steel Co., Armorel, Ark. (dsharma@nucor-yamato.com)
Traditional EAF transformers were not
protected individually. New technology using Rogowski Coil current sensors allows
conventional overcurrent devices to be set as a true backup protection device, improving both fault detection and security of operation. |
