Tenova Goodfellow Technology Commissioned at Evraz Claymont Steel
Apr. 28, 2010 Tenova Goodfellow has successfully closed another project at Evraz Claymont Steel with the commissioning of the EFSOP Holistic Optimization® technology on the company’s existing 160-ton electric arc furnace (EAF). Application of the technology provided automation of the fourth-hole damper and burn injector profile.
Final acceptance for project closure came in January 2010, which included sign-off on the new Enhanced Furnace Safety Module that was implemented in late 2009. The module proved the ability to detect abnormal water, such as snow in the charge bucket and a water panel leak.
The plant has defined and implemented appropriate levels of operator response to its process operation to improve the safe operation of the EAF.
