Abstract

In the last few of years there has been a boom in the steel market that has pushed operations to their design capacity limits and then beyond. Many melt shops equipped with supplementary reactors as part of their equipment are now bypassing them at flat bath as a way to increase melting capacity. Many other shops are reviewing their existing transformer and redefining the operating points, as a way to take advantage of this great opportunity the steel market offers. GrafTech Technical Service personnel have been following many of these installations in North America; coincidental with this event we have developed new EAF monitoring equipment that has been instrumental in quickly determining the optimum operating settings for the EAF from the stand point of the electrical parameters. This paper will cover some of the latest examples involving cooperative and coordinated efforts to solve specific critical situations related to the EAF operation and the optimum use of melting power in a North American melt shop.
