Steel Mills

The Best Gearbox, The Fastest Response

Bill Sutton, SMA Sales

One of the largest steel recyclers in the United States, Nucor Steel’s ( sheet mill in Hickman, Arkansas keeps plenty busy--recycling over two million tons of steel each year. With such a large recycling operation, one would expect that Nucor’s management constantly keeps a watchful eye on its machinery to prevent breakdowns. In 2007, as part of a capital project, Nucor upgraded 48 of its tunnel furnace rolls. During this project, due to performance and delivery issues with its former gearbox supplier, Nucor decided to trial 10 gearboxes manufactured by Sumitomo Drive Technologies.

With unclear delivery commitments from its former gearbox supplier and after successful trial runs with Sumitomo gearboxes, Nucor contacted Sumitomo to supply the remaining phase of their project with an additional 35 gearboxes. Within two weeks of facing a standstill in their operations, Sumitomo reassured Nucor that they would receive their order in time. Not only did Nucor receive their extra order of gearboxes, they were delivered in an amazing 5 days! Representative of Nucor, Chris Kovalsky said, “With respect to our issue, I could not be more pleased with the responsiveness Sumitomo displayed. Their gearboxes will be getting installed on the next four phases of this project.”

For over two months Nucor has been using 40 Sumitomo gearboxes in reversing applications under heavy loads, without incident. Now, with the assistance of the Sumitomo Cyclo® 6000, Nucor Steel can continue producing steel sheets without the stress of possible gearbox failure. Once Nucor completes its tunnel furnace upgrades, they will have more than 200 Cyclo units installed in their Arkansas factory. Sumitomo Cyclo 6000 provides both a cost effective and highly efficient gearmotor for Nucor Steel.

The Sumitomo Cyclo 6000 series gearmotors are available from 1/10 to 235 HP and ratios from 3:1 to 658,503:1. The gearmotors are maintenance free, lightweight, compact and very rugged with a two-year warranty guaranteeing exceptional performance.
