About the Cover

Steelmaking Dust Collector Three-piece Auger Conversion to One-Piece: A Way to Save on Environmental and Maintenance Costs
Rick Bradford, consultant, Performance Improvement Inc. (formerly of Hamilton Steel, Hamilton, Ont., Canada) (rbradford@nas.net)

This project won the AIST Maintenance Processes Operating Committee’s 2006 Bronze Reliability Achievement Award, which  recognizes iron and steel producing companies for reliability improvements and achievements.

Reliability issues recently limited the number of precipitator units available at Hamilton Steel, in turn affecting the plant’s production. The overall reliability program is discussed, with emphasis on the improvements made to the dust removal system.

Getting the Best of Both Worlds in Reversing Mill Recoilers at Nucor Steel–Berkeley
Jason B. Curtis, meltshop mechanical supervisor, Nucor Steel–Berkeley, Huger, S.C. (curtisj@nucorsteel.com); Charles P. Bender (pictured), senior application engineer, NSK Corp., Ann Arbor, Mich. (benderc@nsk-corp.com); and Steven J. Matovic, manager — drives and services, Horsburgh & Scott, Cleveland, Ohio (sjm@horsburgh-scott.com)

This project won the AIST Maintenance Processes Operating Committee’s 2006 Gold Reliability Achievement Award, which  recognizes iron and steel producing companies for reliability improvements and achievements.

In a recent equipment upgrade, parts from two cold mill coilers at Nucor Steel–Berkeley were combined to form a highly productive hybrid machine. This paper discusses the adaptation process and the productivity gains that resulted.

Roll and Overlay Technologies to Improve Operational Performance

This project won the AIST Maintenance Processes Operating Committee’s 2006 Silver Reliability Achievement Award, which  recognizes iron and steel producing companies for reliability improvements and achievements.

The combined technologies of three-dimensional laser technology and strand condition monitors provide the information and data to effectively monitor
and maintain caster alignment to manufacturer’s specifications.
