Brian Smith and Liz Hunter, Cold Rolling Fundamentals Training Seminar planning co-chairs, detailed the presentations that were to be held at the sold-out Cold Rolling Fundamentals seminar in September.
The following presenters spoke:

  • Mark Zipf of Cold Rolling Technologies Inc. used a historical collection of mill images that have been archived since the original installation in 1965, along with recent equipment performance studies to explain the general nature of the Sendzimir mill equipment, and the specific nature of the machine installed at the NLMK Pennsylvania plant. This led the attendees through the operating characteristics and the precise shape control possibilities inherent in this type of rolling mill before visiting the Sendzimir mill.

  • Will Hartley of Quaker Chemical talked about lubrication differences between a Sendzimir Z-mill and a normal 4-high rolling mill stand, and the two main categories of typical Send­zimir mill lubrication systems. He highlighted some established technical specifications used for the selection of various lubricant products.

In the afternoon, the CSRTC toured the cold rolling operations at NLMK Pennsylvania, featuring a 5-stand dms-Bliss cold mill, and a separate single-stand Waterbury-Farrel Sendzimir Z-mill.
