Annealing
Bill Lucas, Fives ST
This session will consider various aspects of steel annealing as it pertains to strip. The reasons for annealing, along with the physical results possible with different thermal cycles, will be covered. Equipment employed along with methods of heating, cooling and strip conditioning will be reviewed in greater detail. A brief discussion of materials used and how they influence equipment lifetime and maintenance is included. Processing atmospheres, equipment control methods and safety considerations are also discussed.

Break

2:30 p.m.

Skinpass/Temper Rolling
Mark Zipf, SMS group Inc.
This presentation provides an overview of skinpass and temper rolling, with an emphasis on “why we are doing this” and “how all this works.” Starting with a study of the material’s yielding and deformation behavior, the strip’s surface structure, and the concepts of profile, shape and flatness, an understanding of the key factors is established, warranting the rolling deformation process and governing its objectives. Next, classical rolling mill arrangements are reviewed, and the discussion examines the force-loaded conditions/reactions occurring within the roll bite (in both the longitudinal and transverse directions), leading to how these actions impart certain transformations of the material’s geometry, surface condition and mechanical properties. The mill’s equipment is then dissected with a focus on the general arrangement and roll gap/shape actuators, combined with the mill’s control strategies and systems. Methods of performance measurement/quality evaluation are introduced, along with an examination of problems and shortcomings that are often experienced. The presentation closes with a comparison of differing mill formats and a review of recent developments in enhanced quality and productivity.

The Chemical Process of Steel Strip Cleaning and How to Enhance Performance
Stephanie Williamson, Quaker Houghton
Steel strip undergoes cleaning for the removal of process fluids, metal fines and surface residue prior to various downstream processing and finishing applications. A clean metal surface is necessary for these applications, which include annealing, metallic coating and painting. Before enhancing cleaning performance, it’s important for operating personnel to understand the general framework for chemical and mechanical strip cleaning. Once this general framework is learned, ways to optimize cleaner performance through solution chemistry control and equipment design will be discussed.
