Presentation:

Surface Quality in Cold Rolling Applications – Corrective Action, William Hartley, Quaker Houghton and Liz Abreu, Steel Dynamics Inc. – Flat Roll Group Southwest-Sinton Division

This session will dig further into the identification of specific surface defects at the production line, and trace back to causes that can be addressed upstream or in-line to correct and minimize affected material. Well-trained inspectors and personnel at the line are key to quickly identifying conditions that may affect final product quality. Having a consistent language to describe conditions and communicate quickly and effectively within the team and back to upstream processes or suppliers will improve efficiency of troubleshooting and resolving surface quality concerns. Understanding what information to collect about a defect and how to analyze for effective root cause determination will support better understanding by the team of potential failure points within the process, and drive problem solving for long-term solutions that prevent recurrence. These topics will all be explored in the corrective action webinar.
