The Galvanizing Technology Committee (GTC) held a meeting in Independence, Ohio, on 10–11 Mar 2010, with 107 attendees. Stavros Fountoulakis of ArcelorMittal greeted the attendees and reviewed the agenda. Eric Almquist of Star Tool & Die agreed to record the meeting minutes. Dr. Fountoulakis reviewed the AIST Anti-Tust Guidelines, and everyone agreed to abide by them. The final details for the GTC’s AISTech 2010 sessions were reviewed. Brian Lippert of ArcelorMittal gave a safety overview presentation regarding ArcelorMittal Cleveland’s hot-dip galvanizing line (HDGL). He highlighted the company’s personal protection equipment requirements and explained their specific procedures around the galvanizing pot “red zone” and the dross robot. He also explained the “weld approaching” alarms, pre-melt pot measures, and dross-platform configurations. A question-and-answer period followed, with significant discussion. Participants were asked to introduce themselves, their responsibilities and their company. Business cards were collected and are posted on the GTC’s Members Only area of AIST.org. An informal technical program began after the introductions. Each presenter was given 15–20 minutes to introduce a topic, and then 20 minutes were allotted for discussion between the participants and the presenter. The following is an overview of the topics and presentations. All presentations are posted in the Members Only area of the GTC Web site.
Topic 1: Pot Hardware and Peripheral Equipment: Daniel Plaetzer of Band-Zink presented “Zn-Pot Hardware for Automotive Galv Lines: Basic Design.” He overviewed many factors that affect coating performance by explaining appropriate design details of each component. He also provided two case studies for zinc pot hardware. Mr. Plaetzer finished with an outlook on R&D efforts. Kevin Young of Hatch presented “Longer Operating Windows Through Pot Equipment Design.” He gave an overview of some recent advances in pot rig design. He placed special emphasis on rig changes, restarts and automation. Luc Warichet of CMI presented “Three- vs. Two-Roll Hardware Systems.” He discussed the fundamentals and strengths/weaknesses of 2- and 3-roll rigs. His particular emphasis was on long-bow vs. cross-bow, with the importance of knife accuracy and strip flatness. He explained the use of each rig roll to optimize equalization of stresses and yielding within the strip — to minimize cross-bow. He asserted that EM-stabilization alone cannot perfectly correct cross-bow.
Topic 2: Coatings for Pot Hardware: Dennis Green of ASB Industries presented “Thermal Spray Surfacing, Welding and Seal Treatments.” He focused on the process of handling, preparing, applying coatings to, repairing and inspecting zinc-pot rolls. Bill Jarosinski of Praxair presented “Status of Pot Roll Coating Technology.” His presentation focused on the details of different roll coatings and methods to apply them to the rolls. Mr. Lippert briefed the group on the ArcelorMittal Cleveland HDGL and the tour plan. The committee adjourned for the day in order to conduct the line tour.
The second day began with a review of the previous day and questions about snout tips, pot roll coatings, pre-heating rigs/rolls. The technical program then continued as follows:
Topic 3: Pot Bearings/Bushings, Sleeves, End-Caps: Dr. Mark Bright of Pyrotek presented “Dynamics of Journal Bearings on the Stabilizer and Sink Rolls in a Zinc Pot.” He reviewed the fundamentals of failure modes, effects and physics of zinc-pot bushing/bearings. Mark Hall of McDanel Advanced Ceramics presented “Improved Line Performance With Ceramic Bearings — Case Studies.” He reviewed the typical bearing loads per bushing on a 3-roll rig. Dr. N.Y. Tang, of TECK, presented “Sink-Roll Bearings: Lab Evaluation and Field Performance.” He showed process, research and results of their lab-based bearing/bushing test rig.
After the technical program, those interested in AlZn coatings went to a separate room to discuss their specific concerns. About 40 people participated in this 2-hour breakout session regarding >55% Al coatings. There were 30 people interested in the AlZn, and 10 were interested in hardware and other issues regarding aluminized products. After these sessions, a discussion reviewing the meeting and future formats began. There was a consensus that producers will benefit from a producer-only session before and/or after the general meeting. Charles Kay of ASB then gave pre-tour instructions of their facility. The meeting adjourned, followed by lunch, and then about 50% of the participants drove to Barberton, Ohio, and toured ASB Industries.
The next GTC meeting was held 5 May 2010, during AISTech in Pittsburgh, Pa. There was open discussion about topics related to theme of furnaces. Dr. Fountoulakis will compile the list of topics for committee vote in order to establish the program for the GTC’s next meeting 15–16 Sep Toledo/Detroit area (location TBD).
The Galvanizing Technology Committee (GTC) met on 15–16 Sep in Toledo, Ohio. The committee did an excellent job of developing a town hall program for the meeting, with the theme “Cost Reduction Through Zinc Savings.” The meeting had more than 80 attendees. The committee chair, Stavros Fountoulakis of ArcelorMittal, opened the meeting and welcomed the attendees, who then introduced themselves. The AIST Anti-Trust Guidelines were read and agreed upon. Frank Goodwin of the International Zinc Association (IZA), and head of ILZRO, reviewed the status of the abstract selection for AISTech 2010 in Pittsburgh, Pa. The GTC will conduct two sessions, one during the morning and another during the afternoon on Monday, 3 May 2010. The committee agreed to pursue developing other workshops and training seminars. The town hall program began in the afternoon with five presentations on the theme “Zinc Savings Through Operating Practices”: “Zinc Pot Management” by Martin Gagne of Xstrata Zinc Canada, “Product Transitions GA to GI and GI to GA” by Joe McDermid of McMaster University, “Zinc and Aluminum Feeding Practices” by Daniel Liu of Teck Metals Ltd., “Dross Buildup on Pot Rolls” by Nai-Yong Tang of Teck Metals Ltd., and “Top and Bottom Dross Removal” by Mr. Goodwin of ILZRO. Each presentation was followed by open discussion to allow the attendees a chance to ask questions and give insight into their own practices and experiences. The next morning was focused on “Zinc Savings Through Coating Control,” and the four presentations were: “New Developments in Coating Knives” by Ned Kohler of Danieli-Kohler, “Coating Knives and Built-In Electromagnetic Strip Stabilizer” by Mike Sloan of Fontaine Engineering, “Coating Weight Control Optimization” by Jim Hetzer of A.C.T., and “Zinc Savings Without Compromising Quality” by Tim Meakin of Hatch IAS.
