12th International Conference on Zinc & Zinc Alloy Coated Steel Sheet - GALVATECH Highlight Symposium 2022

In order to make sure the reliability/accuracy of the snout pyrometer (multiwavelength) for various steel grades (e.g. DP600, DP780 and DP980 etc.) and to monitor the deterioration of the pyrometer due to Zn dust buildup or other causes, predictive models were developed for #5CGL, ArcelorMittal Dofasco. Two approaches (a regression method based on rapid cool wedge-pyrometer readings, and a Zn bath thermal balance method based on Zn pot thermocouples readings) were developed and compared. Based on model evaluation, the snout pyrometer generally provides a reliable measurement, including for DP grades.

Best Paper Winner Weimin Zhong, ArcelorMittal Dofasco, will present highlights from his Galvatech 2021 paper "Snout Temperature Predictive Model and Zn Pot Thermal Balance". Selected highlights from other Galvatech 2021 papers on advances in bath management, pot hardware and coating formation will also be summarized.

Each session will start with the 20 minute lecture, followed by a 20 minute panel discussion. This will be followed by 10 minutes of general discussion and a short break before beginning the next session.
