Data-driven method for setting process parameters of continuous hot-dip galvanizing air-knife

Abstract

The present application relates to a kind of data-driven strip continuous hot-dip galvanizing air knife process parameter setting method, including according to the classification of strip's coating type, coating thickness specification, substrate brand, thickness, width, establish air knife parameter formula, utilize production process historical data to calculate air knife parameter formula data initial value, utilize production process data online optimization air knife parameter formula data;According to actual coating thickness deviation, air knife parameter formula is used to calculate air knife pressure compensation, realizes air knife pressure setting online correction;Data-driven strip continuous hot-dip galvanizing air knife process parameter setting method is used to replace artificial experience setting, realizes artificial experience extraction, storage, optimization, guarantees production process consistency and stability, by reasonably setting air knife process parameter, can effectively prevent zinc flow ripple, air knife streak and edge thickening and other quality defects, will help coating thickness quality and control precision further improve, with good application and promotion prospect.
