Abstract

A numerical simulation of airflow was conducted during the application of a protective zinc coating with air knife blowing. The simulation was conducted in combination with the air knife features on the hot-dip galvanizing line of the cold rolling mill of Shougang Jingtang United Iron & Steel Co., Ltd. Fluent software was used in the simulation. This study also analyzed the effects of process parameters, such as air pressure, air blowing range, knife openness, and angle, on coating thickness. The effects of various factors on the numerical simulation of air pressure on the strip surface were regressed into a mathematical model. This method facilitated the quantitative analysis of such factors and provided a theoretical basis for precisely controlling coating thickness on the site.
