Abstract:A water model test was carried out to simulate the flow field of an aluminium zinc plated zinc pot in a steel plant. The results show that the flow field of the main zinc pot is influenced by the steel belt drawing speed. In the case of steel belt movement, the fluid in the zinc pot shows obvious stratification and the zinc pot fluid mixing time has significant difference. By contrast,the experiment shows that the drawing speed plays a major impact on mixing time. When the drawing speed reaches 140 m/min, the flow field has the best effect. Through the simulation of stirring experiments, the changes of zinc pot field is influenced by the drawing speed and stirring interaction. According to the experimental results, under the action of stirring, the steel band drawing speed ranges from 120 m/min to 140 m/min, and the mixing time of the flow field is shortened from 25% to 35%.
