Optimization and Improvement on Equipment of Passivation System in CGL2
In response to the wide variety of high-strength structural steel products produced by The No.2 Continuous Galvanized Line of strip cold rolling plant of Tang Steel at Tangshan Iron and Steel Company,it is difficult to control the shape of thin specification cold base galvanized sheets.In addition,the unit has always used spray passivation,which may result in defects such as passivation spots,yellow edges at the edges,incomplete drying,and surface scratches on the strip steel during production.By using fluid kinematics,the number and angle of nozzles in the passivation system were optimized,and a series of optimization modifications were made to the passivation system roller system,edge blowing and other equipment,resulting in a significant improvement in the quality of the plate and strip.
