Finishing Rolling Mill for Galvanizing Line
1. Finishing rolling mill function
1.1 It improves the flatness and flatness of the strip, and can also flatten the zinc particles on the surface, making the surface of the strip smooth, which is especially beneficial for deep drawing and other high quality.
1.2 The use of the whole roller, through EDM or laser hairy treatment, has a certain degree of roughness on the galvanized surface of the whole machine. It can improve the adhesion of the coating, and can also store a certain amount of oil, which is beneficial to the lubrication of the die in the deep drawing process.
1.3 For galvanized coating treatment, while the control surface into small zinc flowers, but small zinc flower can still through the paint layer and exposed, galvanized plate and so for some higher requirements, small zinc flower surface finishing processing can be galvanized get more uniform silver white appearance.
1.4 Through finishing, the yield platform is disappearing or not obvious, and the slip phenomenon can be prevented in the subsequent drawing or deep drawing process.
2. Production line technical paramters
a、Finished mill：φ400/φ650×1450mm；
b、Max force：4000 KN；
c、Mill speed：0～180m/min；
d、Bending：400KN；
e、AGC system pressure：21Mpa
3. Technological advancement
Adopting the advanced four or two rolls system structure, the full hydraulic automatic screw-down adjustment, the plate shape bending roll adjustment.
