hot dip galvanizing line

We can design the production line according to your requirements. The following data is just for your reference.

1 Process description

1.1 productive technology resume

This line is designed as Sendzimir processing.
After cold rolling strip steel surface was clean through electrolysis cleaning and bake, enter into NOF for annealing and reduction, galvanized in the zinc pot in the sealed atmosphere, blowed by air knife and cooling, and obtain galvanizing steel coil. Under the process of the skin pass mill, tension leveler, passivity/antifinger treatment, oil coating, get finished galvanizing coil.

The main process flow: loading coil-pay-off reel( 1# and 2# pay-off reel in turn) - shear (1# and 2# shear in turn) - welding - electrolytic cleaning and drying - annealing - galvanizing/galvalume - air knife blow -- air cooling - water quenching - skin pass mill(reserved) - tension leveler - passivity - electrostatic oiling (reserved)- shear-coiling - unloading coil - packing.
