Ⅳ.Technological process
1. Hot dip galvanizing technological process

2. Fully automatic operation process action

2.1 operating manual crane to loading position,and manually hang in group, signal when completion;

2.2 pre-treatment full automatic roller galvanizing equipment lift workpiece into degreasing tank, rinsing tank, acid tank and fluxing tank successively, then put into unloading area;

2.3workiece in unloading area enter into loading basket after be leaded into drying passage by auxiliary material, workpiece is lifted by unloading machine into zinc liquid;

2.4 immersing into zinc liquid through immersing zinc system, lifted by centrifuge and centrifuge after satisfy immersing time and then move to unloading area;

2.5 pour workpiece into blasting zinc, cooling and passivation;
2.6 finally pour into discharge conveyor belt, storage after testing.

Ⅴ.Production line basic equipment, performance and parameters

1)Automatic running transmission system

1. The equipment performance and component configuration
