Hot dip galvanizing (aluminum) line is a set continuous hot dip galvanizing (aluminum) equipments which produce zinc and aluminum coating steel coils mainly used for automobile, household electric appliance, building construction and base plate for color coating and the producing capacity is 250 thousand tons per year. The processes include uncoil, stitcher, pre-cleaning of the strip steel, entry loop, annealing, zinc pot, air knife, cooling tower, skin pass mill, tension leveling, passivating (anti-finger print) , exit loop, coating oil, exit shear, recoil, surface inspecting and so on to achieve multi-function, efficient and continuous production. The line is flexible to process many kinds of products in order to meet the demands of market. Can be customized according to the requirements of customers.
