Hot galvanizing of steel originally refers to hot dip galvanizing of steel, but with the development of hot plating technology, its concept has gone far beyond the original scope. First of all, people studied the metal into the action after galvanizing liquid, and added a small amount of Pb in liquid zinc, Sb to get the surface has a beautiful crystal pattern, so as to establish the traditional hot galvanizing technology. In order to prevent the oxidation of the zinc solution and obtain a beautiful surface, 0.01% to 0.05% aluminum was added to the zinc solution. Later in order to improve the adhesion of zinc coating and processing performance, added 0.15% to 0.2% in the liquid zinc aluminum, which changes the composition and structure of the galvanized layer, not only improved the galvanized layer, adhesion, also reduced the zinc oxide on the surface of the liquid at the same time. In order to obtain better resistance to atmospheric corrosion, in comparison· products with stronger antioxidant capacity under high humidity gradually showed aluminum content of 5% after the 1960s.
55% and 5% to 30% of some galvanized aluminum products.Galvanized steel production process is based on the development of the development of the theory of hot dip galvanized, steel plate production rolling technology development and the improvement of social and economic requirements of the steel plate and so on, on the basis of multiple thin plate production experienced a hot pack rolling, cold rolling stage, in the production of cold rolling plate also have a bell type annealing furnace and continuous bright annealing, cold rolled steel composition is also varied. Therefore, as a follow-up process of cold rolling, the production process of hot galvanizing is developing correspondingly, so there is a corresponding process of hot galvanizing of steel plate.The creation and existence of.
