GI сталеві котушки сплаву покриття

СередGI Сталева котушка varieties, the alloyed galvanized sheet developed after plating through thermal diffusion treatment. As a result, the corrosion resistance is more than twice that of the ordinary hot-dip galvanized sheet. In addition, this kind of alloying treatment can eliminate the spangle on the surface of the coating; At the same time, the evaporation of zinc during spot welding is reduced, and the degree of contamination of the copper electrode of the spot welding machine by zinc vapor is reduced, thereby increasing the life of the electrode. Furthermore, to ensure the excellent adhesion of the coating of the alloyed galvanized sheet, the thicker alloyed galvanized sheet for the outer panel of the automobile adopts efficient heating and cooling measures (high-efficiency burner or induction heater). Furthermore, it is equipped with various alloyed sensors through instrument analysis. Computer instructions adjust the corresponding structure in the coating in time to produce suitable for high stamping deformation requirements.
