Process flow of galvanized coil

Cold and hot rolled steel plate through alkali wash degreasing, and washing, drying and then into the horizontal (vertical) heating furnace with radiant tube heating for annealing, the furnace through a certain amount of hydrogen to make the furnace early layer of reducing atmosphere.

1, Cold and hot rolled steel plate through alkali wash degreasing, and washing, drying and then into the horizontal (vertical) heating furnace with radiant tube heating for annealing, the furnace through a certain amount of hydrogen to make the furnace early layer of reducing atmosphere.

2, Heated to a certain temperature of the steel strip under certain conditions immersed in the zinc solution for hot-dip galvanizing.

3, The size of the zinc flower has liquid zinc composition to control at the same time, the use of forced cooling method to control, small zinc flower products in the zinc flower began to diffuse before the small zinc flower equipment for rapid cooling to prevent the zinc liquid to continue to diffuse, the formation of small zinc flower.

4, After hot-dip galvanized pending post cooling through the surface finishing, and finally according to the use, respectively, the surface passivation treatment or direct production into color coated coil.
