Rongda Composites
Annual production capacity of 350000 tons of aluminum and zinc, 100000 tons of galvanized sheet and 200000 tons of color coated sheet
Galvanized plate-process flow production process a, cold and hot rolled steel plate is degreased by alkali washing, washed with water, dried and then annealed in a horizontal (vertical) heating furnace heated by radiant tubes, and a certain amount of hydrogen is introduced into the furnace to create a reducing atmosphere in the furnace; B, steel strip heated to a certain temperature is immersed in zinc solution for hot dip galvanizing under certain conditions. After the strip steel immersed in zinc liquid comes out of the zinc pot, the amount of zinc plating is controlled by an air knife. C, the size of zinc flower is controlled by the composition of liquid zinc, and at the same time, the forced cooling method is adopted. Before the zinc flower starts to diffuse, the small zinc flower product is quenched with the small zinc flower equipment to prevent the zinc liquid from continuing to diffuse and form small zinc flower.
