Hot Dipped Galvanized Steel
Galvanization is a surface processing craft that people galvanize the zinc on the surfaces of metal, alloy or other materials. It make the materials to be nice and anti-rust. Hot dipped galvanized steel is its main products. CAMELSTEEL will introduce the produce process of hot dipped galvanized steel with you.
a. After the alkaline degreasing, washing and drying, the cold and hot rolling steel sheet will be annealed in the horizontal or upright heat furnace which has radiation tube. The hydrogen in the furnace restores the steel.
b. After the heating, the strips are put into zinc liquid and becomes hot galvanization. When it is out of the zinc pot, people will use the gas knife to control its galvanize quantity.
c. The size of spangles is controlled by the ingredient of zinc liquid and coerce refrigerant method. Before the diffuse of spangles, people could use the equipment of small spangle to do the fast refrigerant which could prevent its continuing diffuse, and it forms small spangle.
d. After the refrigerant, the strip will be processed by skin passed. Then it will be processed by surface passivative process or produced into the color coated steel coil directly according to its application.
