Hot dip galvanizing process of MBN11251-CR420LA GI70/70 U steel

Hot-dip galvanizing is an anti-corrosion treatment process that coats the surface of steel products with a zinc layer. Its main steps include: surface treatment, preheating, hot-dip plating, cooling and finishing.

Surface treatment: firstly remove impurities such as oil stains and oxide scales on the surface of steel products to ensure surface smoothness. Chemical methods such as pickling or alkali washing are usually used for surface treatment.

Preheating: Put the surface-treated steel products into the preheating furnace for heating treatment to meet the requirements of hot-dip coating temperature, and at the same time, it can effectively avoid the deformation of products caused by temperature difference stress during hot-dip coating.

Hot-dip galvanizing: The preheated steel products are sent into the hot-dip galvanizing tank through the pulley device for galvanizing. The hot-dip galvanizing tank contains high-temperature zinc liquid. After soaking for a certain period of time, the surface of the steel product will be covered with a solid zinc layer.

Cooling and finishing: steel products after hot-dip plating need to be cooled. It is usually cooled by water immersion or air cooling to restore the product to normal temperature. Finishing is to polish and trim the cooled products to meet the requirements of aesthetics and dimensional accuracy.

The above are the main steps of the hot-dip galvanizing process. Hot-dip galvanizing can effectively improve the anti-corrosion performance of steel products, prolong the service life, and give the products a good appearance.
