Whether the galvanized coil is resistant to high temperature

The melting point of zinc is 419.5 ℃, and its chemical properties are vivid. In the air at room temperature, a thin and dense basic zinc carbonate film is formed on the surface, which can prevent further oxidation. When the temperature reaches 225 ℃, the zinc is oxidized violently, showing white zinc oxide. After high-temperature barbecue, the anti-corrosion layer on the outer surface of the galvanized sheet is oxidized, so the galvanized sheet cannot be resistant to high temperature, the outer surface will change color when heated, or other protective substances on the outer surface will easily turn yellow after oxidation.

Process flow of galvanized coil

The cold and hot rolled steel plate is degreased by alkali washing, washed with water, dried and then annealed in a horizontal (vertical) heating furnace with radiant tube heating. A certain amount of hydrogen is introduced into the furnace to make the early layer reduction atmosphere in the furnace.
