What are the characteristics of galvanized coil

The biggest reason why galvanized sheet is welcomed by the market is its economy. Compared with other steels, galvanized sheet has good anti-corrosion effect and high application value. Its application range is very common. The world's zinc production is generally used to process galvanized sheet. Due to its high market recognition, the demand for galvanized sheet is also particularly large.

Is the galvanized coil resistant to high temperature?

The melting point of zinc is 419.5 ° C, and the 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 ° C, zinc oxidizes violently, showing white zinc oxide. After high temperature grilling, the material of the anti-corrosion layer on the surface of the galvanized sheet is oxidized, so the galvanized sheet cannot withstand high temperature, and the surface will change color when heated, or other substances with protective properties on the surface will easily turn yellow after oxidation.

Process flow of galvanized coil

The cold-rolled steel plate is degreased by alkali washing and washed with water. After drying, it enters a horizontal (vertical) heating furnace heated by a radiation tube for annealing. A certain amount of hydrogen gas is introduced into the furnace to reduce the atmosphere in the early layer of the furnace.

Classification and process of galvanized coils

The galvanized coil immerses the thin steel plate in the molten zinc bath, and a layer of zinc is attached to the surface of the thin steel plate. At present, it is mainly consumed through the continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the galvanized tank of zinc condensation to consume galvanized steel plate.

What is the use of steel coil and how to judge the material of steel coil

There are many things that are essential in our daily life. No matter what we want to buy, we must first understand some knowledge. In this case, it will be easy to choose on the surface. Therefore, we can first look at what the steel coil is used for. Only by knowing its purpose can we know where to use this kind of thing, and also look at how to judge the material of the steel coil.
