Main Production Process Of Gi Steel Coil
Total Articles: 43
1. Uncoiling and welding
Take uncoiling for coiling steel, show the continuous operation needs galvanized coils, conduct electric welding for the belt tail of the former galvanized coils and the lead of the later galvanized coils to ensure the continuous production of the unit.
2. Deoiling and cleaning
Cleaning section is kept clear of GI steel coil with spangles made in china surface, remove the rolling oil and zinc powder, in order to get good coating adhesion and surface quality, usually contains spray, scrub, electrolytic cleaning, brushing, spraying, drying and hot air drying facilities, cleaning section for hot-dip galvanized is more important, is the main process to obtain good galvanized volumes process performance.
Recrystallization annealing is carried out on the hard rolled GI steel coils to obtain excellent mechanical properties of the products. According to the atmosphere in the furnace, good properties of galvanized coils are obtained. The annealing furnace is generally composed of preheating, heating, soaking, cooling, and other sections.
4. Air knife zinc layer control
According to the zinc pot out of GI steel coil with spangles surface spray liquid, usually air or pure nitrogen, to control the galvanized coil surface coating thickness.
5. Fine grain strengthening treatment
Fine grain strengthening treatment is also the process of heating the GI steel coil after galvanized iron sheet to obtain zinc-ferroalloy coating
6. Leveling and pulling the correction
To roll galvanized coils with small rolling force, to remove the compromised platform of high carbon steel, to improve the characteristics of GI steel coils, to get the desired roughness of galvanized coils, to improve the shape of strip steel, to obtain excellent flatness and so on. After leveling is the tension correction, tension correction is to carry out the stretch of galvanized coil straightening, the most important is to get a good shape.
Passivation or other chemical surface treatment of galvanized coils to obtain corrosion resistance, lubrication or other requirements expected by customers, usually by spray extrusion or roller coating drying.
8. The downside
According to the requirements of the galvanized coil to carry out trimming, in order to obtain the appropriate width precision.
The GI steel coil with spangles made in China is coated with oil to obtain certain rust - proof and lubrication properties.
