Alloy, composite galvanized coil This is an alloy made of zinc and other metals such as lead, zinc, etc. It is even a composite steel plate galvanized pipe steel plate not only has excellent rust resistance, but also has good coating performance.
① The galvanized coil immerses the steel sheet in the molten zinc bath, and attaches a layer of zinc on the surface of the steel sheet. At present, the galvanized steel sheet is mainly consumed through the continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in the zinc condensation galvanizing tank to consume the galvanized steel sheet.
② Alloy galvanized plate bender This kind of steel plate is also hot dipped, but it is heated to about 500 ℃ immediately after coming out of the tank. The alloy coated galvanized plate that forms zinc and iron has good coating adhesion and weldability.
③ The processing performance of galvanized steel sheet consumed by galvanizing coil electroplating is good. However, the coating of galvanized pipe is thinner than that of hot-dip galvanized sheet, and the corrosion resistance is also poor.
④ Single side galvanized coil and double side differential galvanized coil Single side galvanized steel sheet, that is, single side galvanized product has better compliance than double side galvanized sheet in welding, coating, rust prevention treatment, processing, etc. In order to restrain the defect that one side is not galvanized, the other side is coated with a thin layer of galvanized sheet, that is, double-sided differential galvanized sheet.
⑤ Alloy, composite galvanized coil This is an alloy made of zinc and other metals such as lead, zinc, etc. It is even a composite steel plate galvanized pipe steel plate not only has excellent rust resistance, but also has good coating performance.

The steel raw material market is stable. The market is stable in the later period.
Pig iron market prices have not changed, demand is still not good, poor transactions, manufacturers inventory differences. It is understood that there is still no substantial improvement in downstream demand. Downstream steel mills are cautious about purchasing pig iron for steelmaking. Some steel mills temporarily stop external procurement.

Film Forming Mechanism of Color Coated Steel Coil
Non transformative. Generally, it refers to the physical film forming method, that is, it mainly depends on the volatilization of solvent or other dispersion medium in the film, and the film viscosity gradually increases to form a solid film. For example: acrylic paint, chlorinated rubber paint, ethylene paint, etc.

How to distinguish the quality of color coated steel coil
Observe the edge leakage of the color steel plate: when taking the color steel plate, observe whether there are fine, gray, black and impurity crystals in the exposed steel plate, such as the section. If the cutting surface is crystal clear, the quality will be better.

Storage time and inspection items of galvanized steel coil
If it is stored for a long time, it is recommended to simply check and clean it every week. If there is a certain amount of dust accumulation, it should be cleaned in time. In addition, problems such as deformation and collision should be handled in time.

What are the common problems in the production and transportation of color coated rolls
The S roll is scratched and the water cooling squeezing effect is not good. The water is brought into the S roll. The difference between the furnace body tension and the outlet looper tension is too large, which constitutes the S roll slipping.
