Steel is a raw material that must be used in the production process of almost all industries. Its production and use are very large. Steel coil is the most common form of shipment of steel products. Among the many steel coils, there are different types. So what are the main types of steel coils? What are the differences in their processes?
Hot-rolled coils are made of slabs as raw materials, and are made into strip steel by rough rolling units and finishing rolling units after heating. The hot steel strip coming out of the last rolling mill of the finishing rolling mill
is cooled to the set temperature by laminar flow, and is rolled into a steel strip coil by a coiler, and the cooled steel strip coil.
Cold-rolled coils are steel strips that are directly rolled into a certain thickness at room temperature and rolled into a whole coil by a coiler. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but they will produce more internal stress and are often annealed after cold rolling.
Galvanized coils are produced by hot-dip galvanizing or electrolytic deposition processes based on hot rolling or cold rolling. Galvanizing refers to a surface treatment technology that coats the surface of metal, alloy or other materials with a layer of zinc for aesthetics and rust prevention. The main method used now is hot-dip galvanizing. The hot-dip galvanizing layer is usually thick enough to resist corrosion without an additional protective coating.
The storage and transportation of steel coils are particularly challenging for the protective performance of packaging. Good packaging can reduce the rust of steel and deliver the product to customers in the most perfect state. But how should we package such a large and heavy steel coil?
