Hot-rolled coils are made of slabs as raw materials, and are made into strips by rough rolling mills and finishing mills after heating.
The hot steel strip from the last rolling mill of the finishing rolling is cooled to the set temperature by laminar flow, and is coiled into a steel coil by the coiler.|

1. Hot rolled coils are made of continuous casting slabs or initial rolled slabs. They are heated in a step-beam heating furnace, descaled with high-pressure water, and then enter the rough rolling mill. The rough rolled material is cut and then enters the finishing mill for computer-controlled rolling. After the final rolling, it is cooled by laminar flow (cooling rate is controlled by computer) and coiled by a coiler to become a straight roll.
2. Cold Rolled Coils Different from hot-rolled coil, cold-rolled coil refers to the steel strip that is directly rolled to a certain thickness by rollers at room temperature and then rolled into a whole roll by a coiler. Compared with hot-rolled coil, cold-rolled coil has a brighter surface and higher finish, but it will produce more internal stress and is often annealed after cold rolling.
3. Galvanized coils are made by dipping thin steel sheets into a molten zinc bath to make a layer of zinc adhere to the surface of the thin steel sheet. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheets are continuously dipped into a molten zinc bath to make galvanized steel sheets; alloyed galvanized steel sheets. This type of steel sheet is also made by hot dip method, but after leaving the bath, it is immediately heated to about 500ºC to form an alloy film of zinc and iron. This type of galvanized coil has good coating adhesion and weldability.
4.Color coated steel coil is a product made of hot-dip galvanized steel sheet, hot-dip aluminum-zinc steel sheet, electro-galvanized steel sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coating are applied on the surface, and then cured by baking. It is named after the colored steel coils coated with various colors of organic coatings, and is referred to as color coated steel coils.
