Carbon steel coil is made from slabs (mainly continuous cast slabs), which are heated and then made into strips by roughing and finishing mills. The hot steel strip from the last finishing mill is cooled to the set temperature by laminar flow and rolled into coils by a coiler. The cooling coils are processed into steel sheets, flat coils, and slit strip products through different finishing lines according to the different needs of customers.
