Steel Coil Manufacturing Process

The steel coil manufacturing process begins with iron and steelmaking, undergoes continuous casting to form billets, and then undergoes hot or cold rolling to form coils. Finally, processes such as annealing, pickling, coating, annealing, and coiling are performed. The specific process depends on the type of final product. For example, hot-rolled coils primarily undergo heating, rough rolling, finish rolling, and coiling; cold-rolled coils undergo further processes such as pickling, annealing, and coiling, and may also undergo galvanizing or other surface treatments.
