Production of Cold Rolled Steel Sheet Coils
Hot-rolled coils are used as feedstock to produce cold-rolled coils. The processing begins by pickling the feedstock in acid and washing on continuous pickling lines to remove scale and impurities from the strip surface.
The coils are then transferred to continuous and reversing cold-rolling mills, where plastic deformation without pre-heating is applied until the cold-rolled coil reaches the customer’s required thickness. The external deformation force causes changes in the structure and, therefore, properties of the steel, which is called cold hardening. The structure of cold-hardened metal is characterised by the predominant orientation of crystals (texture) towards the rolling direction. While cold hardening promotes greater strength and hardness, as well as lower plasticity and viscosity, these properties may differ along the cross section of the coil. Therefore, once discharged from the rolling mill, most merchant cold-rolled coils go through heat treatment, ie annealing, in bell-type furnaces or on continuous lines.
In the final production stage, the annealed cold-rolled coils are transported to coiling, skin-pass and straightening facilities, slitting or cutting machines, followed by inspection, packing and placing the cold-rolled coils in the finished goods storage area to be shipped to customers.
Product Description
Cold rolled steel is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to a specific thickness through a series of rolling stands (tandem mill) or passed back and forth through a reversing rolling mill. The steel can be heated to controlled temperatures (annealing) depending on mechanical property requirements, and final rolled to the desired thickness.
Cold rolled steels are used in many industries and applications, including the automotive industry, light engineering, domestic and electrical appliances, heating and air conditioning equipment, tubes and sections.
