Cold rolling can also be called cold-rolled coils and cold-rolled coils in the industry. The origin of these names is because of the classification of cold rolled products. Cold rolling is divided into two main categories: cold plates and cold coils. Cold plates can also be called cold-rolled plates and cold-rolled plates; cold coils can be called cold-rolled coils and cold plate coils. In addition, cold rolling also includes some relatively small varieties, such as cold-rolled box plates, cold-rolled hard plates, cold-rolled thin plates, etc. These two categories are named separately mainly because of their different shapes and materials.
Of course, since there are different manufacturers of steel products, the name of the manufacturer is sometimes added to the name. Cold-rolled thin coils can be equated to cold coils, and the terms vary depending on local customs. As the cold rolling specifications are different, it will be divided into more detailed classifications, which depends on which specification and type of cold rolling product it belongs to. Cold rolling oil plays an important role in the cold rolling process, specifically as lubrication and cooling.
