What is stainless steel cold rolling
Hot rolled steel coils are used as raw materials, and after acid washing to remove oxide scales, cold continuous rolling is carried out. The finished product is rolled hard coils. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coils increase, and the toughness and plasticity index decrease. Therefore, the stamping performance will deteriorate, and can only be used for parts with simple deformation. Rolling hard coils can be used as raw materials for hot-dip galvanizing plants, as hot-dip galvanizing units are equipped with annealing lines. The weight of the rolled hard coil is generally 6-13.5 tons, and the steel coil is continuously rolled on the hot-rolled pickling coil at room temperature. The inner diameter is 610mm.
Because it has not undergone annealing treatment, its hardness is very high (HRB greater than 90), and its mechanical processing performance is extremely poor. It can only be subjected to simple directional bending processing of less than 90 degrees (perpendicular to the coiling direction). Simply put, cold rolling is the process of processing and rolling on the basis of hot-rolled plates and coils. Generally speaking, it is a process of hot rolling, acid washing, and cold rolling.
Cold rolling is made by processing hot rolled plates at room temperature, although rolling can also cause the steel plate to heat up during the processing, it is still called cold rolling. Cold rolling, which is formed by continuous cold deformation through hot rolling, has poor mechanical properties and high hardness. It must be annealed to restore its mechanical properties. Those without annealing are called rolled hard coils. Rolling hard rolls is generally used to make products that do not require bending or stretching. For thicknesses below 1.0, rolling hard rolls can be used to bend both or all four sides with good luck.
Cold rolling in the industry can also be referred to as cold rolled coils or sheets. The origin of these names is due to the classification of cold rolled products, which are specifically divided into two main categories: cold plate and cold coil. And cold rolled sheet can also be called cold rolled sheet or cold rolled sheet; Cold rolled coil can be referred to as cold rolled coil or cold plate coil. In addition, cold rolling also includes some relatively rare varieties, such as cold rolled box plates, cold rolled hard plates, cold rolled thin plates, etc. These two types are mainly named separately due to their different shapes and materials. Of course, due to different manufacturers producing steel, sometimes the name of the manufacturer is also added to the naming, such as Baosteel cold coil, Tangshan steel cold plate, etc. Cold rolled thin coils can be equated with cold coils, and the interpretation varies depending on the customs in different regions. With the different specifications of cold rolling, it needs to be divided into more detailed categories, which depends on which specifications and models of cold rolled products belong to. For example, SPCC cold rolled coil is the name of a cold rolled coil.
