Cold rolled C-shaped steel is a common type of C-shaped steel in the production process of C-shaped steel. C-shaped steel is automatically processed and formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the forming process of C-shaped steel based on the given C-shaped steel size. Below, Jinan C-beam Steel Factory will explain more product information to you:
According to the shape of the section, steel sections are divided into simple section steel and complex section steel. Cold formed steel refers to finished steel products with various cross-sectional shapes formed by bending steel plates or strips in a cold state. Cold formed steel is an economical lightweight thin-walled steel, also known as steel cold formed profiles or cold formed profiles. In order to apply cold-rolled C-shaped steel reasonably, let's introduce the characteristics of cold-rolled C-shaped steel:
Cold rolled C-section steel is a cold continuous rolling process that uses hot-rolled steel coils as raw materials and removes oxide scales through acid washing. 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 at room temperature for hot-rolled pickling coil steel, with an inner diameter of 610mm.
Product characteristics: Due to the lack of annealing treatment, its hardness is very high (HRB greater than 90), and its mechanical processing performance is extremely poor. It can only be easily bent and processed with a directional angle of less than 90 degrees (perpendicular to the coiling direction) for the section steel.
Simply put, cold-rolled C-beam steel is processed and rolled on the basis of hot-rolled plates and coils. Generally speaking, it is a processing process such as hot-rolling, pickling, and cold-rolled C-beam steel.
Cold-rolled C-beams are made from hot-rolled sheets at room temperature, although they are called cold-rolled C-beams, even if they are heated during the rolling process. Due to continuous cold deformation, the mechanical properties of hot-rolled and cold-rolled C-section steel are poor, and the hardness is too high. It must be annealed to restore its mechanical properties, without annealing the so-called rolled hard coil. Rolling coils are typically used to manufacture products that do not require bending or stretching. If there's anything else, come to our website http://szhongmu.com consulting service
