Product Usage

It has a wide range of uses, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc. Cold-rolled sheet steel is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also called cold-rolled sheet, commonly known as cold-rolled sheet, and sometimes it is mistakenly written as cold-rolled sheet. The cold plate is a hot-rolled strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Because rolling at room temperature does not produce iron scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled thin steel plates. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets.

Cold-rolled ordinary thin steel plate: cold-rolled from ordinary carbon structural steel or low-alloy structural steel. The surface quality of the cold-rolled sheet is better. Has good stamping performance. It is required to ensure that the cold bending and cup tests are qualified, and it is often used in the automotive industry and the raw material of the plated plate.

Cold-rolled high-quality thin steel sheet: mainly includes various high-quality steel cold-rolled sheets, the most commonly used is carbon structural steel plates, especially cold-rolled thin steel sheets for deep drawing, which are cold-rolled sheets of low-carbon high-quality steel 08Al. The quality is divided into three groups; Ⅰ, Ⅱ, and Ⅲ, respectively represent the special high-level, high-level, higher finishing surface, according to the drawing level is divided into ZF, HF, F level (representing the most complicated and very Complicated and complicated parts). According to the allowable deviation of the thickness of the steel plate, it is divided into two levels of accuracy, A and B, and is widely used in the automobile and tractor industry.

Cold-rolled steel sheet: Smooth surface, excellent processing, used in home appliances such as automobiles, refrigerators, washing machines, industrial equipment, and various building materials. With economic development, cold-rolled steel sheet has been called an essential material in modern society. Classification of cold-rolled products: hot-rolled pickling, hard-rolled coils, ordinary cold-rolled, galvanized (electro-galvanized, fingerprint-resistant, hot-dip galvanized), galvanized, electro-tinned, color coated, electrical steel (silicon steel sheet) Wait.

Hot rolled pickling:

Rolling hard coil: continuous rolling of hot-rolled pickled coils at room temperature

Features

Because it has not been annealed, its hardness is very high (HRB is greater than 90), and its machining performance is extremely poor. It can only be used for simple directional bending processing (perpendicular to the coiling direction) of less than 90 degrees.
