Characteristics of stainless steel cold-rolled plate and strip products

The stainless steel cold-rolled production process describes the stainless steel cold-rolled strip product which inherits the high-quality corrosion resistance and process performance of stainless steel grades and expands through its rich surface types and exquisite high-quality process performance. It broadens the connotation of the application of stainless steel plates, thereby expanding the application scope of stainless steel plates, and becomes a widely used structural type in stainless steel plates. It also introduces the application status of stainless steel cold-rolled strips in various civilian manufacturing industries and industrial industries as well as high-standard process performance and performance test plans. The production of stainless steel cold-rolled strips requires more than ten processes. The continuous industrial production process will inevitably cause surface defects. Because of its excellent corrosion resistance, formability, compatibility and strong ductility in a wide temperature range, stainless steel plates are widely used in petrochemical equipment, nuclear energy, light industry, textiles, food, and home decoration. Equipment and other aspects are widely used. Stainless steel cold-rolled strip products inherit the excellent corrosion resistance and process performance of stainless steel. According to different cold-rolled processing methods and surface re-processing after cold-rolling, the stainless steel surface can have different levels of surface. Smoothness, texture and color have become the most commonly used structural types in stainless steel.

Stainless steel plate cold rolled strip production process flow
The hot-rolled stainless steel belt goes through a bell furnace (BAF), hot coil quenching, pickling and passivation (HAPL), and multi-roller reversible Plastic extrusion machine (CRM) or cold continuous extrusion machine (TCM), precision grinding unit (CGL), cold coil quenching, pickling and passivation unit (CAPL) or bright quenching unit (BAL), grinding unit Several systematic generator sets such as (CGL), smoothing machine (SPM) or tension leveling set (TLL) and longitudinal sectioning (STL) or recoiling (RCL) or cross sectioning (CTL) carry out all steps. Characteristics of stainless steel plate cold-rolled strip products

Stainless steel has become a widely used metal composite material due to its excellent corrosion resistance, excellent physical properties and processing characteristics. Through different cold rolling processing methods and surface reprocessing after cold rolling, the surface of the stainless steel plate can have different levels of surface smoothness, texture and color. The surface processing of stainless steel cold-rolled plates includes 3D, 2B, No.3, No.4, 240, 320, No.7, No.8, HL, BA, TR hard, embossed and other surface levels. On the cold-rolled surface, various surface processing processes such as electroplating, chemical polishing, non-directional hair lines, etching, shot blasting, coloring, plating and composition can be carried out. Then heat the pickled and passivated surface and textured plate. The surface of the stainless steel plate can reach more than 20 kinds. This type of rich and colorful surface greatly improves the appearance of the stainless steel plate, enabling it to achieve an aesthetic effect, enhance its appeal to consumers, and provide people with beautiful enjoyment. The different surface processing of stainless steel plates broadens the connotation of stainless steel plate applications, thereby expanding the application scope of stainless steel plates. According to the traffic statistics of the stainless steel technology professional website, China's stainless steel cold-rolled plates accounted for 70% of the total output value of stainless steel in 2013. In addition to the characteristics of the stainless steel grade itself, it is mainly the various surface layers of the stainless steel cold-rolled plates. Caused by the unique influence of types in applications.

Surface production and processing types of stainless steel cold-rolled strips

Stainless steel plate surface processing can be divided into two categories. One is the surface obtained by stainless steel plate manufacturers using different production processes, which is generally called cold-rolled surface processing; the other is for changing the surface grade or properties. , The professional surface processing of rolled materials is generally called the surface processing of stainless steel plates.

The surface processing of stainless steel cold-rolled strips is divided into different surface processing types according to different processing methods. The standards of various countries around the world have set corresponding requirements for the surface production and processing of stainless steel cold-rolled plates. The stainless steel cold-rolled manufacturing industry is generally classified into the surface processing types in Table 1 according to Japanese JIS and British ASTM standards. In addition to the cold-rolled surface processing types of stainless steel plates required in Table 1, there are also embossed surface processing and reticulated steel plates that use hot rolling or plate processing that can be called cold-rolled surface processing.
