Nowadays, the development speed of industrial technology has exceeded our imagination. It seems that every day it seems that there are some innovations. The production of industrial materials has reached a very rapid pace, and a variety of industrial materials have been used in all walks of life in our lives. Today I would like to introduce to you the relevant knowledge of cold-formed steel. The cold-formed steel refers to a variety of shapes of finished steel products that are bent in a cold state using a steel plate. The wide-ranging steel has a wide variety of applications and is a common material for various stages of construction, assembly of load-bearing objects, and the like. It occupies a large part of the market in our production operations. So, do you know what cold-formed steel manufacturers have? Here I will introduce to you the cold-formed steel manufacturers , classification and application! Cold-formed steel profile Cold-formed steel is one of many kinds of steel products. A certain width of strip steel is gradually deformed under a normal temperature condition through a set of longitudinally arranged rolls to meet the required shape and size, and then cut to a corresponding size by the determined size. length. This product is a cold-formed steel. Of course, cold-formed steels can also be obtained by deformation methods such as stamping, bending or drawing. However, the roller bending method is suitable for large-scale industrial production. Its product quality, processing cost, and production efficiency are unmatched by other methods. It is currently the main production technology of cold-formed steel. If the equipment is equipped with welding equipment (such as high-frequency welding, argon arc welding, etc.) can also produce closed-section cold-formed steel. The difference between cold-formed steel and welded steel pipe is mainly: welded steel pipe is mainly used for conveying fluids such as gas and tap water. Petroleum, liquefied gas, steam, etc. The steel pipe is required to withstand a certain pressure, and the cold-formed steel is used to manufacture the structure. Under the external force, there are certain requirements on the section, shape, size and mechanical properties of the steel. Cold-formed steel classification and application 1. The cold-formed steel is classified according to the size specifications, and is divided into large-scale, medium-sized, small-sized, and wide-width four kinds according to the product thickness and expansion width. (1) Large cold-formed steel: product thickness is 6-16mm, product development width 600-2000mm. (2) Medium-sized cold-formed steel: The product thickness is 3-6mm, and the product development width is 200-600mm. (3) Small cold-formed steel: The thickness of the product is 1.5-4mm, and the product development width is 30-200mm. (4) Wide-width cold-formed steel: The product thickness is 0.5-4mm, and the product development width is 700-1600mm. 2. Cold-formed steels are classified according to shapes and can be divided into open and closed categories. (1) Common open cold-formed steels with equilateral and unequal angles, inner and outer crimp angles, equilateral and equilateral channels, inner or outer crimp channels, Z-beams, coils Side Z-shaped steel, special profiled open-type steel and so on. (2) Closed cold-formed steel is a welded, closed-section cold-formed steel, in the shape of a circle, square, rectangle and profile. 3. Cold-formed steel is classified according to its purpose. Different industries have different requirements for cold-formed steel. Cold-formed steel production plants can meet different requirements of various industries and produce various special cold-formed steels. Mainly the following items can be listed. (1) Cold-formed steel for automobile manufacture; Small-size passenger cars, most of which use profiled open-type steel, such as windows, rain gutters, seat pulleys. The majority of passenger cars use square rectangular steel with closed ends, most of them use open-formed cold-formed steels, and special vehicles such as fire engines and construction vehicles use square rectangles and special-shaped cold-formed steels. (2) Railway vehicles: Most passenger cars and freight vehicles use special shaped cold-formed steels, for example, cold-formed sill beams instead of hot-rolled sill beams. For a long time, the mid-beams used in the gondola, wagon and tanker chassis are hot-rolled B-weld welded structures. It uses two high-grade 310 hot-rolled B-shaped steels made by welding, as the middle beam uses hot-rolled steel welded structures. , It has the disadvantages of heavy weight, high welding quality (needs non-destructive testing), numerous processes, and high overall cost. Therefore, the railway department hopes to develop an integrally formed, lightweight, high-strength, high-strength, and highly-efficient cold-formed steel instead of hot-rolled B-welded steel. The cold-formed sill beam developed by Wuhan Iron and Steel Co., Ltd. uses hot-rolled coils as raw materials, and the integrated sill is obtained through continuous molding. Another example: Qiqi Group developed the cold-formed steel for the end wall and the capped steel side column in 1985. In 1993, it developed the cold-formed steel for the side beam of the rectangular pipe with a sharp corner. The material is cold-formed steel 09CuPTiRE-A. The yield strength is 295 MPa. The use of cold-formed steel in railway trucks in China will increase. (3) Elevators: Hollow rails for elevators, structural frames for escalators and cold-formed steels for other special-shaped components (4) Shelf: Cold-formed steel for small supermarket shelves and large warehouse supermarket shelves. (5) Transmission Tower: The research focuses on the use of cold-formed steel instead of traditional hot-rolled angle steel to improve the overall performance of the tower and reduce costs. In high-voltage long-distance transmission towers, high-strength corrosion-resistant structural steel pipes have been tested in various places. The triangular iron tower structure made of cold-formed steel in the communications tower is also under development. (6) Construction machinery: crane lift arm, support arm, cold-formed steel for tower crane frame (7) Electrical equipment manufacturing industry: electrical cabinets, cold-formed steel for cable trays (8) Agricultural machinery: cold-formed steel for tractors, ploughs, rakes and harvesters, and cold-formed steel for agricultural framing. (9) Construction industry: Maintenance structure of steel structures (beams, columns), roofs, walls, doors and windows, cold-formed steel for installation. (10) Furniture: Stools, chairs, cupboards, beds, etc. are special cold-formed steels. Wherever steel is used, cold-formed steel can be used. Cold-formed steel main features Cold-formed steel is a section steel of various cross-sectional shapes made by hot-rolled or cold-rolled strip steel as billets. Cold-formed steel has the following characteristics: 1. The section is economically reasonable and saves material. The cross-section shape of the cold-formed steel can be designed according to the needs, the structure is reasonable, and the section coefficient per unit weight is higher than that of the hot-rolled section steel. Under the same load, the weight of the components can be reduced and materials can be saved. Cold-formed steel is used to save 38-50% of the metal in comparable architectural hot-rolled steel structures and 15-60% in metal for agricultural machinery and vehicles. Facilitate construction and reduce overall costs. 2. With a wide variety of products, it is possible to produce a wide variety of sections and various types of cold-formed steel with uniform wall thickness and complex cross-section shapes that are difficult to produce by ordinary hot rolling methods. 3. The product surface is smooth and clean, the appearance is good, the size is accurate, and the length can also be flexibly adjusted according to the need. All products are supplied according to a fixed length or multiple feet to improve the utilization of the material. 4. Production can also be combined with punching and other processes to meet different needs. Cold-formed steel manufacturers Jiangyin Jianhao Steel Products Co., Ltd.
