Cold Roll Forming Machine steel (cold-formed steel) refers to the cold plate or strip bent into a variety of state sectional shape of the finished steel. Cold Roll Forming Machine steel is an economical lightweight thin-walled steel cross-section, also called cold-formed steel cold-formed profiles or profiles. Light steel cold-formed steel is the production of primary materials. It can not be produced by a variety of hot-rolled special thin sections and complex shapes and reasonable. Compared with hot-rolled steel in the same case of cross-sectional area, radius of gyration can be increased 50 to 60%, moment of inertia can be increased from 0.5 to 3.0 times, which can be a more reasonable use of the material strength; and ordinary steel ( that is, from the traditional I-beam, channel steel, angle steel and steel production) compared to savings of 30 to 50% of steel.
Cold Roll Forming Machine steel has the following characteristics:
1. Section of economic rationality, material savings. Cold Roll Forming Machine steel cross-section shape can be designed, reasonable structure, unit weight coefficient is higher than hot-rolled steel sections. In the same load, reduce component weight, save material. Than cold-formed steel hot-rolled steel for building structures of metal 38-50% savings for agricultural machinery and vehicles can save 15-60% of metal. Facilitate construction, reduce overall costs. ,
2. Variety, can be produced using methods generally difficult to produce hot-rolled uniform wall thickness, cross-sectional shape of the complex variety of profiles and a variety of cold-formed steel material.
3. Products, smooth surface, good appearance, size, accuracy, and length can be flexibly adjusted according to need, all supplied by length or double length, improve material utilization.
4. Production processes can also be matched with the punch, to meet different needs.
5. Gradually continuous deformation, suitable for mass production.
6. High-quality hot-rolled and cold rolled strip steel, through the continuous roll forming, you can still maintain its excellent surface quality and precise dimensions.
7. Different movements of the cold-formed steel unit and the different parameters of the forming units, for the production of various specifications, various cross section shapes of products to provide a technical guarantee.
8. And other processing equipment with each other, can be complex processing, production of composite profiles.
9. As the processing is usually carried out at room temperature below, so you can strip the coating with a variety of processing, and that does not damage the coating and the coating from the surface.
10. Cold forming can produce complex general difficult to produce hot-rolled sections, types of thin-walled sections, which consumed at least in the case of the metal, the strong maximum rigidity.
11. In large-scale production, the cost of forming rollers less than the die, and die much longer than life.
Cold Roll Forming Machine steel rolling process equipment
Wide variety of cold-formed steel, from the sub-section shape, with open, semi closed and closed, the main products are cold-formed channel steel, angle steel, Z section steel, cold-formed corrugated steel, square tube, rectangular tube, welded tube shaped, shutter doors and so on. Usually produced by cold-formed steel, the thickness of 6mm below the width of 500mm or less. Our products are widely used in mining, construction, agricultural machinery, transportation, bridges, petrochemical, light industry, electronics and other industries.
Production of cold-formed steel is the main material of light steel structure, the use made of steel or steel roll forming. It can be produced not only a very thin wall thickness, but also greatly simplifies the production process, improve production efficiency. With the general method can produce hot-rolled production of uniform thickness is difficult, but a variety of complex cross section shapes and different profiles of cold-formed steel material. Except for a variety of cold-formed steel structures, but also widely used in vehicle manufacturing, agricultural machinery and so on. Many varieties of cold-formed steel, according to sub-section open, semi-closed, closed. By the shape of cold-formed channel, angle steel, Z section steel, square tube, rectangular tube, Special Pipes, shutter doors. According to GB6725-92 provides cold-formed steel structure of the ordinary carbon negative, high-quality carbon structural steel, low alloy steel plates or steel cold-formed steel. Cold Roll Forming Machine steel is an economic cross-section of steel, but also energy efficient materials, is a new type of steel with a variety of great vitality, it is widely used in various areas of the country out of economic, its use can be divided into road divider plate around, steel, automobiles, container, steel formwork and scaffolding, railway vehicles, ships and bridges, steel sheet pile, transmission tower, etc. 10 other categories.
