Application of Cold Bending Steel

Railway vehicles
It uses high-strength weathering steel and the expansion of using cold bending steel. According to foreign data, the railway vehicles used by the cold bending steel has 67 kinds, each section of the truck consumption of 4.7 tons, which occupies 20% of the weight of the carriage. In China, there are 18 to 20 varieties, and 1.2 tons per carriage, which account for 5.2% of the weight of the car. Every vehicle plant should enlarge the use of cold bending steel in the design, and make full use of the characteristics of light, thin-walled and high efficiency of cold bending steel.

Transmission tower
It focuses on studying the use of cold bending steel instead of the traditional hot-rolled angle steel, improving the overall performance of the tower, and reducing costs. In the high-voltage long distance transmission tower, high strength corrosion-resistant structural steel pipe has been testing in Dalian, Guangzhou, Wuxi, Shanghai and other places, and the application of promotion will be held soon. Communications tower, which structure of the triangular tower made of cold bending steel is also being developed.

Steel sheet pile
The application of steel sheet pile is very common in foreign countries, and it is mainly used for river and seaside embankment, construction foundation and trench construction. However, China has neither product standard nor construction specification, so it is impossible to apply the cold bending steel, which is now replaced by hot-rolled channel steel and i-steel. Thus, the next step will be to compile construction specifications by the user industry to fill the gap in the Chinese steel sheet pile market.

Machinery manufacturing
Cold bending steel has great market potential in the mechanical manufacturing industry, especially in automobile manufacturing, but there are not many varieties developed in China, for example, Carriage board, bus keel, car doors and windows, transmission shaft, exhaust pipe, shock absorber, truck girder, etc., as well as bumper, car on all kinds of bends, have not used cold bending steel.

The steel structure
The steel structure is the biggest user of cold bending steel, its application scope is the load-bearing skeleton of the building, the enclosure piece steel cross-section and truss purlin, monomer components, for example: Truss, steel frame, wall frame, support platform, staircases, keel, doors and windows. Cold bending steel is widely used in foreign construction industry, because it is a lightweight thin-walled steel, with lightweight, high strength and excellent performance, and it is also a new material of high efficiency and economy promoted by the country. In developed countries, the steel structure construction used in cold bending steel accounts for 50%~70% of the total amount of cold bending steel. Cold bending steel in the housing steel structure is mainly used in three aspect: to do the skeleton of the column, monomer component and enclosure plate.

Skeleton column
The load-bearing structure steel pipe is the best column of steel structure, its variety has round tube: φ21.3-610mm,t=1.2-1.6mm, 82 standard specifications. Square Tube: 20x20-500x500mm, t=1.2-16mm, 101 standard specifications. Rectangular tube: 30x20-600x400mm, t=1.5-16mm, 170 standard specifications. According to the national standard, there are 353 specifications.

Single component, purlin, roof truss these other openings cold bending steel
The specification of groove steel (with inner winding edge groove steel, outer winding edge groove steel, unequal edge groove steel) is 20×10-400×50mm, t=1.5-6mm, 88 standard specifications. The specification of angle steel (including unequal corners, inner coil steel) is 20x20-150x75mm, t=1.2-6mm, 45 standard specifications.The specification of I - beam (with inner winding edge, asymmetrical I-beam) is 80×40-250×75, t=2-5mm, 23 standard specifications. According to the national standard, cold bending steel used for steel structure of the open steel has 173 specifications. In 2002, the steel amounts were 440 000 tons, which would reach 105 million tons in 2005.

Enclosure Plates
Such as pressure plate, sandwich board, composite plate, tile edge plate, curved plate, etc. Width B=400-1000mm (non-standard width up to 1250mm), t=0.5-23mm, Height H=12-75mm (non-standard height up to 145mm), 129 standard specifications.
