| Steel pipe in the new energy automotive industry cited concern about the future | | admin：admin issue：2012/11/20 8:22:24 cake：3854 | Automotive welded steel pipe is one of the most important species in the precision welded pipe. Automobile major varieties of welded steel pipe for automotive transmission pipe, car muffler Used for pipe, auto condenser pipe, automobile exhaust pipe, and automotive operating shaft tube, the the car thrust tube, automobile shock absorber oil storage tubes. Automobile axle casing seamless steel pipe (GB3088-82) manufacturing automobile axle casing and the drive axle housing axle tubes with high quality carbon structural steel and alloy structural steel hot-rolled seamless steel tubes.
In addition, the application of stainless steel pipe in the car a lot. Stainless steel pipes are mainly used in automotive exhaust systems, accounting for more than 1/2 of the total amount of automotive stainless, 80% of ferritic stainless steel. Automotive engine exhaust gas generated by the exhaust gas intake pipe, front pipe, hose, the converter, the central tube final outflow from the muffler. The exhaust system commonly used steel 409L, 436L, etc.. The car muffler major use of stainless steel welded pipe. It is estimated that the car used in stainless steel pipe the entire downstream users accounted for about 1.5% of the amount of stainless steel pipe, stainless steel seamless and welded pipe use ratio is about 2:1.
In addition, cantilever rack tube for chassis rear axle, chassis front axle assembly with steel pipe sleeve pipe, bearing sleeve, the brake treadle Order of the tube. Cooling air conditioning system with tube cooling water pipes, air conditioning pipes, pipe sensor. Steering shock absorber with the special requirements of the steel pipe cylinder steel tubes, liquid storage cylinder with steel pipe. The hollow shaft tube for the transmission system. The seat tube is mainly used for the seat frame. Ultra high strength steel for the side door bumper. Visible, the pipe in the car wide.
Automotive high-strength fasteners made of stainless steel seamless steel pipe. According to insiders, automotive equipment products, fasteners are one of the key auto parts, passenger car (vehicle) fasteners average amount of about 37 kg. China's car less than 25% of the domestic supply of high-strength fasteners, the majority from the foreign buyers. At present, Baosteel and other domestic enterprises optimistic about the market, is committed to the development of stainless steel seamless pipe. According to industry analysts, in 2012, China's automobile production and sales momentum is expected to be better than 2011, vehicle growth rate of 5%. The amount of consumption of steel products for the automotive industry in 2012 is expected to reach 44 million tons (40 million tons in 2011), in which steel pipe about 80 million tons.
The hybrid system in the next period of time, as the transition program will be the rapid development of new energy vehicles also need steel pipe, even pure electric vehicles still need steel pipe, seamless steel tubes for electric cars damping. Some car manufacturers to develop the steel frame of a utility model electric four-wheel car, the car's frame chassis, subframe, double stringer, the front bracket and rear bracket fixed by steel pipe connected to form a whole . Many domestic steel pipe manufacturers to develop electric cars damping steel pipe, electric cars, cold rolled steel, this electric car with a high mechanical performance requirements of the cold-rolled steel pipe, so the chemical composition of the raw materials higher, extending the performance requirements. At present, the damping steel pipes of electric vehicles and electric vehicles are mainly concentrated in the range of small-diameter cold-rolled steel pipe specifications.
"Energy-saving and new energy vehicle development plan (2012 to 2020)", 2015, pure electric vehicles and plug-in hybrid vehicles and strive to reach 500,000 cumulative production and sales; 2020, pure electric vehicles and plug -in hybrid car production capacity of 2 million, the cumulative production and sales of over 5 million. With the implementation of energy-saving and new energy vehicle development plan (2012 to 2020), steel demand in the automobile industry will be further released. At the same time, the automotive industry has put forward higher requirements for the quality and performance of the steel pipe.
Imported automobile parts, about 2/3 of the automotive steel pipe is a high-precision welded steel pipes, high precision welded cold drawn (or cold-rolled) steel pipe.
Development of such steel pipe lagging, still rely on imports to make up for. Less of welded steel pipe steels, less applicable specifications, welded steel pipe deburring process instability, automotive steel pipe development generally cold-drawn, cold-rolled seamless steel pipe instead of a high-precision welded steel pipe. Welded steel pipe in order to save energy, to reduce the weight of the vehicle, the car should be high strength, high toughness direction of our car with a welded steel pipe to meet or exceed the world's advanced level.
The implementation of energy-saving and new energy automotive industry development plan (2012 to 2020) ", will lead to the rapid development of China's auto industry, the localization precision steel tubes for the automotive market opportunity, coupled with new models emerging automotive energy-saving, environmental protection requirements continue to increase, the car can be predicted with huge steel pipe market. Recently, the Shanghai steel industry, "second five" development plan "issued explicitly required for the development of new energy vehicles steel as the steel industry during the" 12th Five-Year development priorities. The Ministry of Planning during the "12th Five-Year" period, automobile production capacity from 23 million to 31 million by 2015. According to the data of steel for automobile manufacturing experience, estimated that a passenger car average about 1 ton of steel, commercial vehicles of steel in accordance with the heavy, medium, light, and the order of micro amount of steel were nine tons, 4 tons, 1.5 tons and 0.8 tons, which gifted special steel accounted for 30%. This shows that the future of steel pipe in the automotive industry come in handy, automotive steel market outlook optimistic.
