The 2014 Moscow International Motor Show was staged at the CROCUS International Exhibition Center from August 27th to September 7th.
Great Wall Motor Company's Haval H2, Haval H6, Haval H8, Haval H9, Coupe C and Haval Dakar Racing, Lifan Motors' new X50 SUV, Smily hatchback, Solano sedan and Changan Yidong, Zhishang XT, Rui Wei Many models of the CS35, CS75 and other Chinese car companies appeared on the stage and met with Russian audiences. .
What is interesting is that on the eve of the Moscow International Motor Show, the Great Wall and Lifan have also increased their investment in localized production in Russia.
According to the report of the Russian media, the father of China Great Wall Motor Co., Ltd. has officially opened a large factory in the Uzlovaya Industrial Park in Tula, Russia. This whole process of stamping, welding, painting and final assembly covers an area of ​​2.16 million square meters, with an investment of about 520 million US dollars (about 3.2 billion yuan). It is expected to be completed and put into production in 2017, by 2020. At that time, it will form an annual capacity of 150,000 "Haval" brand cars and create 2,500 jobs.
The relevant agreement of the project was signed by the Russian delegation in Shanghai on May 20, 2014. The Tula State Government of Russia will provide China Great Wall Motor Co., Ltd. with a 10-year series of local preferential policies, including zero property. Tax and only 15.5% profit tax. On this day, after Chinese President Xi Jinping and Russian President Vladimir Putin met, they also signed the "Joint Statement of the People's Republic of China and the Russian Federation on the New Stage of Comprehensive Strategic Cooperation Partnership." The two sides will improve the efficiency of cooperation in high-tech fields and continue. Efforts will be made to promote bilateral trade volume to reach 100 billion U.S. dollars by 2015 and 200 billion U.S. dollars by 2020, and implement a memorandum of cooperation on Sino-Russian intergovernmental economic modernization to ensure bilateral trade balance, optimize trade structure, and increase mutual investment.
According to reports, the Uzlovaya Industrial Park is only 40 kilometers away from the Russian state of Tula, and China Great Wall Motor Company is the first settler. Tula, Russia, is located in the middle of the Eastern European Plain and in the northern part of the Russian-Russian hills (with a height of 293 meters). It borders Lipetsk in the south and southeast, the flag state of Tula in the Russian Federation in the southwest, the border with Kaluga in the west and northwest, the Moscow region in the north and northeast, and the Ryazan region in the east. Adjacent. The state's capital, Tula, was the metallurgical manufacturing center of Russia at the time in the 19th century. It established the first samovar manufacturing plant in Russia, and its samovar was famous around the world. The Tula State Government has been actively attracting investment and dreams of building the region into a car manufacturing base for multinational automakers like Kaluga, Russia. However, before reaching an agreement with China Great Wall Motor, there has been no major automobile manufacturing for a long time. The project settled in the area. In 2011, it was only planned to use the original Kangbain factory in Tula to produce domestic “little bear†small displacement vehicles.
Russia’s Tula State Governor Vladimir Gruz Jeff actively promoted the Great Wall project in China. He said at the groundbreaking ceremony of the Great Wall Factory in China, “China’s Great Wall Motor Company’s annual car sales will exceed 900,000. In Tula The state, the company will bring the most modern production. It is not a screwdriver assembly, but a full-process car production, and will also start production of engines and transmissions." He believes that Chinese partners will produce high-quality vehicles that are competitively priced and meet the needs of Russian consumers. "We are not only known for producing weapons, gingerbread and tea, but also for automobile manufacturing in the future."
At the same time, the Russian government of Tula said it would purchase Great Wall Motors produced in Tula. Governor Vladimir Gruz Jeff is also willing to replace his car with the "Haval" car produced in Tula. The local government of Tula will make every effort to create an industrial park that will provide good conditions for automakers and other companies with high value-added, high wages and high productivity.
In addition to the annual production of 150,000 "Haval" cars in Tula, Great Wall Motor Russia's general agent Elito also assembled and produced the Great Wall H3 SUV and H5 SUV and Feng Jun pickup in the Lipetsk region of Russia. The production started in March with a maximum capacity of 150,000 vehicles/year and a total investment of 10 billion rubles (already invested 3 billion rubles). However, its agreement with Great Wall Motor will be valid until 2017.
There is no such thing. In Russia, there is another big car company from China, Lifan, which plans to invest 150 million US dollars in the Kaluga region of Russia. In the initial phase, it plans to produce tens of thousands of Lifan cars annually, and may gradually increase the annual production capacity to 100,000 units. Previously, the Devis assembly plant in Circassix, Russia, produced the Lifan Breez, Solano, Smily and X60 models.
According to data from the European Business Association Automobile Manufacturers Committee, in 2013 Lifan became the leader of Chinese brand cars in the Russian auto market, selling 27,467 vehicles (up 34% year-on-year), accounting for 1% of the market share; and Great Wall Motors The share in the Russian market accounted for 0.7%, and 19,900 units were sold in that year (up 39% year-on-year).
In July 2014, sales of Chinese brand cars in the Russian auto market reached 6,370 units, a decrease of 33.43% from the previous year's 9569 units, but an increase of 5.85% from the previous month's sales. The market share increased slightly from 3.02% in the previous month to 3.52%, but lower than 4.08% in the same period last year. Lifan continued to maintain its leading position among Chinese counterparts, selling 1816 vehicles, but a negative growth of 29% year-on-year and an increase of 99 vehicles. The Great Wall ranked third with 1,307 vehicles sold, a negative growth of 23% year-on-year and an increase of 112 vehicles. .
From January to July, the cumulative sales of Chinese brands in Russia reached 46,200 units, a decrease of 17% from the 55,800 units in the same period last year. The share of the Russian passenger car market also fell to 3.28% from 3.95% in the same period last year. Lifan surpassed Geely, Chery and Great Wall to rank first, with a total sales of 12011 vehicles, a negative growth of 15% year-on-year; while Great Wall Motor still ranked fourth, with a total of 9,403 vehicles sold, a negative growth of 22%.
Analysts believe that Chinese automakers have established their own factories in Russia, a new milestone. These large-scale investment projects are not aimed at the current market, but focus on the long-term. Although the performance of the Russian auto market has been frustrating in recent months, the outlook for the Russian auto market is still optimistic. The "sanctions" and "anti-sanctions" between Russia and Europe and the United States and the further development of a more intimate and comprehensive strategic partnership of cooperation have provided unprecedented opportunities for Chinese car companies.
However, experts also pointed out that Chinese automakers are planning more than 100,000 units of production capacity, equivalent to about 5% of the overall market share, which may exceed supply. In the foreseeable future, it may not be easy to achieve these ambitious ideas. In order to compete with mid- to high-end models produced by auto companies in Germany and Japan, and to compete with economic models produced by auto companies such as South Korea, France, Japan and Russia Volga, Chinese automakers need to invest more in technological innovation. . In the long run, the number of cars in Russia is far lower than that in Europe, and the automobile market will gradually pick up. If China's cars are of good quality and low prices, there will be greater market opportunities.
This standard replaces GB/T8162-2008 "structure with seamless steel tube". This standard is compared with GB/T8162-2008, the main change is as follows:
This standard is applicable to the general structure and mechanical structure of Seamless Steel Pipe, seamless Steel Pipe, fluid seamless steel pipe standard for the general seamless steel pipe. The main difference between it and the structure of seamless steel tube is the hydraulic test or the ultrasonic, eddy current and magnetic flux leakage testing. Therefore, it is not suitable to use fluid seamless steel pipe in the standard of pressure pipe. Seamless steel pipe for the outside diameter, wall thickness, thick walled seamless steel pipe is mainly used for mechanical processing, coal, hydraulic steel, and other purposes. Thick walled seamless steel pipe is divided into 10#, 20#, 35#, 16Mn, 45#, 12Cr1MoV, 27SiMn, 10CrMo910, 15CrMo, 35CrMo, etc.. The classification of thick walled seamless steel pipe hot rolled thick wall seamless steel pipe, cold rolled thick wall seamless steel pipe, seamless steel tube, cold drawn thick wall extrusion thick wall seamless steel tube, pipe jacking. Stainless steel seamless steel pipe structure (GB/T14975-1994) is widely used in chemical, petroleum, hot-rolled stainless steel made of textile, medical, food, machinery and other industrial anti-corrosion pipes and structural parts and parts of the (extrusion, expansion) and cold drawing (rolling) seamless steel tube.

Scope of use, including the general structure and mechanical structure, a large number of construction, machinery, transportation, aviation, oil and other industries of various structures.
Delamination defect
In view of the mechanism, it is generally believed that the non metallic inclusions in the tube will destroy the continuity and compactness of the 45# structure, and the serious inclusion of the 45# structure will produce delamination. The other one is that the hydrogen induced crack, because of hydrogen in steel aggregation caused by internal gas metal pressure is too high, the formation of white spots in the compact inner tube, the crack occurred in the rolling process, and ultimately the formation of lamination defect. In addition, the uneven deformation of the two roll cross piercing is produced by the stress exceeding the plastic strength.
In the case of strict smelting control, there are third kinds of cases, the control measures:
1, improve the plastic and toughness of 45# steel pipe
Improving the cleanliness of molten steel, reduce harmful inclusions in continuous casting billet; increase the proportion of equiaxed grains, reduce the central segregation and central porosity; the cooling system is reasonable, avoid the slab internal crack; on line slab or billet by slow cooling process, reduce internal stress, in which the microstructure and mechanical properties of pipe billet and finished 45# steel structure meet the technical standard requirements.
2, reasonable control of heating temperature
The best heating temperature was selected by the determination of the thermoplastic curve. Tube billet heating should also pay attention to enough holding time, in order to reduce the deformation resistance and improve the ductility of 45# steel pipe.
3, reduce the roll speed
The roller speed is the key parameter of the perforation process. The roller speed is changed from low to high, and there is a critical roll speed which begins to appear. When the roller rotating speed is low, the tube blank is easy to form a hole cavity. When the roller speed is higher, the tube blank and the 45# structure steel tube are easy to form the delamination defect. In order to eliminate the pipe blank and 45# structure, the roller speed should be reduced to the critical roll speed, which is lower than that of the layer.
Structure tube weight calculation formula: [(outside diameter - wall thickness) * wall thickness of]*0.02466=kg/ meters (weight per meter)
