Steel steel market needs to develop a great variety
2013-08-12 Reads : 44
"Beautiful China" calls for green building. Steel structures in harmony with nature as a cycle of low-carbon green building, along with China's accelerated pace of urbanization, is rapidly rising, causing the steel industry's concern and attention. Development of new varieties of steel products to meet market demand for steel structure steel, iron and steel enterprises do not say long way to go. A Steel Works Co., Ltd., general manager said that in carbon emissions, the traditional architecture of carbon emissions accounted for almost 50%, the proportion is far higher than the transportation and industrial sectors. For fog and haze early this year, most people's first reaction is to motor vehicle exhaust emissions actions, in fact, the real culprit is traditional building materials such as cement. China is a super cement producing country, in the "making the city" campaign in the amount of per capita has more than one ton of cement per one square meter house built on 0.8 tons of carbon emissions. In Europe, Australia and Japan, the local construction industry is very concerned about carbon constraints and the recycling economy. There, as a prefabricated steel structure house in harmony with nature's green recycling low-carbon buildings, has been developed to a very sound stage, accounting for 40% of all residential buildings above. It can maximize the conservation of resources, protection of the environment, reduce pollution, provide people with healthy, suitable and efficient use of space. Modern building industry at an international exposition, the State Department of Housing and official pointed out that the steel can be recycled, while the concrete is unidirectional, limestone becomes concrete, limestone can no longer be turned into a. Industrialization of residential production if spread in China, construction waste will be reduced by approximately 83%, a decrease of approximately 60% material loss, increased 60 percent recyclable materials, building energy saving up to 50%. People were born house, house due to the excellent material to steel and concrete (concrete) will be the trend. At present, the domestic residential construction in the highest standard is "four one green", namely: energy, land, water, materials and environmental protection. Internationally, in the development of green building has a wide spread of the "three R principles", namely: reduce (reduction), reuse (reuse) and recycle (recycling). These should become China abide by the tenets of the development of the housing industry. It should be noted that in recent years, as a new recycling building industry system ---- Steel Green industrialized building system in our country is rapidly formed steel for the steel to create a huge market. Meanwhile, the steel structure steel propose new and higher requirements. Currently there is less variety of steel structure steel, poor quality issues must be changed. Today, China's construction steel industry has formed a huge industry, only the main steel structure manufacturing output to more than 60 billion yuan, has been formed to steel production, steel structure design, component processing and production, installation, and associated components industry An industrial chain. Construction steel industry, but also led to the development of related industries, also stimulating demand for steel structure steel. Large areas of steel, especially steel green building system, it will break the real estate, construction, machinery and equipment manufacturing, green building, new building materials, disaster prevention and mitigation, kitchen appliances boundaries between decoration and other industries, set to become a new The recycling of industrialized building industry system; also be real estate capital flowed back into the real economy in modern manufacturing to achieve economic transformation and upgrading. In the long run, it is a national strategic resource reserves of emerging industries, can be hidden steel in construction, possession of wealth among the people, for the benefit of future generations. Thus all these years, China's steel buildings and residential development is continuing, according to preliminary statistics, Beijing, Tianjin, Shanghai, Zhejiang, Hubei, Inner Mongolia and other provinces and cities have been developed or built steel housing more than 10 million square meters, the Beijing Olympic Games. " Bird's Nest "," Water Cube ", CCTV new building, the Shanghai World Centre, a large number of the world's advanced level of steel construction, and has become the main structure with steel for the construction of a model of engineering applications. Thus, for steel manufacturing large quantities of steel, high quality, variety, there are ordinary steel, has excellent steel, with steel. Which accounts for a large proportion of excellent steel, especially high strength low alloy steel, weathering steel, refractory steel, ultra-high-strength bolts, high performance pre-painted steel, high alloy plate, etc., the demand is also increasing. Recently, East Tower, a notice Guodian Taizhou Power Plant Phase II 2 × 1000MW ultra-supercritical coal-fired units double reheat projects, companies with Guodian Taizhou Power Generation Co., Ltd. signed steel procurement contract, the contract price of 79.5 million yuan. The company's main steel structure and tower products, including steel products are mainly used in thermal power plants and nuclear power plants, this contract is the company following the Guodian Taizhou Power Company Limited a 2 × 1000MW project main steel plant project in Taizhou again power generation companies. May 26 this year, with the first section of precision steel columns in place, Zijin Plaza Xiamen Airlines B tower steel structure project officially entered the construction phase. AVIC Zijin Plaza points A, B two building height reached 194.3 meters of high-rise buildings, are used in the steel concrete steel frame - core tube structure system. Where B is the hotel tower roof truss design corridor between steel structure, the maximum welding thickness of 40 mm and weighing over 100 tons. Otherwise a building height of 79.60 m five-star hotels, a large concentration of commercial and matching skirt and other buildings with a total gross floor area of ??325,941.06 square meters, with a total of about 15,000 tons of steel. China's steel out of the country, to develop the international market. Such as the manufacture of steel Baosteel large buildings will debut in Chile, support and commitment to build power facilities of the task. This is after Brazil, Baosteel steel into the South American market has gained an overseas orders. In recent years, Chile is one of the world's economic hotspots. Baosteel Steel Structure Engineering Division to purchase 4,000 tons of steel structure is a Chilean electricity supplier, is headquartered in San Diego, is primarily responsible to the nearby state and private copper to provide electricity. Baosteel steel structure provided will be used for the electricity supplier cooperation with Mitsubishi Heavy Industries, the new power plant unit project facilities. The new power plant project by Mitsubishi Heavy Industries, the total package. It is understood that the project needed to order 4000 tons of steel structure, will be fully completed during the year of delivery. Recently, the domestic steel production line newly increased. Recently, the annual output of 20,000 tons of steel and 1,000,000 m2 color plate production line settled in g East, which is the county's second year, the successful signing key projects. The total investment is 120 million yuan, the construction of light steel production line 1, heavy steel production line 2, new building materials (color plate) production line 4, an annual output of 20,000 tons of steel and one million square meters color plates, will be held in early May construction, commissioning in late October. After the project, the annual output value of 260 million yuan, sales income of 120 million yuan, profits and taxes 18 million yuan, while the demand for steel will drive steel. Indeed, the rapid development of China's steel industry, steel steel consumption is increasing, also accelerated the production of steel and steel research and development, compared with developed countries, but there is still not a small gap, one of which includes a high performance steels strength steel, high seismic performance of steel, high performance steel and welding thick plate and thin materials such as steel production there less, and poor quality. Insiders pointed out that construction steel has a "lightweight, high strength, good plasticity" advantage and "light, faster, better, cheaper" feature, in addition to having a lightweight, high strength, excellent material properties, fabrication and installation of high degree of industrialization, should Removal and good durability and other advantages, it also has help save resources, reduce carbon emissions, can be recycled, the effective realization of "four an environmentally friendly" green claim superiority. Therefore, the steel used in the steel also require light weight, high strength, corrosion resistance, and now some of the steel works "stupid, heavy, big", highlighting the flaws steel steel. Such as the use of high-strength low-alloy structural steel replacement carbon steel (Q235) can save 15% -20% of steel and reduce the weight of the structure. High-strength low-alloy structural steel should be used for large structures, heavy structure, large span structures, high-rise buildings, bridge engineering, withstand dynamic loads combined impact load structure, reduce the weight of the structure, save a lot of steel. At present, the amount is not large steel structure steel, which is China's penetration is not high steel construction has a direct relationship. In the United States, Japan, these steel buildings in countries with high penetration, steel steel steel production capacity has reached 30%, while China's steel industry, steel consumption is less than 10% of steel production. Cause such a big difference for many reasons, one of which is "still in the habit of China's iron and steel enterprises and other users find the door, rather than take the initiative to actively promote the development and performance of steel products." Some steel industry experts think so. Some steel manufacturing sector operators also believe that part of the iron and steel enterprises steel manufacturing industry's attention is not high, and some are reluctant to undertake hundreds of tons of steel, thousands of tons of small batch orders, coupled with some high performance steels, including high-strength steel, high seismic performance of steel, high welding performance steels, as well as extra-thick steel plates and thin materials such as steel production there less, and poor quality, so they needed source of almost all steel products on imports. Thus forming a very strange phenomenon: the one hand, China's steel industry serious excess capacity, a large number of steel mills in the warehouse backlog in unsold, steel profits shrunk dramatically and even face a loss; On the other hand, a group of Steel companies took orders but can not find the user manufacturers, the required steel steel needs to rely heavily on imports. China's steel industry is facing new challenges, mainly in the first compared with developed countries, there is a gap, the gap is mainly reflected in the small proportion of construction steel, steel structure housing a small proportion. The second is from the scientific and technological innovation, the major challenge is the new materials, new technologies, new processes, new equipment can not meet the demand for steel housing industry. Three standard specification is complete and perfect from the challenges, the lack of steel housing, metal walls, roof, new energy-saving materials such as water paints and other standards, technical norms. Especially the deepening steel design standards for the industry standard no. At present, China's national standards for steel 8, industry standard 25, there are 10 local standards, steel, steel products and materials Standard 46, the standard five fasteners, welding material standard 11, the design standard drawings Set incomplete 22. Four from industrial development policy challenge now is not yet worked out an effective policy of advancing steel housing. However, as China's "new four modernizations" The implementation of China's steel industry usher in a new development opportunities and broad prospects. Premier Li Keqiang made an inspection tour to go new industrialization with Chinese characteristics, information technology, urbanization, agricultural modernization path. In the "new four modernizations" goals, adhere to green development, low-carbon development cycle of development will become the basic concept of sustainable development has become a new economic transition period, we set goals and important basis for policy. January 1, 2013, the State Council to Guo Ban Fa [2013] No.1 forwarded National Development and Reform Commission, the Ministry of Housing and Urban Construction, the "Green Building Action Plan" clearly states: Promotion suitable for industrial production of prefabricated concrete, steel and other building system, improve the level of industrialization of construction technology integration. Recently, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, "Twelve Five" during the New Green Building 1 billion square meters. To the end of 2015, 20% of urban new buildings meet green building standards. Among them, the steel construction is becoming one of the development of green buildings. Ministry of Housing and Urban-Rural Development "construction" Twelfth Five-Year "development plan" requirement, "Twelve Five" during the construction process of building products to increase the value of the unit energy consumption decreased by 10%, C60 concrete amount reaches more than 10% of the total volume, HRB400 rebar consumption reached a total amount of more than 45% increase in the proportion of steel works. In this regard, some analysts expect to "Twelve Five" period, China's steel production will reach 50 million to 65 million tons, the industry outlook. According to this goal, steel steel steel enterprises should further enhance the quality, increase product development and marketing applications, efforts to increase the structural steel and high-performance connections with a variety of materials, expanding thin-walled H-section steel production and other economic profiles ; complete series of structural steel products and applications scale; promotion weathering steel, refractory steel, color coated steel, etc. Application; develop ultra high strength bolts, high performance pre-painted steel, high alloy plate, etc. strive our steel basic steel used in construction to achieve localization. Iron and steel enterprises to remind the industry, as the country's growing importance of environmental protection, green, energy-efficient buildings will become the next focus of urban construction. In urbanization, driven by green steel building market size will be very large, on the one trillion yuan is expected to have a huge market is accelerating the formation. Iron and steel enterprises, changing concepts, enter the steel industry, after all, to achieve restructuring and development of a new road. Government and steel industry iron and steel enterprises should all be given more attention. Sources of resources Steel Window
