China FAMOUS Steel Engineering Company Company News

In the second half of the year, domestic steel production continued to grow at a high level, resulting in a sustained low volatility in the steel market. The off-season effect was obvious. In some areas, steel companies actively limited production and maintained a stable steel market. First, crude steel production is still at a relatively high level. From January to July, China's crude steel and steel output were 473 million tons, 577 million tons, and 698 million tons, respectively, up 6.7%, 9.0%, and 11.2% year-on-year. The growth rate slowed down compared with the first half of the year. In July, the output of pig iron, crude steel and steel in China was 68.31 million tons, 85.22 million tons and 100.58 million tons respectively, up by 0.6%, 5.0% and 9.6% respectively. The average daily output of crude steel and steel in China was 2.749 million tons. 3.414 million tons, down 5.8% and 4.4% respectively, but still at a relatively high level. Second, steel inventories continued to grow. Affected by factors such as the season and the decline in demand, steel inventories continued to grow. According to the statistics of China Iron and Steel Association, the total inventory in July was 12.71 million tons, an increase of 520,000 tons, an increase of 4.3%; an increase of 3.24 million tons compared with the same period of last year, an increase of 36.9%. Third, the steel market price is lower. Since mid-July, the prices of major steel products have continued to decline. In the first ten days of August, the prices of rebar and wire rods decreased significantly. The prices were 3,883 yuan/ton and 4,093 yuan/ton, respectively, down 126.9 yuan/ton and 99.7 yuan/ton respectively from the end of July, with a decrease of 3.2% and 2.4 respectively. %. Fourth, the price of iron ore has dropped significantly. At the end of July, the China Iron Ore Price Index (CIOPI) was 419.5 points, up 21.2 points month on month, an increase of 5.3%. In August, iron ore prices gradually slowed down after falling sharply. On August 22, the CIOPI index was 314.5 points, a decrease of 105.0 points (25.0%) from the end of July; the price of imported iron ore was US$83.92/ton, down 27.4% from the end of July. Fifth, some regional steel companies actively cut production. Recently, many enterprises in Shandong, Shanxi, Sichuan, Shaanxi, Gansu, Xinjiang and other places have reduced the supply of crude steel, limited production and efficiency, and digested the existing high-priced stocks by taking measures such as taking the initiative to stop production and maintenance. Jointly maintain stable market prices and effectively prevent market risks.

As a green construction method promoted and promoted by the country, prefabricated buildings are gradually becoming the mainstream trend in the future development of the construction sector. In the wave of Datong City actively participating in the energy revolution, vigorously promoting the use of prefabricated buildings is also a powerful practice for Datong to promote energy conservation and emission reduction and promote green development. Compared with cast-in-place monolithic buildings, the prefabricated building has a short construction period, is limited by climatic conditions, saves materials and energy, and produces less construction waste, so it is more environmentally friendly. In addition, in the design process, the precision building components ensure the building has good seismic performance and anti-corrosion performance, and has the advantages of avoiding repeated decoration, long life and maintenance-free. It is of great significance to vigorously develop prefabricated buildings to save resources and energy, reduce construction pollution, improve labor productivity and quality and safety, promote transformation and upgrading of the construction industry, and promote the development of new industries. To this end, Datong City has thoroughly implemented the national and provincial policy requirements for vigorously developing prefabricated buildings, further increased support, strengthened research and development of key technologies, and continued to promote the healthy development of fabricated buildings. Located in the “Green Capital” Datong New Energy Industrial City, the assembled green building integration industrial base has a total investment of about 2 billion yuan. It is led by green energy-saving assembly buildings and integrates R&D, design, demonstration, production, sales and logistics. At present, the steel tube bundle processing project, heavy steel structure project, PC project, solar power project, etc. have been settled. It is planned that the company will basically enter the production and start production by 2020, and the basic development of the park will be completed. The Zhengfang Limin (Tianzhen) Construction Industrialization Industrial Park project started construction last year, with a total planned land area of ​​1,500 mu, with a total investment of about 1 billion yuan. It is planned to be constructed in three phases. After the completion of the operation, it will realize a total output value of 12 billion yuan to solve the employment. More than 10,000 people have become the production base of prefabricated components for prefabricated buildings with the most complete varieties and the largest production capacity in North China.

The structure made mainly of steel is one of the main types of building structures. The steel is characterized by high strength, light weight and high rigidity, so it is especially suitable for building large-span and ultra-high and super-heavy buildings. The material is homogeneous and isotropic, and it is an ideal elastomer, which is in line with general engineering. Basic assumptions of mechanics; good plasticity and toughness, large deformation, good dynamic load; high degree of industrialization, high degree of mechanization; professional processing, high efficiency, good airtightness Therefore, it can be used to build gas tanks, oil tanks and transformers. The disadvantage is poor fire resistance and corrosion resistance. Mainly used for heavy-duty workshop load-bearing skeleton, power plant structure, shell and shell structure, towering TV tower and mast structure, bridge and hangar and other large-span structures, high-rise and super high-rise buildings. In the future, steel structures should be studied for high-strength steels, which greatly increase the strength of the yield point. In addition, new types of steels, such as H-beams (also known as wide-flange steels) and T-shaped steels and profiled steel plates, are required to accommodate large-span structures. And the need for super high-rise buildings.

The Nanjing Yangtze River Bridge is China's first double-layered public-rail dual-purpose bridge designed and built entirely of domestically produced materials. It breaks the assertion that foreign experts can't build bridges on the Nanjing River! The first generation of bridge builders in New China has created a milestone in China's self-reliance to build large bridges over the past eight years. On September 30, 1968, the Nanjing Yangtze River Bridge Railway Bridge was opened to traffic. On December 29 of the same year, the highway bridge was opened to traffic. Starting from the independent design and construction of the Nanjing Yangtze River Bridge, new bridge construction in China has made continuous breakthroughs. In the 21st century, the construction of high-speed railway bridges and cross-sea long bridges has entered a period of great development. In 2011, the Beijing-Shanghai high-speed rail Nanjing Dashengguan Yangtze River Bridge was opened to traffic. It is the world's first six-lane high-speed long-span railway bridge, marking China's bridge construction technology among the world's leading. In 2018, the world's longest sea-crossing bridge, the Hong Kong-Zhuhai-Macao Bridge, was completed and opened to traffic. This super-engineering in the ocean has set a number of worlds and has become a new benchmark for bridge construction in the world. According to statistics, since the 18th National Congress, more than half of the world's long-span bridges have appeared in China. More than half of the world's top 10 cross-sea long bridges, cable-stayed bridges, suspension bridges and arch bridges are built in China. At present, we also have a large number of world-class bridges such as the Pingtan Strait Gongtie Bridge, the Hutong Yangtze River Bridge, and the Wufengshan Yangtze River Bridge. The world's bridges such as “the longest, the biggest, the fastest...” will continue to be recorded. It was refreshed by China.

On July 29th, the 10th executive director (expansion) meeting of the 5th China Iron and Steel Industry Association and the model commendation meeting were held in Beijing. The theme of the conference was “actively consolidating the results of supply-side structural reforms and striving to promote the sustainable and healthy development of the steel industry”. More than 300 representatives (directors) and commended personnel from relevant government departments, research institutes, universities and steel companies attended the meeting.

Building a 1000-square-meter building in five days can save 35% of labor and improve work efficiency by 58%... Shanghai builders have "played new heights" in prefabricated buildings. The newly developed "Super High-performance Assembly Structure New System" (PCUS) has been successfully applied to the Shanghai Bailonggang Wastewater Treatment Plant Reconstruction Project, which not only saves transportation costs, labor costs for grouting sleeve materials, but also improves housing strength and quality. Even if it is overloaded with 200 tons of sand, it is as stable as Mount Tai. The current fashionable assembly building is like a building block. According to architectural experts, if traced back to the source, the prefabricated building can be traced back thousands of years: from the stone building to the wooden structure, the prototype of the prefabricated assembly is hidden. Therefore, “assembly” is the accumulation of human construction technology for many years. Only with the emergence of cement-based epoch-making materials and construction technology innovations derived from cement, on-site pouring has become the mainstream of modern architecture. It is the ultimate dream of the construction industry to make the house fast and good. The prefabricated building has successfully interpreted the “saving house” – building provinces, labor provinces and maintenance provinces. This has become the consensus of the whole society and has risen to the national strategy. The promotion of Shanghai has been continuously strengthened. The "13th Five-Year Plan for Housing Development in Shanghai" shows that Shanghai will change the housing construction model and comprehensively improve the level of housing green environmental protection and energy conservation. One of the ways to achieve this is to form a relatively complete technical standard system for fabricated residential buildings. By 2020, Shanghai's new residential buildings that meet the prefabricated construction conditions must adopt prefabricated technology to make the prefabrication rate of prefabricated residential buildings reach 40% or more, or the monomer assembly rate can reach more than 60%. Behind the word "province" of the prefabricated building, there are countless technicians' pains. Ma Yueqiang, deputy chief engineer of Shanghai Jiangong Second Construction Group, said that although the prefabricated building is like building blocks, it is not easy to operate. The key to ensuring safety is the effective connection between prefabricated components. The problem is that the existing connection structure is relatively complicated, and the sleeve grouting management is difficult... These difficulties restrict the development of the fabricated structure to some extent. To this end, in the field of prefabricated buildings, new technological breakthroughs are bound to come. Modern craftsmen work together to make the component nodes efficient and safe. Shanghai Jiangong Second Construction Group and Shanghai University of Technology, etc., carried out cooperation in production, education and research, focusing on the connection of new prefabricated component nodes, and using a kind of “super high performance concrete” as post-casting material to study the PCUS system. This kind of "ultra-high performance concrete" is called UHPC, which has filled the gap in China's high-strength steel connection technology. It is ideal for using it as a binder. The operation process is also relatively simple - first put the prefabricated beam and column together. Then pour it at the joint to complete the construction quickly. It is estimated that this new system can save 39% of the cost.
