In response to the construction of ecological civilization construction steel into strategic repositories

In response to the construction of ecological civilization construction steel into strategic repositories

Foshan Steel data show that in 2013 China's crude steel production was 779 million tons, accounting for 48.5 percent of global production, steel production quantities from single point of view, China's steel production in the world's steel output ranked first start of "throne" has is a veritable "steel big country."

However, if this use "Iron power" to describe the current situation of China's steel industry, but also premature. Because China lacks high-quality iron ore, itself dependent on foreign imports, which led to a lack of bargaining power of steel prices in the international iron ore market. For a long time, fluctuations in the market price of iron ore severe impact on China's steel enterprises production and business activities, together also restricted to China's macro-economic development strategy.

In response, industry experts believe that with the State Council's "green building action plan" to get around the concrete implementation, in order to build the steel structure represented by the implementation of green building intensified, bringing increased demand for construction steel, one can partially steel prices defuse chronic overcapacity, with the long-term point of view, but also for the national Steel strategic storage supply useful way.

Developed "hidden steel in the construction of" strategic material storage should not be overlooked

As a necessity of industrial production, the steel capital of the country is crucial. Japan, the United States and other developed countries, the strategic importance of the steel capital of storage never slack off.

Japan, for example, in the construction of roads, workers will first lay a thick layer of high-quality steel in the roadbed, and perfusion asphalt pavement. This not only greatly enhance the durability and safety of the road, also regarded as a useful way of steel storage capital, many highway construction, that this is a large steel warehouse. In case of emergency, buried beneath the road surface plates can be directly used for engineering repair, earthquake construction, and even military production.

In addition to steel storage by road, in many developed countries, "hidden steel in the construction of" strategic storage has long been popular consciousness. Data show that, at present in the UK, 95% of construction steel construction steel get a useful recovery, in which 10% can be reused later by a simple process, while 85% is recycled through such means as recycling again.

Now, with China's new urbanization continues in full swing in advance, shelter needs of the urban population will continue to usher in a new rigid growth point, this is a good opportunity for development. In this regard, the Chinese steel industry first person, the first domestic steel structure of listed companies at the helm, Hsiao Zhejiang Hangzhou Steel Co., Ltd., a single silver wood believes green building construction field as a representative of steel shelter the most energy saving, with many of the characteristics fit the strategy of sustainable development: build fast, easy removal, green and high recovery rate.

In addition, because the seismic safety of steel construction, corrosion simply through regular maintenance, the construction of life can reach more than 80 years, therefore, the savings from the future development of the national strategy point of view, the "hidden steel in construction," we should be good way.

Steel construction act as "strategic repository" hidden steel in China for the benefit of generations

Comparison of the developed countries, China in the re-utilization of existing scrap recycling, technology is relatively backward, and then recycled scrap rate of less than 50%. Now, with rising crude steel production capacity, the total amount of scrap steel are rising, a lot of scrap iron and steel can not be handled properly, unhealthy production structure caused serious waste of social capital.

Vice President Hangxiao Sui believes that steel construction has a long life cycle of construction, steel recoveries up to 90% advantage, once able to build many, steel construction has the potential to become "steel storage warehouse" in.

Together, if able to steel construction and urbanization of China, as well as the protection of home combined with the implementation of many steel construction, which will become a huge repository of high-quality steel strategy.

In this regard, Chen Rui suggested that it should take advantage of China's current foreign exchange reserves adequate, continuous appreciation of the yuan favorable environment, a lot of buying high-quality iron ore, put it into a modern industrial smelting blood - high-quality steel, large-scale application in order steel construction for the construction of the new representative of the green, to enhance the utilization of scrap steel recycling, play steel construction of the "life cycle" of the advantages of a strategic approach will be critical to achieve the transformation and upgrading of the steel industry, and "possession of steel in construction, wealth with the people, "the strategy of win-win development.

Help develop national strategies for Capital Steel shelter storage

In recent years, Chinese steel construction industry has developed rapidly, especially with the accelerated urbanization and inspire a new round of home rigid demand for steel shelter implementation provides a solid foundation. Chinese construction steel construction Metal Structure Association branch president of the party defending the show:. "From the future development trend, steel is the main residence of the steel industry's future growth."

Home construction steel have industrialization, industrialization, standardization and other characteristics, is more conducive to the realization "hidden steel in the construction of" only in the construction of new urbanization vigorously steel shelter, shelter ahead steel industry, the completion of the base accumulation, talent successfully build "Steel warehouse."

As industrial steel shelter promoters and leaders in the field of exploration Hangxiao steel shelter, has been based on technology research and development, at the forefront of the industry. It is understood that Hangxiao steel beam has been successfully applied for shelter system patent portfolio structure. Sui briefed reporters on the system is applied to the residence Hangxiao previous century hometown Wuhan Steel Community, as well as the basis of the nation's largest home technology systems Baotou Steel square County community of big capital, carried out innovation and improvement.

On the one hand, the system will significantly reduce the cost of steel shelter, so that the concrete shelter with flat or even lower than the cost of concrete, steel shelter makes large-scale applications become possible; on the other hand, the use of its core technology "steel beam" of residence in enhancing the safety factor of steel together, useful to expand the area of residence within the habitable for tenants to bring a more humane living experience, the market prospect is broad.

In this regard, the chairman Hangxiao single silver wood believes that with different concrete shelter, steel homes are built "full life cycle". In the course of life, from construction to steel construction demolition, from demolition to recycling, from recycling to reprocessing, from reprocessing to be built entirely of steel to achieve a low-loss recycling.

Therefore, once the large-scale application of steel shelter, which is a veritable "Steel warehouse", which store the steel capital of the completion strategy, to achieve green, low-carbon sustainable development, have a milestone.

However, we should see that Chinese steel construction started late. "Steel and the United States, Japan and other developed countries is generally higher than 50% share of the construction compared to the construction of China's share of all steel construction with less than 10%, steel accounts for 10 percent of foreign construction steel production - 30%, with an annual output of 700 million tons of steel accounted for China, 10% that is 70 million tons. However, China is now the construction of an annual steel consumption was less than 3,000 tons. such a scale can not meet the total demand of strategic storage "Hangxiao single silver wood chairman told reporters show that if we want to achieve developed country" hidden steel in the construction of "level, Chinese steel construction industry is a" road is long Come. "

So, with the further deepening the country's economic reform and industrial optimization, and upstream and downstream steel enterprises steel enterprises to establish closer cooperation to enhance the utilization of iron ore, steel, and steel scrap recycling levels, and steel construction business together, let the real talent "Steel construction of a national repository steel housing strategy" to achieve the goal of wealth with the people.
