"the promotion and application of high-strength steel bars involves different industries, different subjects and multiple links, which requires overall consideration and coordination. Five issues such as the contradiction between supply and demand in the promotion and application of high-strength steel bars, market mechanism and government guidance, overall and local interests, technological progressiveness and economic applicability, national promotion and key demonstration should be properly handled." On April 12, at the "National Work Conference on promoting the application of high-strength steel bars" organized by the Ministry of housing and urban rural development and the Ministry of industry and information technology, Deputy Minister of housing and urban rural development chendavide said

the meeting is mainly to mobilize, deploy, promote and apply high-strength reinforcement. David Chen said that the promotion and application of high-strength steel bars is a breakthrough in the transformation and upgrading of the iron and steel industry and an effective way to promote the technological progress of the construction industry. By using high-strength steel bars in construction projects, the amount of steel bars can be reduced, and the energy and resource consumption and pollutant emissions of steel production can be reduced accordingly. At the same time, the pressure of iron ore import, coal demand and power supply will be relieved

Chen Yanhai, director of the raw materials department of the Ministry of industry and information technology, said that the iron and steel industry should focus on the upgrading of iron and steel materials, focusing on strengthening enterprise technological innovation, establishing upstream and downstream cooperation mechanisms, improving the standards of iron and steel materials, and eliminating backward equipment and products

upgrading is imminent

Chen Yanhai said that the steel industry is the basic industry of the national economy. Steel materials are mainly used in construction, machinery, automobiles, ships, household appliances, petroleum, railways, transportation, electric power and other fields. During the 12th Five Year Plan period, China's major industrial industries will be in a critical period of transformation from large to strong. The upgrading of major industrial products is inseparable from high-performance steel materials. Steel for construction accounts for about 50% of steel consumption, steel components account for 70% of the weight of vehicles such as automobiles, and steel materials account for 90% of energy production equipment. Therefore, industrial transformation and upgrading also depend on the upgrading of steel materials to a certain extent

in 2011, China's crude steel output reached 683 million tons, accounting for 46% of the global output. China consumes nearly half of the world's steel materials, but the total economic output created accounts for only 9.5% of the world. In the current situation of huge production capacity, prominent excess contradictions, increasingly fierce homogenization competition and sluggish downstream demand, the iron and steel industry must abandon the old way of focusing on scale, light quality and low-cost expansion, vigorously promote the upgrading of iron and steel materials, and accelerate the transformation of development mode to intensive connotation, quality and efficiency

the production and operation situation is grim

Chen Yanhai said that the iron and steel industry is in the middle of the industrial chain. The upstream is squeezed by the sharp rise in coal, electricity, logistics, ore and other prices and the rise in labor costs, while the downstream is affected by the weakening demand growth of major steel industries such as construction, automobile, shipbuilding, machinery, household appliances and so on. Since the second half of 2011, the profitability of the whole industry has been at a low level for more than a decade

according to statistics, from January to February this year, the cumulative sales profit margin of key large and medium-sized iron and steel enterprises was -0.51%. Among the 29 steel production enterprises with more than 5 million tons, 13 enterprises lost money, with a loss of 44.8%. The cumulative loss was 2.6 billion yuan, and the production and operation situation was very serious. In this environment, steel enterprises must take the transformation from producers to service providers as the starting point, and take independent innovation and technological transformation as the support, comprehensively promote the improvement of steel varieties and quality, improve the quality and grade of large-scale steel products, and accelerate the transformation and upgrading of the steel industry

in the construction field, if the nearly 100million tons of 335 MPa ordinary steel bars currently used are replaced by 400 MPa high-strength steel bars, the consumption of steel materials can be reduced by about 10million tons per year, and the consumption of iron ore and carbon dioxide emissions can be reduced by about 16million tons and 20million tons respectively. In the field of transportation, if the third generation automotive steel with high strength, high plasticity and high toughness is used, it can not only improve the safety of vehicles, but also reduce automotive steel by more than 10%. Using ship plates with a yield strength of more than 590 MPA can reduce marine steel by more than 18%. Promoting the upgrading of steel materials can not only reduce the consumption of steel materials, but also improve the payload of vehicles. In the field of household appliances, a large number of wide, high-strength, thin gauge steel plates can not only improve the production efficiency of household appliances, reduce the weight of household appliances, but also help to reduce the use of steel materials. To this end, Chen Yanhai stressed that during the "12th Five Year Plan" period, the iron and steel industry should focus on key steel industries, establish upstream and downstream high-performance steel production and application cooperation mechanisms one by one, and improve the application demonstration platform. By revising and improving the product standards of steel materials and the specifications for steel use in downstream industries, and promoting the reduction of steel use, it is estimated that the whole society can reduce the consumption of steel materials by more than 30million tons during the 12th Five Year Plan period, which will greatly promote the energy conservation and emission reduction of the whole society and meet the needs of the transformation and upgrading of downstream industries. At the same time, it can also significantly alleviate the pressure of China's high external dependence on iron ore

strengthen enterprise technological innovation

Chen Yanhai said that strengthening technological innovation is the key link of industrial transformation and upgrading. Iron and steel enterprises should establish a complete technological innovation system and form an innovation mechanism of "production learning research application" guided by the government, with the participation of enterprise subjects, universities and research institutions, and guided by the needs of downstream industries. Iron and steel enterprises with more than 1million tons should establish enterprise technology centers, increase R & D investment, and strive to increase the proportion of R & D investment in main business income to more than 1.5% by 2015, and key backbone enterprises to more than 3%. Focusing on industrial transformation and upgrading and the needs of strategic emerging industries, we should focus on developing the production technology and product application technology of steel materials such as high-strength construction steel, high-performance automotive steel, marine steel, engineering machinery steel, electric power steel, and provide users with application solutions of high-performance steel materials

establish upstream and downstream cooperation mechanism

Chen Yanhai said that the establishment of cooperation mechanism between the steel industry and downstream industries is the focus of promoting the upgrading of steel materials. The iron and steel industry should establish a cooperation mechanism for the production and application of high-performance steel with the downstream steel industry. Promote downstream enterprises to establish a demonstration platform for the application of high-performance steel materials with steel enterprises and end users, coordinate innovation, accelerate the upgrading of large-scale and wide-ranging steel products, promote the industrialization of key steel varieties, and promote the sustainable and healthy development of the steel industry and downstream steel industry

Chen Yanhai pointed out that during the "12th Five Year Plan" period, we will focus on establishing upstream and downstream cooperation platforms with construction, machinery, automobile, shipbuilding, household appliances and other industries to improve the overall technological progress of the industrial chain and improve the core competitiveness. The construction industry will focus on promoting high-strength steel bars of 400 MPa and above; The machinery industry focuses on promoting high-performance bearing steel, gear steel, spring steel, etc; The automobile industry will focus on promoting high-strength automobile plates and establishing a new generation of automobile steel system; The shipbuilding industry focuses on the research and development and promotion of high-strength wide and thick plates and corrosion-resistant ship plates; The household appliance industry focuses on promoting high-strength and high surface quality steel

improve steel material standards

Chen Yanhai said that advanced and applicable standards are the embodiment of industrial competitiveness, and standard upgrading has become a new driving force leading industrial upgrading. The iron and steel industry should work with the downstream steel industry to strengthen the application of comprehensive standardization in industry and improve the level of iron and steel material standards and downstream steel specifications. According to the development and application of iron and steel materials, the standards for iron and steel materials with a large amount and a wide range of construction steel, railway steel, mechanical equipment steel and so on should be revised in time. Strengthen the research on the demand of strategic emerging industries for high-performance steel materials, and formulate relevant product standards in a timely manner

strengthen the connection with downstream steel specifications to meet the needs of downstream industry transformation and upgrading. At present, it is necessary to speed up the revision of steel standards for reinforced concrete and the upgrading of some special steel products to meet the development of construction industry and equipment manufacturing industry. At the same time, we should strengthen the product certification of high-performance steel materials according to the standards, guide the downstream industry to use them correctly, and prevent confusion in the application process. In particular, high-strength steel bars are produced by microalloying process, fine grain process and waste heat treatment process. We should carry out the certification of high-strength reinforcement as soon as possible
