Carry on the past and open the future. The past 2018 was the best year for my country's iron and steel industry in the past 10 years, and the quality and efficiency of the industry's operations have steadily improved. The year we are ushering in 2019 marks the 70th anniversary of the founding of New China. It is also a crucial year for my country to deepen supply-side structural reforms, accelerate the construction of a manufacturing power, and promote high-quality development. As one of the important industries supporting the country's high-quality development, the iron and steel industry must also deepen supply-side structural reforms, make strategic changes to green, intelligent, and high-quality directions, realize innovation-driven development, and technology leads the future.

　　Innovation helps the green development of technology

　　Green development is the only way for the development of the iron and steel industry. To achieve green development, it is necessary to control the whole process and focus on the following aspects: First, material design. It is necessary to strengthen the innovation of key common process technologies to enable the development of materials and products. Really achieve "reduction, low cost, high performance"; second, source management, we must implement a fine material policy, rely on innovative beneficiation technology, move the main window for improving the cleanliness of raw materials forward, improve the quality of pig iron, and reduce subsequent costs; The third is the production process. It is necessary to innovate each process and replace it with green production methods to realize the whole process of green production in the iron and steel industry. For example, carry out research on low-carbon ironmaking and non-blast furnace ironmaking technology, pay attention to the utilization of scrap steel and electric arc furnace steelmaking related research, pay attention to defect-free billet continuous casting technology and high-speed continuous casting technology, continuous casting billet direct rolling and full continuous Head rolling technology development, application and development of no-pickling hot-dip galvanizing technology, rapid heat treatment of cold-rolled strip steel and hot-dip galvanizing technology, etc.

　　Innovatively promote the intelligent upgrade of equipment

　　The iron and steel industry is the industry with the strongest demand for intelligence. At present, the whole-process integrated intelligent control and coordination optimization has not yet been formed. The steel industry is a process industry, and the core task of intelligent manufacturing is to establish a virtual mapping of CPS (cyber-physical system) with sufficient accuracy. However, the main production processes of blast furnace, converter, refining furnace, ladle, continuous casting billet, hot rolled steel, cold rolled steel, etc. are all "black boxes", and production status and parameters cannot be measured online and in real time. The current mechanism or physical model used The forecast accuracy is limited and it is difficult to further improve by traditional methods. To solve this problem, we must resort to technological innovation. The proposal of the new concept of “digital perception” provides us with new ideas and feasible methods for using modern information technologies such as big data, cloud computing, and artificial intelligence to overcome previously insurmountable obstacles. Precise sensing and control provide ideal solutions to achieve precise coordinated control of intelligent systems and equipment and further intelligent optimization decisions.

　　Innovation promotes high-quality product transformation

　　The high-quality transformation of steel products is through innovation, and on the basis of in-depth study of the tetrahedral relationship of "composition, process, organization, and performance" of materials, with "reduction, low cost, and high performance" as the new concept of material research and development. , Focusing on the following aspects: one is upgrading traditional materials, reducing alloy content, adopting advanced technology, reducing resource and energy consumption, and conventional products moving towards mid-to-high end, creating "first"; second, innovative development of high-tech materials, Achieve large-scale production, play a leading role, and create a "only"; third is to overcome key high-end materials to meet the needs of major projects such as national defense and military industry; fourth is to focus on expanding composite materials, expanding the application of steel materials in the field of composite materials, and improving materials usage efficiency. At the same time, for high-quality products, it is necessary to develop high-quality production processes and supporting production equipment to optimize the entire process of smelting, refining, continuous casting and rolling and heat treatment, and to achieve mass production and industrial application of high-quality products. .

　　Innovation to accelerate the process of supply service

　　Improving the quality and level of service and building a service-oriented steel industry is our direction. Driven by market and user needs, grasp the essence, actively innovate, and provide users with full-process technical services and overall solutions including material research and selection, product manufacturing, equipment debugging, and mass production applications. Baosteel’s EVI cooperation model for automotive sheets and the industrialization of 2GPa hot stamping steel developed by Northeastern University in Benxi Iron and Steel are worth learning.

　　my country’s economic development has entered a new era. The high-quality development of the iron and steel industry has a long way to go. Relying on innovation, focusing on the development of green, intelligent, high-quality, and service-oriented new technologies, new processes, new equipment, and new products is our construction of steel The only way to a strong country. It is hoped that World Metal Herald will strengthen its innovative technology coverage in 2019, play its role in guiding public opinion in the technical field of the steel industry, and contribute to the realization of high-quality development of the steel industry.
