The Development Process And Problems Of Steel Intelligent Manufacturing

On December 9, 2021, Li Xinchuang, Secretary of the Party Committee and Chief Engineer of the Metallurgical Industry Planning and Research Institute, and a foreign academician of the Russian Academy of Natural Sciences, was invited to participate in the "2021 World Intelligent Manufacturing Conference" and made a keynote at the Intelligent Manufacturing Empowering Iron and Steel Industry Development Sub-forum The report "Bringing on the historical responsibility of technological self-reliance and self-reliance, and joining hands with the evolution of the steel intelligent service ecosystem".

1. Development status and trends of China's iron and steel industry

Iron and steel is the basic industry of the national economy and an important indicator of a country's comprehensive national strength and degree of industrialization. China's steel industry is an important support for the rapid development of China's economy. As a typical technology-intensive industry, China's steel industry takes technological innovation as the first driving force and runs through the entire development process. The integration of intelligent manufacturing and intelligent management and control is the fourth technological revolution of the steel industry. In the future, abundant resources of advanced technology application scenarios will become an important opportunity for the rise of China's steel industry. In recent years, China’s steel industry has taken ultra-low emissions as its starting point, implemented the world’s most stringent environmental emission standards, and is actively building a demonstration of low-carbon development in the global steel industry. Since its development, China's steel industry has become the most globally competitive industry in China and will lead the development of the world's steel industry for a long time.

Judging from the current operating conditions, since the beginning of this year, China's steel industry has achieved a year-on-year decline in crude steel production, steel exports have fallen, imports have increased, iron ore prices have risen to a reasonable level, and domestic steel consumption growth has slowed down. Moving towards a new stage of low-carbon development in a high-quality period, China's steel industry will be led by low-carbon, with digital drive, technological revolution, and green synergy as the trends, to reshape a new development pattern.

2. Development history and problems of steel intelligent manufacturing

The informatization development of the steel industry can be roughly divided into three stages: the first stage is the initial exploration stage, which is a single application at the departmental information level; the second stage is the rapid development stage, which is the comprehensive integration of the enterprise information level; The stage is the mature transformation stage, which is the intelligent enhancement of the in-depth information level.

In recent years, the level of integration of the two industrializations in China's steel industry has been significantly improved, from 47.7 in 2015 to 54.3 in 2020, an increase of 13.8%, and efforts have been made to create pilot demonstrations of smart manufacturing, new models of smart manufacturing, and pilot demonstrations of industrial Internet applications . However, the current development of the integration of the two industrializations in China’s steel industry still faces a series of problems, including: weak enterprise intelligent manufacturing foundations, serious information islands; high complexity of industrial mechanisms and difficulty in building digital models; insufficient control of core intellectual property rights, and primitive The proportion of innovative applications is not high.

3. New requirements and new practices of intelligent steel manufacturing

Big data is a new stage of informatization development. Under the guidance of policies, China's smart manufacturing has entered a new stage of "data utilization". The “Fourteenth Five-Year Plan for the Deep Integration of Informatization and Industrialization Development Plan” released a few days ago has clarified the direction and outlined the key points for the digital transformation of the Chinese steel industry. The Chinese steel industry will focus on the inefficiency of equipment maintenance, the black-box production process, and downstream Demand fragmentation and increased pressure on environmental protection, and other pain points, use process optimization as the starting point to accelerate digital transformation in the direction of intelligent equipment operation and maintenance, transparency of production processes, globalization of supply chain coordination, and clean environmental management. At the same time, under the background of "dual carbon", the intelligent manufacturing of China's steel industry is also facing new requirements. It will conduct dynamic energy consumption monitoring and energy consumption analysis of high energy-consuming equipment in the steel production link, and establish an energy plan, evaluation, balance and The energy management center of predictive model improves energy efficiency and management level, and helps industries and enterprises to save energy and reduce carbon.

At present, China's steel industry and enterprises are deepening their smart manufacturing practices based on the significant improvement in the integration of industrialization and industrialization during the 13th Five-Year Plan. In view of the development of intelligent manufacturing in China's steel industry during the 14th Five-Year Plan period, it is recommended to continue to deepen the use of data, with the goal of maximizing benefits, real-time services, intelligent decision-making, and visualization of operations, and the construction of a new generation of intelligent steel management and control center as the focus of intelligent manufacturing , While solving the problem of information islands through the intelligent management and control center, it promotes the in-depth utilization of data. Under the requirements of green, low-carbon and high-quality development, in order to promote the realization of China’s steel “dual-carbon” goals, the Internet, big data, artificial intelligence, blockchain and other technologies should also be used to build at the regional, industry, and enterprise levels. Low-carbon control and evaluation platform for the whole steel process.
