  By the end of 2020, the Ministry of Industry and Information Technology will openly solicit opinions on the "Guidance on Promoting High-quality Development of Iron and Steel Industry (Draft)" (hereinafter referred to as the "Opinions"). The "Opinions" put forward that by 2025, the iron and steel industry will basically form a development pattern of reasonable industrial layout, advanced technology and equipment, outstanding quality brand, high intelligence, strong global competitiveness, green, low-carbon and sustainable development. The "Opinions" put forward higher requirements for the development of iron and steel industry during the "14th five-year plan".

  During the "14th five-year plan" period, how can the iron and steel industry achieve higher quality development in the field of intelligence and greenness? In terms of this, Mr. Gan Yong, chairman of China Society of Metals and academician of Chinese Academy of Engineering, deeply interpreted the current situation of intelligent and green development of iron and steel industry, and pointed out the existing problems and breakthrough direction in the field of intelligent and green development of iron and steel industry.

  "Intelligent manufacturing will be the main method of technological innovation and transformation during the" 14th five-year plan ". China has become a global metallurgical production and consumption center, and should further become a global center of education and research and development. " Gan Yong pointed out.

  "Intelligent manufacturing is a large-scale system of deep integration of advanced information technology and manufacturing technology. It is a large-scale system composed of three functional systems of intelligent products, production and industrial mode (intellectualization of industry and industrial chain) and the supporting system of industrial Internet." Gan Yong defines intelligent manufacturing in this way.

  How to realize intelligent production in iron and steel enterprises? Gan Yong gives the following suggestions:

  Firstly, build a real-time perception, digital and industrial Internet system, collect data such as output, quality, energy consumption, processing accuracy and equipment status in time, associate with orders, processes and personnel, and trace the whole production process. Secondly, develop special image processing technology under complex conditions. Thirdly,  establish a high-precision composite model or simulation center, as well as the whole process integrated control system. Fourthly, build intelligent operation and maintenance system of process equipment, including health monitoring and intelligent maintenance system of large-scale key equipment, cross regional, industry and platform equipment operation and maintenance cloud platform, as well as remote response mechanism and supporting service system of equipment operation and maintenance.

  During coronavirus pandemic in 2020, Baosteel Group, through remote operation and maintenance, big data and artificial intelligence, transformed the hot dip galvanizing intelligent workshop of cold rolling mill in Baoshan base of Shanghai into one factory that do not need more than one person to operate for 24 hours. And when the production line encounters technical problems, engineers can solve problems at home via mobile phones. By apps on the mobile phone, the relevant staff can not only clearly see the operation status of Baoshan base in Shanghai, but also the Zhanjiang base of Baosteel 3000 km away, truly achieving "no face-to-face production." Taking the intelligent hot galvanizing workshop of Baosteel cold rolling plant as an example, Gan Yong introduced how to use intelligent manufacturing to realize remote production.
