Intelligent manufacturing as the engine to drive the iron and steel industry three major changes

The iron and steel industry is a process manufacturing industry with a high degree of automation and a good information foundation, and intelligent manufacturing is an important engine to promote the quality change, efficiency change and power change of the iron and steel industry and achieve high-quality development. During the "13th Five-Year Plan" period, the key technologies of intelligent manufacturing have been continuously deepened in the steel industry, effectively improving the steel production efficiency, product quality and enterprise management level. In December 2021, the Ministry of Industry and Information Technology and other departments have issued a number of important policy documents such as the Guide to the Construction of the National Intelligent Manufacturing Standard System (2021 version), the "14th Five-Year Plan" intelligent manufacturing Development Plan, the "14th Five-Year Plan" Raw material Industry Development Plan, pointing out the direction for promoting the integration and innovation of "intelligent + traditional manufacturing industry".

Recently, the Ministry of Industry and Information Technology and other three ministries jointly issued the "Guiding Opinions on Promoting the high-quality development of the steel Industry" (hereinafter referred to as the "Guiding Opinions"). As an important policy document guiding the development direction of the steel industry "14th Five-Year Plan", the "Guiding Opinions" put forward specific requirements for intelligent manufacturing to promote the high-quality development of the steel industry, such as demonstration and promotion, data sharing, demand guidance, and standard guidance, which are coordinated with the previous important policy documents related to intelligent manufacturing and raw materials. It further clarified that intelligent manufacturing, as a powerful engine for innovation and development, bears the important mission of driving the steel industry to improve product quality, improve production efficiency, reduce production costs, reduce safety and environmental protection pressure, and release the vitality of human resources.

First, the "Guiding Opinions" put forward the quantitative objectives and main tasks of intelligent manufacturing

The "Guiding Opinions" put forward the quantitative goal of the "14th Five-Year Plan" intelligent manufacturing innovation and development of the steel industry, that is, by 2025, the numerical control rate of the key processes in the steel industry will reach about 80%, the digitalization rate of production equipment will reach 55%, and more than 30 smart factories will be built. The main tasks include:

(1) Demonstration and popularization. In the iron ore (949, -17.00, -1.76%) mining, iron and steel production field breakthrough a number of intelligent manufacturing key common technologies, select a number of promotion application scenarios, cultivate a number of high-level professional system solution suppliers, build a number of intelligent manufacturing demonstration factories.

(2) Data sharing. Build a big data center for the steel industry to improve data resource management and service capabilities. Rely on leading enterprises to promote multi-base collaborative manufacturing, and realize the optimization of the whole industrial chain under the framework of the industrial Internet.

(3) Demand guidance. Enterprises are encouraged to vigorously promote smart logistics, further promote user-centered service-oriented manufacturing, and carry out large-scale customization, remote operation and maintenance services, networked collaborative manufacturing, e-commerce and other new business forms to raise the added value of products and services.

(4) Standard guidance. Build a standard system for intelligent manufacturing in the steel industry, and actively carry out research on basic commonalities, key technologies and industry application standards.

Second, the development status and key issues of steel intelligent manufacturing

During the "13th Five-Year Plan" period, the iron and steel industry took intelligent manufacturing as the main direction of "the deep integration of the two", a number of intelligent manufacturing key common technologies in the application of iron and steel production scenes achieved remarkable results, a number of intelligent manufacturing, industrial Internet projects were selected by the Ministry of Industry and Information Technology pilot demonstration and new model special, the industry intelligent manufacturing standardization work was fully launched. The cognition and application level of key technologies of intelligent manufacturing on both sides of supply and demand have been significantly improved.

1. Development status

During the "13th Five-Year Plan" period, iron and steel enterprises have focused on the research of intelligent equipment, big data, artificial intelligence, digital twin, mobile Internet of Things, industrial network security and other technologies, and actively explore the application of new intelligent manufacturing technologies in design and development, energy control, quality control, production and operation. Steel production enterprises have further improved the construction of five-level information systems for basic automation, process control, manufacturing execution, enterprise management and decision support; Enhance the digitalization and intellectualization of the whole process of the enterprise; Promote the development and implementation of industrial Internet and industrial big data platforms; It has promoted the use of robot technology in positions with harsh environment, high safety risk and high operation repeatability.
