Abstract:Improving the energy efficiency of the manufacturing process system and saving energy are important measures to reduce production costs and reduce carbon emissions. In recent years, the energy-saving work of China′s steel industry has made significant progress in the process from individual equipment energy-saving, process optimization energy-saving to systemic energy-saving. Based on the energy-saving process of China′s steel industry, the concept, connotation and research progress of system energy saving were expounded, the future development direction, and mainly starts research from collaborative matching of processes and interfaces, coupling of material flow and energy flow, and construction of industrial ecological link systems were discussed. Under the guidance of system energy-saving theory and metallurgical process engineering theory, the energy-saving and emission reduction of China′s steel industry will be promoted, the systemic energy efficiency of the steel manufacturing process will be significantly improved, and the coordinated development, transformation and upgrading of green and intelligent iron and steel industry is just around the corner.
