Abstract：The proposal of "carbon peak" and "carbon neutrality" has made the concept of green steel attract widespread attention. Green steel not only refers to the excellent emission indicators and beautiful environment of iron and steel enterprises, but also means to build a low carbon and cost production line that integrates process optimization, equipment optimization, and process optimization of "three-flow collection" which ferrite flow, energy flow and information flow, achieved the goal of the lowest life-cycle cost of the enterprise from design, construction, production to elimination. The current long-process production process with the main purpose of reducing production emissions and rational recycling, through automatic steelmaking with sublance and dynamic control, integrated equipment and technologies such as scrap preheating, one tank to the end, ladle capping, alloy baking, slag detection, sliding plate slag blocking, waste heat recycling, dry primary dedusting, secondary, tertiary and scattered dedusting, and comprehensive utilization of steel slag, good results have been achieved in the projects that have been put into production, and they are still improving. In addition, when carrying out layout and process design, the natural terrain height difference of the site should be fully utilized, and attention should be paid to reducing production and operation. At the same time, production enterprises should also cultivate and establish a professional talent team for green steel production, focus on standardizing information management from production management, optimize production scheduling and process connection, and improve the efficiency of material conversion and energy conversion in the whole process. Enterprise should establish the management of material flow, energy flow and information flow focusing on the whole process from raw materials to finished products, and realize the "customized" production mode that determines raw material based on product quality. Design enterprise should aiming to build an iron and steel enterprise with the lowest life-cycle cost, develop life-cycle intelligent management software covering plant design, construction and production operation, and manage and control the cost of each stage in the life-cycle, so as to realize green steel production in the true sense.
