Innovation and practice of engineering design for new generation steel plant
The iron and steel manufacturing process is a manufacturing system integrated through the coupling of multiple procedures.Its physical essence lies in the fact that the ferrous substance flow,driven and influenced by the energy flow,undergoes a series of complex physical and chemical conversions or transformations to produce steel products.The substance flow,energy flow and information flow are mutually coupled and operated in synergy in the process,and dynamic operation is the predominant characteristic of the process.The steel manufacturing process operates far from an equilibrium state,characterized by nonlinear coupling and being an open irreversible process that entails the dissipation of matter and energy.The steel metallurgy engineering design is a systematic integration and optimization endeavor based on research findings in fundamental science,technical science,and engineering sci-ence pertinent to steel plant design.Contemporary steel metallurgy engineering design is guided by principles of en-gineering philosophy as well as metallurgical process engineering theory.It involves the judicious selection and sys-temic integration of metallurgical processes and technical equipment to establish a rational workflow with advanced structures,optimized functions,efficient operations,and competitive engineering solutions.At its core,contempo-rary steel manufacturing engineering design aims to achieve integrated objectives encompassing systematization,structuring,functional enhancement,high efficiency,sustainability,greenization,and intelligence throughout the entire project while pursuing structural integrity,functional efficacy,operational efficiency,and multi-objective op-timization within the metallurgical processes.The connotations and methods of concept design,top-level design and dynamic precise design of the new generation steel plants are discussed,and the innovation and practical effects of the engineering design of Shougang Jingtang Steel Plant are expounded.
