摘　　要：运用冶金流程工程学观点,并结合工厂应用实例对小方坯热送热装技术、直接轧制技术和铸轧型无头轧制技术的发展和应用进行了介绍。以小方坯连铸-轧钢制造流程为例,讨论了冶金制造流程中时间、空间等关键要素的配置方法对整个流程中能量耗散的影响,研究了冶金流程典型耗散系统中物质流、能量流和信息流实现"层流"运行的关键技术以及应用效果。通过理论分析和工厂实例,证明通过优化连铸-轧钢"界面"衔接,建立物质流、能量流、信息流优化的运行网络并且实现高效运行,可以显著降低整个棒线材生产流程的能量耗散,节约大量能源,从而实现降本增效、节能减排、绿色化生产。In this paper,the development and application of hot delivery and charging,direct rolling and endless rolling technology of casting-rolling of billet are introduced with the view of metallurgical process engineering.Taking the process of billet continuous casting and rolling as an example,the key elements which influence the energy dissipation of the process were studied and the key technologies to realize"laminar flow"operation of material flow,energy flow and information flow in the typical dissipative system of the metallurgical process were discussed.Through theoretical analysis and factory examples,it is proved that by optimizing the"interface"connection of continuous casting and rolling,establishing the optimized operation network of material flow,energy flow,and information flow and realizing efficient operation,the energy dissipation of the whole process can be significantly reduced,a large number of energy sources can be saved,to realize cost reduction,efficiency increase,energy conservation,and emission reduction,and green production.
