摘要： 炼钢厂系统是钢铁制造过程系统的一个重要子系统，其制造过程的复杂性、过程控制的艰巨性是钢铁制造过程多维物质流管制最集中的体现. 炼钢区段的优化与控制是钢铁制造过程系统运行控制的关键. 在总结以往炼钢厂物质流管制研究工作的基础上，从理性角度对炼钢厂系统的运行与控制进行探索，归纳出炼钢厂系统运行优化的逻辑与实现关系，并对转炉炼钢厂系统调控策略进行补充，阐述了炼钢系厂统运行优化的层次与指导策略.

Abstract: The steelmaking workshop is an important subsystem of steel manufacturing process system, the complexity of production process and difficulty of process control are the most concentrated expression on the multidimensional mass flow control in steel manufacturing process. Optimization and control in steelmaking zone is the key point of operation control in steel manufacturing process system. On the basis of summarizing research on mass flow control in several steelmaking workshops, the theoretical approach has been done for steelmaking system operating and controlling. The relationship between logic and realization for optimized running of steelmaking workshop has been deduced, and some supplement to control strategy of steelmaking workshop has also been made. Levels and guiding strategy of system optimized running have been expounded.

Key words: E.coli HB101(pBR322), high cell density culture, plasmid stability, b-lactamase
