摘　　要：鉴于某钢厂深冲钢炼钢区段运行效率较低、能量耗散较大、过程稳定性较差等问题,对炼钢区段各工序内时间-事件进行解析,协调优化各工序作业时间;并结合生产线特点,构建“一对一”层流专线化生产路径。生产实践表明:采用专线化层流运行模式生产深冲钢,可避免前、后工序间交叉运行时铁素流在空间、时间、能耗上的不确定性;工序间链接时间缩短,炼钢区段总作业时间从247.9 min缩短至193.5 min;过程能量耗散减少,转炉终点温度从1671.7℃降至1653.9℃。In view of the problems such as lower operation efficiency,larger energy dissipation and poor process stability in the production process of deep drawing steel in the steelmaking section in a steel plant,the time-events in each process of the steelmaking section were analyzed,and the operation time of each process was coordinated and optimized.A“one-to-one”laminar flow dedicated production path was constructed in combination with the characteristics of the production line.The production practice showed that(a)the use of special line and laminar flow operation mode to produce deep drawing steel can avoid the uncertainty of iron element flow in space,time and energy consumption during cross operation between the former and the latter processes;(b)the linkage time between processes was shortened,and the total operation time of the steelmaking section was shortened from 247.9 to 193.5 min;and(c)the process energy dissipation was reduced,and the end-point temperature of the converter was reduced from 1671.7 to 1653.9℃.
