摘　　要：连铸-轧钢区段作为界面模式的组成部分之一,对钢铁生产流程有重要的影响。随着热送热装技术的深入应用,工序装置之间的衔接、匹配由数量、生产能力等的匹配发展为生产节奏的匹配。其中加热炉的出坯节奏决定了轧钢的轧制节奏,从而对整个区段的节奏产生影响。对沙钢集团永新钢轧厂连铸-轧钢区段铸坯进加热炉前等待的时间间隔进行统计分析,并以排队理论为指导,对铸坯进入加热炉前的时间间隔进行优化,提出了合理的时间值,为企业的生产管理提供了理论依据。CC-rolling section as one of the components of the interface model,have an important influence on steel production process.With the hot charging technology in-depth application,the matching between the process devices was from the quantity,production capacity to the production rhythm.The billet rhythm of heating furnace decided to roll the rolling rhythm,thus affecting the rhythm of the entire section.The time interval of CC-rolling section of Shagang Yongxin Steel Mill was analysed,the time interval that the billet enters the furnace was optimized guided by queuing theory,and reasonable time value was put forward,which provided a theoretical support for the management.
