摘　　要：针对济钢1700mm热连轧生产线原层流冷却卷取温度控制系统中存在的不足和弊端,通过采用数学模型,开发多种冷却策略,修正带钢速度变化,抛钢后处理,采用反馈控制,开发模型维护工具等措施对层流冷去系统进行改造。系统改造后稳定可靠,卷取温度命中率有了较大幅度的提高。For Jinan Steel＇s 1 700 mm hot rolling production line of the original laminar cooling coiling temperature control system deficiencies and drawbacks,through the use of more advanced mathematical models,develop a variety of cooling strategies,the amendment changes the speed strip,cast steel,after processing,the use of feedback control,maintenance tools and other measures to develop models of laminar flow cooling system to transform. After transformation,the system is stable and reliable. Coiling temperature hit rate has been more substantial increase.
