摘要： 在传统传热模型基础上开发了带钢热连轧精轧温度控制模拟软件,系统地分析了穿带速度、带钢粗轧出口温度、带钢机架间厚度、水冷换热系数和工作辊材质等7种因素对带钢精轧出口温度的影响规律;确定了影响带钢终轧温度的主要因素;使用现场实测数据对模拟软件计算精度进行了检验,表明开发的精轧温度控制模拟软件计算精度较高.为建立高精度热连轧带钢温度在线控制模型提供了理论依据.

Abstract: A simulation software was developed to research the finishing temperature of hot strip rolling, based on conventional heat transfer model. How the seven factors affect the finishing temperature of strip were systematically analyzed, including it's rolling threading speed, exit temperature of rough rolling, inter-stand thickness change, heat exchange coefficient when water cooling, the material of work roll, temperature of work roll and ambient temperature. Among them the first five were regarded as key factors. The computation accuracy of the simulation software is as high as checked and proved by the data measured actually. Thus the software provides the theoretically the reference for developing a high-accuracy on-line control model of strip temperature during continuous hot rolling.
