Influencing Factors on Finishing Temperature of Strip During Continuous Hot Rolling

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.
