Study of Short Stroke Control Model on Hot Rolling Mill

摘要

Head and tail width defects have a negative effect on hot strip quality. This paper developed a short stroke control (SSC) model to improve the width accuracy of head and tail. The model established a database to store the data of feature points, according to the steel grade and the working condition. This paper Fitted the polynomial control curves with the feature points by the least square method, and executed the control curves on the vertical rolling. The results indicate that the model is useful for strip ends width control.
