METHOD FOR ESTIMATING ROLLING CONDITION BY ROLLING CONDITION ESTIMATING MODEL

摘要

PURPOSE: To provide a method for estimating rolling conditions by which manpower saving and cost reduction of work are attained by a rolling condition estimating model. ;CONSTITUTION: By composing operating condition spaces after determining the section division of each operating condition, classifying the results data of rolling conditions into the operating condition spaces, combining cells in the operating condition spaces while keeping estimating accuracy and calculating the average value of the results data of rolling condition and influence model of operating condition for every cell, the estimating model of rolling condition is created. At the time of estimating the rolling condition by means of the estimating model, the operating condition cell with which the data to be first estimated is corresponding is determined and whether the operating condition cell is a cell having results or not is decided. When it is the cell having results, the actual average value of rolling condition of the operating condition cell is taken as the estimated value of rolling condition and, when it is not the cell having results, plural proximate cells having result are selected, the value which the average value of the actual value of rolling condition of the selected cells having results is weighted by the distances from these cells and averaged is taken as the estimated value of rolling condition. In this way, highly accurate estimation of rolling condition is enabled.;COPYRIGHT: (C)1996,JPO
