发明名称 ROLLING LOAD ESTIMATION DEVICE AND ROLLING LOAD ESTIMATION METHOD OF ROLLING MACHINE
摘要 PROBLEM TO BE SOLVED: To highly accurately estimate a rolling load required for rolling a rolling object material to a desired plate thickness even when the draft ratio is small.SOLUTION: A process computer 8 discriminates whether or not the draft ratio of a rolling machine is a predetermined value or less, and when the draft ratio of the rolling machine is the predetermined value or less, a database server 9 extracts the past rolling condition data on which similarity to rolling condition data for estimating the rolling load is the predetermined value or more, and makes a regression expression for indicating the relationship between the rolling load and the rolling condition data by a regression calculation of using the extracted past rolling condition data and the rolling load associated to its rolling condition data, and estimates the rolling load by inputting object rolling condition data for estimating the rolling load to the made regression expression.
