Title:
MATERIAL-PROPERTY-VALUE ESTIMATING METHOD, MATERIAL-PROPERTY-VALUE ESTIMATING DEVICE, AND STEEL-STRIP MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/056129
Kind Code:
A1
Abstract:
An actual-result database 6 stores actual-result data obtained by associating, with respective mesh sections that partition the inside of the steel-strip product: manufacturing-condition-item values that include component values of respective components of a steel-strip product manufactured in the past and measurement values obtained by measurement devices during steps 12-14 for heating, rolling and cooling; and material property values. An actual-result-value collecting device 5 acquires the measurement values obtained by the measurement devices while tracking the measurement positions thereof during the manufacturing process of a target steel-strip product, so as to collect the measurement values for the respective mesh sections that partition the inside of the target steel-strip product. A property-value estimating unit 23 in a device body 2 sets the component values of the respective components of the target steel-strip product and the measurement values collected for the respective mesh sections as manufacturing-condition-item values related to the target steel-strip product, and estimates material property values corresponding to the manufacturing-condition-item values for the respective mesh sections using the actual-result data.
