PROBLEM TO BE SOLVED: To precisely estimate material characteristic values of a steel belt product.SOLUTION: An actual result DB 6 stores values of manufacturing condition items including component values by components of steel strip products manufactured in the past and measured values gathered in manufacturing processes thereof and measured by respective measuring apparatuses in respective processes 12-14 of heating, rolling, and cooling, and material characteristic values as actual result data while they are related to meshes sectioning off the inside of the steel strip products. An actual value gathering device 5 gathers measured values by meshes sectioning off the inside of an object steel strip product by acquiring measured values by the respective measuring apparatuses in manufacturing processes of the object steel strip product while tracking measurement positions thereof. A characteristic value estimation part 23 of a device body 2 regards component values by components of the object steel strip product and the gathered measured values by the meshes as values of manufacturing condition items associated with the object steel strip product, and estimates material characteristic values corresponding to values of the manufacturing condition items by the meshes using the actual result data. |
