Summary: | To allow performing more proper rolling reduction distribution by accurately estimating a TAF value in rolling consisting of a plurality of rolling passes, and to allow improvement in productivity by performing more proper rolling reduction distribution.SOLUTION: In rolling consisting of rolling passes of N passes (N≥1), there is provided a method of estimating a TAF value for estimating a TAF value to be applied to an m-th rolling pass on the basis of a water-cooling condition of a rolling member in a rolling pass up to an input side of at least m-th pass (1≤m≤N).SELECTED DRAWING: Figure 5
【課題】複数の圧延パスからなる圧延において、精度良くTAF値を推定することにより、より適切な圧下量配分を行うことを可能にする。また、より適切な圧下量配分を行うことにより、生産性を向上させることを可能にする。【解決手段】Nパス(N≧1)の圧延パスからなる圧延において、少なくともmパス(1≦m≦N)入側までの圧延パスにおける圧延材の水冷条件に基づいて、mパス目の圧延パスに適用されるTAF値を推定する、TAF値推定方法を提供する。【選択図】図5 |
