プロセスラインにおけるストリップの繰り返し曲げ変形挙動の解析とその応用

Analysis of Sheet Metal Deformation under Repeated Bending in Processing Lines and Its Application

比良 隆明(Takaaki Hira) 阿部 英夫(Hideo Abe) 東 将(Susumu Azuma) 要旨 : 近年鋼板の平坦度に対する要求が一層厳しくなり，これに対処するべく圧延における形状 制御のほかに，テンションレベラーや各ストリッププロセスラインでの平坦度制御の重要 性が増大している。その設備仕様の決定，操業条件の最適化を目的として繰り返し曲げ変 形挙動を理論的に解析し，これらの問題を汎用的に取扱える汎用計算シミュレーションプ ログラムを作成した。本プログラムを(1)テンションレベラーにおける反りの発生と残留応 力，(2)テンションレベラーによる局部伸びの矯正能力，(3)連続塗装ラインにおける反りの 矯正技術に適用し，反りを防止する方法，残留応力および局部伸びを減少させる方法等に ついて述べ，その有効性を示した。 Synopsis :

To meet customer's demand,precise flatness control has recently been required not only for strip rolling but also for strip processing lines,namely,tension levelling,coating,galbanizing, etc. Strip deformation caused by repeated bending with stretching in the processing line is analysed on the basis of incremental-strain theoly for the purposes of designing plant specifications and optimization of operation.The developed calculation program can be widely used for analyses as follows:(1)Calculation of curling and residual stresses of strip in longitudinal and width directions after tension levelling,(2)correcting-behavior analysis of edge and center waves of strip during tension levelling,and(3)calculation of strip gutters in the continuous color paint coating line.Calculated results give us a great deal of useful information for preventing curling,improving steepness and reducing residual stress of strip.
