摘要: 為了在短時間內順利實現帶鋼規格的變換,提高變規格過程的穩定性,提出了一種等壓下系數的動態變規格規程設計策略和原理,給出了設計計算實例,與常規規程設計策略計算結果進行了對比,并對過渡過程各機架軋制力和出口厚度的波動進行了仿真計算。結果表明,新策略對提高變規格過程的穩定性,減少變規格機架對逆流機架的影響和干擾有著顯著的作用。Abstract: A strategy and principle of the optimization of pass schedule named equal reduction were first proposed in order to reduce the time of Flying Gauge Control (FGC) and improve the stability of FGC process. An actual example was given, and the changes in rolling force and gauge during FGC were simulated. The results showed that the stability of FGC process can be improved and the influence of the FGC stand on the other upriver stands can be reduced by the proposed pass-schedule strategy.
