大型工業軋機的三維板帶軋制解析

Three-dimensional Analysis of Strip Rolling in a Large Production Mill

  • 摘要: 針對傳統理論的不足,并考慮到板帶的橫向流動,建立了板帶軋制的三維解析模型.數值解析給出了單位軋制壓力、出口斷面形狀、邊部減薄及寬展等計算結果,且不同軋制條件下的計算實例與實際相吻合,表明所開發的三維程序適用于單機架或連軋機組等不同型式的寬、窄帶鋼軋制解析.

     

    Abstract: A 3-dimensional strip rolling analysis model considering strip lateral flow is developed in order order to overcome the disadvantages in the traditional theories. The distribution of specific rolling pressure, transverse stress, exit strip profile, edge drop and width spread are obtained by numerical calculations. Calculated examples under different kinds of rolling conditions conform to the reality, and results show that the developed 3-dimensional program is applicable for the narrow strip or wide strip, single stand or tandem mill.
