摘　　要：通过人工设定PVPC控制功能的压下深度、长度比例等参数,同时结合HGC压下速度、最大轧制速度等限制条件,来解决PVPC模型自动模式下轧制大展宽比钢板时头尾宽度不易控制的问题。应用在展宽比为2.3的钢板轧制中,钢板通条宽度的差值比自动模式下减小20mm,宽度偏差控制在25mm以内。The head and tail width were dificultly controlled of rolling big proportion spread plate with PVPC auto- matical model. So, the PVPC manual model was applied to set pressure depth, length ration of PVPC function, which were combined with HGC pressing speed, maximum rolling speed and other restrictions. The width difference of through plate was reduced 20ram, and the width deviation was controlled within 25ram by manual model.
