摘　　要：针对槽钢初轧孔型优化过程中因工艺设计缺陷出现的各种问题,对轧制过程进行模拟轧制计算,为孔型设计提供孔型充满度、金属位移流动规律并提出优化建议。结果显示:矩形坯料在开坯孔型的充分夹持有利于实现开坯切分;槽钢孔型内侧R角位置的金属最为活跃,可以平衡调节腿部与腰部金属位移;槽钢"假腿"设计不仅可作为腿部尺寸平衡,也利于腿部金属的增加。According to some problems caused by process design defects in primary pass optimization of channel section blooming, the simulation calculation is made for rolling process and the pass filling degree and the rule of metal displacement for pass design is provided and the optimization propose is put forward. The results showed that fully clamping of rectangular bloom in the breakdown pass is benefit to realize breakdown segmentation; The metal in angle point of the inside arc of channel section pass is the most active, which can balance the metal displacement between the flange and web; The channel section counter flange design can be not only to balance the flange size, but also benefit to increase flange metal.
