摘　　要：对具有高成形性的热轧ＳＰ３２５深冲钢板，进行了不同终轧、卷取温度下基本成形性能指标塑性应变比Ｒ值和凸耳参数｜△Ｒ｜的检测以及深入的织构测算，结果表明终轧温度与卷取温度的不同将引起热轧板内部织构的变化，从而影响其成形性能．The deeply-drawably hot-rolled steel plate SP325 was tested at different end-rolling/coilingtemperatures for its basic formablily targets i. e.,the value of plastic strain ratio or lankform value R and lugparameter |△R| .with its texture investigated. The results showed that the changes in end-rolling and coilingtemperatures will result in the variation in texture hence in formability.
