Abstract：

According to processing characteristics of roll forming-forging process of valve blank,several kinds of performing blank with different initial diameters for finish forging were designed.Local upsetting finish forging process was simulated by DEFORM-2D,and some deforming rules on metal flow,strain distribution and lengthening of valve rod were obtained.Design principle of performing blank was presented based on the relation between rod lengthening and dimension of blank and deforming conditions.Finish forging experimental proves correctness of performing blank design,and experimental results show that roll forming-forging process can produce high quality valve blanks.
