摘要
首先分析了矩形截面环件轧制尺寸变化规律，以此为基础证明了法兰环件轧制中存在轴向体积流动，导出了体积流动量计算式。根据轴向体积流动规律导出了法兰环件轧制尺寸变化规律和其各种轧制用毛坯的体积分配规律。分析了各种毛坯的轧制成形性，指出了法兰环件轧制用毛坯的合理形式。
At first the dimension variation law for a rolling ring with rectangular cross section is analyzed. Then the axial volume flow for rolling flange ring is demonstrated based on the dimension variation law. The volume flow amount is also calculated. The dimension variation law for rolling flange ring and the volume distribution law for its rolling blank are derived from the axial volume flow. Lastly, the rolling formability for several blanks is discussed and the rational blanks for rolling flange ring are proposed and compared with practical rolling of flange ring.
