The distribution law of horizontal cross section area of ring forging and ring blank is put forward to describe the rolling formability of conical ring with inner steps.
Roll forgings. In roll forging, a bar stock, round or flat is placed between die rollers which reduces the cross-section and increases the length to form parts such as axles, leaf springs etc.
在滚锻时，圆的或是扁平的棒料放在模辊之间缩小横截面增加长度制成诸如轮轴、板簧之类的零件。
