机械制造业对各种经济坯料的需求越来越增长,是迅速发展轧环工艺的原因.业已知道,这种生产工艺能保证比其他生产工艺(锻造、摸锻)获得精度更高、壁厚更薄的无缝环.而且,生产的制品具有变形组织均匀和使用性能优良的特性.由于变形区受到限制,生产过程能保证降低工作负荷,因而也相应地降低了加工设备的容量.所以,无论在苏联还是在国外,都广泛地生产各种无
The growing demand for various economic billets in the machinery manufacturing industry is the reason for the rapid development of the rolling ring process.It has been known that this production process ensures higher accuracy than other production processes (forging, swaging) Thinner seamless rings. Moreover, the products produced have the advantages of uniform deformation of the organization and the use of excellent performance.Because the deformation zone is limited, the production process can ensure reduced workload, thus correspondingly reducing the capacity of processing equipment.Therefore, No matter in the Soviet Union or abroad, they all produce a wide range of things
