本文叙述了ＬＦ２合金离心铸造空心锭，变薄旋压分支母线筒体的试验研究过程。ＬＦ２合金分支母线筒体是电器高压开关的重要管路，采用离心铸坯变薄旋压成形，既可以消除筒体的纵缝、减少环缝，又能够改善尺寸精度和强度，提高电器高压开关的安全可靠性。该工艺研制的筒体，其综合性能和质量完全满足了产品技术条件的要求，为旋压工艺成形高电压开关用无纵缝筒体开辟了新的加工领域。 This paper describes the LF2 alloy centrifugal casting hollow ingot, thinning of the spinning branch busbar test research process. LF2 alloy branch busbar tube is an important high-voltage electrical switch circuit, the use of centrifugal slab thinning spin forming, can eliminate the longitudinal seam of the cylinder to reduce the girth, but also to improve dimensional accuracy and strength, improve electrical high-voltage switch The safety and reliability. The cylinder developed by the process fully meets the technical requirements of the product in terms of overall performance and quality and opens up a new processing field for forming the non-longitudinal slotted cylinder for the high-voltage switch in the spinning process.
