在严格执行国家标准及行业标准规定下,大连金鼎石化公司成功地制造了10m3国内体积最小的高强钢原级球罐,实现了国产化,填补了国内空白。本文主要从弹塑性变形和球罐组焊两大方向阐释了球罐制造技术要点及成型控制措施。对今后标准计量型球罐研究工作及提高制造技术水平都有一定的指导作用。
Under the strict implementation of the national standards and industry standards, Dalian Jinding Petrochemical Company successfully manufactured the 10m3 domestic smallest-volume high-strength steel primary-level spherical tank and achieved its localization and filled the domestic blank. In this paper, the main points of spherical tank manufacturing technology and forming control measures are explained from the two directions of elastic-plastic deformation and spherical tank welding. The future standard measuring spherical tank research and improve the level of manufacturing technology have a guiding role.
