2000m~3球罐是我国石油工业球罐制造史上容积最大的球罐。该球罐在制造中吸取了国外球罐制造的先进技术,对传统的制造工艺进行了彻底改革,球壳板成型采用冷冲压技术;球壳板净料切割由过去的用单嘴氧-乙炔切割机在立式固定胎架上多次切割,改为用四嘴氧-丙烷切割机在卧式平衡台架上一次切割;研制了四嘴氧-丙烷自动跟踪切割机和球壳板卧式平衡台架等专用设备。该项新工艺提高工效1～1.5倍,加快了制造进度,球罐制造质量显著提高。本文着重介绍了球壳板的制造技术及成果检验。该项产品获河南省1989年优质产品称号,该项制造技术获中国石油天然气总公司1989年科学技术进步二等奖。
2000m ~ 3 spherical tank is China’s oil industry in the history of the largest spherical tank manufacturing spherical tank. The spherical tank in manufacturing draw on the advanced technology of foreign spherical tank manufacturing, the traditional manufacturing process has been completely reformed, spherical shell molding using cold stamping technology; ball shell net material cutting by the past with a single lipoxy - acetylene Cutting machine in the vertical fixed tire rack cut multiple times, instead of using four mouth oxygen - propane cutting machine in a horizontal balance on a cutting stage; developed a four-mouth oxygen - propane automatic tracking cutter and ball shell horizontal Balance bench and other special equipment. The new technology to improve ergonomics 1 to 1.5 times, speeding up the manufacturing progress, significantly improve the quality of manufacturing spherical tank. This article focuses on the manufacture of spherical shell plate and test results. The product won the title of Henan Province in 1989 the title of quality products, the manufacturing technology by China National Petroleum Corporation in 1989 scientific and technological progress second prize.
