-
摘要: 介绍了1Cr18Ni9Ti钢的3种冶炼工艺。分析了1Cr18Ni9Ti超薄壁旋压管表面产生飞刺、斑点和灰带等缺陷的原因。指出了1Cr18Ni9Ti钢的局限性。提出了消除或减少这些缺陷的改进意见。Abstract: Three metallurgical processes for 1Cr18Ni9Ti steel are described. Also investigated are the elements reponsible for the main defects of the spinned 1Cr18Ni9Ti steel extra-light wall tube such as fin, spot and grey strip etc, and the limitation of the said steel.At last, relevant measures to eliminate or at least reduce the above mentioned defects are proposed.
