    不銹鋼無縫管加工過程中斷裂原因簡(jiǎn)析

    Analysis of Causes for Rupture of Seamless Stainless Steel Tube during Processing

    • 摘要: 通過對(duì)不銹鋼無縫管坯料質(zhì)量、加熱制度的分析以及管坯在熱穿孔、酸洗和冷加工過程中發(fā)生斷裂的宏觀形貌的觀察,分析了不銹鋼無縫管加工斷裂的原因。指出合理地選擇加工工藝和嚴(yán)守操作規(guī)程將減少鋼管加工中的斷裂。提出了防止不銹鋼管加工中發(fā)生斷裂的一些具體措施。

       

      Abstract: Analyzed are the causes for rupture of the seamless stainless steel tube during processing, involving analysis of the quality and heating schedule of the blank, observations of the macro-morphologies of rupture of the mother tube occurring in the processes of hot-piercing, pickling and cold-working. It is concluded that properly- determined processing processes and strictly following of the operation procedures will contribute to reducing ruptures of steel tubes being processed. Specific measures are proposed to prevent rupture of the stainless steel tube during processing.
