    結果表明，泄漏的主要原因是焊接缺陷導致焊縫區發生縫隙腐蝕，而工作介質的局部酸性、流體的流動形態、大氣中有害物質、溫差應力等綜合作用，加上使用期過長等加劇了腐蝕，導致該塔泄漏。
  2. And it investigates the appearance condition ( including joint, crack, eroding, corrosion, braking pole device rupture, crane - girder ' s gnawing railway and so on ) of the whole crane - girder system on the spot, at the same time, it also actually examines the stress of the beam, chemical ingredient, distortion and railway excursion, etc. through sampling, and based on the actually examined results, it checks and calculates the carrying capacity of crane - girder system. then, based on the investigating on the spot and the calculated result, it discusses the mechanism of fatigue failure of the upper part of welded steel crane - girder, analyses the reason of steel crane - girder in the high - frequency emerging the fatigue crack, institutes the strengthened method of damaged steel crane - girder of accurate packing up workshop of the primary mill plant. finally, it presents some advice and suggestions for the repairing and strengthening method of fatigue crack of upper part of steel crane - girder in the high - frequency

    針對包鋼初軋廠精整車間鋼吊車樑上部區域出現裂縫這一問題，本文首先綜述了國內外關于焊接鋼吊車樑上部區域疲勞裂縫的研究現狀；其次對整個吊車梁系統的外觀情況（包括連接、裂縫、腐蝕、銹蝕、制動桿件斷裂、吊車啃軌等）進行了現場調查，抽樣實測了梁的應力、化學成分、變形及軌道偏移等，根據實測結果，對吊車梁系統的承載能力進行了驗算；然後，根據現場調查及計算結果，探討了焊接鋼吊車樑上部區域疲勞破壞的機理，分析了重級工作制鋼吊車梁出現疲勞裂縫的原因，制定了初軋廠精整車間破損鋼吊車梁的加固方案；最後就重級工作制鋼吊車樑上部區域出現疲勞裂縫的修復與加固方案提出了一些意見和建議。
  3. According to these, the paper put forward some countermeasures : select low carbon steel or low metal alloy steel with lower intensity, like 20r steel ; while welding, adopt strict craft measures with lower welding heat to input ; after jointing, proceed the whole hot dissolving on time ; control each welding joint with hardness hb 185 ; add 0. 25 % water into the liquid ammonia as decay eclipse ; enhance checking in operation, repairing equipment in time through regular interior and exterior checking

    針對上述原因提出了防止氨冷器類臨氨壓力容器產生應力腐蝕裂紋的對策：選用強度稍低，但抗裂性較好的低碳鋼和低合金鋼，如用20r鋼製造；焊接時應採用嚴格的工藝措施和較低的焊接熱輸入量；焊后應及時進行整體消除應力熱處理；控制焊接接頭各區硬度hb 185 ；在液氨中添加0 . 25 %的水作為緩蝕劑；在運行中加強檢查，及時進行停車檢修時的內外部檢查和定期檢驗。
