　　1、高(gao)鉻35crmo圓鋼的(de)傾斜(xie)度(du)和橢圓形度(du)因為鋼卷(juan)全過(guo)程(cheng)中的(de)傾斜(xie)度(du)誤差(cha)，35crmo圓鋼縱縫區電焊(han)焊(han)接的(de)部分形變等要素，將(jiang)無法(fa)確保的(de)誤差(cha)，采用以下對策給予確保。

　　①設計(ji)方案生(sheng)產制造縱縫部分傾斜(xie)度校準機(ji)(ji)，縱縫電焊(han)焊(han)接后歷經校準機(ji)(ji)校準，保證其部分傾斜(xie)度誤差(cha)。

　　②設定有(you)效的高鉻35crmo圓鋼內(nei)支撐(cheng)點(dian)保(bao)證35crmo圓鋼形(xing)(xing)變值，確保(bao)35crmo圓鋼的橢圓形(xing)(xing)度。

　　2、為確保35crmo圓鋼拼裝時的豎直度及總體誤(wu)差，采用下(xia)列對策。

　　①改(gai)善(shan)焊(han)(han)(han)縫設(she)計方案，選用(yong)不一樣的X形焊(han)(han)(han)縫，沒(mei)留空隙，內縫電焊(han)(han)(han)焊(han)(han)(han)接結(jie)束(shu)后，用(yong)碳弧(hu)氣刨(bao)清根(gen)使內外(wai)雙面焊(han)(han)(han)接的具體總(zong)面積貼近相同，有益于降低形變及減少內應力。

　　②彎(wan)(wan)頭拼裝(zhuang)(zhuang)，彎(wan)(wan)頭是獨(du)特管涵，其尺寸偏差過將軍給安裝(zhuang)(zhuang)產生(sheng)一定(ding)的艱(jian)難，因而規定(ding)總體拼裝(zhuang)(zhuang)。

　　③接(jie)(jie)管連接(jie)(jie)方式 ——在滾焊(han)臺車里，先總(zong)體(ti)調節空隙、錯牙，開展總(zong)體(ti)規格查驗，檢測達標(biao)后總(zong)體(ti)一次焊(han)接(jie)(jie)。

　　④改善焊(han)接(jie)方法——采用(yong)小范疇電焊(han)焊(han)接(jie)，非常是第一層(ceng)的電焊(han)焊(han)接(jie)，提升電焊(han)焊(han)接(jie)層(ceng)級，為此降低電焊(han)焊(han)接(jie)形變量，降低35crmo圓(yuan)鋼(gang)尺寸的誤差(cha)。
