    X65 kauv submerged arc welded kab yeeb nkab yog dab tsi?

    X65 SSAW (submerged arc welded) kab yeeb nkab yog ib hom yeeb nkab hlau siv dav hauvcov kav dejkev tsim kho hauv kev lag luam roj thiab roj av. Cov yeeb nkab kab no ua ke ntawm lub zog, kev ruaj khov thiab kev ua tau zoo kawg nkaus tau ua rau nws yog thawj qhov kev xaiv rau ntau yam haujlwm thoob plaws ntiaj teb.

    Helical Welded Yeeb Nkab

    Lub zog thiab kev ruaj khov:

    Ib qho ntawm cov yam ntxwv tseem ceeb uas ua rau X65 kauv submerged arc welded kab yeeb nkab sib txawv yog nws lub zog tshwj xeeb thiab ruaj khov. Ua los ntawm cov hlau zoo, nws muaj zog tiv taus sab hauv thiab sab nraud siab. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv roj thiab roj av, ua kom ntseeg tau tias cov khoom siv hauv paus muaj kev ntseeg siab thiab siv tau ntev.

    Kev ua haujlwm ntawm cov kav dej:

    Kev ua haujlwm zoo yog qhov tseem ceeb thaum thauj cov khoom siv los ntawm cov kav dej. X65 SSAW kab yeeb nkab ua tau zoo hauv thaj chaw no, muab cov dej ntws du nrog kev sib txhuam tsawg kawg nkaus, yog li txo cov kev siv hluav taws xob thaum thauj mus los. Qhov kev ua haujlwm zoo no pab txuag cov nqi thiab txo cov kev cuam tshuam rau ib puag ncig, ua rau nws yog qhov kev xaiv zoo rau ib puag ncig.

    a. Txoj kev deoxidation yog raws li nram no:

    FF: Cov hlau uas tua tag nrho uas muaj cov khoom sib txuas nrog nitrogen txaus kom sib txuas nrog nitrogen tau (piv txwv li tsawg kawg 0,020% tag nrho Al lossis 0,015% soluble Al).

    b. Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj lom neeg qhia tias muaj tsawg kawg nkaus Al tag nrho cov ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al/N piv ntawm 2:1, lossis yog tias muaj lwm cov ntsiab lus N-binding txaus. Cov ntsiab lus N-binding yuav tsum tau sau tseg rau hauv Daim Ntawv Tshuaj Xyuas.

    Tiv taus cov chaw ib puag ncig hnyav:

    Cov kav dej sib txuas hla ntau yam ib puag ncig, suav nrog qhov chaw nyuaj thiab corrosive. X65 kauv submerged arc welded kab yeeb nkab tau ua pov thawj nws qhov zoo tshaj plaws hauv cov xwm txheej zoo li no vim nws qhov kev tiv thaiv zoo heev rau corrosion, abrasion thiab lwm yam sab nraud. Qhov kev tiv thaiv no ua kom ntseeg tau tias lub kaw lus kav dej muaj kev ncaj ncees, txo cov nqi txij nkawm, thiab txo qhov kev pheej hmoo ntawm kev xau lossis kev ua tsis tiav.

    ASD:

    Kev tswj hwm kev ua haujlwm ntawm cov kav dej kom muaj kev nyab xeeb yog qhov tseem ceeb heev. X65 SSAW kab yeeb nkab muab qhov tseem ceeb rau kev nyab xeeb los ntawm kev xa cov khoom siv zoo heev thiab qhov tseeb ntawm qhov ntev. Los ntawm kev tswj hwm zoo nruj, cov kav dej kav dej tswj hwm qhov kev ua haujlwm ruaj khov uas xav tau los tiv taus kev nyuaj siab thiab kev ua haujlwm nyuaj, ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov peev txheej.

    Xaus lus:

    Cov yeeb nkab kab X65 SSAW sawv tawm ua qhov kev daws teeb meem zoo tshaj plaws hauv kev tsim kho thiab kev saib xyuas cov kav dej.
