    Cov txiaj ntsig ntawm cov kav dej sib txuas ua ke hauv cov kav dej tseem ceeb:

    1. Muaj zog thiab ruaj khov dua:

    Cov thev naus laus zis vuam siv rau hauv cov kav dej no tsim cov qauv txuas ntxiv mus, tsis muaj qhov sib txuas nrog lub zog zoo dua thiab tiv taus cov kev ntxhov siab sab hauv thiab sab nraud. Tsis tas li ntawd, cov xov sib txuas sib txuas ua rau cov kav dej ruaj khov dua, txo qhov kev pheej hmoo ntawm kev xau lossis tawg. Qhov kev ruaj khov no ua kom ntseeg tau tias koj cov kav dej loj siv tau ntev, txo cov nqi kho thiab hloov pauv.

    2. Kev tiv thaiv xeb:

    Cov kav dej tseem ceeb raug ntau yam teeb meem ib puag ncig, suav nrog cov dej noo, tshuaj lom neeg thiab av. Cov kav dej sib txuas ua ke feem ntau yog tsim los ntawm kev siv cov khoom siv tiv taus xeb xws li hlau tsis xeb, ua kom muaj kev tiv thaiv zoo tiv thaiv xeb, kev yaig, thiab lwm yam kev xeb. Qhov kev tiv thaiv no ua rau cov kav dej siv tau ntev, tiv thaiv kev puas tsuaj thiab tswj cov dej kom zoo.

    3. Kev siv nyiaj tsim nyog:

    Kev nqis peev rau cov kav dej welded spiral raucov yeeb nkab dej tseem ceebstuaj yeem ua pov thawj tias yog ib qho kev xaiv uas pheej yig rau lub sijhawm ntev. Nws cov qauv ruaj khov thiab kev tiv thaiv xeb txo qhov zaus ntawm kev kho thiab hloov pauv, yog li txuag tau cov nqi txij nkawm tseem ceeb. Tsis tas li ntawd, lawv yooj yim rau kev teeb tsa, lub teeb yuag, thiab txo qhov xav tau kev txhawb nqa ntxiv, ua rau lawv yog ib qho kev xaiv yooj yim thiab pheej yig rau cov haujlwm plumbing loj.

    4. Kev Ywj Pheej thiab Kev Siv Tau Ntau Yam:

    Cov yeeb nkab uas vuam ua ke muaj qhov yooj ywm thiab siv tau ntau yam. Lawv tuaj yeem tsim tau ntau yam txoj kab uas hla, ntev thiab tuab, ua rau lawv hloov kho kom haum rau cov kev xav tau tshwj xeeb ntawm cov haujlwm. Qhov kev hloov pauv no ua rau lawv hloov kho tau rau ntau thaj chaw thiab ntau yam av, ua rau lawv yog qhov kev xaiv zoo rau cov yeeb nkab xa dej tseem ceeb hauv nroog thiab thaj chaw nyob deb nroog.

    5. Kev ruaj khov ntawm ib puag ncig:

    Ntxiv rau lawv cov txiaj ntsig zoo ntawm kev ua haujlwm, cov kav dej sib txuas ua ke kuj tseem ua rau muaj kev pabcuam zoo rau kev ruaj khov ntawm ib puag ncig. Cov ntaub ntawv siv hauv nws txoj kev tsim kho yog cov khoom siv rov ua dua tshiab, txo cov pa roj carbon tag nrho. Tsis tas li ntawd, nws txoj kev tsim kho tsis muaj qhov tsis zoo txo ​​qhov dej poob vim yog qhov xau, yog li tiv thaiv cov peev txheej muaj nqis no.

    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.

    Xaus lus:

    Kev ua kom koj cov kav dej tseem ceeb ua haujlwm tau zoo thiab ruaj khov yog qhov tseem ceeb rau kev ua kom muaj dej txaus. Kev siv cov yeeb nkab vuam sib txuas hauv cov noyeeb nkab cov kabmuaj ntau yam zoo, suav nrog kev muaj zog ntxiv, kev tiv taus xeb, kev siv nyiaj tsim nyog, kev ywj pheej thiab kev ruaj khov ntawm ib puag ncig. Thaum peb ua haujlwm los tsim cov chaw tsim dej uas ruaj khov thiab siv tau zoo, kev nqis peev rau hauv cov thev naus laus zis siab heev xws li cov yeeb nkab vuam sib txuas yog qhov tseem ceeb heev.
