Lojcov iav nplhaibyog ib qho tseem ceeb hauv ntau yam kev siv hauv kev lag luam, suav nrog cov tshuab hnyav, cov khoom siv mining thiab cuacov turbines. Cov txheej txheem ntawm kev tsim cov iav loj loj muaj ntau kauj ruam tseem ceeb kom ntseeg tau tias lawv zoo, ruaj khov, thiab raug.

1. Kev xaiv cov khoom siv raw zoo. Feem ntau, cov chaw tsim khoom siv cov hlau sib xyaw lossis cov hlau carbon kom ntseeg tau tias cov iav tuaj yeem tiv taus hnyav
cov khoom thauj thiab cov xwm txheej ua haujlwm hnyav. Cov khoom siv xaiv tom qab ntawd raug tshuaj xyuas kom zoo rau txhua qhov tsis zoo lossis cov khoom tsis huv ua ntej ua tiav

ntxiv mus.

2. Ua ntau yam txheej txheem machining kom nws zoo li daim ntawv xav tau. Qhov no suav nrog kev tig, milling, thiab drilling los tsim cov

cov qauv yooj yim ntawm lub nplhaib loj iav. Kev ua haujlwm raug yog qhov tseem ceeb ntawm theem no kom ntseeg tau tias lub iav qhov ntev thiab kev kam rau ua tau raws li

cov lus qhia uas yuav tsum tau ua.

3. Kev kho cua sov. Cov txheej txheem no yog qhov tseem ceeb rau kev txhim kho cov khoom siv kho tshuab ntawm cov khoom lojlub nplhaib iav, xws li qhov nyuaj thiab lub zog.

Cov txheej txheem kho cua sov xws li carburizing, quenching, thiab tempering yog siv los ua kom tiav cov khoom siv xav tau, xyuas kom meej tias

cov iav tuaj yeem tiv taus cov khoom hnyav thiab tiv taus kev hnav thiab qaug zog.

4. Ua tiav ntau yam txheej txheem tiav, suav nrog kev sib tsoo thiab honing. Cov txheej txheem no pab ua kom tiav qhov chaw xav tau thiab

qhov tseeb, ua kom ntseeg tau tias kev ua haujlwm du thiab ua haujlwm tau zoo thaum siv lub iav.

5. Yuav tsum ua raws li cov kev tswj xyuas zoo kom ntseeg tau tias nws ua tau raws li cov qauv teev tseg. Qhov no suav nrog kev tshuaj xyuas qhov ntev,

kev kuaj cov khoom siv, thiab kev kuaj tsis ua puas tsuaj kom paub txog tej qhov tsis zoo lossis qhov tsis xwm yeem.

Hauv kev xaus, cov txheej txheem tsim khoom lojcov iav nplhaibmuaj ntau kauj ruam tseem ceeb, los ntawm kev xaiv cov khoom siv mus rau kev ua kom raug,

kev kho cua sov, kev ua tiav, thiab kev tswj xyuas zoo. Txhua kauj ruam yog qhov tseem ceeb hauv kev ua kom cov khoom kawg ua tau raws li cov kev cai nruj rau

kev ua haujlwm ntev, kev ua kom raug, thiab kev ntseeg tau hauv kev siv hauv kev lag luam.
