Hauv kev tsim khoom niaj hnub, twj lag luam cov peev txheej steel ua si lub luag haujlwm tseem ceeb. Lawv tau dav siv nyob rau hauv ntau lub twj manufacturing liaj teb nrog siab heev thiab kev ua haujlwm siab. Txawm li cas los xij, kom ntseeg tau lub sijhawm ntev thiab ruaj khov ntawm cov cametings no, lub voj voog tsim nyog yog qhov tseem ceeb.
Feem ntau hais lus, tshiab tau ua cov cuab yeej siv steel peev txheej yuav tsum tau kuaj xyuas ntau zaus nyob rau hauv thaum ntxov tom qab tau muab siv. Feem ntau hais lus, lawv yuav tsum tau kuaj tsawg kawg ib zaug hauv thawj 1-3 lub hlis. Qhov no yog feem ntau vim tias nyob rau hauv thawj thawj zaug siv, cov kab ke yuav muaj qee cov teeb meem me lossis cov teeb meem muaj peev xwm vim muaj kev ntxhov siab thiab kev yoog raws ib puag ncig ua haujlwm. Los ntawm kev tshuaj xyuas thaum ntxov xws li cov npoo npoo thiab cov kab nrib pleb me tuaj yeem nrhiav tau nyob rau lub sijhawm yog li coj kev ntsuas kho tau.
Raws li kev siv sijhawm dhau mus, yog tias tsis muaj kev txawv txav ntawm kev siv hluav taws xob, xws li cov pa hluav taws xob siab, lub voj voog siab yog tuaj yeem txuas ntxiv mus txog li ib nrab ib nrab. Nyob rau theem no, nws yog ib qho tsim nyog kom tau them sai sai rau kev ua tau zoo tag nrho ntawm kev ua tiav, xws li seb lub hardness, kev ua kom nruj thiab lwm yam ntsuas muaj qis dua.
Rau Tool Steel Investment Castings siv nyob rau hauv ib puag ncig ua haujlwm, kev txij nkawm txij nkawm yuav tsum tau ua kom luv ntxiv. Piv txwv li, hauv cov khoom siv hauv kev lag luam xws li tshuaj lom thiab mining, kev saib xyuas txhua lub hlis peb lub hlis lossis txawm tsawg heev. Kev saib xyuas kev ua haujlwm feem ntau suav nrog kev ntxuav tu impurities thiab impurities nyob rau saum npoo ntawm lub Casting, thiab kho cov khoom ntawm cov khoom tseem ceeb yog tias tsim nyog.
Lub voj voog tsim nyog txij nkawm rau cov cuab yeej steel peev txheej tsis tuaj yeem tsuas yog siv cov nqi zoo thaum siv thiab ua kom qhov kev kawm tau zoo ntawm cov haujlwm ntau lawm. Yog li, kev nkag siab thiab ua raws li kev paub txog kev saib xyuas txij nkawm yog qhov tseem ceeb rau cov tuam txhab uas siv thiab tsim cov cuab yeej steel peev me.
