Qhov kev txiav txim no yog NTH xaj ntawm peb tus thawj saib xyuas Zhao cov neeg siv khoom qub hauv Australia.
Zhao tus thawj coj ntawm lub tuam txhab kev lag luam qub tub rog, nrog kev muag khoom nplua nuj thiab kev sib raug zoo ntawm cov neeg siv khoom muaj peev xwm.
Nws yog qhov zoo ntawm kev tsim kom muaj kev sib raug zoo ntawm kev sib txuas lus thiab kev ntseeg siab nrog cov neeg siv khoom, kom cov neeg siv khoom muaj kev nyab xeeb los sab laj nws txog cov teeb meem ntawm cov khoom thiab cov kev pabcuam.Nws ib txwm nkag siab txog cov kev xav tau thiab cov kev xav tau ntawm cov neeg siv khoom, thiab dhau los ntawm kev tsim kho thiab kev pabcuam tus kheej, cov neeg siv khoom txaus siab tau ua tiav."Niam Zhao yog peb tus khub. Nws paub peb cov khoom thiab peb cov lag luam zoo heev, thiab peb ntseeg nws cov lus qhia."Ntau cov neeg siv khoom tawm tswv yim.
Cov pa roj carbon steel yog ib lub tiaj, nyias daim hlau ua los ntawm kev sib xyaw ntawm hlau thiab carbon.Cov ntsiab lus ntawm cov pa roj carbon steel yog li ntawm 0.05% mus rau 2.1% los ntawm qhov hnyav, nrog cov pa roj carbon ntau dua ua rau cov hlau hnyav dua thiab muaj zog dua.Cov ntawv carbon steel feem ntau yog siv rau hauv kev tsim khoom, kev tsim kho, thiab kev siv hauv kev lag luam vim nws cov kav ntev, ntau yam, thiab pheej yig.Nws tuaj yeem tsim tau yooj yim, welded, thiab txiav rau qhov loj me, ua rau nws yog qhov kev xaiv nrov rau ntau hom kev ua haujlwm.Tsis tas li ntawd, nws tuaj yeem raug kho los yog ua tiav kom tau raws li cov kev xav tau tshwj xeeb.
Cov pa roj carbon steel phaj yog tuab thiab muaj zog dua li cov pa roj carbon steel, thiab lawv feem ntau yog siv rau hauv kev tsim thiab kev siv, nrog rau kev tsim cov tshuab hnyav thiab khoom siv.Cov pa roj carbon steel phaj muaj cov ntsiab lus ntawm 0.18% mus rau 2.1% los ntawm qhov hnyav, thiab lawv tuaj yeem ua alloyed nrog lwm cov hlau los txhim kho lawv cov khoom thiab ua rau lawv haum rau cov kev siv tshwj xeeb.Qee cov ntsiab lus alloying muaj xws li manganese, silicon, tooj liab, nickel, thiab chromium.
Cov pa roj carbon steel tuaj yeem ua tau kub-kuav los yog txias-dov, thiab lawv feem ntau muaj nyob rau hauv ntau qib thiab tuab.Lub hardness thiab lub zog ntawm cov pa roj carbon steel phaj nyob ntawm nws qib thiab tshuaj muaj pes tsawg leeg.Cov pa roj carbon tsawg yog softer thiab ductile ntau dua, thaum cov pa roj carbon steel phaj siab dua thiab muaj zog dua, ua rau lawv haum rau kev siv hnyav.
Qee qhov kev siv cov pa roj carbon steel phaj muaj xws li cov tsheb thauj khoom, txuas hniav, cov tsev, cov kav dej, cov tank cia, thiab cov hlab ntsha siab.Cov pa roj carbon steel kuj tseem siv rau hauv kev tsim khoom ntawm cov khoom siv sab nrauv drilling, cov khoom siv ua liaj ua teb, thiab kev tsim kho tshuab.Lawv yog cov kev xaiv nrov rau cov ntawv thov uas xav tau lub zog, toughness, thiab durability.
Yog tias koj xav yuav steel ntau lawm tsis ntev los no, thov koj xav tiv tauj peb, (tuaj yeem ua raws cai) peb kuj tam sim no muaj qee cov khoom xa tuaj tam sim.
