Cov khoom siv raw ntawm tus ntsia thawv yog ib puag ncig steel, tom qab kos duab, txoj kab uas hla ntawm tus ntsia thawv yog rub tawm, kos duab tshuab.
Tom qab kos lub dia ntawm cov hlau los ua tus ntsia thawv tsim, ces tuaj yeem tsim cov ntsia hlau los ntawm cov ntsia hlau ua tshuab raws li hauv qab no:
Raws li peb cov kev paub dhau los peb xav kom siv peb cov ntsia hlau ceev ceev ua tshuab raws li peb tau pom hauv peb lub vev xaib.
Tom qab ntawd tus Tsov tus tw thiab qhov kawg ntawm tus ntsia thawv yog ua,tom qab polishing, cov khoom siv tes yog qhov tiav. Yog tias qhov saum npoo ntawm tus ntsia thawv xav tau rau electroplating lossis cov plaub hau dub, koj tuaj yeem ntxiv cov txheej txheem no.
Cov txheej txheem ntau lawm ntawm cov rau tes yog tsuas yog cov txheej txheem xws li txhuam, txias, polishing thiab lwm yam txheej txheem, thiab cov txheej txheem ntawm cov rau tes yog qhov yooj yim.
Hauv engineering, carpentry thiab architecture, cov ntsia hlau xa mus rau cov hlau tawv (feem ntau yog hlau), uas yog siv los ua cov ntoo ruaj khov thiab lwm yam khoom. Lub rauj ntsia hlau ntsia hlau rau hauv cov khoom, thiab tseem muaj ib rab phom ntsia hlau, thiab cov ntsia hlau ntsia hlau tshwm. Yog li ntawd, cov ntsia hlau tuaj yeem ruaj khov, thiab nws dai ntawm nws los ntawm nws tus kheej deformation, thiab cia siab rau kev sib txhuam.
Cov ntsia hlau muaj cov duab sib txawv vim siv ntau yam. Cov ntsia hlau feem ntau hu ua "cov ntsia hlau". Tsis tas li ntawd, cov npe ntsia hlau feem ntau suav nrog cov koob taub hau loj, ntsia hlau lossis txiav. Cov ntsia hlau tau siv dav, muaj ntau yam kev siv, rivets siv dav dav dav hlau thauj khoom kim dua, thiab cov ntsia hlau zoo tib yam yog pheej yig dua.
Muaj ntau yam ntawm cov ntsia hlau raws li kev siv sib txawv, xws li:
Twist rau tes, uas lub cev zoo li twist, lub taub hau yog puag ncig-puab, tus ntoo khaub lig los yog ib lub taub hau, thiab hauv qab yog hauv qab. Tus ntsia thawv quab yuam tshwj xeeb yog muaj zog. Nws yog haum rau qee qhov chaw uas yuav tsum tau ntsia hlau heev, xws li drawers, ntoo qab nthab bar, thiab lwm yam. Cov kev qhia tshwj xeeb muaj ntau yam tshwj xeeb ntawm 50 ~ 85mm.
