Ua ntej peb pib piav qhia txog steel hlau, cia peb nkag siab tias nws yog dab tsi. Peb txhua tus tau pom cov hlau thiab paub tias nws cov xim tuaj yeem sib txawv kiag li - los ntawm ci ntsa iab mus rau lub teeb silvery. Ib tug hlau yog ib tug ntev hlau hlua los yog xov ntawm ntau yam thicknesses. Raws li cov hlau los ntawm cov khoom siv no, nws tuaj yeem yog tooj liab, txhuas, hlau, titanium, zinc, thiab lawv cov alloys. Cov hlau feem ntau yog puag ncig, txawm hais tias nws tuaj yeem yog square, nrog rau trapezoidal, tab sis ntau tsawg dua.
Nyob ntawm cov xaim
Vim nws lub cev zoo thiab kev ua haujlwm zoo, ib qho ntawm cov khoom siv no feem ntau yog hlau hlau. Nws tuaj yeem ua tau ntau yam sib txawv. Ib tug ntawm lawv yog daim duab txias. Lub ntsiab lus ntawm cov thev naus laus zis no nyob hauv qhov tseeb tias lub tshuab ua haujlwm hlau preheated yog rub (raug) los ntawm lub qhov ntawm lub taub me me. Hlau hlau yog ib hom dov profiles uas txawv nyob rau hauv cov duab. Nyob ntawm lub hom phiaj, nws tuaj yeem ua vuam (GOST 2246-70), springy (GOST 9389-75), txhawb nqa (raws licov khoom siv ntxiv hauv cov qauv ua vaj tse), thiab lwm yam.
Ntau yam steel hlau
Tam sim no, muaj peb yam tseem ceeb ntawm steel hlau:
- qis carbon steel hlau
- Txhob xaim
- High alloyed hlau
Cov ntau yam nrov tshaj plaws yog cov hlau tsis muaj cov pa roj carbon tsawg, uas cov ntsiab lus carbon tsawg dua li lwm hom hlau. Piv txwv li, ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov hlau no yog qhov me me rau qhov kub siab, piv txwv li thaum vuam. Tsis tas li ntawd, peb tuaj yeem sau npe rau qib siab ntawm corrosion kuj, yooj thiab toughness. Feem ntau, steel hlau los ntawm cov hlau me me yog tsim nrog ib txoj kab uas hla ntawm 0.2 txog 8.0 hli. Cov khoom no yog tsim los ntawm txoj kev rov ua kom txias txias.
Txoj kev sib txawv ntawm cov hlau
Los ntawm lub hom phiaj, raws li tau hais los saum toj no, steel hlau tuaj yeem faib raws li hauv qab no.
- Knitting hlau. Hom dov hlau no feem ntau yog siv rau kev sib txuas ntawm ntau yam kev sib txuas los yog kev tsim cov ntsia hlau. Hom hlau no tseem hu ua "kev lag luam". Nws yog ib txwm ua los ntawm cov pa roj carbon tsawg, thiab raws li qhov xwm txheej ntawm cov txheej txheem sab nraud, nws tuaj yeem ua galvanized thiab tsis-galvanized.
- Qib hlau feem ntau yog siv raukev tsim cov khoom siv. Ib txwm ua los ntawm high carbon steel.
- Caij nplooj ntoos hlav hlau, raws li lub npe txhais tau tias, yog siv rau kev tsim ntau hom springs los ntawm tshwj xeeb txias winding. Tsis muaj txheej txheem hardening.
Yog tias peb xav txog cov khoom siv hlau hlau, cov qauv hauv qab no tuaj yeem muab tau: cov ntsia hlau, ntsia hlau, ntsia hlau, rivets, ntsia hlau, hlua, fittings, obstacles, laj kab.
