Round steel mas suav nrog round steel stainless hlau thiab round steel carbon steel:
1. Raws li cov txheej txheem, round steel yog muab faib ua peb hom: kub dov, forging thiab txias daim duab.Cov specifications ntawm kub dov puag ncig tuav yog 5.5-250 hli, ntawm cov uas, cov me me puag ncig tuav ntawm 5.5-25 hli feem ntau muab nyob rau hauv bundles ntawm ncaj strips, uas yog feem ntau siv raws li steel tuav, bolts thiab ntau yam khoom siv;puag ncig tuav loj dua 25 hli yog feem ntau Rau kev tsim khoom ntawm cov khoom siv kho tshuab, raj blanks rau seamless steel raj, thiab lwm yam.
2. Raws li tshuaj lom neeg muaj pes tsawg leeg, round steel carbon steel (uas yog, nyob rau hauv cov nqe lus ntawm cov ntsiab lus carbon) yuav muab faib ua tsawg carbon steel, nruab nrab carbon steel thiab siab carbon steel.
3. Raws li cov hlau zoo, cov hlau puag ncig tuaj yeem muab faib ua cov pa roj carbon zoo tib yam thiab cov pa roj carbon zoo.
4. Raws li lub hom phiaj, cov hlau puag ncig tuaj yeem muab faib ua cov qauv hlau thiab cov cuab yeej carbon steel.
Lub round steel yog cais raws li cov txheej txheem ntau lawm: nws muab faib ua peb hom: kub dov, forging thiab txias kos duab.
Kub dov puag ncig steel yog txoj kev ua haujlwm siab uas cov hlau billet tau dhau los ntawm ib khub ntawm cov rotating yob (ntau yam duab), thiab cov khoom seem raug txo thiab qhov ntev yog nce vim qhov compression tsim thiab dov ntawm cov yob.Qhov no yog txoj kev siv ntau tshaj plaws rau kev tsim steel.Nws yog tsuas yog siv los tsim cov profiles, daim hlau thiab cov kav dej.
Forged round steel: yog hais txog cov hlau puag ncig uas tuaj yeem tsim los ntawm forging.Feem ntau, qhov zoo ntawm cov hlau puag ncig uas tsim los ntawm kev pub dawb forging dov txoj kev yog zoo dua nyob rau hauv cov xwm txheej ntawm tib lub deformation piv, vim forging kom ua tiav tib lub deformation tus nqi ntawm dov yuav tsum tau rov forging rau elongate (forging yog dawb deformation thiab dov nws. yog constrained deformation), yog li tib lub billet ua tib yam tiav round steel forging yog sib npaug rau qhov nce ntawm deformation piv ntawm dov los ntawm ntau tshaj 50%.Tsis tas li ntawd, feem ntau, forging yog tag nrho cov deformation ntawm cov hlau los ntawm qhov chaw mus rau sab hauv thiab dov nto yog deformed ua ntej, yog li Cov qauv sab hauv, kev sib cais degree, hlau ntws kab, thiab lwm yam. yog txawv kiag li, thiab qhov zoo ntawm forged puag ncig tuav yog feem ntau zoo dua li ntawm dov puag ncig tuav.Yog li ntawd, cov khoom tseem ceeb xws li crane nuv taub hau yuav tsum yog forged qhov chaw.
Cold-drawn round steel: tseem hu ua txias-drawn round steel, txias-draw caij steel, txias-draw round steel, thiab du round steel, nws yog ib hom txias-draw seem steel.Txawm hais tias nws yog txias-draw round steel lossis round steel, nws cov duab yog puag ncig, tab sis qhov saum npoo ntawm txias-draw round steel yog du heev, nws qhov tseeb qhov tseeb yog siab, thiab nws cov khoom siv kho tshuab siab.Vim nws qhov siab qhov tseeb, nws tuaj yeem siv ncaj qha yam tsis muaj kev ua haujlwm.
Round steel muaj dav daim ntawv thov kev cia siab thiab yog dav siv nyob rau hauv kho vajtse, kev tsim kho, tsheb, shipbuilding, petrochemicals, machinery, tshuaj, zaub mov, hluav taws xob, lub zog, aerospace, thiab lwm yam, lub tsev kho kom zoo nkauj.Kev ua haujlwm ntau tshaj plaws ntawm cov khoom siv tshuab zoo tib yam, cov pas nrig steel, CD rods, bolts, ceev.
| Ntim | Txheem seaworthy export packing, lwm hom ntim tuaj yeem ua raws li txhua qhov kev xav tau. |
| Shipping ntim | Bundled nrog ruaj steel straps, yooj yim rau thauj thiab unloading. |
