Qhov Precision ntawm Seamless Pipe Manufacturing
Seamless steel yeeb nkab yog tus qauv rau siab -siab ntim. Nrog tsis muaj longitudinal sib koom ua ke, nws ua kom 360 degrees ntawm lub zog sib xws. Kev tsim khoom yog qhov siab - cov txheej txheem hluav taws xob uas muaj cov cuab yeej tshwj xeeb tsim los ua haujlwm ntawm qhov kub siab tshaj ntawm cov hlau qhov chaw recrystallization.
1. Txheej Txheem Rotary Piercing (Mannesmann).
Lub hom phiaj ntawm seamless ntau lawm yogRotary Piercing. Ib tug kub billet yog thawb ntawm tapered yob rotating nyob rau hauv tib txoj kev. Compressive rog qhib qhov khoob, thiab lub conical mandrel raug yuam los ntawm kev tsim lub plhaub hollow ntxhib. Txoj kev "Zero-Seam" no ua kom muaj kev sib haum xeeb.
2. Elongation thiab Rolling
Lub plhaub dhau los ntawm cov theem zeb (plug zeb lossis mandrel zeb) qhov twg phab ntsa thickness txo thiab ntev nce. Qhov no refines qhov tseeb qhov tseeb thiab nto tiav.
3. Qhov loj me thiab txias
Qhov kawg qhov ntev yog ua tiav hauv aSizing Mill. Cov yeeb nkab dhau los ntawm cov yob kom ncav cuag lub hom phiaj OD thiab ncig, tom qab ntawd txias rau hauv kev tswj xyuas kom tsis txhob muaj kev sib tsoo.
Kev sib piv zoo
| Theem | Lub hom phiaj technical | Kev cuam tshuam zoo |
|---|---|---|
| Piercing | Ncauj creation tsis muaj tearing | Internal kev ncaj ncees |
| Rolling | Phab ntsa thickness uniformity | Concentricity |
| Qhov loj me | OD kawg thiab ncaj | Haum- nyob rau hauv qhov chaw vuam |
FAQs
Puas yog seamless muaj zog dua welded?
Yog lawm, tshem tawm qhov kev sib koom ua ke ntawm kev sib koom ua ke tso cai rau kev ntsuas siab dua.
'Eccentricity' yog dab tsi?
Variation ntawm phab ntsa thickness nyob ib ncig ntawm lub circumference. Mills siv laser -gauging los txo qhov no.
Qhov ntau thiab tsawg?
Seamless feem ntau txwv rau txoj kab uas hla hauv qab 28 ntiv tes.
Qhov txawv ntawm HR thiab CD?
HR yog siab - cua sov rau kev siv dav dav; CD ntxiv ib chav -temp kauj ruam rau ultra- nruj tolerances.
Dab tsi yog 'Hollow Billet'?
Ib qho ua ntej-drilled billet siv nyob rau hauv extrusion los coj tus tho mandrel.
