Lub hauv paus rau phau ntawv
Hauv cov av loj hauv kev tsim hluav taws xob txhawb nqa hluav taws xob ntau lawm, kev thauj khoom, thiab lub zog ntawm cov tshuab nias tsis yog {sib ceg. Seamless steel yeeb nkab pabcuam raws li kev siv hluav taws xob tseem ceeb rau cov ntawv thov uas xav tau no thiab feem ntau muaj kev phom sij hauv dej nyob rau hauv siab kub thiab siab. Nws cov txiaj ntsig zoo nyob rau hauv nws cov kev xav ua yeeb yam zoo; Qhov qhaj ntawv ntev ntawm Weld Team tshem tawm qhov muaj zog ntawm qaug zog, muab kev ntxhov siab zoo dua qub, thiab corrosive nres thoob plaws hauv phab ntsa.
Qhov kev tsim kho monolithic yog qhov tseem ceeb rau cov ntawv thov uas tsis muaj peev xwm nqa cov roj, cov roj av siab, thiab cov khoom siv hauv cov chaw tsim hluav taws xob nuclear. Kev tsim kev taug kev ntawm seamless yeeb yog ib qho kev hloov metallurgical, xav tau precision engineering thiab nruj kev tswj kom ua tiav txoj kev xav tau.
Dab tsi yog seamless steel yeeb nkab
Seamless steel yeeb nkab yog txawv los ntawm nws cov keeb kwm kev tsim khoom: nws yog tsim los ntawm ib qho, khoom cylindrical billet ntawm hlau tsis muaj kev siv vuam ntev. Cov yeeb nkab tau txais nws cov duab thiab qhov loj me ntawm cov txheej txheem kev ua haujlwm, tho, elongating, thiab txo cov khoom ntim tau thaum cov hlau yog kub lossis txias. Qhov kev sib txawv no muaj cov yeeb nkab welded, uas yog tsim los ntawm dov tiaj tus kab txaij lossis phaj rau hauv cov npoo nrog lub npoo weld.
Qhov tsis muaj ntawm Weld Seam hauv seamless yeeb nkab ua rau kev nruam cov qauv, homogeneous grain accove ncig ncig cov yeeb nkab. Cov qauv tsim qauv no txhais ua cov khoom siv kho tshuab, tshwj xeeb tshaj yog tawg ntho kom tawg tau lub zog thiab nkees ua kom tsis kam thauj khoom. Tsis tas li ntawd, cov phab ntsa nruj heev thiab muab cov ntaub ntawv sib txawv hauv cov ntawv thov corrosion thiab muab cov kev tsis haum xeeb cuam tshuam nrog weld affores.
Cov txheej txheem tsim khoom ntawm seamless yeeb nkab
Kev tsim ntawm cov yeeb nkab steelless yog cov txheej txheem sib txawv ntawm cov txheej txheem thermiechanical, feem ntau nyob ib ncig ntawm cov malcing zeb thiab txuas ntxiv elongation / recitating. Nws pib nrog nruj screen cylindricalylalrical cylindrical me me cylindrically cylindrically cam khwb cia thiab tus conduction los xyuas kom meej meej lub suab thiab qhov tseeb raug. Lub billet yog rhuab tsis zoo nyob rau hauv lub teb hearth hearth lossis taug kev ci kom sov rau lub zog kub, feem ntau zoo tshaj 1200℃(rendering tus qauv yas.
Tom qab ntawv kub tau noj rau hauv lub zeb teb av, lub plawv ntawm seamless ntau lawm. Ntawm no, lub billet yog gripped los ntawm conical rolls teev ntawm lub kaum sab xis ntawm kev sib hloov thiab tsav pem hauv ntej ntawm ib qho chaw nyob, taw qhia mandrel. Qhov kev ua no induces muaj siab ntau thiab ntxim nyiam kev nyuaj siab, tho qhov nruab nrab ntawm lub pob tawb kom tsim lub hnab nyiaj, hu ua "Bloom" lossis "Hollow." Lub hau no tau hloov pauv tam sim ntawd mus rau elongating mills, xws li ib lub ntsaws, manrel zeb, lossis lab.
Cov mills siv kev sib txuas ua ke ntawm yob thiab cov cuab yeej sab hauv (ntsaws cov cuab yeej hauv av, kom txo qhov ntev, thiab txhim kho qhov tsis zoo. Tom ntej sizing lossis txo cov mills nplua -}}}}}}}} txoj hlua uas hla sab nraud thiab phab ntsa thickness rau qhov kawg. Txhawm rau txhim kho qhov qis qis, cov khoom ua kom tiav, thiab cov tshuaj tsuag kub, qhov twg nws rub lossis dov thiab hla ntawm cov lus kub. Thaum kawg, cov yeeb nkab undergoes strooforous tshav kub kho kom zoo rau cov khoom siv hlau thiab yuav tsum tau ua raws li cov tsis muaj kev sim siab.
Seamless vs. Welded Yeeb Nkab
Qhov kev xaiv ntawm seamless thiab welded yeeb nkab hinges ntawm daim ntawv thov kev kawm tshwj xeeb, tshwj xeeb yog kev ntseeg siab, thiab corrosion tsis kam. Thaum cov kav dej welded, tsim los ntawm cov txheej txheem xws li ERW, LSAW, muaj qhov tsim nyog them rau ntau qis {1} Kev muaj qhov kev sib tw weld ntev.
Qhov no yuav sawv cev rau thaj chaw sib txawv. Txawm tias muaj kev nce qib hauv vuam Technology, lub weld cua sov {}}} kev sib txawv ntawm cov qauv sib txawv, thiab muaj kev txhawj xeeb piv rau niam txiv hlau. Cov kev hloov pauv no tuaj yeem ua raws li cov chaw rau kev ua kiav txhab, lossis loj hlob, tshwj xeeb yog thaum muaj kev thauj mus los ntau, lossis cov chaw muaj kev sib cav.
Seamless cov yeeb nkab, devoid ntawm no longitudinal welontinuity, muab cov qauv sib dhos thoob plaws hauv nws txoj kev ncig. Qhov kev sib txuam no tau muab Inherfority muab lub zog siab dua {}} qhov kev ntxhov siab, thiab kev cuam tshuam zoo tshaj plaws hauv kev ua kom muaj zog thiab sab nraud. Thiaj li, seamless yeeb nkab yog qhov kev xaiv lossis xaiv tau rau cov kev pabcuam pabcuam feem ntau.
Seamless steel yeeb nkab ntawv thov
