Hlau Yeeb Nkab, yog ua los ntawm cam khwb cia hlau raws li cov khoom siv hauv paus. Ua ntej pouring, magnesium los yog tsawg lub ntiaj teb magnesium thiab lwm yam spheroidizing neeg sawv cev yog ntxiv rau molten hlau rau spheroidize lub graphite, thiab ces cov yeeb nkab yog tsim los ntawm ib tug series ntawm complex txheej txheem. Qhov tshwj xeeb ntawm cov hlau nplaum yog tias feem ntau lossis tag nrho cov precipitated graphite yog nyob rau hauv daim ntawv kheej kheej, thiab cov yam ntxwv ntawm cov qauv no zoo heev txhim kho kev ua haujlwm ntawm cov khoom. Tom qab annealing, lub metallographic qauv ntawmDub Hlau Tubeyog ferrite ntxiv rau ib qho me me ntawm pearlite, thiab cov khoom siv kho tshuab zoo. cov
Keeb kwm kev loj hlob ntawmHlau Tubeyog tag nrho ntawm innovation thiab breakthroughs. Nyob rau hauv lub lig 1980s thiab thaum ntxov 1990s, ntsib lub blockade ntawm txawv teb chaws centrifugal ductile hlau yeeb nkab ntau lawm technology thiab hnyav patent tso cai tej yam kev mob, lub 2672nd Hoobkas ntawm Tuam Tshoj tus Liberation Army (tus thawj coj ntawm Xinxing Casting Pipe) bravely coj nyob rau hauv lub luag hauj lwm ntawm ywj siab tshawb fawb thiab kev loj hlob. Xyoo 1993, thawj centrifugal ductile hlau yeeb nkab nyob rau hauv Suav teb tau ua tiav cov kab ntau lawm, kos npe tias kuv lub teb chaws tau ua tiav cov leap ntawm kos hauv daim teb no, thiab nws siv sijhawm yim xyoo los ua kom tiav 40-xyoo txoj kev loj hlob ntawm Western lub teb chaws. Niaj hnub no, Xinxing Casting Pipe tau tsim los rau hauv lub ntiaj teb loj tshaj plaws thiab muaj zog tshaj plaws centrifugal ductile hlau yeeb nkab chaw tsim tshuaj paus, thiab kuj tau koom nrog hauv kev tsim cov qauv ntawm lub ntiaj teb cam khwb cia yeeb nkab qauv, txuas ntxiv txhim kho kev lag luam ntawm cov kav hlau yeeb nkab.
Ductile Iron Pipes muaj ntau yam kev ua tau zoo
1. Siab zog thiab zoo toughness: Cov kav dej hlau muaj lub zog siab, thiab lawv lub zog yog qhov zoo dua qub piv rau cov kav hlau cam khwb cia. Vim tias graphite tau muab faib rau hauv cov duab kheej kheej, qhov sib cais ntawm cov matrix raug txo qis, ua rau cov yeeb nkab tsis tshua muaj kev tawg thaum raug siab dua thiab cuam tshuam. Nyob rau tib lub sijhawm, nws kuj muaj qhov toughness zoo, nrog rau qhov elongation feem ntau ntau dua 10%, thiab tuaj yeem hloov mus rau hauv av, av txav thiab lwm yam xwm txheej rau qee yam. Nws tsis yooj yim rau kev puas tsuaj los ntawm deformation, uas txhim kho kev ntseeg siab ntawm cov yeeb nkab network ua haujlwm ..
2. Muaj zog corrosion kuj: Los ntawm ntau yam txheej txheem los tiv thaiv corrosion, xws li asphalt xim txheej, cement mortar hauv ob sab phlu, epoxy coal tar txheej, epoxy ceramic hauv ob sab phlu, aluminate cement txheej, sulfate cement txheej thiab polyurethane txheej, ductile hlau kav tuaj yeem tiv taus corrosion los ntawm cov xov xwm sib txawv. Txawm hais tias nws yog siv los thauj cov pa roj, dej kais dej, lossis rau cov dej phwj tuaj, nws tuaj yeem tswj xyuas kev ua haujlwm ruaj khov nyob rau hauv ntau qhov chaw ib puag ncig, txuas ntxiv lub neej kev pab cuam ntawm cov kav dej, thiab txo cov nqi tu. cov
3. Zoo sealing: Cov yeeb nkab lub qhov ncauj txais qhov hloov pauv hloov tau, uas tuaj yeem hloov pauv mus rau qhov hloov pauv thiab deformation nyob rau hauv qee qhov ntau, tsim cov nyhuv sealing zoo ntawm cov yeeb nkab txuas, thiab tiv thaiv cov kua dej tawm. Nyob rau tib lub sijhawm, cov txheej txheem kev tsim khoom siab ntawm cov yeeb nkab nws tus kheej ua kom qhov sib txuam ntawm lub qhov (socket), ntxiv txhim kho kev sib khi, thiab ua kom muaj kev nyab xeeb ntawm cov kav dej. cov
4. Yooj yim installation: Piv nrog rau lwm cov kav dej, qhov hnyav ntawm cov kav hlau kav yog qhov nruab nrab, thiab cov txheej txheem kev teeb tsa kuj yooj yim. Nws qhov hloov pauv hloov pauv tau yooj yim rau cov neeg ua haujlwm tsim kho kom ua tiav kev sib txuas ua haujlwm, txo lub sijhawm teeb tsa thiab kev siv zog ua haujlwm. Ntawm qhov chaw tsim kho, kev teeb tsa cov kav dej tuaj yeem ua tiav sai sai yam tsis muaj cov cuab yeej siv thiab cov kws tshaj lij, uas ua rau lub voj voog ua haujlwm luv luv thiab txhim kho kev tsim kho. cov
5. Zoo Antifreeze Performance: Hauv thaj chaw txias, kev ua haujlwm ntawm cov kav dej yog qhov tseem ceeb heev. Cov kav hlau kav hlau muaj qee qhov kev tiv thaiv kab mob. Tsuav nws tsis yog ib puag ncig hnyav heev, yuav tsis muaj qhov khov thiab tawg. Qhov no ua rau nws siv dav hauv dej, cua sov thiab lwm cov kav dej hauv cov cheeb tsam txias sab qaum teb, muab cov kev pabcuam txhim khu kev qha rau cov neeg nyob hauv thiab cov lag luam. cov
Cov kav dej ductile hlautau dhau los ua ib qho tseem ceeb thiab tseem ceeb cov khoom siv yeeb nkab hauv kev tsim kho vaj tse niaj hnub nrog lawv cov yam ntxwv ua tau zoo. Los ntawm cov dej hauv nroog thiab cov dej xa mus rau cov roj xa mus, los ntawm kev tsim khoom lag luam mus rau kev txuag dej, cov kav dej hlau ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam thiab tau ua ib qho tseem ceeb hauv kev ua kom tib neeg lub neej zoo thiab txhawb kev txhim kho kev lag luam. Nrog rau kev nce qib txuas ntxiv thiab kev tsim kho tshiab ntawm cov thev naus laus zis, kev ua haujlwm ntawm cov kav hlau kav hlau yuav txuas ntxiv txhim kho, thiab cov peev txheej ntawm daim ntawv thov yuav nthuav dav ntxiv. Lawv tseem yuav ci ntsa iab hauv kev tsim kho vaj tse yav tom ntej. cov
