Yuav ua li cas pub cov channel ntawm malleable steel yeeb nkab fittings thiab steel castings tsim?
May 17, 2023
Nrog rau txoj kev loj hlob sai ntawm kuv lub teb chaws txoj kev lag luam, qhov kev thov rau malleable cam khwb cia hlau pipeline connectors (feem ntau hu ua malleable steel yeeb nkab fittings) rau dej, roj thiab roj circuits yog nce nyob rau hauv ib hnub, thiab cov kev cai rau nws zoo kuj tau txais ntau dua thiab. siab dua.
Kev siv ntawm malleable steel yeeb nkab fittings rau qhov loj ntawm castings. Tsis zoo li cov hlau nplaum casting, castings tsim los ntawm qhov tsis zoo siab cov khoom casting yog txwv los ntawm qhov loj ntawm qhov sib nqus ncej sib nrug. Ntev npaum li qhov loj ntawm tus ncej hlau nplaum yog tsau, qhov loj ntawm lub thawv xuab zeb kuj tau txiav txim siab. Nws yog yuav luag tsis yooj yim sua rau cam khwb cia-qhov loj me castings, thiab nws yog feem ntau tsuas yog haum rau pouring me me pieces ntawm ib puas thiab kaum kilograms. Tsis zoo siab cov khoom indium casting yog ntau ntxiv rau qhov loj ntawm castings. Cov thawv xuab zeb ntawm ntau qhov sib txawv tuaj yeem muab tso rau ntawm tib lub rooj vibrating, yog li castings ntawm ntau qhov ntau thiab tsawg tuaj yeem tsim tau yooj yim heev.
Txawm li cas los xij, vim qhov tsis tshua muaj zog ntawm cov qauv yas ua npuas ncauj, thiab qhov tseeb tias cov khoom ntim tsis tuaj yeem tsis sib xws thaum lub sijhawm ua haujlwm, cov qauv yooj yim deformed, uas ua rau muaj qee yam teeb meem rau casting loj, nqaim thiab nyias. Yog li ntawd, xav txog qhov yooj yim ntawm kev lag luam thiab cov thev naus laus zis uas twb muaj lawm, qhov tsis zoo siab compact casting yog tsim rau castings nrog castings hauv qab 2t (tshwj xeeb tshaj yog 500kg) thiab nrog phab ntsa thickness ntau dua 4 hli.
Spinning ntawm malleable steel yeeb nkab fittings feem ntau yog siv los ua cov pa roj carbon steel nrog lub thickness tsawg dua 1. Rau qhov thicker, rhuab spinning yuav tsum tau siv. Tam sim no qhia txog cov txheej txheem spinning ntawm ob peb yam.
Muaj ob hom taub hau spinning, ntsug thiab kab rov tav. Cov taub hau loj feem ntau yog spun rau ntawm lub tshuab ntsug spinning. Feem ntau ntawm lub tshuab spinning no yog siv ua ke nrog cov xovxwm zoo tib yam. Tom qab lub dome yog pre-pressed los ntawm cov xovxwm zoo tib yam, lub flanging yog ces spun ntawm lub tshuab spinning. Domes thiab flanges tseem tuaj yeem nias ncaj qha rau ntawm lub tshuab spinning.
Cov cua sov ntawm lub fillet ib feem ntawm lub taub hau yog nqa tawm nyob rau hauv lub cua sov rauv, thiab cov nplaim hluav taws kub yog ignited rau cov cua sov hauv zos. Txij li thaum lub sealing lub taub hau tig tsis tu ncua nyob ib ncig ntawm lub ntsiab ncej, lub cua sov ntawm lub sealing lub taub hau nyob rau hauv lub circumferential kev taw qhia yog uniform. Spinning nyob ntawm kev ua haujlwm ntawm cov menyuam txheej sab nraud, txoj haujlwm ntawm cov menyuam sab nraud yog hloov kho los ntawm kab rov tav thiab ntsug axis los kho txoj haujlwm ntawm cov menyuam sab nraud hauv kab rov tav thiab ntsug, thiab cov menyuam txheej sab nraud kuj tuaj yeem hloov pauv. dawb do, yog li cov menyuam sab nrauv yog ib txwm nyob rau hauv cov txheej txheem spinning tuaj yeem ua rau kev sib cuag zoo nrog lub taub hau.
Cov duab ntawm lub taub hau spinning yog qhov tseeb, yeej tsis muaj ovality thiab wrinkles, thiab qhov loj me me. Kev ua haujlwm xws li ntug trimming thiab beveling tuaj yeem ua rau ntawm lub tshuab spinning.
