Raws li cov khoom siv hlau siv dav hauv kev lag luam, carbon steel profiles ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw vim lawv cov khoom siv zoo heev thiab tus nqi qis.Txawm li cas los xij, lawv cov kev siv tau cuam tshuam los ntawm ib puag ncig, suav nrog kub, av, corrosive media, thiab mechanical stress. Kab lus no yuav tshawb txog qhov siv tau thiab kev txwv ntawm carbon steel profiles raws li qhov sib txawv ib puag ncig.
Qhov kub thiab txias ib puag ncig
Hauv qhov chaw qhuav nrog chav sov (kwv yees li -20℃txog 60 degree), carbon steel profiles muaj kev ruaj khov thiab ua haujlwm ntev heev. Xws li ib puag ncig feem ntau pom muaj nyob rau hauv cov tsev nyob sab hauv tsev, kev txhawb nqa txhua yam, thiab cov khoom siv sib xyaw ua ke. Vim tsis muaj dej noo thiab corrosive media, carbon hlau tsis tshua muaj kev cuam tshuam rau oxidation lossis tshuaj tua kab mob. Nws lub zog siab thiab kev ua haujlwm zoo ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv thauj khoom. Tsis tas li ntawd, carbon steel profiles xav tau kev saib xyuas tsawg dua hauv qhov chaw qhuav thiab tswj cov khoom siv kho tshuab ruaj khov nyob rau lub sijhawm siv ntev.
Kub kub ib puag ncig
Kev siv tau ntawm carbon steel profiles nyob rau hauv siab - qhov kub thiab txias ib puag ncig (feem ntau tshaj 300 degree) yog me ntsis txwv. Raws li qhov kub thiab txias nce, carbon steel lub zog thiab hardness maj mam txo, thiab nkag mus- qeeb deformation nyob rau hauv kev ntxhov siab nyob rau hauv kev ruaj ntseg- tej zaum yuav tshwm sim. Txawm li cas los xij, nyob rau hauv qhov kub siab (piv txwv li, 100℃txog 300 degree), carbon hlau tseem tuaj yeem siv rau hauv cov ntawv thov xws li kev txhawb nqa boiler thiab cov yeeb nkab thermal, tab sis qhov cuam tshuam ntawm thermal expansion coefficient ntawm cov qauv kev ruaj ntseg yuav tsum raug txiav txim siab. Rau lub sijhawm ntev - raug rau qhov kub thiab txias, nws raug nquahu kom siv cov cua sov- cov hlau tiv taus lossis ntxiv cov txheej tiv thaiv kom ntev nws lub neej kev pab.
Tsawg- Ib puag ncig kub
Ntawm qhov kub thiab txias (piv txwv li, qis dua -20 degree), qhov toughness ntawm carbon steel profiles txo qis. Tshwj xeeb tshaj yog nyob rau hauv los yog qis dua cov ductile - nkig hloov pauv kub, cov khoom yuav ua nkig thiab nquag tawg nyob rau hauv kev cuam tshuam loads. Yog li ntawd, kev siv cov pa roj carbon steel hauv cov haujlwm polar, txias - thaj chaw cia tso tsheb hlau luam, lossis cov qauv hlau sab nraum zoov yuav tsum tau ua tib zoo soj ntsuam. Yog tias qis-kev siv kub tsis tuaj yeem zam tau, qis- carbon steel (xws li, Q235B) tuaj yeem raug xaiv lossis raug rau kev kho cua sov kom tsim nyog los txhim kho nws qhov kub thiab txias, thaum tseem ntxiv dag zog rau cov qauv tsim los tiv thaiv kev ua tsis tiav.
Corrosive Ib puag ncig
Cov pa roj carbon steel extrusion muaj qhov cuam tshuam rau xeb nyob rau hauv ib puag ncig nrog av noo, ntsev, los yog tshuaj corrosive media (xws li acids, alkalis, thiab ntsev tsuag). Lawv cov kev tiv thaiv corrosion yog qis dua li ntawm cov hlau tsis muaj steel lossis lwm yam alloys. Nyob rau hauv ib puag ncig corrosive heev, xws li cov ntug dej hiav txwv, cov nroj tsuag tshuaj, los yog cov chaw kho dej khib nyiab, cov pa roj carbon steel yuav ua rau lub neej luv luv tshwj tsis yog muaj kev tiv thaiv ntxiv. Cov kev tiv thaiv uas muaj xws li:
1.Coating tiv thaiv: Daim ntaub ntawv xws li epoxy zinc- nplua nuj primers thiab polyurethane topcoats zoo thaiv cov dej noo thiab oxygen.
2.Electroplating los yog kub-dip galvanizing: nto hlau coatings txhim khu corrosion kuj.
3.Txhim kho tsis tu ncua: Repainting lossis tiv thaiv- kev kho corrosion tuaj yeem ua rau lub neej ua haujlwm ntev.
Rau cov cheeb tsam uas muaj corrosion siab heev (xws li cov kua qaub los yog alkalis), carbon steel extrusion feem ntau tsis haum thiab corrosion-cov alloys resistant lossis tsis yog- cov khoom siv hlau yuav tsum tau siv los hloov.
Dynamic Loads thiab Mechanical Stress Environments
Nyob rau hauv ib puag ncig uas yuav tsum tau dynamic loads (xws li kev vibration, shocks, los yog cyclic kev nyuaj siab), kev qaug zog ntawm carbon steel extrusion yog ib qho tseem ceeb xav txog. Txawm hais tias nws lub zog siab, cov pa roj carbon steel tuaj yeem tsim kev qaug zog tawg hauv qhov kev ntxhov siab ntau zaus, thaum kawg ua rau kev ua haujlwm tsis zoo. Xws li ib puag ncig muaj nyob rau hauv choj bearings, mechanical transmission components, thiab rail transit infrastructure. Txhawm rau kom muaj kev nyab xeeb, kev pheej hmoo txo qis yog qhov tseem ceeb los ntawm kev tsim qauv tsim nyog (xws li tsis txhob muaj kev ntxhov siab), xaiv cov khoom siv (xws li xaiv cov qib carbon steel nrog cov tawv tawv dua), thiab kev sim tsis tu ncua.
Xaus
Cov pa roj carbon steel profiles yog tsim rau ntau qhov chaw ib puag ncig, tab sis lawv cov khoom siv kho tshuab, kev tiv thaiv corrosion, thiab kev lag luam kev lag luam yuav tsum raug txiav txim siab raws li cov xwm txheej sib txawv. Hauv qhov chaw qhuav nrog qhov kub thiab txias, cov pa roj carbon steel yog cov khoom siv tau zoo thiab kev lag luam. Txawm li cas los xij, nyob rau hauv ib puag ncig uas muaj qhov kub siab lossis qis qis, corrosive tej yam kev mob, los yog dynamic loads, kev tiv thaiv los yog lwm yam ntaub ntawv yog tsim nyog los optimize nws daim ntawv thov. Kev soj ntsuam zoo ib puag ncig thiab ua raws li cov kev ntsuas tsim nyog tuaj yeem ua kom muaj txiaj ntsig zoo ntawm carbon steel profiles thiab xyuas kom lawv muaj kev ntseeg siab thiab kav ntev hauv ntau yam haujlwm.
