Siv thiab cov lus qhia siv cov casting electrodes
Siv cov cam hlau electrodes
Cam khwb cia hlau yog ib qho Fe-C alloy nrog ib pawg feem ntawm cov pob ntau dua 2.14%. Qhov tseeb, muaj hlau nrum feem ntau yog ntau lub caij raws li Fe-C-Si. Cov hlau cam khib nyiab feem ntau yog muab cais raws li cov qauv ntawm cov pa hauv cov cam khwb cia hlau, thiab feem ntau yuav muab cais ua dawb dawb cam hlau, grey cam khwb cia hlau, hlau luam, cov hlau cam khwb cia hlau thiab cov nplaum hlau. Vim muaj cov pa roj carbon tsawg, uneven microstructure, tsis tshua yas thiab pluag weldability ntawm cam khwb cia hlau, nws yog ib qho yooj yim los tsim cov kev xws li lub qhov ncauj dawb, cov kab nrib pleev thiab qhov pores thaum lub vuam txheej txheem. Cov xim tshwj xeeb yuav tsum tau them rau cov txheej txheem welding thiab xaiv cov khoom siv vuam thaum lub vuam siv. Rau cov electrode arc vuam, muaj tam sim no ntau tshaj 20 hom welding rods muaj nyob rau hauv Suav teb, uas yuav muab faib ua ob pawg, ib qho yog homogenous weld hom, uas yog, qhov cam khwb cia hlau; lwm qhov yog qhov sib txawv ntawm qhov sib xyaw. Ntshiab Ni (Fe (nickel hlau 408), Ni-Cu (nickel tooj liab 508), Ni-Fe-Cu, Fe- Cu thiab cov zoo li no. Thaum xaiv vuam cov hlua, nws tuaj yeem raug xaiv raws li ntau yam khoom siv hlau cam, sib txawv tej yam yuav tsum ua, cov kev pabcuam txawv txawv thiab qhov tseem ceeb, ntau yam ntxwv ntawm tus qauv, thiab muaj rigidity.
cov lus qhia siv cov cast iron electrodes
Cam khwb cia hlau yog hlau-carbon alloy uas muaj ntau tshaj 2% cov pa roj carbon. Tam sim no, ntau tshaj 10 hom castings steel welding rods yuav muab tau nyob rau hauv Suav teb, uas yuav xaiv tau raws li nyias cov ntaub ntawv hlau, nyias txiav ua raws thiab qhov tseem ceeb ntawm kev kho cov vuam siv tshuaj.
Cam khwb cia hlau yog ib qho khoom siv nrog kev txom nyem vim tias nws cov ntsiab lus siab, cov qauv tsis sib haum, thiab tsis tshua zoo. Nyob rau hauv cov txheej txheem welding, nws yog ib qho yooj yim los tsim cov teeb meem xws li lub qhov ncauj dawb, tawg thiab pores. Vim li ntawd, cov hlau cam khi hlua foob tau muaj kev xav tau siab dua rau ntawm kev txawj ntse ntawm lub chaw lag luam. Kev kho cov hlau cam khi hlua yuav muab faib ua ob hom: cov khoom siv ua ntej thiab txias.
Yuav kom ntseeg tau tias cov nyhuv welding, cov kev ntsuas nram qab no raug pom zoo rau txoj kev siv cov hlau casting welding thiab welding:
1. Ua ntej tshem tawm cov av, xuab zeb, dej, xeb thiab lwm yam kab mob ntawm cov pob txha caj dab, thiab ntsuas kev ntsuas xws li hom teeb meem, qhib qhov zawj, qhov tawg ntawm lub qhov thiab lub pas dej ua kom zoo li cas.
2. Rau qhov preheat weldment, thawj zaug kev sib txuas mus rau ntawm 500 ~ 600 ° C, xaiv qhov tsim nyog tam sim no, thiab txuas mus txuas ntxiv, yog li ntawd qhov kub thiab txias yog ib txwm khaws cia thaum lub sijhawm siv welding, thiab hmoov av asbestos yog liab kub lub xeev tom qab welding. Los yog lwm yam ntaub ntawv pov thawj, kom ua kom tau qis txias, yog qhov ua kom muaj graphite sai.
3. Ua kom cov dej ntub ua kom txias, ua kom tsis txhob muaj lub hauv paus ntawm lub hauv paus hlau thiab txo cov kab dawb dawb, nyob rau hauv kev siv, sim siv me me tam sim no, luv luv, luv hlaws, thiab luv hlaws (ntev npaum li cas hlaws feem ntau tsis tshaj). 50 hli) thiab tom qab vuam siv, hla lub weld los so lub plab kom tiv thaiv kev ntes. Thaum twg kub poob qis dua 60 ° C, weld nws dua.
4. Xyuam xim kom puv lub qhov dej kom zoo thaum kaw lub nraub qaum los tiv thaiv cov kab nrib pleev hauv lub qhov mob.
