Cam khwb cia hlau electrode cov lus qhia
Cam khwb cia hlau yog cov khoom siv tsis zoo weldability vim nws cov ntsiab lus carbon siab, lub koom haum tsis sib xws thiab tsis tshua muaj plasticity. Hauv cov txheej txheem vuam, lub qhov ncauj dawb, cov kab nrib pleb thiab qhov hws tau yooj yim tsim. Yog li ntawd, cam khwb cia hlau weld kho muaj siab yuav tsum tau nyob rau hauv lub welder cov kev txawj ntse. Kev kho cam khwb cia hlau vuam tuaj yeem muab faib ua ob hom: preheating thiab txias vuam.
Txhawm rau kom ntseeg tau tias cov nyhuv vuam, cov kev ntsuas vuam hauv qab no raug pom zoo rau kev siv thiab xaiv cov castings thiab qhov tsis xws luag rau cov khoom sib txawv.
EZC hom grey cam khwb cia hlau electrode
EZC hom steel tub ntxhais muaj zog graphitized txheej cam khwb cia hlau vuam pas nrig, tuaj yeem siv rau AC thiab DC. Qhov tsim nyog tus nqi ntawm graphitized ntsiab yog ntxiv rau cov tub ntxhais hlau cam khwb cia hlau electrode. Lub vuam tuaj yeem hloov mus ua grey cam khwb cia hlau thaum nws maj mam txias. Qhov txias txias yog ceev, thiab lub qhov ncauj dawb yog tsim thiab nws tsis yooj yim rau kev ua. Qhov txias txias muaj qhov cuam tshuam zoo rau lub tshuab ua haujlwm thiab cov qauv vuam. Yog li ntawd, cov txheej txheem ua haujlwm txawv ntawm qhov dav dav vuam electrode. Lub vuam pas nrig yuav tsum tau txuas txuas ntxiv vuam thiab kev txuag hluav taws xob tom qab vuam kom cov vuam qeeb.
Lub microstructure, cov khoom thiab xim ntawm grey cam khwb cia hlau weld yog qhov zoo ib yam li lub hauv paus hlau, tab sis vim yog cov yas tsis zoo, qhov vuam tsis tuaj yeem so thiab thermal stress crack kuj tsis zoo. Qhov tsis xws luag ntawm me me nyias-walled qhov chaw uas tsis tshua muaj rigidity yuav pre-rhuab, tab sis feem ntau yuav tsum tau preheated txog 400 degree rau re-welding, thiab ces maj mam txias tom qab vuam, thiaj li yuav tiv thaiv tau tawg thiab lub qhov ncauj dawb.
EZNi hom ntshiab nickel cam khwb cia hlau vuam pas nrig
EZNi hom yog ib qho ntshiab nickel core muaj zog graphitized hom coated hlau electrode, uas tuaj yeem siv rau txhua txoj haujlwm vuam. Thaum welding, lub vuam yuav tsis tau preheated. Nws yog ib hom electrode uas muaj kev ua tau zoo xws li tawg tsis kam, machinability, txheej txheem kev ua haujlwm thiab cov khoom siv kho tshuab hauv cam khwb cia hlau txias-welded electrode. Nws yog dav siv nyob rau hauv kev kho ntawm cam khwb cia hlau nyias qhov chaw thiab machined nto. vuam.
EZNiFe hom nickel hlau cam khwb cia hlau electrode
EZNiFe hom yog cam khwb cia hlau electrode nrog nickel-hlau core muaj zog graphitized txheej, uas tuaj yeem siv rau txhua txoj haujlwm vuam. Thaum vuam, lub vuam yuav tsis raug preheated, thiab muaj cov yam ntxwv ntawm lub zog siab, zoo plasticity, zoo heev tawg kuj, thiab zoo fusion nrog lub hauv paus hlau. Nws tuaj yeem siv los kho cov vuam ntawm qhov tseem ceeb grey cam khwb cia hlau thiab cov hlau nplaum.
EZNiCu hom nickel tooj liab cam khwb cia hlau electrode
EZNiCu hom yog cam khwb cia hlau electrode ntawm nickel-tooj liab alloy core nrog muaj zog graphite txheej. Nws tuaj yeem siv rau txhua txoj haujlwm vuam. Cov txheej txheem kev ua tau zoo thiab txiav kev ua tau zoo yog ze rau EZNi thiab EZNiFe hom electrodes, tab sis vim qhov loj shrinkage tus nqi, lub zog tensile ntawm cov hlau vuam yog tsawg, uas tsis haum rau kev kho cov casting nrog siab rigidity. Nws tuaj yeem raug preheated txog 300 degree ntawm qhov kub thiab txias. Nws yog siv rau kev kho vuam ntawm grey cam khwb cia castings uas tsis muaj zog yuav tsum tau thiab zoo plasticity yuav tsum tau.
