Cov txheej txheem vuam hlau yog dav siv tsis yog hauv kev lag luam nkaus xwb tab sis kuj nyob hauv tsev. Qhov nrov tshaj plaws nyob rau tam sim no yog hluav taws xob vuam nrog lub electrode. Cov koob npe zoo li no yog vim qhov yooj yim ntawm cov khoom siv vuam, nrog rau qhov zoo ntawm kev sib txuas ntawm ntau yam hlau.
Nws tuaj yeem ua tiav qhov muaj zog thiab zoo vuam tsuas yog siv cov electrodes nrog cov txheej tshwj xeeb uas tiv thaiv lub pas dej ntawm cov pa oxygen. Cov hom zoo tshaj plaws ntawm rutile-coated electrodes yog nrov heev tsis yog ntawm cov kws paub txog vuam, tab sis kuj yog cov kws ua haujlwm hauv tsev. Qhov tseem ceeb tshaj plaws yog kom paub lawv cov yam ntxwv thiab cov khoom siv yooj yim.
Kev xaiv vuam electrodes
Qib siab ntawm lub zog ntawm kev sib koom ua ke yog nyob ntawm qhov kev xaiv raug ntawm cov khoom siv (electrode). Yog li ntawd, kev daws teeb meem zoo li no yuav tsum ua kom tau raws li qhov yuav tsum tau ua rau kev vuam zoo.
YogKev xaiv ntawm electrode rau vuam yuav tsum ua raws li cov hauv qab no:
- cov khoom siv cuab yeej cuab tam ntawm lub pas dej welding hlau yuav tsum phim cov khoom siv hauv paus;
- weld yuav tsum tsis txhob muaj qhov txias thiab kub tawg, piv txwv li muaj lub zog thev naus laus zis;
- versatility ntawm cov electrode kom vuam hauv ntau txoj haujlwm, nrog rau txhua yam tam sim no;
- thaum koom nrog cov hlau alloyed, cov khoom siv hluav taws xob yuav tsum muaj kev tiv thaiv corrosion siab ntawm cov seam thiab nws cov cua sov ua haujlwm;
- Yam tsawg kawg emission ntawm cov tshuaj lom thaum lub vuam.
Rutile coated electrodes ua tau raws li tag nrho cov khoom no thiab yog li ntawd feem ntau siv electrodes rau vuam ntau hom hlau.
Txoj kev ntawm electrodes
vuam electrode muaj ob ntu. Lub hauv paus ntawm lub electrode yog ib qho hlau bar ua los ntawm cov khoom siv tshwj xeeb. Ib txheej tshwj xeeb yog siv rau lub pas nrig, uas cuam tshuam rau txoj kev vuam. Lub luag haujlwm tseem ceeb ntawm cov hmoov txheej yog los tiv thaiv lub pas dej ua ke los ntawm kev phom sij ntawm oxygen.
SV-08 lossis SV-08A hlau, uas muaj cov ntsiab lus carbon tsawg, yog siv los ua ib qho ntxiv rau rutile-coated electrodes.
Cov electrodes zoo yuav tsum qhuav thiab tsis muaj kev puas tsuaj. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum khaws cov welding rods hauv qhov chaw qhuav thiab sov. Thaum dampness tshwm sim, rutile-coated vuam electrodes yog qhuav hauv qhov cub tshwj xeeb. Hauv tsev, rau lub hom phiaj no, koj tuaj yeem ua tausiv qhov cub.
Tshuaj muaj pes tsawg leeg ntawm electrode txheej
Ib hom ntawm electrodes, rau kev sib txuas zoo ntawm cov qauv hlau, raug xaiv nyob ntawm qhov kev tiv thaiv txheej ntawm cov khoom ntxiv. Plaub hom kev pab them nqi yog suav tias yog feem ntau:
- lub tsho tiv no muaj titanium, ferromanganese, quartz xuab zeb thiab spar;
- oxides ntawm manganese, hlau thiab silica yog ib feem ntawm cov kua qaub txheej;
- rutile-coated electrodes muaj txog 50% titanium dioxide (rutile);
- Cellulosic txheej muaj talc, organic resin, cellulose thiab ntau yam ferroalloys.
Cov tshuaj muaj pes tsawg leeg ntawm rutile electrodes muaj ntau yam ntxiv, uas tau muab faib rau hauv cov piv txwv hauv qab no:
- dextrin - 3%;
- magnesite - 10%;
- ferromanganese - 15%;
- feldspar - 25%;
- rutile – 47%.
Qhov zoo ntawm rutile electrodes
Tau kawg, feem pua ntawm cov khoom uas ua rau rutile electrodes yuav txawv me ntsis, nyob ntawm cov chaw tsim khoom.
Kev xaiv ntawm cov khoom siv tsim nyog rau kev ua tau zoo ntawm kev siv hluav taws xob arc vuam yog nyob ntawm cov khoom zoo ntawm cov electrodes siv.
Qhov zoo ntawm rutile-coated electrodes suav nrog cov khoom hauv qab no:
- cov pa tawm, thaum twgcombustion ntawm rutile electrodes, yog tsawg-tshuaj lom, uas yuav luag tsis ua mob rau lub welder kev noj qab haus huv;
- muaj peev xwm vuam rau ntawm qhov chaw yam tsis muaj kev kho ua ntej vim cov khoom tsis raug rau cov dej noo lossis xeb;
- tso nyiaj uas tshwm sim thaum vuam muaj cov khoom ntawm cov khoom siv hluav taws xob, yog li qhov hluav taws xob ntawm cov hluav taws xob yog nqa tawm yam tsis tau ua ntej chipping lub slag;
- vuam arc muaj qhov kub nyhiab ntawm ob qho tib si thaum ua haujlwm ntawm qhov ncaj qha tam sim no thiab ntawm qhov hloov pauv tam sim no;
- weld muaj cov qauv zoo nkauj, yog li nws tiv taus cov kab nrib pleb;
- me me hlau spatter txuag cov khoom siv;
- muaj peev xwm los tsim cov vuam hauv txhua txoj haujlwm.
Kev ua haujlwm ntawm rutile electrodes yog qhov zoo dua li lwm cov khoom siv coated.
Qhov tsis zoo ntawm rutile txheej
Raws li cov kws tshaj lij, muaj qee qhov tsis zoo ntawm kev siv rutile-coated electrodes, uas muaj feem xyuam nrog cov txheej txheem thev naus laus zis ntawm cov txheej txheem vuam.
Tsis muaj zog ntawm rutile electrodes suav nrog:
- qhov xav tau kom qhuav thiab calcining damp khoom;
- tswj nruj dua qhov loj ntawm qhov vuam tam sim no, vim nws qhov nce ntxiv ua rau cov hlau tawg;
- tsis tuaj yeem ua tau zoo ntawm cov vuam zoo ntawm cov pa roj carbon ntau, uas yog vim muaj cov yam ntxwv ntawm cov tub ntxhais.khoom.
Cov me me ntawm qhov tsis txaus ntawm rutile txheej, yuav luag tsis cuam tshuam rau kev siv dav dav ntawm cov khoom siv no.
Lub npe tseem ceeb ntawm rutile electrodes
Kev kos ntawm rutile electrodes yog qhia los ntawm tsab ntawv P, raws li lub npe ntawm cov khoom. Nyob rau hauv cov ntaub ntawv no, electrodes nrog ib tug rutile cellulose txheej yog feem ntau ntsib, uas yog ib tug sib tov hom consumable. Nyob rau hauv xws li cov khoom, ib feem ntawm lub rutile yog hloov los ntawm ib tug cellulose tivthaiv, uas tsuas yog burns tawm thaum lub sij hawm vuam txheej txheem, ho txo qhov tsim ntawm slag. Mixed electrodes ua rau ntsug vuam yooj yim dua.
Ntawm cov npe nrov tshaj plaws ntawm rutile electrodes, cov khoom hauv qab no tuaj yeem paub qhov txawv:
- MP-3.
- OK 46.00.
- OSS.
Tau kawm cov yam ntxwv tseem ceeb ntawm cov electrodes, nws tsis yog qhov nyuaj rau xaiv cov khoom siv rau ib txoj haujlwm tshwj xeeb.
MP-3 electrodes
Cov electrodes no suav hais tias yog feem ntau siv rau vuam. Lub ntsiab zoo ntawm MP-3 electrodes yog raws li nram no:
- yooj yim los ua ib qho seam hauv ntau txoj haujlwm;
- ncig arcing;
- muaj peev xwm ua tiav vuam hauv ntau hom;
- feem pua me me ntawm cov hlau poob thaum tawg.
Electrodes tau dav siv ob qho tib si rau kev vuam zoo thiab cov hlau tso rau ntawm cov khoom sib xyaw ua ke. RauKev siv cov khoom zoo, nws yog ib qho tsim nyog yuav tsum tau ua ntej ci rau ntawm qhov kub ntawm 160 ℃.
Electrodes OK 46.00
Electrodes yog tsim los ntawm Swedish kev txhawj xeeb, uas kuj muaj ceg nyob rau hauv Russia.
OK 46.00 electrodes muaj cov khoom zoo hauv qab no:
- muaj peev xwm weld ntub qhov chaw;
- weld muaj lub zog siab;
- Electrode annealing yog nqa tawm ntawm qhov kub thiab txias (80 ℃);
- siab arc stability tau tiav ntawm qhov tam sim no.
Nco ntsoov tias rutile-coated electrodes yog siv tau zoo tshaj plaws thaum vuam me me steels, tab sis qee zaus cov hlau tsis muaj hlau kuj tuaj yeem koom nrog. Ntau lub npe ntawm rutile electrodes feem ntau yog siv los ntawm cov neeg siv khoom tsis muaj kev paub, thiab kev sib txuas yog cov khoom siv zoo.
