Ndi ma electrode ati omwe amagwiritsidwa ntchito powotcherera zitsulo zosapanga dzimbiri?

Kusankha maelekitirodi oyenera olumikizira zitsulo ndikofunikira kwambiri pa ntchito zachitsulo chosapanga dzimbiri kuyambira zida za kukhitchini mpaka zida za mankhwala kuti apewe maelekitirodi ofooka, dzimbiri, kapena kusintha mtundu. Maelekitirodi odziwika kwambiri ndi ochokera ku mndandanda wa E308, E309, E316, ndi E312. Kusankha koyenera kumadalira mtundu wa chitsulo chosapanga dzimbiri komanso zofunikira pa ntchitoyo, kuonetsetsa kuti maelekitirodiwo ndi olimba, osapsa, komanso ovomerezeka ndi maso.

Kumvetsetsa Ma Electrode Osapanga Zitsulo Zosapanga Zitsulo

A Chitsulo chosapanga dzimbiri chowotcherera maelekitirodindi ndodo yachitsulo yokutidwa ndi flux yopangidwa kuti igwirizane ndi kapangidwe ka chitsulo choyambira. flux imakhazikika mu arc, imateteza dziwe losungunuka la weld ku mpweya ndi nayitrogeni, ndipo imathandiza kupanga slag yoteteza. Chinsinsi cha kupambana ndikufananiza kuchuluka kwa alloy ya electrode ndi mtundu wa chitsulo chosapanga dzimbiri chomwe mukuwotcherera. Izi zimasunga kukana dzimbiri komanso mphamvu zamakina za weld yomalizidwa.

Mitundu Yotchuka ya Ma Electrode a Zitsulo Zosapanga Zingwe Zodziwika

Nayi chitsogozo cha zomwe zimagwiritsidwa ntchito kwambiriChitsulo chosapanga dzimbiri chowotcherera maelekitirodimitundu:

1. E308L-16

• Zabwino Kwambiri: Kulukira zitsulo zosapanga dzimbiri za austenitic 304 ndi 304L, zomwe zimagwiritsidwa ntchito kwambiri popereka chakudya, zomangamanga, komanso kupanga zinthu zambiri.
• Chifukwa Chake: “L” imasonyeza kuchuluka kwa mpweya wochepa, zomwe zimachepetsa mpweya wa carbide ndikuletsa dzimbiri m'dera lomwe lakhudzidwa ndi kutentha. Iyi ndi electrode yogwira ntchito yonse.

2. E316L-16

• Zabwino Kwambiri: Kulukira zitsulo zosapanga dzimbiri za 316 ndi 316L, zomwe zili ndi molybdenum.
• Chifukwa: Molybdenum yowonjezerayi imapereka mphamvu yolimbana ndi dzimbiri, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito ndi mankhwala, zam'madzi, komanso zamankhwala komwe kukhudzana ndi ma chloride ndi vuto.

3. E309L-16

• Zabwino Kwambiri: Zowotcherera zosiyana, monga kulumikiza chitsulo chosapanga dzimbiri ndi chitsulo chofewa kapena kuphimba chitsulo cha kaboni ndi pamwamba pa chitsulo chosapanga dzimbiri. Zimagwiritsidwanso ntchito powotcherera 309 chosapanga dzimbiri chokha.
• Chifukwa: Ili ndi chromium ndi nickel yambiri, zomwe zimathandiza kuchepetsa mpweya kuchokera ku chitsulo chofewa ndikuletsa kupangika kwa malo olimba komanso ofooka a martensitic mu weld.

4. E312-16

• Zabwino Kwambiri: Kulukira zitsulo zosiyana zomwe zili ndi aloyi wambiri kapena kuphatikiza zitsulo zosapanga dzimbiri zosadziwika komwe kungayambitse ming'alu.
• Chifukwa: Imapanga malo olumikizira zitsulo okhala ndi ferrite yambiri, yomwe imapereka kukana bwino ku ming'alu yotentha ndipo imalekerera kwambiri zitsulo zosiyanasiyana.

Zinthu Zofunika Pakusankha Electrode Yoyenera

1.Yesani kufananiza Giredi: Nthawi zonse yesani kufananiza electrode ndi giredi yachitsulo choyambira. Yang'anani chitsimikizo cha zinthuzo kapena gwiritsani ntchito spectrometer ngati simukudziwa.
2. Ganizirani za Malo Ogwirira Ntchito: Kodi chotenthetseracho chidzakumana ndi kutentha kwambiri, asidi, kapena madzi amchere? Pamalo ovuta, 316L nthawi zambiri imafunika.
3. Malo Owotcherera: Chiganizo cha “-16″ chimasonyeza mtundu wa flux ndipo kuti electrode ndi yoyenera malo onse owotcherera (athyathyathya, opingasa, oimirira, pamwamba).
4. Kumaliza ndi Kuyeretsa: Pa ntchito zomwe ukhondo kapena mawonekedwe ndizofunikira (monga mkaka kapena zolumikizira zowoneka), onetsetsani kuti mukugwiritsa ntchito ma electrode opangidwira mkanda wosalala, wosavuta kuyeretsa wopanda kudontha kwambiri.

Malangizo Ofunika Kwambiri Othandizira Kuwotcherera Zitsulo Zosapanga Dzimbiri Kuti Zikhale Zopambana

Chitsulo chosapanga dzimbiri chimatulutsa kutentha pang'onopang'ono kuposa chitsulo cha kaboni ndipo chimasokonekera mosavuta. Tsatirani njira zabwino izi:

1. Gwiritsani ntchito Lower Heat Input: Sungani amperage kumapeto kwa mlingo woyenera ndipo gwiritsani ntchito njira ya stringer bead kuti muchepetse kusungunuka kwa kutentha ndi kusokonekera.
2. Sungani Utali Waufupi wa Arc: Izi zimathandizira kuteteza mpweya ndikuchepetsa chiopsezo cha ma porosity.
3. Tsukani Mosamala: Chotsani mafuta onse, mafuta, utoto, ndi inki zolembera pamalo olumikizirana. Gwiritsani ntchito burashi yachitsulo chosapanga dzimbiri kuti mupewe kuipitsidwa ndi chitsulo cha kaboni.
4. Gwiritsani Ntchito Kutsuka Msana (pa ma weld ofunikira): Mukalumikiza chitoliro kapena pomwe mbali yakumbuyo ikugwiritsidwa ntchito, gwiritsani ntchito mpweya wosagwira ntchito kumbuyo kuti mupewe shuga mkati mwa weld wouma komanso wokhuthala womwe umapha kukana dzimbiri.

Zogwiritsidwa Ntchito Zowotcherera Zabwino Kwambiri

Kwa odulira, opanga zinthu, ndi magulu okonza, kusinthasintha kwa ma electrode anu kumakhudza mwachindunji ubwino wa weld, kupanga bwino, ndi mtengo wa projekiti. Ndodo zolakwika kapena zosapangidwa bwino zingayambitse kusinthidwa, kulephera, ndi mavuto achitetezo. Mukapeza ntchitoChitsulo chosapanga dzimbiri chowotcherera maelekitirodiAkatswiri nthawi zambiri amaika patsogolo ogulitsa omwe amapereka ntchito yodalirika komanso zabwino zogulira.

Opanga omwe amatsatira miyezo yapadziko lonse lapansi amapereka chitsimikizo cha khalidwe ndi magwiridwe antchito. Kwa ma workshop, malo opangira zombo, kapena makampani omanga omwe amachita mapulojekiti akuluakulu kapena obwerezabwereza, mwayi wopeza mitengo yopikisana komanso netiweki yodalirika yapadziko lonse lapansi ingathandize kuchepetsa ntchito ndikukonza bajeti. Kugwirizana ndi wogulitsa yemwe ali ndi zida zambiri zowotcherera kumathandizanso kuti kasamalidwe ka zinthu kakhale kosavuta, kuonetsetsa kuti elekitirodi yoyenera ikupezeka nthawi zonse pantchito yomwe ilipo.

Malangizo Omaliza
Kusankha ma electrode oyenera n'kofunika kwambiri. Pa chitsulo chosapanga dzimbiri cha 304/304L, yambani ndi E308L-16. Pa ntchito ya m'madzi kapena mankhwala ndi chitsulo cha 316, gwiritsani ntchito E316L-16, koma nthawi zonse tsimikizirani chitsulo choyambira ndi zofunikira kaye. Kuwotcherera bwino kumadaliranso kuwongolera kutentha ndi kusunga ukhondo wabwino. Pogwiritsa ntchito ma electrode oyenera komanso njira yowotcherera yachitsulo chosapanga dzimbiri, mutha kupanga ma weld oyera, amphamvu, komanso osapsa omwe amakwaniritsa miyezo yapamwamba.
