Gusudira ni inzira aho ibikoresho by'ibikorwa bigomba gusudwa (ubwoko bumwe cyangwa butandukanye) bihujwe no gushyushya cyangwa igitutu cyangwa byombi, hamwe cyangwa bidafite ibikoresho byuzuza, ku buryo ibikoresho by'ibikorwa byahujwe hagati ya atome kugirango bibe bihoraho ihuriro. None ni izihe ngingo z'ingenzi n'ingamba zo kwirinda gusudira ibyuma?
Ibikoresho byo gusudira Xinfa bifite ibiranga ubuziranenge kandi buke. Ushaka ibisobanuro birambuye, nyamuneka sura:Abasudira & Gukata Inganda - Ubushinwa bwo gusudira & Gukata Uruganda & Abatanga isoko (xinfatools.com)
Ni ubuhe buryo bwa electrode bukoreshwa mu gusudira ibyuma bidafite ingese?
Inkoni zo gusudira zidafite ingese zirashobora kugabanwa muri chromium idafite ibyuma byo gusudira hamwe na chromium-nikel ibyuma bidafite ibyuma. Ubwo bwoko bubiri bwo gusudira bujuje ubuziranenge bwigihugu buzasuzumwa hakurikijwe ubuziranenge bwigihugu GB / T983-2012.
Ibyuma bya Chromium bidafite ingese bifite imbaraga zo kurwanya ruswa (acide oxyde, acide organic, cavitation), kurwanya ubushyuhe no kurwanya ruswa. Mubisanzwe byatoranijwe nkibikoresho byibikoresho byamashanyarazi, inganda zimiti, peteroli nibindi. Nyamara, chromium idafite ibyuma muri rusange ifite ubudodo bubi, bityo rero hakwiye kwitabwaho uburyo bwo gusudira, uburyo bwo kuvura ubushyuhe no guhitamo inkoni zo gusudira.
Inkoni zo gusudira za Chromium-nikel zifite ibyuma birwanya ruswa kandi zirwanya okiside kandi zikoreshwa cyane mu nganda z’imiti, ifumbire, peteroli, n’inganda zikoreshwa mu buvuzi. Kugirango wirinde kwangirika kw’imiterere bitewe no gushyushya, umuyoboro wo gusudira ntugomba kuba munini cyane, uri munsi ya 20% ugereranije n’ibyuma bya electrode ya karubone. Arc ntigomba kuba ndende cyane, kandi interlayers izakonja vuba. Isaro rito ryo gusudira rirakwiriye.
Ingingo z'ingenzi no kwitondera gusudira ibyuma
1. Koresha amashanyarazi afite vertical vertical iranga hanze, kandi ukoreshe polarite nziza kuri DC (insinga yo gusudira ihujwe na pole mbi)
1. Mubisanzwe birakwiriye gusudira amasahani yoroheje munsi ya 6mm. Ifite ibiranga imiterere myiza yo gusudira hamwe no guhinduranya gusudira.
2. Gazi ikingira ni argon ifite ubwiza bwa 99,99%. Iyo umuyoboro wo gusudira ari 50 ~ 150A, gazi ya argon ni 8 ~ 10L / min; iyo ikigezweho ari 150 ~ 250A, gazi ya argon ni 12 ~ 15L / min.
3. Uburebure bugaragara bwa tungsten electrode iva kuri gaz nozzle nibyiza ni mm 4 kugeza 5. Ahantu hafite gukingirwa nabi nko gusudira kuzuye, ni mm 2 kugeza kuri 3. Ahantu hafite ibinure byimbitse, ni mm 5 kugeza kuri 6. Intera kuva nozzle kumurimo muri rusange ntabwo irenze 15mm.
4. Kugirango wirinde ko habaho imyenge yo gusudira, ingese zose, irangi ryamavuta, nibindi bice byo gusudira bigomba gusukurwa.
5. Uburebure bwo gusudira arc nibyiza 2 ~ 4mm mugihe cyo gusudira ibyuma bisanzwe, na 1 ~ 3mm mugihe cyo gusudira ibyuma bitagira umwanda. Niba ari ndende cyane, ingaruka zo kurinda zizaba mbi.
6. Mugihe cyo guhuza ikibuno, kugirango wirinde uruhande rwinyuma rwamasaro yo hepfo yohanze kuba okiside, uruhande rwinyuma narwo rugomba kurindwa na gaze.
7. Kugirango gaze ya argon irinde neza pisine yo gusudira no koroshya imikorere yo gusudira, umurongo wo hagati wa tungsten electrode hamwe nakazi kakozwe aho gusudira bigomba muri rusange kugumana inguni ya 80 ~ 85 °, nu mfuruka hagati ya wuzuza insinga hamwe nubuso bwakazi bigomba kuba bito bishoboka. Muri rusange ni nka 10 °.
8. Umuyaga utagira umuyaga kandi uhumeka. Ahantu h'umuyaga, menya neza gufata ingamba zo guhagarika inshundura, kandi ufate ingamba zikwiye zo guhumeka mu nzu.
2. Ingingo zingenzi nuburyo bwo kwirinda MIG gusudira ibyuma bitagira umwanda
1. Koresha isoko iranga imbaraga zo gusudira, kandi ukoreshe polarite ihindagurika kuri DC (insinga yo gusudira ihujwe na electrode nziza)
2. Mubisanzwe, argon yera (99,99% yera) cyangwa Ar + 2% O2 irakoreshwa, kandi umuvuduko wikigereranyo nibyiza 20 ~ 25L / min.
3. Uburebure bwa Arc. MIG yo gusudira ibyuma bidafite ingese muri rusange isudira mugihe cyimiterere yinzibacyuho, kandi voltage igomba guhindurwa kuri arc ya metero 4 kugeza kuri 6.
4. Umuyaga utagira umuyaga. MIG gusudira byoroha byumuyaga, kandi rimwe na rimwe umuyaga urashobora gutera imyenge. Kubwibyo, ingamba zo kurinda umuyaga zigomba gufatwa ahantu hose umuvuduko wumuyaga uri hejuru ya 0.5m / sek.
3. Ingingo z'ingenzi hamwe no kwitondera ibyuma bitagira umwanda flux cored wire
1. Koresha imbaraga ziranga gusudira imbaraga, kandi ukoreshe polarite ihindagurika mugihe cyo gusudira DC. Urashobora gukoresha gusudira bisanzwe CO2 gusudira, ariko nyamuneka ugabanye umuvuduko wuruziga rwibiryo.
2. Gazi ikingira ni gaze karuboni ya gaze karuboni, kandi umuvuduko wa gazi ni 20 ~ 25L / min.
3. Intera ikwiye hagati yisonga ryo gusudira hamwe nakazi ni 15 ~ 25mm.
4. Uburebure bwumye bwumye, umuyoboro rusange wo gusudira ni nka 15mm mugihe umuyoboro wo gusudira uri munsi ya 250A, naho nka 20 ~ 25mm mugihe umuyaga wo gusudira uri hejuru ya 250A birakwiriye.
