Nka soko yingufu zisukuye, ingufu zumuyaga zateye imbere byihuse mumyaka yashize. Hamwe nogutezimbere ibikoresho byamashanyarazi yumuyaga, ibyuma byakoreshejwe bigenda byiyongera, kandi bimwe byarengeje 100mm, ibyo bikaba bitanga ibisabwa hejuru yo gusudira. Kugeza ubu, Q355 cyangwa DH36 ikoreshwa cyane mubikoresho bikoresha ingufu z'umuyaga, kandi uburyo bwo gusudira muri rusange buhitamo flux cored wire wire welding (FCAW) hamwe no gusudira arc (SAW).
Mubikorwa byo gukora umunara wa turbine yumuyaga, ibice byiza bikunze kugaragara kumurongo wa fusion cyangwa ubushyuhe bwibasiwe na zone nyuma yo gusudira kumuryango wumuryango, kandi icyapa kinini cyicyuma, niko bigenda byangirika. Impamvu iterwa no kurenza urugero rwimyitwarire, ubushyuhe bwo gusudira, urukurikirane rwo gusudira, guteranya hydrogène, nibindi, bityo rero bigomba gukemurwa mumirongo myinshi nkibikoresho byo gusudira, urukurikirane rwo gusudira, ubushyuhe bwo gusudira, kugenzura inzira, nibindi.
1 、 Guhitamo ibikoreshwa byo gusudira
Kuberako igice cyo gusudira ari ingenzi cyane, birakenewe guhitamo ibikoresho byo gusudira bifite ibintu bike byanduye, ubukana bwiza hamwe no guhangana neza, nka GFL-71Ni (GB / T10045 T494T1-1 C1 A, AWS A5.20 E71T-1C -J).
Imikorere isanzwe y'ibicuruzwa bya GFL-71Ni:
Ibintu birimo umwanda muke cyane, P + S ≤0.012% (wt%) irashobora kugenzurwa.
Plast Plasitike nziza yo kuramba, kuramba nyuma yo gucika 27%.
Effect Ingaruka nziza zikomeye, -40 ° C imbaraga zo kwinjiza ≥ zirenga 100J.
Performance Imikorere myiza ya CTOD.
Hyd Diffusion hydrogen irimo H5 cyangwa munsi yayo.
2 control Igenzura ryo gusudira
(1) Gusudira ubushyuhe no guhuza imiyoboro hagati yubushyuhe
Ukoresheje ibipimo bifatika hamwe nubunararibonye bwashize, birasabwa guhitamo ubushyuhe n'ubushyuhe hagati:
● 20 ~ 38mm z'ubugari, ubushyuhe bukabije hejuru ya 75 ° C.
● 38 ~ 65mm z'ubugari, ubushyuhe bukabije hejuru ya 100 ° C.
● Uburebure burenga 65mm, ubushyuhe bukabije hejuru ya 125 ° C.
Mu gihe cy'itumba, gutakaza ubushyuhe bigomba gutekerezwa, bityo bigomba guhindurwa na 30 ~ 50 ° C hashingiwe kuri ibyo.
(2) Igicapo kigomba guhora gishyuha mugihe cyo gusudira kugirango ubushyuhe buhagije hagati yimiyoboro
● 20 ~ 38mm z'ubugari, birasabwa kugenzura ubushyuhe buri hagati yimiyoboro 130 ~ 160 ° C.
● 38 ~ 65mm z'ubugari, birasabwa kugenzura ubushyuhe buri hagati yimiyoboro 150 ~ 180 ° C.
● Uburebure burenga 65mm, birasabwa kugenzura ubushyuhe buri hagati yimiyoboro 170 ~ 200 ° C.
Igikoresho cyo gupima ubushyuhe nibyiza gukoresha ibikoresho byo gupima ubushyuhe bwo guhuza, cyangwa ikaramu idasanzwe yo gupima ikaramu.
3 control Igenzura ryo gusudira
| Welding wire Diameter | Ibipimo bisabwa | Shyushya |
| 1,2 mm | 220-280A / 26-30V 300mm / min | 1.1-2.0KJ / mm |
| 1,4 mm | 230-300A / 26-32V 300mm / min | 1.1-2.0KJ / mm |
Icyitonderwa 1: Umuyoboro muto ugomba guhitamo gusudira hepfo, kandi igifuniko cyuzuye gishobora kuba kinini, ariko ntigomba kurenza agaciro kasabwe.
Icyitonderwa 2: Ubugari bwisaro imwe yo gusudira ntigomba kurenga 20mm, kandi isaro ryo gusudira rigomba gutondekwa ukurikije uko ibintu bimeze. Iyo groove ari ngari, gusudira-kunyuramo byinshi bigomba gukoreshwa, bifite akamaro ko gutunganya ibinyampeke.
4. Kugenzura gahunda yo gusudira
Nibyiza gukoresha gusudira-abantu benshi kubudodo bwa buri mwaka, bishobora kugabanya cyane guhangayika kugabanuka, kandi gusudira-abantu 4-gusudira ni byiza kuruta gusudira abantu 2.
5 removal Gukuraho hydrogène hagati yo gusudira
Gukuraho hydrogène mu gice cyo hagati ni ingamba zafashwe zirwanya ikwirakwizwa rya hydrogène ikwirakwizwa mu gusudira amasahani manini. Ubushakashatsi bwerekana ko ingaruka zigaragara ku masahani manini arenze 70mm. Igikorwa cyo gukora nuburyo bukurikira:
Kureka gusudira hafi 2/3 by'isaro ryose.
● Dehydrogenation 250-300 ℃ × 2 ~ 3h.
● Komeza gusudira kugeza kurangiza hydrogene.
● Nyuma yo gusudira, upfundikishe ipamba hanyuma ukonje buhoro buhoro ubushyuhe bwicyumba.
6. Ibindi bibazo bikeneye kwitabwaho
● Mbere yo gusudira, ibishishwa bigomba kuba bifite isuku kandi bifite isuku.
Ests Ibimenyetso bya swing bigomba kwirindwa bishoboka. Birasabwa gukoresha isaro igororotse igororotse hamwe nuburyo bwinshi bwo gusudira.
● Uburebure bwagutse bwinsinga yo gusudira hepfo ntibugomba kurenza 25mm. Niba igikoni cyimbitse cyane, nyamuneka hitamo uruziga.
● Nyuma yo gukora isuku ya karubone, ibara ryicyuma rigomba guhanagurwa mbere yo gukomeza gusudira.
Dufite umubare munini wo gukoresha ingero zo gusudira zikoreshwa mu nganda zikoresha ingufu z'umuyaga, urakaza neza kubaza!
