Nka plaque yicyuma cyo kubika hamwe nubushobozi bwumuvuduko, igomba kuba ifite imbaraga nubukomezi, imikorere ikonje ikonje hamwe no kutumva neza. Nubwo ibyuma byazimye kandi bifite ubushyuhe Q690 bifite karubone yo hasi ihwanye kandi ifite ibintu byiza byuzuye, iracyafite imyumvire yo gukomera ugereranije nibindi byuma 50/60 kg byumuvuduko wubwato, kandi birasabwa kuvura ubushyuhe nyuma ya weld. Nyamara, umubare munini wubushakashatsi bwakozwe bwerekanye ko kubintu bikoreshwa mu gusudira ibyuma bya Q690, ubukana bw’ubushyuhe bwo hasi buzagenda bwangirika cyane nyuma yo kuvura ubushyuhe bwo kugabanya ubushyuhe, hamwe n’ubwiyongere bw’ubushyuhe bwo kuvura ubushyuhe no kugabanuka kwubushyuhe bw’ingaruka, kwangirika. yo gusudira gukoreshwa gukomera bizagaragara cyane. Niyo mpamvu, bifite akamaro kanini gutezimbere imbaraga-zikomeye, gukomera-gukomeye, hamwe nudukoni two gusudira two gusudira ibyuma bya Q690 kugirango dukoreshe neza ibyuma bya Q690 mubikoresho bitwara ingufu, kugabanya ibikoresho byibyuma, no kugabanya ibiciro byinganda.

4.Q690 ibyuma byo gusudira inkoni imashini yerekana imikorere

Icyitegererezo:
1. "X" yanditseho imyandikire itukura muri Standard ya Amerika na Standard yu Burayi byerekana ubwoko bwuruhu rwibiyobyabwenge.
2. GEL-758 ihuye na E11018-G na ISO 18275-B E7618-G A mubipimo bya AWS na ISO.
3. GEL-756 ihuye na E11016-G na ISO 18275-B E7616-G A mubipimo bya AWS na ISO.
Ibikoresho bya Q690 ibyuma byo gusudira ibyuma muburyo bwo gutunganya ubushyuhe

Icyitegererezo:

1. Ibipimo bijyanye na AWS na ISO nta bisabwa byo kuvura ubushyuhe kubicuruzwa byavuzwe haruguru. Ubuvuzi bwavuzwe haruguru bwavuzwe muri make bushingiye kumiterere ya tekiniki yabakiriya benshi kandi ni iyerekanwa gusa.
2. GEL-118M ifite ingaruka zikomeye kuri -40 ° C nyuma yo kuvura ubushyuhe, kandi ingaruka mbi kuri -50 ° C iragaragara.
3. Nyuma yo kuvura ubushyuhe, GEL-758 ifite ubukana buhebuje kuri -40 ° C, ubukana bwiza kuri -50 ° C, no kwangirika kugaragara ku bushyuhe buke kuri -60 ° C.
4. Ingaruka yubushyuhe bwo hasi ubukana bwa GEL-756 nyuma yo kuvura ubushyuhe ni buto, kandi ubukonje buke kuri -60 ° C buracyari bwiza.

Q690 ibyuma byo gusudira inkoni yo gusudira

1. Kubika ibikoresho byo gusudira:
Ibikoresho byo gusudira birasabwa kubikwa mubushyuhe burigihe nubushyuhe bwumutse, hanyuma bigashyirwa kuri pallets cyangwa mu gipangu, ukirinda guhura ninkuta nubutaka.

2. Kwitegura mbere yo gusudira:
Kuraho neza ubuhehere, ingese, irangi ryamavuta, nibindi hejuru yibikoresho fatizo, kandi wirinde ubushuhe bwo hejuru cyangwa guhura nimvura na shelegi.

3. Ingamba zitagira umuyaga:
Iyo gusudira, bigomba kwemezwa ko umuvuduko ntarengwa wumuyaga aho gusudira utarenga 2m / s. Bitabaye ibyo, hagomba gufatwa ingamba zo gukingira.

4. Gushyushya:
Birasabwa gukoresha ibikoresho byo gushyushya amashanyarazi kugirango ushushe akazi kugeza hejuru ya 150 ° C mbere yo gusudira. Ndetse na mbere yo gusudira, bigomba gushyuha hejuru ya 150 ° C.

5. Kugenzura ubushyuhe bwumuhanda no kumuhanda:
Mugihe cyose cyo gusudira, ubushyuhe bwa interpass ntibugomba kuba munsi yubushyuhe bwo gushyuha, kandi ubushyuhe bwateganijwe ni 150-220 ° C.

6. Gukuraho hydrogen nyuma yo gusudira:
Nyuma yo gusudira gusudira, hita wongera ubushyuhe bwo gushyushya amashanyarazi kugera kuri 250 ℃ ~ 300 ℃, komeza ushyushye mumasaha 2 kugeza kuri 4, hanyuma ukonje buhoro.
① Niba umubyimba wakazi ari ≥50mm, igihe cyo gufata kigomba kongerwa kugeza kumasaha 4-6, hanyuma ugakonja buhoro.
② Mubihe byubunini bunini no kwifata binini, indi dehydrogenation imwe irashobora kongerwamo nyuma yo gusudira kugeza kuri 1/2 cyubugari, hanyuma igakonja buhoro buhoro ubushyuhe bwa interpass.

7. Igorofa:
Birasabwa gukoresha ibyiciro byinshi kandi byinshi-gusudira, kandi umuvuduko wo gusudira ugomba kubikwa kumuvuduko uhoraho.
