Amakuru - Intangiriro yo Kuzamura Urunigi rw'amanota: G80, G100 & G120

Kuzamura iminyururu n'imigozinibintu byingenzi mubikorwa byose byubwubatsi, inganda, ubucukuzi bwamabuye y'agaciro, ninganda zo hanze. Imikorere yabo ishingiye kubumenyi bwibikoresho nubuhanga bwuzuye. Urwego rwumunyururu wa G80, G100, na G120 rugaragaza ibyiciro byimbaraga zigenda ziyongera, bisobanurwa nimbaraga zabo ntoya (muri MPa) zikubye 10:

- G80: 800 MPa byibuze imbaraga zingana

- G100: 1.000 MPa byibuze imbaraga zingana

- G120: 1200 MPa byibuze imbaraga zingana

Aya manota yubahiriza amahame mpuzamahanga (urugero, ASME B30.9, ISO 1834, DIN EN818-2) kandi agenzurwa kandi akageragezwa kugirango yizere ko ari umutwaro uremereye, ubushyuhe bukabije, hamwe n’ibidukikije byangirika.

1. Ibikoresho na Metallurgie: Ubumenyi Inyuma Yumuzingo Uzamura

Imiterere yubukorikori bwiyi minyururu yo guterura ituruka kubihitamo neza no kuvura ubushyuhe.

Icyiciro	Ibikoresho shingiro	Kuvura ubushyuhe	Ibyingenzi Byingenzi	Ibiranga Microstructural
G80	Icyuma giciriritse	Kuzimya & Ubushyuhe	C (0.25-0.35%), Mn	Ikigereranyo cya martensite
G100	Imbaraga-nkeya-alloy (HSLA) ibyuma	Kuzimya	Cr, Mo, V.	Bainite nziza / martensite
G120	Icyuma cya HSLA	Kugaragaza neza	Cr, Ni, Mo, micro-ivanze Nb / V.	Gukwirakwiza karbide nziza cyane

Impamvu nuburyo ibyo bikoresho bifite akamaro:

- Kongera imbaraga.

-Kurwanya umunaniro: Microstructures nziza cyane muri G100 / G120 ibuza gutangira. G120 yuzuye martensite itanga ubuzima bwumunaniro uruta iyindi (> 100.000 cycle kuri 30% WLL).

- Kwambara Kurwanya: Gukomera hejuru (urugero, gukomera kwa induction) muri G120 bigabanya abrasion mubikorwa byinshi byo guterana amagambo nko gucukura amabuye y'agaciro.

Gusudira Porotokole yo Kuringaniza Urunigi

•Mbere yo gusudira:

o Sukura ahantu hamwe kugirango ukureho okiside / umwanda.

o Mbere yo gushyushya kugeza kuri 200 ° C (G100 / G120) kugirango wirinde hydrogene.

•Uburyo bwo gusudira:

o Gusudira Laser: Ku munyururu wa G120 (urugero, Al-Mg-Si alloys), gusudira ku mpande zombi bituma habaho uduce duhuza hamwe na HAZ ya H yo gukwirakwiza impagarara.

o Umuyoboro ushushe TIG: Kumurongo wibyuma (urugero, 10Cr9Mo1VNb), gusudira-pass nyinshi bigabanya kugoreka.

•Inama y'ingenzi:Irinde inenge za geometrike muri HAZ - ibibanza bikomeye byo gutangiriraho munsi ya 150 ° C.

Ibipimo bya nyuma yo gusudira (PWHT) Ibipimo

Icyiciro	Ubushyuhe bwa PWHT	Fata Igihe	Guhindura Microstructural	Gutezimbere Umutungo
G80	550-600 ° C.	Amasaha 2-3	Ikigereranyo cya martensite	Guhangayikishwa, + 10% gukomera
G100	740-760 ° C.	Amasaha 2-4	Gukwirakwiza karbide nziza	15% strength imbaraga z'umunaniro, HAZ imwe
G120	760-780 ° C.	Amasaha 1-2	Kubuza M₂₃C₆ gukomera	Irinde gutakaza imbaraga kuri temp nyinshi

Icyitonderwa:Kurenga 790 ° C bitera karbide gukomera → imbaraga / gutakaza imbaraga.

2. Kuzamura iminyururu Imikorere mubihe bikabije

Ibidukikije bitandukanye bisaba ibisubizo bifatika.

Kwihanganira Ubushyuhe:

- G80:Imikorere ihamye kugeza kuri 200 ° C; hamwe no gutakaza imbaraga byihuse hejuru ya 400 ° C kubera ubushyuhe bwo guhinduka.

- G100 / G120:Iminyururu Igumana imbaraga 80% kuri 300 ° C; amanota yihariye (urugero, hiyongereyeho Si / Mo) irwanya kwinjiza kugeza kuri -40 ° C kugirango ukoreshe arctique.

Kurwanya ruswa:

- G80:Gukunda ingese; bisaba amavuta kenshi mubidukikije.

- G100 / G120:Amahitamo arimo galvanisation (zinc plaque) cyangwa ibyuma bidafite ibyuma (urugero, 316L kubimera byo mu nyanja / imiti). Galvanized G100 ihanganira amasaha 500+ mugupima umunyu.

Umunaniro n'ingaruka zikomeye:

- G80:Birahagije imitwaro ihamye; ingaruka zikomeye ≈25 J kuri -20 ° C.

- G120:Ubukomere budasanzwe (> 40 J) kubera Ni / Cr wongeyeho; nibyiza byo guterura imbaraga (urugero, ubwato bwubwato).

3. Porogaramu-yihariye yo gutoranya ubuyobozi

Guhitamo icyiciro cyiza bitezimbere umutekano hamwe nigiciro-cyiza.

Porogaramu	Icyiciro Cyifuzo	Impamvu
Ubwubatsi rusange	G80	Igiciro-cyiza kuburemere buringaniye / ibidukikije byumye; urugero, gusebanya.
Offshore / Kuzamura Marine	G100 (Galvanised)	Imbaraga nyinshi + zo kurwanya ruswa; irwanya imyanda yo mu nyanja.
Ubucukuzi bw'amabuye y'agaciro	G120	Kugabanya imyambarire yo kwambara mugukoresha urutare; kurokoka ingaruka ziremereye.
Ubushyuhe bwo hejuru (urugero, Uruganda rukora ibyuma)	G100 (Ubushyuhe buvurwa)	Igumana imbaraga hafi y'itanura (kugeza 300 ° C).
Imyitozo ngororamubiri ikomeye	G120	Umunaniro urwanya kajugujugu cyangwa gushiraho ibikoresho bizunguruka.

4. Kunanirwa gukumira no gufata neza

- Kunanirwa k'umunaniro:Bikunze kugaragara muburyo bwo gupakira. G120 irwanya gukwirakwizwa gukabije kugabanya ibi byago.

- Gutobora ruswa:Kubangamira imbaraga; galvanised G100 ibice bimara 3 × birebire kurubuga rwinyanja na G80 idafunze.

- Kugenzura:ASME itegeka kugenzura buri kwezi kubice, kwambara> 10% diameter, cyangwa kuramba. Koresha ibice bya magnetiki bipimisha kuri G100 / G120.

5. Gushishikariza guhanga udushya hamwe nigihe kizaza

- Iminyururu y'ubwenge:Iminyururu ya G120 ifite ibyuma byifashishwa byo kugenzura imitwaro nyayo.

- Impuzu:Nano-ceramic coatings kuri G120 kugirango wongere ubuzima bwa serivisi mubidukikije.

- Ubumenyi bw'ibikoresho:Ubushakashatsi muburyo bwa austenitis ibyuma byo guterura (-196 ° C LNG).

Umwanzuro: Guhuza Iminyururu Urwego Kubyo Ukeneye

- Hitamo G80kubiciro-byoroheje, bitangirika static static.

- Kugaragaza G100kubora / dinamike ibidukikije bisaba imbaraga zingana kandi biramba.

- Hitamo G120mubihe bikabije: umunaniro mwinshi, abrasion, cyangwa guterura neza.

Icyitonderwa cya nyuma: Buri gihe shyira imbere iminyururu yemewe hamwe no kuvura ubushyuhe. Guhitamo neza birinda kunanirwa gukabije - siyanse yibintu niyo nkingi yo guterura umutekano.
