Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro w'icyuma kitagira umushongi wa ASTM A312 TP304H
Q: Ni irihe tandukaniro riri hagati ya TP304H na TP304L?
A: TP304H ifite karuboni nyinshi (0.04-0.10% ugereranije na ≤ 0.03% kuri 304L), ibyo bikaba bitanga imbaraga nyinshi zo gucika kw'izuba ku bushyuhe buri hejuru ya 550°C. 304L irwanya cyane ingese hagati y'udusimba nyuma yo gusudira. Ku bikoresho bifite ubushyuhe bwinshi (hejuru ya 550°C) n'imitsi, koresha TP304H. Ku bikoresho bisudiye bidakoresha ubushyuhe nyuma yo gusudira ku bushyuhe buri hasi, 304L ni yo ikwiriye.
Q: Ese TP304H ishobora gukoreshwa mu gihe yasuwede?
A: Ku bijyanye no gukoresha ingufu nke, ASTM A312 isaba gusudira umuti nyuma yo kuwutunganya (atari nyuma yo gusudira umurima). Ku gusudira umurima wa TP304H, ubushyuhe nyuma yo gusudira (gusudira umuti) muri rusange ntabwo ari ingirakamaro, bityo abakora ibikoresho benshi bakoresha icyuma cya 304L cyuzuza kugira ngo birinde kwangirika kwa HAZ. Womic itanga imiyoboro ya TP304H mu buryo bwo gusudira umuti; gusudira umurima bigomba gukoresha icyuma gikwiye (urugero, 308L) n'ubushyuhe buke.
Q: Ni ubuhe bushyuhe ntarengwa bwa serivisi ya TP304H?
A: TP304H ifite agaciro kemewe k’umuvuduko muri ASME Igice cya II, Igice cya D kugeza kuri 815°C (1500°F). Ariko, ku bushyuhe bw’igihe kirekire, ikoreshwa kugeza kuri 700°C. Hejuru ya 700°C, ingano ifite chromium nyinshi (309, 310, cyangwa nickel alloys) ishobora gukenerwa kugira ngo habeho ubudahangarwa bw’umwuka.
Q: Ni gute TP304H igereranywa na TP347H ku bijyanye na serivisi y'ubushyuhe bwinshi?
A: TP347H ifite ubushobozi bwo guhagarara neza kwa niobium kandi ifite imbaraga zo gucika kurusha TP304H mu bushyuhe bwinshi cyane, ndetse inarwanya ingese hagati y’udusimba nyuma yo gusudira. TP347H nayo irahenze cyane. Ku bikoresho byinshi by’amashanyarazi (superheaters kuri 550-650°C), TP304H irahagije kandi ihendutse. Ku miyoboro y’amashanyarazi ikoreshwa mu gutunganya amashanyarazi ikoreshwa mu gushyushya no gukaraba, TP347H ikunze kuba nziza.
Q: Ese gufunga imiyoboro ya TP304H birakenewe?
A: Yego, nk'uko ASTM A312 ibivuga. Gushyira umuti ku bushyuhe bwa 1040-1120°C hagakurikiraho kuzimya amazi birakenewe kugira ngo hashongeshwe karubide kandi hagerwe ku miterere yagenwe ya mekanike no kudakora neza kwangirika. Iyo hatabayeho guterwa umuti neza, umuyoboro ushobora kuba waragabanutse imbaraga zo gukurura no kwangirika hagati y’udusimba. Womic ikora umuti wose wo guterwa umuti ku miyoboro yose ya TP304H idakora neza.
Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri TP304H?
A: Ku bijyanye no gusudira TP304H, AWS A5.9 ER308H (ihuza karubone nyinshi) cyangwa ER308L (ikarubone nkeya) irashobora gukoreshwa. Ku bijyanye no guhuza imbaraga zo gukurura, ER308H irasabwa. Ariko, ku bijyanye no gusudira mu murima aho ubushyuhe nyuma yo gusudira budashoboka, ER308L ikunze gukoreshwa kugira ngo hirindwe ko ibintu byangirika. Uwashushanyije agomba kugena akurikije ubushyuhe bwa serivisi n'ibisabwa ku muvuduko.
Q: Igihe gisanzwe cyo gutanga umuyoboro wa TP304H udafite umugozi ni ikihe?
A: Iminsi 25-35 kuri CD (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri HF (umurambararo munini). Igihe cyo gukoresha TP304H gisa na 304L. Isuzuma ry’umuntu wa gatatu ryongeraho iminsi 7-14. Isuzuma ry’ibizamini riyongeraho iminsi 14-21.
Q: Ese TP304H isaba kugenzura ingano y'ibinyampeke kugira ngo serivisi yo gukurura igere?
A: Ku birebana na serivisi y'ubushyuhe bwinshi aho gukurura ari ikintu cyo kwitabwaho mu buryo bw'igishushanyo mbonera, Igice cya I na VIII bya ASME bisaba kugenzura ingano y'ingano. TP304H ubusanzwe ifite ingano y'ingano ya ASTM 5-7. Womic ishobora gutanga raporo zo gupima ingano y'ingano iyo ibisabye.
Icyitonderwa cy'umushinga - Imiyoboro y'amashanyarazi ya Superheater y'Uruganda rw'amashanyarazi rwa Aziya y'Amajyepfo y'Uburasirazuba (TP304H)
Igihugu:Tayilande (Rayong, Ikarita y'inganda za Ta Phut - uruganda rukoresha gazi)
Igipimo n'Icyiciro:ASTM A312 TP304H (idafite umushono) – hamwe n'ibizamini by'inyongera byo gucikamo ibice
Ingano n'ingano:
OD 114.3mm (4″) × Igipimo 80S (Uburemere 8.56mm) – metero 600 (hafi toni 11) – Ifite ubukonje
OD 168.3mm (6″) × Gahunda 80S (10.97mm WIT) – metero 400 (hafi toni 12) – Ishyushye cyane
OD 219.1mm (8″) × Gahunda 80S (12.70mm WIT) – metero 200 (hafi toni 8) – Ishyushye cyane
OD 60.3mm (2″) × Igipimo 80S (Uburemere bwa 5.54mm) – metero 1.000 (hafi toni 6) – Ifite ubukonje
Igiteranyo:Metero 2.200, hafi toni 37
Ibisobanuro:ASTM A312 TP304H ifite umushongi ugororotse, urimo amazi n'ibinyampeke, impande zirimo imirasire. Isuzuma rya Hydrostatic. Umuriro wa Eddy (CD) na UT (HF). PMI kuri buri muyoboro. Igipimo cy'ingano y'ibinyampeke gitegetswe (ASTM 5-7, cyagezweho 5.5-6.5). Ingufu za Charpy kuri -20°C (spec 27J, cyagezweho 80-130J). Isuzuma ry'ubushyuhe bwo hejuru kuri 600°C (spec: umusaruro ≥ 80 MPa, wagezweho 110-140 MPa; igenzura rya ≥ 200 MPa, ryagezweho 250-300 MPa). Isuzuma rya Creep rupture kuri 600°C, 50 MPa kuri 1,000h - nta gucika. Isuzuma rya Intergranular corrosion kuri ASTM A262 Practice E (byagaragaye ko byatsinze - nta gukangura). Igenzura rya gatatu ryakozwe na TÜV Thailand.
Porogaramu:Imitwe y'imashini zisohora amazi mu gikoresho cy'amashanyarazi gihujwe (turbine ya gaze + HRSG). Igice cy'imashini zisohora amazi mu gikoresho gitanga umwuka ku bushyuhe bwa 540°C, 10.5 MPa. Umuyoboro uhuza imashini zisohora amazi mu gikoresho gitanga umwuka ku gikoresho gitanga umwuka mwinshi. TP304H yatoranijwe kubera ko ifite ubwinshi bwa karuboni (0.06-0.08%) itanga imbaraga zo gukurura amazi kuri 540°C ugereranije na 304 isanzwe.
Ibibazo bya tekiniki n'ibisubizo:
Ingufu zo gukurura kuri 540°C na 10.5 MPa– TP304H ifite karuboni 0.06-0.08% n'ingano y'ibinyampeke ASTM 6 yatanze imbaraga zo gucika kw'inyuma kwa 55 MPa kuri 600°C mu masaha 100.000 (byari byateganyijwe). Womic yakoze ikizamini cyo gucika kw'inyuma kwa 1.000h kuri 600°C, 50 MPa – nta gucika kw'inyuma, uburebure bwose bwa 12%. Umukiriya arabyemererwa.
Kugenzura ingano y'ingano y'ibinyampeke kugira ngo habeho kubahiriza amategeko ya ASME Igice cya I– Gukoresha imiyoboro ya Superheater bisaba ingano ya ASTM y'ibinyampeke 5-7. Ingano ya Womic y'ibinyampeke igenzurwa binyuze mu bushyuhe bwo gukurura amazi (1070-1100°C) n'igipimo cyo gukonjesha. Ibisubizo: ASTM 5.5-6.5 ku cyuma gisanzwe, ASTM 6-7 ku isudira yo gukoresha ku ma coupons yo mu murima. Byemerwa.
Guhuza imbaraga zo gukurura icyuma hakoreshejwe ubutare– Inkingi zometse ku butaka zikenera imbaraga zo gukurura nk'iz'icyuma cyo hasi. Amacupa yometseho yapimwe na Womic (ifite GTAW yakozwe mu buryo bwa simulated hamwe na ER308L filler) kuri 600°C: itanga 100-120 MPa, tensile 220-260 MPa – iri hasi gato ariko iremewe. Umukiriya yemewe hakoreshejwe ER308L hamwe n'uburyo buhamye bwo kugenzura ubushyuhe (≤ 1.5 kJ/mm).
Ubudahangarwa bw'ingufu kuri 540°C– TP304H ikora igipimo cya Cr₂O₃ kirinda kuri 540°C. Umugore yakoze ikizamini cya oxidation (umwuka kuri 600°C mu masaha 500): kongera ibiro 0.10 mg/cm². Byemewe.
Uburyo bwo gusudira mu murima mu gusana superheater– Itsinda rishinzwe kubungabunga uruganda ryari rikeneye WPS yujuje ibisabwa. Womic yatanze ama coupons 20 yo gusudira hamwe na WPS hakoreshejwe GTAW, ER308L filler, gushyushya mbere ya 10-20°C, interpass ≤ 150°C, ubushyuhe bugera kuri 1.5 kJ/mm. Kuponi zanyuze kuri RT, PT, n'ubushyuhe buri hejuru kuri 600°C. Umukiriya yujuje ibisabwa.
Ibikoresho bijyana n'uruganda rw'amashanyarazi rwa Rayong– Imiyoboro yoherejwe iva i Shanghai ijya ku cyambu cya Laem Chabang, hanyuma ijyanwa mu ruganda rw’amashanyarazi. TÜV Tayilande yagenzuye imiyoboro ku cyambu. Toni 37 zose zatanzwe mu bicuruzwa 3 mu byumweru 8. Nta kutubahiriza amabwiriza.
Ibisubizo:Imiyoboro ya Superheater yashyizweho mu gihe cy'ibura rya 2 C 2024. Nyuma y'amezi 12 ikora kuri 540°C, 10.5 MPa, igenzura ryakozwe ku murongo ryagaragaje ko nta guhindagurika kw'amazi, nta gupima ogisijeni, kandi nta kwangirika kwabyo byagaragaye. Uru ruganda rwiteze kumara imyaka irenga 20 rukora. Womic Steel ubu ni yo itanga ryujuje ibisabwa kugira ngo uru ruganda rubone amashanyarazi ashyushye cyane mu gihe kizaza.
