Q: Ni ubuhe bushyuhe ntarengwa bwa serivisi ya TP309?
A: TP309 ikwiriye gukoreshwa mu mwuka kugeza kuri 1000°C (1830°F) kandi irwanya ogisijeni neza. Kugira ngo ikoreshwe mu buryo buhoraho, ishobora kwihanganira kugeza kuri 1035°C. Hejuru ya 1000°C, ubwiyongere bw'ubushyuhe buriyongera; TP310 (25Cr-20Ni) irasabwa gukoreshwa mu gihe cy'ubushyuhe bwa 1100°C.
Q: Ni gute TP309 igereranywa na TP304 ku bijyanye na serivisi y'ubushyuhe bwinshi?
A: TP309 ifite chromium iri hejuru (23% ugereranyije na 18%) na nikeli (13% ugereranyije na 8%), itanga ubudahangarwa bwiza cyane bwo kurwanya okiside (kugeza kuri 1000°C ugereranije na 850°C kuri 304). TP309 kandi ifite ubudahangarwa bwiza bwo kurwanya kaburiseri na sulfide. Kugira ngo serivisi igere kuri 850°C, TP309 niyo nziza.
Q: Ese TP309H ni ngombwa ku miyoboro irabagirana mu itanura ritunganya ubushyuhe?
A: Ku miyoboro irabagirana ikora hejuru ya 650°C mu gihe cy'ubushyuhe (mu bihe by'ubushyuhe), TP309H irasabwa kuko ingano yayo ya karuboni nyinshi itanga imbaraga nyinshi zo gucika kw'ubushyuhe. Ku bijyanye no gukoresha stress nke (urugero, uduseke dushyushya, ibikoresho), TP309S irakwiriye.
Q: Ese TP309 isaba gusukurwa nyuma yo gutunganywa?
A: ASTM A312 isaba gufunga imiyoboro idafite umugozi. Kuri TP309S, gufunga imiyoboro idafite umugozi birakenewe kugira ngo bihuze n'imiterere ya mekanike n'ubudahangarwa bw'ingufu. Womic ikora gufunga imiyoboro yose idafite umugozi ya TP309.
Q: Igihe gisanzwe cyo gutanga umuyoboro wa TP309 udafite umugozi ni ikihe?
A: Iminsi 25-35 kuri CD (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri HF (umurambararo munini). TP309H ishobora kugira igihe kirekire cyo kuyobora bitewe n'uburyo bwihariye bwo kubona billet.
Q: Ese TP309 ishobora gukoreshwa mu gutanga serivisi ya aside sulfuri cyangwa hydrochloric?
A: Oya. TP309 ntabwo yagenewe serivisi ya aside; ni aloyi ikoresha ubushyuhe bwinshi. Kugira ngo ikoreshwe muri aside ku bushyuhe bw'icyumba, koresha 304L, 316L, cyangwa duplex. TP309 ni iyo kurwanya ogisijeni ku bushyuhe bwinshi, ntabwo ari iyo kurwanya ingese mu binyabutabire ku bushyuhe buri hasi.
Icyitonderwa cy'umushinga - Imiyoboro igabanya ubushyuhe n'imiyoboro ikonjesha (Viyetinamu)
Igihugu:Vietnam (Intara ya Ha Nam)
Igipimo n'Icyiciro:ASTM A312 TP309H (idafite umushono)
Ingano n'ingano:
OD 168.3mm (6″) × Igipimo 80 (10.97mm WIT) – metero 500 (hafi toni 15) – Ishyushye cyane
OD 219.1mm (8″) × Igipimo 80 (12.70mm WIT) – metero 200 (hafi toni 10) – Ishyushye cyane
OD 88.9mm (3″) × Igipimo 40 (Uburemere bwa 5.49mm) – metero 400 (hafi toni 3.5) – Ifite ubukonje
Igiteranyo:Metero 1.100, hafi toni 28.5
Ibisobanuro:ASTM A312 TP309H ifite umushongi ugororotse, urimo amazi n'ibinyampeke, impera zikozwemo. Isuzuma rya Hydrostatic. Umuriro wa Eddy (CD) na UT (HF). PMI kuri buri muyoboro. Isuzuma rya ngombwa ryo gukurura ubushyuhe buri hejuru kuri 800°C (nibura 100 MPa, ryageze kuri 130-155 MPa). Isuzuma rya oxidation (umwuka kuri 950°C mu gihe cy'amasaha 500) - kongera ibiro < 0.5 mg / cm². Isuzuma rya corrosion intergranular kuri ASTM A262 Practice E (pass). Ingano y'ingano ya ASTM 6-7. Isuzuma rya gatatu ryakozwe na TÜV Vietnam.
Porogaramu:Gusimbuza umuyoboro wa riser na grate cooler tubes mu ruganda rwa sima (ikorwa rya clinker). Umuyoboro wa riser utwara imyuka ishyushye yo mu itanura (850-950°C) irimo ivumbi (uduce twa sima clinker) n'imyuka itwika (CO₂, SOx, NOx). Imiyoboro ya 304H yabanje yarananiwe nyuma y'imyaka 3 bitewe no kwangirika kwa oxidation, carburisation, na creep deformation. TP309H yatoranijwe kubera chromium yayo iri hejuru (23%) itanga ubushobozi bwo kurwanya oxidation kugeza kuri 1000°C n'imbaraga zo gukurura cyane.
Ibibazo bya tekiniki n'ibisubizo:
Gushyira ogisijeni no gushyiramo kaburiseri kuri 850-950°C– TP304H (18% Cr) ipima vuba cyane hejuru ya 850°C. TP309H ifite 23% Cr ikora igipimo cya Cr₂O₃ gihamye kurushaho, irwanya ogisijeni na kaburizeti. Umugore yakoze ikizamini cya ogisijeni (umwuka kuri 950°C mu gihe cy'amasaha 500): kwiyongera ibiro 0.6 mg/cm² (ugereranije na 304H isanzwe ya 4.5 mg/cm²). Umukiriya arabyemerewe.
Imbaraga zo kwiruka ku bushyuhe bwinshi– Umuyoboro w’amazi uri hejuru y’amazi ufite uburemere bwawo bwite kandi ubushyuhe bushobora kwaguka. TP309H ifite karuboni 0.07-0.09% yatanze imbaraga nyinshi zo gukurura. Ubushyuhe bwinshi bwo gukurura kuri 800°C: umusaruro ni 135-155 MPa, gukurura ni 210-230 MPa. Isuzuma ry’imvura (1.000h kuri 800°C, 35 MPa) – nta gucika.
Ubudahangarwa ku munaniro uterwa n'ubushyuhe– Ifuru ya sima irahagarara/itangira gutera ubwihindurize bw'ubushyuhe. TP309H ifite imiterere mito yateweho umuti (utubuto duto twa ASTM 6-7) yatanze ubushobozi bwo kurwanya umunaniro w'ubushyuhe. Nta gucikagurika kwagaragaye nyuma y'inshuro 500 z'ubushyuhe mu isuzuma rya laboratwari.
Uburyo bwo gusudira mu murima– Gahunda yo gusudira uruganda rwa sima igihe gito cyo gusudira. Womic yatanze WPS ikoresheje GTAW hamwe n'icyuma gishyushya ER309L, gishyushya 10-20°C, interpass ≤ 150°C, ubushyuhe bugera kuri 1.5 kJ/mm. Kuponi 15 zo gusudira zanyuze kuri RT, PT, n'ubushyuhe buri hejuru.
Ibikoresho bijya i Ha Nam– Imiyoboro yoherejwe iva i Shanghai ijya ku cyambu cya Haiphong, hanyuma ikamyo ijya aho iherereye mu birometero 100. TÜV yagenzuwe ku cyambu. Toni 28.5 zose zatanzwe mu bicuruzwa 2 mu byumweru 6. Inyandiko zakirwa nta kibazo.
Ibisubizo:Umuyoboro mushya wa TP309H wo kuzamuka n'imiyoboro ikonjesha byashyizweho mu gihe cyo guhindura imikorere mu 2023. Nyuma y'amezi 18, igenzura ryagaragaje ko ogisijeni ari ntoya cyane (ubugari bwa skeli < 0.1mm) kandi nta guhindagurika cyangwa kwangirika kw'amazi byacitse. Umukiriya avuga ko igihe cyo gukora ari imyaka 8-10 (ugereranije n'imyaka 3 kuri 304H). Womic Steel ubu ni yo isabwa cyane mu gutanga ibikoresho by'ubushyuhe bwinshi by'uru ruganda rwa sima.
