Umphumela We-Fine-Grained Band Ngo-690 Ingxubevange Kokuzihlanganisa Bar On The Structure Of Finished Pipe

Ingxubevange 690 kuyinto ingxubevange-based ukugqwala ukumelana ingxubevange. It hhayi kuphela has omuhle kakhulu ukucindezeleka ukugqwala ukumelana, kodwa futhi unamandla kakhulu kuqhathaniswa, ezinhle isakhiwo ukuzinza kanye omuhle ukucutshungulwa izici. Isibe yisikhungo esikhulu samandla enuzi esithuthukile se-PWR ekhaya naphesheya. Izinto zokuzikhethela zamashubhu wokudlulisa ukushisa wama-generator kagesi Inqubo yokwenza ithubhu ka-690 ingxubevange yokudlulisa ukushisa ithubhu yilawa: ibha yokuzihlanganisa → ukushisa okushisayo → ukugoqa okubandayo kwe-billet → ukuthwebula okuphakathi "TT").

Izazi zasekhaya nakwamanye amazwe ziye zafunda ngemiphumela yokwelashwa kwesixazululo kanye nokwelashwa okukhethekile kokushisa ngokufana, i-carbide precipitation morphology, isakhiwo semingcele yamabele kanye nokumelana nokugqwala kwamashubhu we-690 alloy aqedile ukudluliswa kokushisa, kepha ukwakheka kwemigoqo yenkohliso yenkohliso Kunemibiko embalwa kakhulu kumabhande akhiwe kahle nemiphumela yawo esakhiweni samapayipi. Ngenxa yalokhu, abacwaningi bahlaziye ukwakheka kwebha yomgunyathi engu-690 esetshenziswe kuthubhu lokudlulisa ukushisa kukhiqizi wamandla enuzi, futhi benza isivivinyo sokwelashwa kokushisa kanye nesakhiwo sebha yomgunyathi enesakhiwo sebhande esinezinhlamvu ezinhle ngokusho inqubo yokushisa ngenqubo eshisayo ye-extrusion. Ihlaziye futhi yahlaziya ithonya layo esakhiweni seshubhu eliphakathi nendawo futhi isimo se-TT siqedile ukwakhiwa kweshubhu ekuqhubekisweni okulandelayo.

Ibha yomgunyathi engu-690 yokuhlola yanikezwa ngumenzi wasekhaya. Ukuphela kwebha yomgunyathi eyi-690 kunqanyuliwe, futhi kukhethwe isampula elimele ukubona isakhiwo sokuqala sendawo ende. Ukuze ufunde ngomthelela wenqubo yokushisa esakhiweni sebha ehlanganisiwe ngesikhathi senqubo yokushisa, ibha yomgunyathi engu-690 yaphathwa ukushisa ngokuya ngale nqubo yokushisa, okungukuthi, isampula yebhagi eyakhiwe (20mm × 20mm × 20mm) yashiswa ngo-950 ℃ nge-2h, namanzi selehlile, Lungisa isampula ye-metallographic ukuze ubuke ukwakheka kwayo kwe-longitudinal; lapho-ke, iqoqo lamasampuli ligcinwa kuqala ku-950 ° C imizuzu eyi-10, bese liphakanyiswa laya ku-1200 ° C imizuzu engu-5, bese lipholisa amanzi, bese isampula ye-metallographic ilungiselelwe ukugcina ukwakheka kwayo kwe-longitudinal. Ngasikhathi sinye, kwafakwa amashubhu aphakathi nendawo kanye namashubhu aqediwe we-TT ngokuya ngenqubo yokuhambisa ukushisa kokushisa kwale nqwaba yemigoqo yomgunyathi, futhi kwenziwa ngayo ukuhlaziywa kwe-longitudinal microstructure kubo.

Ukuhlolwa kutholakale ukuthi kunebhendi ebunjiwe ebunjiwe ngendlela engajwayelekile ngendlela ye- "sandwich" esakhiweni sokuqala sebha yomgunyathi. Amabhande amabi futhi anezinhlamvu ezinhle ahlukanisiwe, futhi osayizi bezinhlamvu zamabhande ahlukene acolisisiwe ngokufanayo bayafana. Ububanzi bamabhande acolisiswe kahle wesendlalelo ngasinye buhlukile. Ububanzi bebhendi ebanzi ye-crystalline ebanzi bungaphezu kuka-200μm, ububanzi bebhande elincane le-fine-crystalline bungu-10μm kuphela, futhi usayizi wokusanhlamvu ku-fine-crystalline band ungaphansi kuka-20μm. Kunokufakwa okuningi kweTi (C, N) ebhendini elinezinhlamvu ezinhle zebha yokuqala eyakhiwe, futhi iningi lazo lisemngceleni wokusanhlamvu. Umngcele wokusanhlamvu udlala indima yokuphina, futhi ngasikhathi sinye, kusenhlakeni nasekristal yebhande elinezinhlamvu ezinhle. Kunama-carbides amaningi emhlabeni. Ngoba i-Ti (C, N) nezinhlayiya ze-carbide zinomthelela omkhulu wokuphina ekuhambeni kokuhlukaniswa, zivimbela ukukhula kwamabele we-crystal, okuholela ekwakhiweni kwamabhande we-crystal amahle. Isakhiwo esijwayelekile sebha yokuqala eyakhiwe (ngaphandle kwendawo enhle yokusanhlamvu) inenqwaba yezulu eliqhubekayo noma eliqhubekayo le-carbide emngceleni wezinhlamvu, futhi ngokuyisisekelo akukho mvula enjenge-carbide okusanhlamvu, futhi akukho umngcele we-intragranular nokusanhlamvu. Kutholakale inani elikhulu lezinhlayiya ze-Ti (C, N).

Ngemuva kokuthi ibha yomgunyathi iphathwe ukushisa ngo-950 ℃ nge-2h, ibhendi elinezinhlamvu ezinhle selithuthukisiwe, kepha alicaci ngokusobala, futhi kusenamabhande amaningi amise okwenziwe ngebhande. Ngemuva kokwelashwa kokushisa ngo-1200 ° C, ukwakheka kwebha yomgunyathi kuyisixazululo esiqinile, kepha isakhiwo sebhande esinezinhlamvu ezinhle asikwazi ukususwa ngokuphelele.

Ukuhlolwa okwengeziwe kutholile ukuthi kusenamabhande we-crystal amahle kusakhiwo se-longitudinal sethubhu eliphakathi elihlanganisiwe, futhi amabhande we-crystal amahle akhiwe ngochungechunge lwezinhlamvu ezi-crystal ezilodwa. Amabhande we-crystal amahle asele weshubhu eliphakathi elihlanganisiwe lizoba nomthelela othile ekufaneni kwesakhiwo sesiphetho esiphelile. Ama-carbides emikhawulweni ye-longitudinal yokusanhlamvu yeshubhu eliqediwe esifundeni se-TT konke kusatshalaliswa ngokuqhubekayo noma okuqhubekayo, futhi amabhande emvula e-carbide atholakala esakhiweni. Ama-carbide precipitation bands asatshalaliswa isikhathi eside, futhi ukuqondiswa kwe-deformation rolling kuyefana. Ukuhlaziywa:

• (1) Izulu elingalingani lama-carbide ku-690 alloy bar forged isizathu esiyinhloko sokuba khona kwamabhande we-crystal amahle emabhaweni wokukhohlisa.
• (2) Ukuba khona kwamabhande akhiwe kahle ku-bar engu-690 yomgunyathi kuzokuthikameza ukufana kwethubhu le-690 alloy ngesikhathi sokucutshungulwa okwalandela, okuholele ekunciphiseni kwezulu le-carbide esakhiweni esiphelile sethubhu yokudlulisa ukushisa, futhi ekugcineni kuholele ekutheni isakhiwo sendawo se-tube esiphelile asilingani.
• (3) Ukuze kuqinisekiswe ukufana kwesakhiwo sethubhu yokudlulisa ukushisa kwe-alloy eqediwe engu-690, isakhiwo sebha yomgunyathi kufanele silawulwe ukugwema ukuba khona kwamabhande acwecwe kahle kubha.
