Izici Zensimbi YaseFerritic Engagqwali

1 Ukumelana nokugqwala kwesibhakabhaka kwensimbi engagqwali ye-ferritic

Njengoba insimbi engagqwali ye-ferritic inokumelana okuhle nokugqwala komkhathi, isetshenziswe njengophahla namakhethini odonga lwezakhiwo muva nje. Kodwa-ke, indawo esemkhathini ezindaweni ezisondele olwandle inzima kakhulu, ikakhulukazi izinhlayiya ezimisiwe olwandle nasemoyeni ziyizinto ezonakalisayo. Ngakho-ke, insimbi engagqwali ene-high-chromium ferritic esetshenziswa kulezi zindawo yenziwe. Insimbi engagqwali emelana nokugqwala komkhathi iqukethe i-chromium ephezulu ne-molybdenum ephezulu, futhi kufakwa inani elincane le-niobium ne-titanium. Le nsimbi empeleni iqukethe i-chromium engu-22% no-1.2% molybdenum. I-chromium eyanele ne-molybdenum kubalulekile ukwenza ngcono ukumelana kokungena ngensimbi engagqwali. Thayipha insimbi engagqwali yohlobo lwe-304 kanye ne-316 inokwenyuka okuphawulekayo endaweni yokugqwala ngokunyuka kwenani lemijikelezo yokuhlolwa kokugqwala kwe-cyclic. Ngokuphambene nalokho, ngezinsimbi ezingenazinsimbi ze-ferritic ezifana nohlobo lwama-444 nensimbi ye-R & D, indawo egqwalile yanda kancane phakathi nemijikelezo yokuqala yokuhlola engama-600, kwathi ngemuva komjikelezo wokuhlola omude, indawo egqwalile yayisesimweni esigcwele. Ibanga lensimbi elithuthukisiwe (22Cr-1.2Mo-Nb, Ti) likhombisa ukuthi indawo yokugqwala incane kunanoma yisiphi isikhathi sokuhlola.

2 Intergranular ukugqwala ukumelana insimbi engagqwali ferritic

Insimbi engagqwali i-410L noma i-409 isetshenziswa njengempahla yohlelo lokulawula ukukhishwa kwemoto ngenxa yokuphikisana kwayo nokugqwala, ukuqina nokuqina kokushisa. Eminyakeni yamuva nje, izinga lokushisa lokuklama lokuqhuma kwezimoto lenyukile. Lokhu kungenxa yokuthi ukwanda kwamazinga okushisa emoto kungathuthukisa ukusebenza kahle kokuguqula okuguqula futhi kunciphise amagesi ayingozi afana ne-NOx, SOx, ne-hydrocarbon (HC). Kodwa-ke, ukwanda kwezinga lokushisa kungaholela ezimweni zokugqwala ezimbi kakhulu. Isibonelo, i-chromium carbide izokhiqiza idiphozi kokushisa kokushisa, okungukuthi, ekushiseni okungu-400 kuye ku-500 ° C, kuzodala ukwehla kwe-chromium emngceleni wokusanhlamvu nokugqwala kwangaphakathi. Njengoba indawo ye-weld izwela kakhulu ukugqwala kwangaphakathi, kuyadingeka ukwenza ngcono ukumelana nokugqwala kwensimbi engenasici ye-ferritic equkethe i-12% Cr. Enye indlela yokuxazulula le nkinga ukwakha izinsimbi ezintsha ezingenazinsimbi ze-ferritic. Isibonelo esisodwa ukwengezwa kwe-niobium ensimbi equkethe i-12% Cr. Lezi zinsimbi zisetshenziswa kakhulu njengezinto zokumelana nokugqwala ezikhathini ezithile ezinhlelweni zokukhishwa kwemoto, njengamapayipi angaphambili, amapayipi aphakathi nendawo nezimbumbulu. Kuyaziwa ukuthi ukunciphisa okuqukethwe yikhabhoni ne-nitrogen ensimbi kuyasebenza impela ekuvimbeleni ukugqwala kwangaphakathi. Ngale ndlela, ukwengeza i-niobium ne-titanium ensimbi kungathuthukisa ukumelana kwayo nokugqwala kwangaphakathi.

3 Ukuqina kwensimbi engagqwali ye-ferrite

Ukusetshenziswa kwensimbi engenasici ye-ferritic kubanzi kakhulu, futhi izakhiwo zensimbi engenasici ye-ferritic edingwa ukusetshenziswa ngakunye kwehlukile. Kodwa-ke, ukuhleleka kwensimbi engagqwali ye-ferritic kubi kakhulu kunokwenziwe ngensimbi engagqwali ye-austenitic enjenge-304 steel. Yize inani le-γ lensimbi elingenasici le-ferritic, okungukuthi, inkomba yokudonsa ejulile, iyahlukahluka ku-1.0 kuya ku-2.0, inani le-n, okungukuthi, inkomba ye-ductility ilinganiselwe, cishe u-0.2, ongaphansi kuka-0.4 kuya ku 0.65 yensimbi engagqwali ye-austenitic. Ngemikhiqizo edwetshiwe, kunzima ukusebenzisa insimbi engenansimbi ye-ferritic ukufaka insimbi engagqwali ye-austenitic. Uma ufuna ukufaka esikhundleni sayo, kufanele ushintshe ukwakheka komkhiqizo bese uwuklama ube sesimweni esidwetshiwe.

4 Ukuqina kwensimbi engagqwali ye-ferritic

Izifundo eziningi zenziwe ngomphumela we-titanium ne-niobium ekwenziweni kwabezindaba, futhi kugxilwe kakhulu enanini eliphakathi nendawo. Isiphetho ngukuthi inani elifanele lalezi zinto lingathuthukisa ngempumelelo ukwakheka kwabezindaba. Kodwa-ke, ukwengezwa ngokweqile kwalezi zinto nakho kungaba nemiphumela emibi. Isibonelo, njengoba okuqukethwe kwe-titanium ne-niobium kukhuphuka, izinga lokushisa lokuguquka kwemifantu ye-longitudinal nayo iyanda. Noma insimbi engenansimbi ye-ferritic inenani elihle le-gamma, izinga lokushisa lokuguquguquka kwe-ductile lingadala umonakalo ekutholakaleni okujulile. Njengoba izinga lokushisa lenguquko lingesinye sezici ezinqumayo zokwenza izinto, ukuguquguquka kungaba nzima ukuqhubeka nezinga lokushisa eliphakeme lokuguqulwa.

5 Amandla okushisa aphezulu wensimbi engagqwali ye-ferritic

Insimbi engagqwali i-409L (11Cr-Ti) isetshenziswa njengezinto eziningi zemoto, futhi izinga lokushisa qeda lenzelwe ukuba libe ngama-800 ℃. Lapho izinga lokushisa likhipha cishe i-900 ° C, i-430J1L (18Cr-0.4Nb-0.5Cu) kusetshenziswa insimbi engagqwali. Kodwa-ke, izinga lokushisa qeda lisakhula, elidinga ukwenziwa ngcono kwekhwalithi yensimbi engagqwali. Ngale ndlela, ukumelana nokushisa kwensimbi engagqwali yendabuko ephezulu-chromium ferritic akukwazi ukuhlangabezana nezidingo zokuqothula okuningi. Ngakho-ke, bekulokhu kunesidingo esinamandla sezinsimbi ezingenantambo zokushisa okushisa okungabizi kakhulu. Uma ucabanga ngalesi sidingo, kufundiwe umphumela wokungeza i-niobium ne-molybdenum ekusebenzeni okushisa okuphezulu.
