Iyini insimbi engagqwali ye-austenitic?

Iyini insimbi engagqwali ye-austenitic? Yiziphi izingxenye zensimbi engagqwali ye-austenitic? Yiziphi izici ze-austenitic stainless steel? Yiziphi izinhlelo zokusebenza ze-austenitic stainless steel? Kulesi sihloko, sizophendula le mibuzo ngokuningiliziwe.

Iyini insimbi engagqwali ye-austenitic?

Kuwuhlobo olukhethekile lwe-stainless ingxubevange yensimbi. Ibonakala ngokuqukethwe okuphezulu kwe-chromium ne-nickel. Insimbi ye-Austenitic ayinamagnetic futhi inezakhiwo ezinhle kakhulu zokushisela nokuzenzela.

Yiziphi izingxenye zensimbi engagqwali ye-austenitic?

Ingxubevange ye-chromium-nickel equkethe cishe u-18% we-chromium no-8% we-nickel. Azinazibuthe futhi zinokumelana nokugqwala okuphezulu kunezinye izinhlobo zensimbi engagqwali. Insimbi engagqwali ye-Austenitic nayo mancane amathuba okuthi ibe brittle emazingeni okushisa aphansi.

Yiziphi izici ze-austenitic stainless steel?

Kuwuhlobo olukhethekile lwengxube yensimbi engagqwali enokuqukethwe okuphezulu kwe-chromium ne-nickel. Uma kuqhathaniswa nezinye izinhlobo zensimbi engagqwali, zinekhabhoni ephansi, ezinikeza ukumelana okuhle kakhulu nokugqwala kwe-intergranular. Insimbi ye-Austenitic nayo inokwakheka okuhle nokushisela.

Ezinye izici ezibalulekile zifaka:

• Ukumelana nokugqwala okuphezulu
• I-ductility ephezulu nokuqina
• Ukuqina okuhle nokuqina
• Ukusebenza okuhle kakhulu kwezinga lokushisa eliphansi

Yiziphi izinhlelo zokusebenza ze-austenitic stainless steel?

Iwuhlobo olusetshenziswa kakhulu lwensimbi engagqwali. Ziyingxubevange ye-chromium-nickel enokuqukethwe kwe-chromium kusuka ku-16% kuya ku-30% kanye nokuqukethwe kwe-nickel kufika ku-35%. Baziwa ngokumelana nokugqwala okuhle kakhulu kanye nezakhiwo ezinhle zemishini.

Ezinye izinhlelo zokusebenza ezijwayelekile zifaka:

• Imishini yokucubungula ukudla
• Osinki nezindawo zokusebenza
• Amathangi okugcina amakhemikhali
• Imikhumbi yokucindezela
• Izingxenye ze-Aerospace

Okuningi mayelana ne- izicelo ze-austenitic insimbi engagqwali:

I-Austenitic 304 insimbi engagqwali plate iwumsebenzi okusolwa ukuthi unikeza ukugqwala okuqinile nokumelana nokugqwala, ipulasitiki enhle kakhulu kanye nokuqina, futhi kulula ukuyigxiviza nokwenza. Ngokuminyana okungu-7.93 g/cm³, insimbi engagqwali engu-304 iwuhlobo oluvame kakhulu lwensimbi engagqwali, eyaziwa nangokuthi i-18/8 insimbi engagqwali embonini. Imikhiqizo yayo yensimbi ayikwazi ukumelana nokushisa futhi inezakhiwo ezinhle zokukhanda, okwenza isetshenziswe kabanzi ezimbonini ezifana nemboni yefenisha neyokuhlobisa, imboni yokudla nezokwelapha.

Inqubo yokukhiqiza ye-Austenitic Stainless Steel

Ukusebenza kwenqubo yokukhiqiza ye-austenitic insimbi engagqwali kuhle, ikakhulukazi ku-chromium-nickel austenitic steel stainless. Ukucaciswa okuhlukahlukene okuvame ukusetshenziswa kwepuleti, ishubhu, i-strip, intambo, isitoko sebha, ama-forging kanye nokulingisa kungakhiqizwa kahle kusetshenziswa izindlela ezijwayelekile zokukhiqiza insimbi ekhethekile.

Ngenxa yokuqukethwe okuphezulu kwezakhi ze-alloy (ikakhulukazi i-chromium) kanye nokuqukethwe kwekhabhoni ephansi, izinsimbi eziningi ze-austenitic ezingenasici zikhiqizwa ngobuningi kusetshenziswa i-arc furnace plus argon-oxygen decarburization (AOD) noma izindlela ze-vacuum oxygen decarburization (VOD). Emikhiqizweni yevolumu encane yezinga eliphezulu, ukuncibilikisa kwesithando se-vacuum noma okungeyona i-vacuum kungasetshenziswa, futhi ukuncibilika kwe-slag kagesi kungase kudingeke uma kunesidingo.

Izici ezinhle kakhulu ze-thermoplastic ze-chromium-nickel austenitic stainless steel zenza kube lula ukwenza ukucubungula okushisayo okufana nokufoja, ukugingqa, ukubhoboza okushisayo, nokukhipha. Izinga lokushisa lokushisisa lensimbi yensimbi liyi-1150-1260 ℃, futhi izinga lokushisa lokuguquguquka ngokuvamile liyi-900-1150 ℃. Amabanga ensimbi aqukethe ithusi, i-nitrogen, futhi azinzile nge-titanium ne-niobium avame ukuncika emazingeni okushisa aphansi, kuyilapho amazinga aphezulu e-chromium nensimbi ye-molybdenum evame ukuncika emazingeni okushisa aphezulu. Ngenxa ye-thermal conductivity engalungile, isikhathi sokufakelwa kufanele sibe side.

Ngemuva kokucubungula okushisayo, i-workpiece ingapholiswa emoyeni. I-Chromium manganese austenitic insimbi engagqwali inokuzwela okunamandla kokuqhekeka okushisayo. Lapho i-ingot yensimbi ivuliwe, ukuguqulwa okuncane kanye nokudlula okuningi kuyadingeka, futhi ama-forging kufanele apakishwe futhi apholiswe. Ingenza amasu okucubungula abandayo njengokugoqa okubandayo, ukudweba okubandayo, nokuphotha, kanye nokwenza imisebenzi efana nokunyathela, ukugoba, ukugoqa, nokugoqa.

Ukuthambekela kokuqina komsebenzi kwensimbi engagqwali ye-chromium-nickel austenitic ibuthakathaka kunaleyo yensimbi ye-chromium-manganese, futhi ukonakala okubandayo ngemva kokudonsa okukodwa kungafinyelela ku-70% kuya ku-90%. Kodwa-ke, ngenxa yokumelana nokuguquguquka okuphezulu kanye nokuthambekela kokuqina komsebenzi we-chromium manganese austenitic yensimbi engagqwali, inani lokuthambisa okuphakathi nendawo kufanele linyuswe. Ukwelashwa kokuthambisa okuphakathi nendawo okuthambisayo ukupholisa amanzi ku-1050-1100 ℃.

Insimbi engagqwali ye-Austenitic nayo ingasetshenziselwa ukukhiqiza ama-castings. Ukuze kuthuthukiswe ukugeleza koketshezi lwensimbi futhi kuthuthukiswe ukusebenza kokusakazwa, ukwakheka kwealloyi yensimbi yokulingisa kufanele kulungiswe: kwandiswe okuqukethwe kwe-silicon, kwandiswe ububanzi bokuqukethwe kwe-chromium ne-nickel, nokwandisa umkhawulo ongaphezulu wesici sokungcola okuqukethwe kwesibabule. .

Izinsimbi ezingenasici ze-Austenitic kufanele zibe ngaphansi kokwelashwa kwesixazululo ngaphambi kokusetshenziswa ukuze kwandiswe isisombululo esiqinile se-carbides nezinye izimvula ensimbi ku-matrix ye-austenite, kuyilapho futhi i-homogenizing isakhiwo futhi iqeda ingcindezi, ngaleyo ndlela iqinisekisa ukumelana nokugqwala okuhle kakhulu kanye nezakhiwo zemishini. Uhlelo olulungile lokwelapha isixazululo ukushisa ku-1050-1150℃ bese umanzisa epholile (izingxenye ezizacile nazo zingapholiswa ngomoya). Izinga lokushisa lokwelapha isixazululo lincike ezingeni le-alloying lensimbi: amamaki ensimbi aphansi-molybdenum noma aphansi-molybdenum kufanele abe ngaphansi (≤1100℃), kuyilapho amamaki ahlanganisiwe aphezulu njenge-00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, njll. kufanele abe ngaphezulu (1080) -1150 ℃).

Ubuchwepheshe obuthuthukisiwe busetshenziswa kakhulu ekukhiqizeni, njengezinga lokucwenga elingaphandle kwesithando elifinyelela ngaphezu kuka-95%, isilinganiso esiqhubekayo sokuphonsa esingaphezu kuka-80%, kanye nezigayo eziginqikayo ezinesivinini esikhulu, ukunemba, kanye nemishini yokukha esheshayo ekhuthazwa kabanzi. Ikakhulukazi, ukuqaliswa kokulawulwa kwekhompyutha ye-elekthronikhi ekuncibilikiseni nasekucutshungulweni kuqinisekisa ukuthembeka nokuzinza kwekhwalithi nokusebenza komkhiqizo.
