Insimbi Engagqwali

Insimbi Engagqwali

I-Duplex Steel engenacala (i-DSS) isho insimbi engenacala nge-Ferrite ne-Accounting Accounting ecishe ibe ngu-50% ngayinye, futhi okuqukethwe kwesigaba esincane ngokuvamile kudinga ukufinyelela okungenani ama-30%. Endabeni yokuqukethwe okuphansi kwe-C, okuqukethwe kwe-CR kungu-18% ~ 28%, futhi okuqukethwe kwe-NI kungu-3% ~ 10%. Amanye amansimbi aqukethe izinto ezengeziwe ezinjengeMo, Cu, NB, TI, NO-N.
Insimbi Engagqwali inezici zokusebenza okulandelayo:
. Ngokuvamile, 18-8 Thayipha insimbi yensimbi engenasici ivame ukucindezela ukuqhekeka kokugqwala ezixazululweni ezingathathi hlangothi ngezixazululo ezingathathi hlangothi ngenhla kwama-60 ° C. Ukushisa ukushisa, ama-evaporators neminye imishini eyenziwe ngalolu hlobo lwensimbi engagqwali kuthambekele ekukhiqizeni ukugcwala kwe-chlorion kanye ne-hydrogen sulfide media, ngenkathi insimbi engabi nalutho inokuphikiswa okuhle.
. Lapho unenzuzo efanayo yokuphikisana (Pre = CR% + 3.3mo% + 16n% Ukuphikiswa kokugqwala okukhohlakele kwensimbi engenacala nensimbi engenacala ye-auntenitic kulingana ne kwe-Aisi 316l. Ukuphikiswa okukhohlisayo nokukhohlakala kwe-crovice kwensimbi ephezulu ye-chromium duplex nsimbi engenacala equkethe ama-25% Cr, ikakhulukazi i-nitrogen, idlula leyo ye-aisi 316l.
(3) Inokukhathala okuhle kokugqwala futhi igqoke ukumelana nokugqwala. Ngaphansi kwezimo ezithile zemidiya ezonakalisayo, ilungele ukwenza imishini yamandla kagesi njengamaphampu nama-valve.
(4) Inezakhiwo ezinhle kakhulu zemishini. Inamandla aphezulu kanye namandla okukhathala, namandla ayo okuvutha aphindwe kabili kwensimbi engu-18-8 autenitic. I-elongation esimweni esiqinile sokulungiselela ifinyelela ku-25%, futhi i-Fluenness Value AK (V-Notch) ingaphezulu kwe-100J.
(5) Inokuthambekela okuhle nokuthambekela okushisayo okushisayo. Ngokuvamile, akukho okudingekayo ngaphambi kokushiswa ngaphambi kokushiswa, futhi akukho ukwelashwa okushisa okudingekayo ngemuva kokufudumala. Ingafakwa ngezinto ezingekho emthethweni ezifana ne-18-8 i-auntenitic yensimbi engenacala noma ngensimbi yekhabhoni.
(6) Uhla lokushisa olushisayo lokushisa lwensimbi engagqwali equkethe i-chromium ephansi (18% Ingadonswa ngqo kwizigidigidi ukukhiqiza amapuleti ensimbi ngaphandle kokuthola. Ukusebenza okushisayo kwensimbi engenacala equkethe i-chromium ephezulu (25% CR) kunzima kancane kunaleyo yensimbi engenacala, futhi kungakhiqiza imikhiqizo efana namapuleti, amashubhu nezintambo.
. Esesigabeni sokuqala sokodonga kwamashubhu namapuleti, kudinga ukucindezelwa okukhulu ekulimaleni.
. Ilungele ukwenza umnyombo wabashisi bokushisa, futhi ukusebenza kwawo kokudluliselwa kokushisa kuphakeme kunalokho insimbi engagqwali ye-auntenitic.
. Ukwehlisa okuqukethwe kwe-chromium ngensimbi engenacala, okulimazayo okulimazayo kwezigaba ezinjenge-σ.
