Ukusebenza Kokushisa Okuphezulu
Ibha yensimbi ye-alloy ye-F91 / P91 ibaluleke kakhulu ngenxa yamandla okuqhekeka, ukumelana nokushiswa kwe-oxidation kanye nokuqina kwesakhiwo se-microstructure sesikhathi eside ekusetshenzisweni kokushisa okuphezulu. Umklamo wayo we-alloy we-9Cr-1Mo-V-Nb uwenza ufaneleke kakhulu ezitshalweni zamandla ezidinga amandla kanye nemishini yokucindezela.
Umshini
Ibha eyindilinga ye-P91 / F91 ingasikwa, ijikwe, ibholwe, ibhobozwe, igaywe futhi igaywe ngokwezidingo zokudweba. Ngenxa yokuqukethwe kwe-alloy kanye nesimo sokulungiswa kokushisa, kunconywa amathuluzi okusika afanele, ukusetha okuqinile kanye nemingcele yomshini olawulwayo.
Ukushisela
Ukushisela izingxenye ze-F91 / P91 kudinga izinqubo zokushisela ezifanele, ukushisa okulawulwayo kwangaphambili, izinga lokushisa elilawulwayo le-interpass kanye nokwelashwa okufanele kokushisa ngemva kokushisela. Ukufaneleka kwenqubo yokushisela kanye nokulawula ubulukhuni kubalulekile ekuthembekeni kwenkonzo yokushisa okuphezulu.
Ukwelashwa Kokushisa
Ibha ye-F91 / P91 ngokuvamile inikezwa esimweni esijwayelekile nesifudumele noma ngokwemigomo elawulayo. Ukwelashwa kokushisa okungalungile kungathinta amandla, ubulukhuni kanye nokusebenza kokugoba, ngakho-ke ikhodi efanele kanye nesidingo sephrojekthi kufanele kulandelwe.
