12Cr1MoV ishidi lensimbi eligoqiwe elishisayo

Insimbi eyindilinga engu-12Cr1MoV inokumelana ne-oxidation ephakeme namandla ashisayo. Umkhawulo wokukhasa wale nsimbi usondelene kakhulu nenani lamandla okukhuthazela, futhi une-plasticity ephezulu uma kwenzeka ukungezwani okungapheli; insimbi inokwakheka okuhle nokushisela, kodwa idinga ukushiselwa ku-300 ° C ngaphambi kokushisela nokunciphisa ukucindezeleka ngemva kokushisela. ukubhekana. Kuyizinga lensimbi elisetshenziswa kakhulu ekucindezelweni okuphezulu, umfutho ophakeme kakhulu, ama-boiler superheaters wesiteshi samandla angaphansi, izihloko kanye namapayipi amakhulu esitimu. Isenamandla ashisayo aphezulu kanye nokumelana ne-oxidation ku-580°C, futhi ipuleti lensimbi elingu-12Cr1MoV linepulasitiki ehlala isikhathi eside. Inqubo yokukhiqiza ilula, futhi ukusebenza kokushisela kuhle, kodwa kuzwela kakhulu izinga lokupholisa elijwayelekile. Ukusetshenziswa isikhathi eside ku-580°C kuzokhiqiza i-pearlite spheroidization.

I-GB/T3077 12Cr1MoV ingxubevange yesakhiwo sensimbi yensimbi ibha isetshenziswa kakhulu kungcindezi ephezulu, umfutho ophezulu wegazi, i-subcritical power plant superheater, isethi ibhokisi njll. Ku-580 C, 12Cr1MoV insimbi yesakhiwo sengxubevange isenamandla ashisayo aphezulu kanye nezakhiwo zokulwa ne-antioxidant, futhi inazo. ipulasitiki ephezulu eqinile.
