12Cr1MoV letlapa la tšepe le chesang

12Cr1MoV tšepe e chitja e na le khanyetso e phahameng ea oxidation le matla a mocheso. Moeli oa creep oa tšepe ena o haufi haholo le boleng ba matla a mamello, 'me o na le polasetiki e phahameng tabeng ea tsitsipano e sa feleng; tšepe e na le manufacturability e ntle le weldability, empa e hloka ho futhumatsoa pele ho 300 ° C pele ho tjheseletsa le ho imolla khatello ea kelello ka mor'a ho cheselletsa. sebetsana le. Ke boemo ba tšepe bo sebelisoang haholo khatellong e phahameng, khatello e phahameng haholo, li-superheaters tsa li-boiler tsa subcritical power station, lihlooho le li-ducts tse kholo tsa mouoane. E ntse e na le matla a phahameng a mocheso le khanyetso ea oxidation ho 580 ° C, 'me poleiti ea tšepe ea 12Cr1MoV e na le polasetiki e tšoarellang e phahameng. Ts'ebetso ea tlhahiso e batla e le bonolo, mme ts'ebetso ea welding e ntle, empa e na le kutloelo-bohloko ho sekhahla sa ho pholisa se tloaelehileng. Tšebeliso ea nako e telele ho 580 ° C e tla hlahisa pearlite spheroidization.
