Khulupirirani kuti abwenzi ambiri onse anagula mpeni khitchini kapena kuona mpeni khitchini, koma kupanga khitchini mpeni zitsulo adzakhala osokonezeka, nkhaniyi ndi zabwino?
Kodi ichi ndi chiyani?
Ndi chitsulo chosapanga dzimbiri?
Kapena chitsulo?
Osadandaula, zopangira zing'onozing'ono zanu zimakubweretserani 3 cr13 zitsulo, kutsatira komanso zinthu zina zouma.
3 cr13 chitsulo chosapanga dzimbiri, muyezo wachitsulo: GB/T1220 -
1992, a martensitic mtundu zitsulo zosapanga dzimbiri, zitsulo makina processing ntchito bwino, kutentha mankhwala (
Kuchepetsa mphamvu)
, ili ndi kukana kwa dzimbiri komanso kupukuta kwamphamvu kwambiri komanso kukana kuvala, koyenera kupanga pansi pa katundu wambiri, kukana kuvala kwakukulu ndi sing'anga ya dzimbiri pansi pa nkhungu ya pulasitiki.
Pambuyo kutentha mankhwala kuuma pansi HRC30 3 cr13 workability zinthu zabwino, zosavuta kukwaniritsa bwino pamwamba.
Ndipo kuuma kuposa HRC30 magawo akukonza, ngakhale mawonekedwe apamwamba ndi abwino, koma chida ndi chosavuta kuvala.
Choncho, pambuyo zipangizo mu fakitale, choyamba conditioning mankhwala pa kuuma HRC25 ~ 30, kenako Machining.
Kuposa 2 cr13 mutatha kuzimitsa kuuma, chida chodulira, nozzle, mpando wa valve, valve, etc.
3 cr13 kachulukidwe ka 7.
75 g / cm3 yofanana ndi chizindikiro: 420 b ikugwirizana ndi mtundu wa Britain: 420 s45 yofanana ndi chizindikiro cha French: Z30C13Ps: martensitic zitsulo zosapanga dzimbiri, mphamvu zapamwamba koma pulasitiki yosauka komanso weldability.
Mtundu womwe umagwiritsidwa ntchito nthawi zambiri uli ndi 1 cr13 martensitic chitsulo chosapanga dzimbiri, 3 cr13, etc. Zofunikira pakugwira ntchito nthawi zambiri pazigawo zina, monga masika, masamba a turbine, ma hydraulic valves, ndi zina.
Chitsulo chamtunduwu chimagwiritsidwa ntchito pambuyo pozimitsa ndi kutentha. Pamafunika annealing pambuyo forging, chidindo.
