Uhla olubanzi lwezinhlelo zokusebenza
Ngezakhiwo zayo ezinhle kakhulu zomzimba kanye nezinzuzo ezibalulekile zezomnotho,i-ductile ironkancane kancane iba yizinto ezikhethwayo emikhakheni eminingi yezimboni, ishintsha kabanzi izinto zendabuko njengensimbi engumgunyathi, insimbi enesitembu, izinto zokushisela, insimbi ethambile ethambile,insimbi empungakanye nensimbi. E-United States, lokhu kuthambekela kusobala ngokukhethekile. I-Ductile iron ibambe iqhaza elibalulekile emakethe futhi ishintshe ngempumelelo izilinganiso ezihlukene zezinto ezibalwe ngenhla, okubonisa amandla ayo okusebenza angenakuqhathaniswa kanye nokuncintisana kwemakethe.
| Izinkambu Zohlelo | Ukusakaza Okujwayelekile ku-Ductile Iron | Izimpawu Zokusebenza | Ibanga |
| Amapayipi amanzi, igesi kanye nowoyela | Amapayipi nokufakwa kwangaphakathi, anobubanzi obungaphansi noma obulingana no-2600 mm. | Ukumelana nengcindezi, ukumelana nokugqwala, ukumelana nokuzamazama komhlaba nokumelana nenhlabathi | |
| Izimoto, ogandaganda | I-Crankshaft, i-camshaft, induku yokuxhuma, igiya, izindlu ze-ekseli zokushayela, ubakaki we-balance shaft, izindlu ezihlukile, njll. | Ingagugi, imelana nokukhathala, amandla aphezulu kanye nokuqina, ikwazi ukumelana nemithwalo enomthelela ku -40°C | QT900-2 QT800-2 QT700-2 QT600-3 QT400-8 QT450-10 |
| Imikhumbi, izitimela, izinjini zikadizili | I-Crankshaft, induku yokuxhuma, i-camshaft, igiya, i-cylinder liner | Ukumelana nokugqoka, ukumelana nokukhathala, amandla aphezulu | QT900-2 QT800-2 QT700-2 QT600-3 |
| Imishini yezolimo | Izigxobo zokulima eziqhutshwa ngomshini, izinsimbi ezishayelwa umshini, amakhava eshaft, izivuni, ama-blade guards, amagiya | Ukuqina okuphezulu, ukumelana nomthwalo womthelela | I-QT400-15 QT450-10 QT500-7 |
| izingxenye Hydraulic | Umzimba we-valve, umzimba wepompo | Imelana nomfutho kawoyela futhi imelana nokugqoka | I-QT400-15 QT450-10 |
| Ukuphakamisa ukuthutha | Amagiya, ama-shafts, amasondo e-crane | Ingagugi, amandla aphezulu | QT900-2 QT800-2 QT700-2 QT600-3 |
Ukuhlaziywa kokwakheka kokukhiqiza
Ngokombono wesakhiwo sokukhiqiza, ukukhiqizwa kwe-iron ductile kubuswa i-matrix ye-ferrite, ibalwa ku-60% wesamba esiphumayo, kuyilapho i-pearlite matrix ilandela eduze ngemuva futhi ithatha indawo. Ngaphezu kwalokho, i-matrix exubile ye-ferrite ne-pearlite nayo ihlanganisa ingxenye enkulu. Lezi zintathu zihlangene zenza cishe u-95% wawo wonke ukukhiqizwa kwe-iron ductile, okugqamisa isikhundla esiphezulu sala matrices amabili ekukhiqizeni i-ductile iron.
Ukuhlaziywa kwezakhiwo zemishini ezinhle kakhulu
Isizathu esiyinhloko sokuthi kungani i-ductile iron ingagqama phakathi kwezinto eziningi sisezicini zayo eziyingqayizivele. Ayinalo iphuzu lokukhiqiza ngomqondo ovamile, futhi ijika le-stress-strain libonisa izici zegradient eziqhubekayo ngaphezu komkhawulo wokulinganisa. Lesi sici sisuka ekuziphatheni okuyingqayizivele kwamabhola e-graphite ngaphansi kokucindezeleka: lapho ukucindezeleka kudlula umkhawulo wokunwebeka, nakuba amabhola e-graphite abonakala eyingxenye ye-matrix, empeleni awasaguquki, enza izikhala kusiqondiso se-longitudinal, okuholela ekwandiseni ivolumu. , futhi lokhu kwandiswa akukwazi Ukunxeshezelwa ngokuminyanisa kwezinhlangothi.
Ukuqhathaniswa kokusebenza nezinye izinto
Insimbi empunga: Ngokwesiko, amandla aqinile kuphela asetshenziswa njengenkomba yokusebenza, futhi ibanga eliphakeme kakhulu linamandla okubamba alinganiselwe (ama-MPa angama-350 kuphela). Ngokuphambene, i-ductile iron ikhombisa izinzuzo ezibalulekile kuwo womabili amandla kanye nepulasitiki.
I-cast cast iron ephathekayo: Nakuba inezinkomba ze-plasticity, kungakhathaliseki ukuthi iyi-black-core, pearlite noma i-white-core ironableable iron, izici zayo ezibanzi zomshini azikho kahle njenge-ductile iron.
Insimbi ye-Cast ne-structural steel: Nakuba inokusebenza okuhle kakhulu ekwelulweni kwangemuva kokuphuka kanye nokuqina komthelela, amandla okukhiqiza awami kahle njengalawo e-iron edonsa amanzi, egqamisa futhi ukuphakama kwe-iron edonsayo ezinhlelweni ezithile.
