I-Cast Iron vs. Steel: Yiziphi Izinzuzo kanye Nokubi Kwakho?

Kokubili insimbi nensimbi eyinsimbi yizinsimbi ezidumile, kodwa zivame ukusetshenziswa ngokuhluke kakhulu.Isici esiyinhloko esihlukanisa enye kwenye ukuthi ingakanani ikhabhoni ngayinye iqukethe, futhi ngezinga elincane, ingakanani i-silicon.Nakuba lokhu kungase kubonakale njengomehluko ocashile, kunemithelela emikhulu ezimpahleni nasekusetshenzisweni kwensimbi eyinsimbi nensimbi.
I-Cast Iron: Izinzuzo kanye nokusetshenziswa

Njengensimbi, insimbi eyinsimbi iyingxubevange yensimbi.Kodwa-ke, ukuze kubhekwe njengensimbi eyinsimbi, insimbi kufanele ibe ne-carbon content engu-2-4% kanye nokuqukethwe kwe-silicon engu-1-3% ngesisindo.Le chemistry inikezela ngensimbi ekhonjiwe ngenani lezinto eziwusizo:

I-cast iron ingaphinde ihlukaniswe ibe yi-iron empunga, i-iron emhlophe, i-ductile iron, nensimbi ethambile.Uhlobo ngalunye lugxile ekuthuthukiseni izakhiwo ezithile zohlelo oluthile, njengokuqina okuphezulu kwensimbi ekhonjiwe emhlophe.
Ukusetshenziswa kwe-iron cast kuyafinyeleleka kakhulu, kepha nazi izinhlelo zokusebenza ezimbalwa eziphawulekayo:

Amapani okuthosa okusansimbi nezinye izitsha zokupheka
Amabhulokhi enjini yezimoto, ama-brake disks, nezinye izingxenye eziningi
Amasango othango lokuhlala, izigxobo zokukhanya zokuhlobisa, izakhi zeziko, nezinye izinto
Amavalvu, okokufakwa, kanye nembobo yemigodi emanzini nasezimpompini zendle
Amaketango, amagiya, ama-shafts, ukuxhumana, nokunyeInsimbi: Izinzuzo kanye nokusetshenziswa
Insimbi: Izinzuzo kanye nokusetshenziswa

Ngokufanayo ne-iron cast, izinsimbi ziyi-alloys esekelwe ensimbi enezigaba ezimbalwa ezihlukene.Zonke izinsimbi zinekhabhoni ethile efinyelela kumkhawulo ka-2% ngesisindo futhi zingahlukaniswa zibe yinsimbi ye-carbon steel noma i-alloy steel.

Zingaphinde zihlukaniswe zibe izinsimbi ezinekhabhoni ephansi, izinsimbi ezingenasici, izinsimbi zamathuluzi, izinsimbi ezinama-microalloyed, nokunye.Yize lezi zinganikeza izinzuzo eziningi ezengeziwe, njengamandla aphezulu kanye nokumelana nokugqwala okuvela ezinsimbi ezingenasici, lesi sihloko sizogxila kuma-alloys ensimbi afana nalawo achazwe yi-ASTM A148.

Njengoba insimbi ekhonjiwe ibiza kakhulu kune-cast iron, izinzuzo zayo eziyinhloko kune-cast iron yilezi:

Amandla Aqinile - Ngokuya nge-alloy esetshenzisiwe, insimbi ekhonjiwe ingaba namandla aphezulu kakhulu okuqinile kune-cast iron.
Ukuqina/I-Ductility - Ngaphansi kokucindezeleka okukhulu, insimbi ingakhubaza (isikhashana noma unomphela) ngaphandle kokuphuka.Nakuba lokhu kungase kusho ukuqina okuncane kwezinye izinhlelo zokusebenza, kunciphisa amathuba okuqhekeka futhi kusho ukusebenza komthelela ongcono.
Ukushisela - Ngokuya nge-alloy esetshenzisiwe, insimbi inikeza ukushisela okuhle, kanti i-cast iron inselele ukuyishisela ngaphandle kokubangela ukuqhekeka.
Nakuba ukubumba, ukugingqika, kanye nokuphonsa konke kungenzeka emikhiqizweni yensimbi, ezinye izinhlelo zokusebenza ezibalulekile ezigxile ensimbini yilezi:

Amasondo emoto kaloliwe, ozimele, nama-bolster
Imishini yezimayini, izinto zokwakha, namaloli asindayo
Amaphampu omsebenzi osindayo, ama-valve, nezinsimbi
Ama-Turbocharger, amabhlogo enjini, nezinye izingxenye zezimoto
Ama-turbines nezinye izingxenye emibuthanweni yeziteshi zikagesi

Imikhiqizo yensimbi nensimbi eyenziwe ngomshini:
I-cast iron ngokuqinisekile ilula futhi ishibhile emshinini kunensimbi ecijile, kodwa amandla okusebenza ahluka kakhulu phakathi kwama-alloys.Ngakho-ke uma uklama umkhiqizo odinga ukusebenza kwemishini okude, kungase kudingeke ukuthi ubuyekeze ama-alloys atholakalayo ukuze uthole onekhono elingcono.

Kodwa noma ngabe ukhawulelwe ezintweni ezinzima kakhulu, isitolo semishini esinolwazi, esisezingeni lomhlaba singanciphisa isikhathi sokwenza imishini ukuze wonge ezindlekweni zokuwenza.Ake sinikeze izinsizakalo zemishini ezisheshayo, ezinokwethenjelwa zezinto ezihlukahlukene zenkampani yakho nezinhlobo zemikhiqizo.
