Iyini insimbi?
I-cast iron iyiqembu lama-alloys ensimbi ngokuvamile aqukethe phakathi kuka-2% no-4% wekhabhoni.Ngokuya ngohlobo lwensimbi ekhonjiwe, ingafinyelela ngisho nokufika ku-5%.Yakhiwa ngokuncibilikisa insimbi yensimbi noma insimbi yengulube bese ixutshwa nezinsimbi ezilahliwe ezihlukahlukene kanye namanye ama-alloys.Indwangu encibilikisiwe ibe isithelwa esikhunjeni, noma esibunjiwe.Iqina ibe yisimo sesikhunta ngaphandle kokuyekethisa amandla ayo.Okuqukethwe kwekhabhoni ephezulu kwe-cast iron kuyinikeza ukumelana namandla okugqokwa okuvelele.
Iyini insimbi ethambile ethambile?
I-cast cast iron ethambile idalwa ngokwelashwa kokushisa okungapheli kwe-cast iron.Le nqubo inciphisa okuqukethwe kwekhabhoni futhi ithuthukisa ukusebenza kanye ne-ductility.Ekuqaleni, insimbi emhlophe yensimbi - olunye uhlobo lwensimbi ekhonjiwe enokuqukethwe kwekhabhoni ephezulu - iphonswa.Bese ishiselwa ngaphansi nje kwendawo yayo yokuncibilika isikhathi eside, okwenza ikhabhoni iguquke ibe igraphite.Lokhu kubangela ukwakheka kwamaqhuqhuva noma ama-sphere, okudala insimbi exutshwe nethambile.Inqubo ye-annealing inciphisa ukuqina, ithuthukise ukumelana nokuqhekeka futhi ivumele ukugoba nokubunjwa ngaphandle kokuqhekeka.
Izakhiwo ze-Cast-iron
Yiziphi izici ze-cast iron?Lokho kuncike ohlotsheni lwensimbi ekhonjiwe, esiyibale ngezansi.Uma izinga lekhabhoni liphezulu, kulapho insimbi esakazwayo iba brittle, okuyenza ibe sengozini yokuqhekeka futhi iphuke ngaphansi kwengcindezi.Ngesisindo esishisayo esiphezulu, insimbi ekhonjiwe nayo inokugcina ukushisa okuhle kakhulu.
Uhlobo lwensimbi ekhonjiwe | Izakhiwo ze-cast iron |
Insimbi empunga | Amandla okuqina aphansi futhi hhayi njenge-ductile njengamanye ama-iron cast;ukumelana nokugqwala;i-brittle - kunzima ukudala indawo ebushelelezi;umqhubi omuhle kakhulu we-thermal kanye nezinga eliphezulu lokudambisa ukudlidliza. |
Insimbi emhlophe | Ayishiseli;amandla aphezulu okucindezela kanye nokumelana okuhle kokugqoka;izakhiwo ezinhle kakhulu zezinhlelo zokusebenza ezinomthelela ophansi. |
I-Ductile cast iron | I-nodular graphite ku-microstructure yayo ngokufaka i-magnesium, inikeza amandla aphezulu, ukuqina kanye ne-ductility kune-iron empunga. |
Insimbi ye-graphite ehlanganisiwe | Isakhiwo se-graphite, izakhiwo ezihlotshaniswayo ziyinhlanganisela ye-iron empunga nemhlophe, amandla aphakeme okuqina kanye ne-ductility ethuthukisiwe kune-iron empunga. |
Isetshenziselwani insimbi?
Ukusetshenziswa kwe-cast-iron kuncike ohlotsheni lwe-cast-iron.Uzobona ukugqagqana ngezansi.Siphinde safaka nokusetshenziswa kwensimbi ethambile ethambile.
Insimbi esetshenziswayo | Isetshenziselwa i-cast iron |
Insimbi empunga | Amapayipi, imizimba yama-valve, izingxenye zevalvu, izindlu zamathuluzi omshini, izigubhu zamabhuleki |
Insimbi emhlophe | Izinhlelo zokusebenza lapho kukhona ukungqubuzana okuslayidayo phakathi kwezindawo ezimbili, okungukuthi amapuleti okugqoka namalayini wemishini yezimayini, izixube zikasimende, izigayo zamabhola nokunye kokudweba okufayo namabhomu okukhipha |
I-Ductile cast iron | Amapayipi amanzi nendle, ugandaganda nezingxenye ezisetshenziswayo, ama-crankshafts ezimoto nawedizili, amapiston namakhanda amasilinda;izinto zikagesi, amabhokisi okushintsha, amafreyimu ezimoto & izingxenye ze-circuit breaker;impahla yezimayini: izigubhu zokuphakamisa, ama-pulleys okushayela, ama-flywheel namabhakede e-lifti;& Insimbi yokugaya: iminyango yesithando somlilo namaroli wetafula |
Insimbi ye-graphite ehlanganisiwe | Amabhulokhi enjini ye-diesel, izindlu ze-turbo, ama-nifold exhaust |
Insimbi ethambile ethambile | Isitimela sokushayela izimoto kanye nezingxenye ze-ekseli, okokusebenza kwezolimo nomzila wesitimela;futhi, amajoyinti okunweba kanye nokusakazwa kwezinsimbi kumabhuloho, ama-chain-hoist assemblies, ama-industrial casters, okokufakwa kwamapayipi, nezinduku zokuxhuma. |
I-cast iron vs ironableable
Izakhiwo ze-cast cast iron ezithambile zibandakanya ukusebenziseka okukhethekile, ukuqina kanye ne-ductility.Ikwazi ukumelana nokushaqeka, inekhono elihle kakhulu lokumelana namazinga aphezulu okucindezeleka.
Insimbi ethambileyo kulula ukusebenza ngayo kunezinsimbi ezisansimbi.Isibonelo, izinsimbi ezithambile ezithambile noma izifakelo zamapayipi ezithambile zingenzeka ngemiklamo eyinkimbinkimbi.Ivamise ukuba nephuzu lokuncibilika eliphakeme kunama-ayina acijile ku-1260°C - futhi, lokhu kuncike kuma-alloys ku-cast iron, njengenani lekhabhoni eliqukethe.Kodwa indawo yokuncibilika ye-cast iron ngokuvamile iyenza ikwazi ukuncibilika kangcono, ukuze ithulule kalula ezibunjeni ngaphandle kokupholisa ngokushesha.
Esinye isiqhathaniso: insimbi ethambileyo vs.Insimbi ethambileyo ayikwazi ukuhlukaniswa ukuze isuswe kalula, njengezinsimbi ezisansimbi.
Izinzuzo zensimbi ethambile ethambile
Kuwenza nini umqondo ukusetshenziswa kwensimbi ethambile ethambile?Uma udinga lezi zinzuzo:
I-Ductility - ilungele izinhlelo zokusebenza ezizodinga imishini ebanzi ngesikhathi sokuqeda.Uma iqhathaniswa ne-iron ductile, ayinalo izinga elifanayo lamandla aqinile, ukunwebeka kanye nokumelana nomthelela, kodwa isenza kalula ukwenza imishini ngaphandle kokuphuka.
Ingenziwa isicaba futhi yenziwe ngesando, uma kuqhathaniswa namanye ama-ayina acijile angaphuka noma aphuke.
- Icishe iqine njengensimbi empunga.
- Ukumelana nomthelela omuhle emazingeni okushisa aphansi kakhulu.
Ukungalungi kwensimbi ethambile ethambile
Izakhiwo ezingokoqobo ze-cast cast iron ezithambile zinezimo ezimbi, Ngaso sonke isikhathi qaphela ububi bento:
Iyashwabana lapho ipholile, njengoba ilahlekelwa umthamo.Zonke izinsimbi ezisansimbi - nanoma iyiphi into - zikwenza lokhu ngezinga elithile, kodwa kugqame kakhulu ngensimbi ethambile ethambile.
Ukumelana nokugqwala okuphansi.
Ayiqinile njenge-ductile cast iron noma insimbi.Ngezinhlelo zokusebenza ezidinga amandla aphezulu noma amandla acindezelayo, khetha enye insimbi ekhonjiwe.
Ingaphinda ibe brittle emazingeni okushisa aphezulu, ikwenze kube sengozini yokuqhekeka.
