Indandatho yensimbi yangokwezifiso
I-cast iron iyingxubevange ehlanganisa ikakhulukazi i-iron, i-carbon, ne-silicon.
Kulawa ma-alloys, okuqukethwe kwekhabhoni kudlula inani elingagcinwa kusixazululo esiqinile se-austenite kumazinga okushisa e-eutectic.
I-cast iron ingxubevange ye-iron-carbon enokuqukethwe kwekhabhoni okukhulu kuno-2.11% (ngokuvamile u-2.5 ~ 4%).Iyingxube ye-multi-element enensimbi, ikhabhoni ne-silicon njengezakhi eziyinhloko futhi iqukethe i-manganese, isulfure, i-phosphorus eningi. kanye nokunye ukungcola kune-carbon steel.Ngezinye izikhathi ukuze kuthuthukiswe izakhiwo zemishini yensimbi ekhonjiwe noma ngokomzimba, izakhiwo zamakhemikhali, kodwa futhi wengeze inani elithile lezakhi ze-alloy, i-alloy cast iron.
Kusukela ekuqaleni kwekhulu lesithupha leminyaka BC, iShayina isiqalile ukusebenzisa insimbi ekhonjiwe, kunamazwe aseYurophu cishe eminyakeni eyizinkulungwane ezimbili ngaphambili.Insimbi yokusakazwa isengenye yezinto ezibaluleke kakhulu ekukhiqizeni izimboni.
Ngokohlobo lwekhabhoni ekhona ensimbini eyinsimbi, insimbi ekhonjiwe ingahlukaniswa ibe
1.Insimbi ewugqinsi emhlophe ngaphandle kwezimbalwa ezincibilikayo ku-ferrite, enye ingxenye yekhabhoni esesimweni sikasimende ikhona kunsimbi ekhonjiwe, ukuphuka kwayo kumhlophe okusiliva, okubizwa kanjalo ngensimbi ewugqinsi. yokwenza insimbi kanye nokungenalutho ukuze kukhiqizwe insimbi ethambile ethambile.
2.I-Gray cast iron carbon yonke noma iningi le-flake graphite likhona ensimbi ekhonjiwe, ukuphuka kwayo kuba mpunga obumnyama, okubizwa kanjalo nge-grey cast iron.
3.Ingxenye yekhabhoni ye-hemp cast iron ikhona ngendlela yegraphite, efana ne-grey cast iron.Enye ingxenye isesimweni sikasimende samahhala esifana ne-white cast iron.Umgodi omnyama nomhlophe ekuqhekekeni, ebizwa kanjalo nge-hemp cast iron.Lolu hlobo lwe-cast iron nalo lunobulukhuni obukhulu kanye nokuqina, ngakho aluvamile ukusetshenziswa embonini.
2Ngokusho kwe-graphite morphology ehlukene yensimbi ecijile, insimbi eyinsimbi ingahlukaniswa ibe
1.I-graphite esensimbini empunga iyi-flake.
2.I-graphite esensimbini ethambile ethambile i-flocculent.Itholakala ensimbini ethile emhlophe ewugqinsi ngemva kokuhushulwa emazingeni okushisa aphakeme isikhathi eside.Izici zayo zomshini (ikakhulukazi ukuqina kanye nepulasitiki) ziphakeme kune-grey cast iron, ngakho-ke ivame ukubizwa ngokuthi. insimbi ethambile ethambile.
3.I-graphite yensimbi eyi-nodular cast iyindilinga.Itholakala ngokwelashwa kwe-spheroidizing ngaphambi kokuthela insimbi encibilikisiwe.Lolu hlobo lwensimbi encibilikisiwe alunayo nje impahla ephakeme yemishini kune-grey cast iron kanye nensimbi ethambile ethambile, kodwa futhi inenqubo yokukhiqiza elula kune insimbi ethambile ethambile.Ngaphezu kwalokho, izakhiwo zayo zemishini zingathuthukiswa ngokuqhubekayo ngokusebenzisa ukwelashwa kokushisa, ngakho-ke kuyasetshenziswa kabanzi ekukhiqizeni.

Izembozo zomgodi
isethulo somkhiqizo:
Ukuqina okuhle.Inani lomthelela lifana nelensimbi ye-carbon steel, izikhathi ezingaphezu kweziyi-10 zensimbi empunga.
Ukumelana nokugqwala okuqinile.Esivivinyweni sokugqwala kwesifutho samanzi, inani lokugqwala ezinsukwini ezingama-90 liyi-1/40 kuphela lepayipi lensimbi kanye ne-1/10 yaleyo yepayipi lensimbi empunga. Impilo yesevisi izikhathi ezi-2 zepayipi lensimbi empunga kanye nezi-5 izikhathi zepayipi elivamile lensimbi.
Ipulasitiki enhle.Ukwelulwa ≥7%, kufana nensimbi ye-carbon ephezulu, kodwa ukwelulwa kwensimbi empunga kunguziro.
Amandla aphezulu.Amandla e-tensile ob ≥420MPa namandla okukhiqiza i-OS ≥300MPa ayafana nensimbi ye-carbon ephansi futhi kathathu njengensimbi empunga.
Ngenxa ye-nodular graphite microstructure, i-ductile iron ingcono kune-cast steel ekunciphiseni umthamo wokudlidliza, ngakho-ke kunenzuzo kakhulu ukunciphisa ukucindezeleka.Isizathu esibalulekile sokukhetha i-ductile iron ukuthi i-ductile iron ibiza kancane kune-cast steel.Izindleko eziphansi ze-ductile insimbi yenza le nto idume kakhulu, isebenze kahle, futhi ingabizi kakhulu emshinini.
Amandla ensimbi ene-ductile afana nalawo ensimbi ecijile.I-Ductile iron inamandla okukhiqiza aphezulu, inamandla amancane okukhiqiza angu-40K kanye namandla okukhiqiza ensimbi angama-36K kuphela. izicelo zikamasipala eziningi ezifana namanzi, amanzi anosawoti, isitimu, njll.

Ama-grates angokwezifiso
isethulo somkhiqizo:
Ama-Grizzley grate ayiqembu lama-cast-iron grates asetshenziselwa ukumboza ama-grates, imigodi, nezinye izigaxa ezivikelayo ezivikela ukuphepha komuntu noma ezivikela izihlahla nezinye izakhi zokuzivikela emonakalweni.
I-gratings i-gratings yemvula, i-gratings yesihlahla, i-grate gratings, i-floor gratings, njll.Ngokwesibonelo, izinsimbi zensimbi zivame ukufakwa emithonjeni yezindlu zokugeza, okuvumela amanzi ukuba ageleze futhi avimbele ukulimala kwezinyawo nezinyawo.

I-resin ihlanganisa
isethulo somkhiqizo:
1. Ukusebenza okuqinile kokulwa nobugebengu: isembozo somgodi we-resin esiyinhlanganisela ye-resin sisebenzisa i-resin engagcwele, i-fiber yengilazi nezinye izinto kanye nohlaka lwamathambo aqinisiwe ahlanganiswe inqubo ekhethekile yokukhiqiza, ngemuva kwezinga lokushisa eliphezulu nokucindezela ukwakha, inani lokubuyisela kabusha impahla, kunzima kakhulu khipha ibha yensimbi (khipha inani lensimbi ebiza ngaphezu kwensimbi) ngakho iwumsebenzi osebenzayo wokulwa nobugebengu.
2. Umthamo omkhulu wokuthwala: indawo ephansi yesakhiwo esingaphansi kwebhodwe elikhethekile, ukuze indawo ecindezelekile ikhule izikhathi eziyishumi noma ngisho namashumi amaningi. ukuze umkhiqizo ube nomthamo owanele wokuthwala.Futhi uhlangabezane noma weqe amazinga kazwelonke.
3. Impilo ende yesevisi, ngokwamukelwa kwe-resin yokusebenza ephezulu, i-glass fibre kanye nefomula ekhethekile, inqubo yokukhiqiza yokuqinisekisa ukuthi ukungena kwama-resin ku-fiber yengilazi, kuthuthukisa kakhulu ukudluliswa kwenduku, kwenza izinto zibe ngaphansi kokulayisha okujikelezayo, azikhiqizi ngaphakathi. umonakalo, ukuze kuqinisekiswe impilo yesevisi yomkhiqizo, kanye nezinye izembozo zomgodi wenhlaka eziyinhlanganisela ezinezinzuzo ezifanayo.Ukuqeda ukushiyeka kokunamathela okungekuhle.
4. Lihle futhi liyasebenziseka, izinga eliphezulu: Ngokwezidingo zamakhasimende aphezulu, singenza i-LOGO eyinkimbinkimbi nemibala ehlukahlukene endaweni yesembozo somgodi ofanayo womklamo womuntu siqu, ukuze iphethini ibe buthakathaka, imibala ekhanyayo, distinct.Futhi kungenziwa ngokuvumelana nesidingo samakhasimende kanye nazo zonke izinhlobo zokugandaya kwamatshe indawo efanayo yokulingisa kanye nombala.
5. Ukumelana nokushisa okuphezulu / okuphansi, ukufakwa okuhle nokumelana nokugqwala okuqinile: ukumelana nokugqwala, okungeyona ubuthi futhi okungenabungozi.Azikho izithasiselo zensimbi, ezidlale umuzwa wangempela womphumela wokufakelwa.Ingasetshenziswa ezindaweni eziyinkimbinkimbi, eziguquguqukayo, ezinzima nezifunayo. Imikhiqizo ihlolwe yizikhungo zokuhlola ezigunyaziwe zikazwelonke ezifanele, ezinokumelana okusobala kwe-asidi ne-alkali, ukumelana nokugqwala, ukulwa nokuguga nezinye izinkomba zifinyelele futhi zedlula izindinganiso zikazwelonke.
6. Ukuvikelwa kwemvelo, i-anti-skid, umsindo ophansi: umkhiqizo ngeke ushelele, akukho msindo onzima kanye nesenzakalo esibuyela emuva ngemva kokuba imoto igijinywe. Ngesikhathi esifanayo, ngenxa yesisindo esilula somkhiqizo, ikhava, ukunemba kwebhande lesihlalo. , nqoba enye ikhava yokuhlola "gxuma, stilt, sound, displacement" nezinye izinkinga.
