Insimbi engagqwali Casting, njengoba igama layo lisho, kuyinqubo yokukhipha ama-alloys ensimbi engagqwali. Ukukhishwa kwe-investimenti noma ukulahlekelwa kwe-wax cast, iyindlela enembe kakhulu yokwenza imikhiqizo yensimbi engagqwali, ikakhulukazi lezo zakhiwo ezingajwayelekile noma eziyinkimbinkimbi, ngakho-ke ukufakwa kwe-investimenti yensimbi engagqwali kucishe kulingane nokusakazwa kwensimbi engagqwali ngokunemba.
Ukukhishwa kwe-investimenti noma ukulahlekelwa kwe-wax cast, iyindlela enembe kakhulu yokwenza imikhiqizo yensimbi engagqwali, ikakhulukazi lezo zakhiwo ezingajwayelekile noma eziyinkimbinkimbi, ngakho-ke ukufakwa kwe-investimenti yensimbi engagqwali kucishe kulingane nokusakazwa kwensimbi engagqwali ngokunemba. Yonke inqubo yokukhipha insimbi engagqwali iqukethe izinyathelo ezimbalwa: ukwenza isikhunta, ukwenza imodeli ye-wax, umhlangano wesihlahla, ukucwilisa kanye nokucwilisa, ukuthela, njll.
Yiziphi izinto ezisetshenziswa ekutshalweni kwezimali?
Injini yokuklama kuqala yenza iphethini ye-wax isebenzisa umjovo wensimbi. Iphethini izoba nayo yonke imininingwane yesigaba noma ingxenye yengxenye eqediwe kodwa enobukhulu obukhudlwana ukuze ibhekane nokufinyela okushisayo..
Olandelayo, unjiniyela udala umgijimi kanye nesistimu yokugenca ngokuxhuma amaphethini amaningi ukuze enze ingxenye yokugcina. Insimbi encibilikisiwe izogeleza ohlelweni lomgijimi njengoba igcwalisa izimbotshana esikhunjeni, ukwakha ukulingwa okulingana kahle. Amasango yizimbobo phakathi komgijimi kanye nembobo ephakela insimbi encibilikisiwe esikhaleni.
Uma yonke iphethini isiqediwe, icwiliswa odongeni lwe-ceramic futhi imbozwe nge-sand stucco. Unjiniyela wokuklama uphinda inqubo yokucwilisa kuze kube yilapho igobolondo lifinyelela ukujiya okufanele. Okwamanje, ukuqina kwegobolondo elomile kunamandla ngokwanele ukumelana nokushisa okuvela ensimbi encibilikisiwe. Futhi, izogcina isimo sayo phakathi nesinyathelo sokugcina.
I-wax iyancibilika ngaphansi kwamazinga okushisa aphezulu, futhi ulandele amanani acwiliswe kusimende noma isikhunta se-ceramic. Isikhala esishiywe iphethini ye-wax encibilikisiwe sizogcwaliswa nge-alloy ukuze kwakhiwe ingxenye enembile yensimbi engagqwali..
Ngaphambi kwalokho, phawula ukuthi insimbi iyingxubevange yensimbi ikakhulukazi ehlanganisa insimbi nekhabhoni kanye nezinye izakhi.
Nokho, insimbi engagqwali ingxubevange eyakhiwe inani elikhulu lokuqukethwe kwe-chromium ngokuvamile hhayi ngaphansi 10.5 % ngobuningi.
Yonke ingxenye yesisindo yakhiwe ngensimbi.
Ngokuphawulekayo, I-chromium inesibopho sokumelana nokugqwala ngakho-ke noma yikuphi ukwanda kwe-chromium kungenza insimbi imelane nokugqwala..
Ukwengeza, ngaphandle kwe-chromium, insimbi engagqwali nayo yakhiwe ezinye izithako ezifana:
Phakathi kwazo zonke lezi zingxenye ezincane, I-molybdenum ihluke ngokuphelele. Ithuthukisa kakhulu ukumelana nokugqwala kwensimbi engagqwali.
Lezi zinhlobo ziyinsimbi engagqwali 304 kanye nensimbi engagqwali 316
Ngakho-ke kusobala ukuthi kunezinhlobo eziningana zensimbi engagqwali ngaphandle kwalezi ezimbili ezivamile ezishiwo.
Umehluko phakathi kwazo ukwakheka kwawo kwengxubevange okuhlukile ngenxa yomehluko ekubunjweni kwamakhemikhali kanye nezakhiwo zawo ezihlukene zomzimba.
Ngakho-ke, amamaki angcono kakhulu okulingisa:
Kukhona "imindeni" eminingana yensimbi engagqwali. Ngamunye wale mikhaya unezilinganiso ezihlukene zensimbi, i-chromium, kanye nekhabhoni. Ezinye zinezinye izakhi, njenge-nickel, i-molybdenum, manganese, kumbe ithusi. Izici zalezi zinsimbi ziyahlukahluka ngokuqukethwe, okwenza lokhu kube yiqembu elihlukahlukene lama-alloys.
Amabanga anikeza inkomba mayelana nomndeni wensimbi ethile engagqwali. Amabanga avame kakhulu:
| Ingxubevange | Ukusetshenziswa Okuvamile | Izinhlelo zokusebenza |
| 304 | Insimbi yezinga lokudla, izindlu, imizimba 304 yamukelwa kabanzi embonini yokudla njengezinga lokuhlanzeka kanye nokumelana nokugqwala. | Ezokwelapha Izimayini I-Petrochemical |
| 304L/316L | Okufanayo nokunye 300 uchungechunge lwensimbi, i "L" imele ikhabhoni ephansi, ukuyenza ithambe kodwa imelane nokugqwala ebangeni ngalinye lempahla. | Ukudla & Ubisi Ezokwelapha I-Petrochemical |
| 316 | Izindlu, amagiya, amapuleti 316 yaziwa ngokumelana kwayo okuphakeme nokugqwala, ukuyenza ilungele ukusetshenziswa okuningi okuhlanganisa izindawo zasolwandle. | Ezezimoto I-Petrochemical Ukudla & Ubisi |
| 416 | Izindlu, amahlahla, izibambo, abakaki 400 ama-series steels angamandla aphezulu futhi asebenziseka kalula. Zizothambekela ekuqhekekeni kunokugoba ngaphansi kwengcindezi enkulu | Ezezimoto Ithuluzi Lomshini Ukudla & Ubisi |
| 17-4 | Izinduku, izikhonkwane, izixhumanisi, izingalo 17-4 inamandla kakhulu emndenini wensimbi engagqwali futhi isetshenziswa ezingxenyeni ezingakwazi ukugoba.. | Ezempi Ezokwelapha Ithuluzi Lomshini |
Ukusetshenziswa kwensimbi engagqwali kukhulu kakhulu, esetshenziswa kakhulu ngaphansi kwezimo ezehlukene zokugqwala kwabezindaba, ikakhulukazi ezinhlelweni ezidinga ukumelana nokugqwala kwemvelo, ekhombisa izinzuzo zayo eziyingqayizivele. Ubuchwepheshe bokukhipha insimbi engagqwali abufanele kuphela ukusakaza izinhlobo ezihlukahlukene nama-alloys, kodwa futhi ikhiqiza ukulingisa ngokunemba okuphezulu kwe-dimensional kanye nekhwalithi ephezulu kunezinye izindlela zokulingisa. Lobu buchwepheshe bufaneleka ngokukhethekile ukukhiqiza izinto eziyinkimbinkimbi, ukumelana nezinga lokushisa eliphezulu, futhi kunzima ukwenza umshini wokulingisa, ngisho nezimo eziyinkimbinkimbi okunzima ukuziphonsa kusetshenziswa ezinye izindlela zokulingisa, okungase kuzuzwe ngokusebenzisa insimbi engagqwali ukunemba casting ubuchwepheshe.
Ukulingisa kwensimbi engagqwali kunezinhlobonhlobo zezicelo zemakethe, kubandakanya kodwa kungagcini nje ngemikhiqizo yezimboni, ukukhiqiza imishini, imishini yamakhemikhali, ukwakhiwa kwemikhumbi, njll. Phakathi kwazo, insimbi engagqwali cast steel izingxenye ngokuvamile zisetshenziswa ngaphansi kwezimo ezonakalisayo ezihlukahlukene kwabezindaba ehlukahlukene. Ikakhulukazi ngemva kokutholakala ku 1910 ukuthi okuqukethwe kwe-Cr kunsimbi kudlule 12% futhi ibe nokugqwala okuhle nokungaguquki kwe-oxidation, ukusetshenziswa kwensimbi engagqwali kwasakazeka kakhulu. Ngaphezu kwalokho, izinsimbi zensimbi engagqwali zisetshenziswa kabanzi emikhakheni efana nemishini yamandla, amakhemikhali e-petrochemicals, kanye nokucubungula ukudla ukuze kuhlangatshezwane nezimo ezihlukahlukene eziyinkimbinkimbi nezidingo zohlelo lokusebenza.

Ukubunjwa kwensimbi engagqwali kungase kube nezimpande ezisukela emuva 5,000 iminyaka, kodwa isenazo izinhlelo zokusebenza ezizuzisayo emphakathini wanamuhla. Emhlabeni wonke, izimboni zithembele ensimbi engagqwali ekhonjiwe ukuze zikhiqize izingxenye zensimbi engagqwali eziyinkimbinkimbi eziqeda ubushelelezi, amajamo wejometri ahlukile, nokubekezelelana okuqinile, kuhlanganise nasolwandle, ezezimoto, imishini yokucubungula ukudla, kanye nezimboni zokukhiqiza izimoto.
I-DEZE Foundry inikezela ngezinsizakalo zokutshala izimali zensimbi engagqwali kanye nemishini yokwenza. Sisebenzisa inqubo ekhethekile yokusakazwa kwe-wax yokutshala imali ukwenza ngendlela oyifisayo izingxenye zensimbi engenasici ngokushesha. Uma ungathanda ukufunda okwengeziwe ngamasevisi ethu okusakaza futhi uthole isaphulelo samahhala kuphrojekthi yakho ezayo, xhumana nathi i-stainless steel foundrynamuhla.
