Kungase kubonakale kusobala ukuthi ukwazi ukuthi iyiphi ongayisebenzisa kungasiza ekugwemeni ukuchitha imali engaphezu kwalokho edingekayo ezintweni ezingavuthiwe.Ingase futhi yonge isikhathi nemali ekucubunguleni okwengeziwe.Ngamanye amazwi, ukuqonda umehluko phakathi kwensimbi egoqiwe eshisayo nebandayo kuzosiza abaklami nonjiniyela bathole imiphumela engcono-futhi ngentengo engcono kakhulu.
Umehluko oyisisekelo phakathi kwalezi zinhlobo ezimbili zensimbi ungomunye wenqubo.Njengoba ungacabanga,“hot rolling”isho ukucubungula okwenziwe ngokushisa.“Ukuginqika okubandayo”ibhekisela ezinkambisweni ezenziwa ezingeni lokushisa legumbi noma eduze nalo.Nakuba lawa masu athinta ukusebenza kwawo wonke kanye nokusetshenziswa kwawo, akufanele adidaniswe nokucaciswa okusemthethweni namabanga ensimbi, ahlobene nokubunjwa kwe-metallurgical kanye nezilinganiso zokusebenza.Izinsimbi zamabanga ahlukene kanye nezicaciso zingaba zishise zigoqwe noma zigoqwe ngokubanda-okuhlanganisa i-carbon eyisisekelo nezinye izinsimbi ze-alloy.
Insimbi egoqwe eshisayo icindezelwe emazingeni okushisa aphezulu (ngaphezu kuka-1,700˚F), engaphezulu kwezinga lokushisa le-crystallization yezinsimbi eziningi.Lokhu kwenza insimbi yakheke kalula, futhi kuphumela emikhiqizweni okulula ukusebenza ngayo.
Ukucubungula insimbi egoqiwe eshisayo, abakhiqizi baqala nge-billet enkulu, engunxande.I-billet iyashiswa futhi ithunyelwe ukuze icutshungulwe ngaphambili, lapho ihlelwa khona ibe umqulu omkhulu.Ukusuka lapho, igcinwa ezingeni lokushisa eliphezulu, futhi insimbi ecwebezelayo eshisayo iqhutshwa ngochungechunge lwamarola okucindezela ukuze kuzuzwe ubukhulu bayo obuphelile.Ngeshidi lensimbi, abakhiqizi baphotha insimbi egoqiwe ibe amakhoyili futhi bayishiye ukuze iphole.Kwamanye amafomu, njengemigoqo namapuleti, izinto zokwakha zihlukaniswa futhi zipakishwe.
Insimbi ishwabana kancane njengoba iphola.Ngenxa yokuthi insimbi egoqiwe eshisayo iyapholiswa ngemva kokucubungula, kukhona ukulawula okuncane kokuma kwayo kokugcina, okuyenza ingalungeli kakhulu ukusetshenziswa okunembayo.Insimbi egoqiwe eshisayo ivamise ukusetshenziswa uma izilinganiso ezithize kancane zingekho't kubalulekile-emizileni yesitimela nakumaphrojekthi wokwakha, isibonelo.
Insimbi egoqiwe eshisayo ingabonakala ngalezi zici ezilandelayo:
•Izindawo ezilinganisiwe, izinsalela zokupholisa kusuka kumazinga okushisa aphezulu.
•Imiphetho namakhona ayindilinga kancane wemikhiqizo yebha namapuleti (ngenxa yokuncipha nokuqedwa okunembayo okuncane).
•Ukuhlanekezela okuncane, lapho ukupholisa kungase kushiye amafomu e-trapezoidal kancane kunama-engeli ayisikwele ngokuphelele.
Insimbi egoqwe eshisayo ivamise ukudinga ukucutshungulwa okuncane kakhulu kunensimbi egoqiwe ebandayo, okuyenza ingabizi kakhulu.Insimbi egoqwe eshisayo nayo ivunyelwe ukupholisa ekamelweni lokushisa, ngakho-ke's empeleni evamile, okusho ukuthi's ikhululekile ekucindezelekeni kwangaphakathi okungavela ngesikhathi sokucisha noma izinqubo zokuqinisa umsebenzi.
Insimbi egoqiwe eshisayo ilungile lapho ukubekezelelana kwe-dimensional kukhona't kubaluleke njengamandla ezinto ezibonakalayo, nalapho ukuphela kwendawo engekho'ukukhathazeka okubalulekile.Uma ukuqedwa kwendawo kuyinkinga, ukukala kungasuswa ngokugaya, ukuqhunyiswa kwesihlabathi, noma ukugcotshwa kwe-asidi yokugeza.Uma ukukala kususiwe, kungasetshenziswa ibhulashi noma izibuko ezihlukahlukene.Insimbi encishisiwe iphinde inikeze indawo engcono yokudweba nezinye izinto zokumboza.
Insimbi egoqiwe ebandayo empeleni iyinsimbi egoqwe eshisayo esedlule ekucutshungulweni okwengeziwe.Ukuze bathole insimbi egoqiwe ebandayo, abakhiqizi ngokuvamile bathatha insimbi egoqwe epholile epholile bese beyigingqa ngokwengeziwe ukuze bathole ubukhulu obunembe kakhudlwana nezimfanelo ezingcono zendawo.
Kodwa igama“ginqika”ivamise ukusetshenziselwa ukuchaza uhla lwezinqubo zokuqeda ezifana nokujika, ukugaya, nokupholisha, ngayinye elungisa isitoko esivele sikhona esigoqiwe sibe yimikhiqizo ecwengisiswe kakhulu.Ngokobuchwepheshe,“abandayo rolling”isebenza kuphela kumashidi acindezelwa phakathi kwamarola.Kodwa amafomu afana nemigoqo noma amashubhu anjalo“udwetshiwe,”hhayi rolling.Ngakho-ke imigoqo egoqiwe eshisayo namashubhu, uma esepholile, acutshungulwa abe yilokho okubizwa“amakhaza aphelile”amashubhu nemigoqo.
Insimbi egoqiwe ebandayo ingabonakala ngalezi zici ezilandelayo:
•Izindawo eziningi eziqediwe ezinokubekezelelana okuseduze.
•Izindawo ezibushelelezi ezivame ukuba namafutha uma uthintwa.
•Amabha ayiqiniso futhi ayizikwele, futhi ngokuvamile anemiphetho namakhona achazwe kahle.
•Amashubhu anokufana okugxilile okungcono nokuqondile.
Enezici ezingcono ezingaphezulu kunensimbi egoqiwe eshisayo, yona'Akumangazi ukuthi insimbi egoqiwe ebandayo ivame ukusetshenziselwa izinhlelo zokusebenza ezinembe kakhulu noma lapho ubuhle bubalulekile.Kodwa, ngenxa yokucubungula okwengeziwe kwemikhiqizo ebandayo ephelile, iza ngentengo ephakeme.
Ngokuya ngezici zabo zomzimba, ukwelapha okubandayo kungadala nokucindezeleka kwangaphakathi ngaphakathi kwempahla.Ngamanye amazwi, ukwakha insimbi esebenzayo ebandayo-kungaba ngokuyisika, ukuyigaya, noma ukuyishisela-kungakhulula ukungezwani futhi kuholele ekungqubuzaneni okungalindelekile.
Kuye ngokuthi wena'kabusha ufuna ukwakha, izinhlobo ezahlukene zezinto ngayinye inezinzuzo zayo kanye nezinkinga zayo.Kumaphrojekthi ahlukile noma ukukhiqizwa okukodwa, izinto zensimbi ezenziwe ngaphambilini zinganikeza amabhulokhi wokwakha kunoma yikuphi ukucushwa kwesakhiwo ongakucabanga.
Kumaphrojekthi lapho uzobe ukhiqiza amayunithi amaningi, ukusakaza kungenye inketho engonga isikhathi ekwenzeni imishini nokuhlanganisa.Izingxenye ze-Cast zingenziwa cishe kunoma yiluphi uhlobo kuhlu lwezinto zekhwalithi.
