I-Steel castings inhlanganisela yenqubo yokubumba nokusansimbi kwensimbi. Abakwazi nje ukuba nesakhiwo esiyinkimbinkimbi okunzima ukukuthola ngezinye izinqubo zokwakha, kodwa futhi balondoloze izakhiwo eziyingqayizivele zensimbi, ngakho-keizingxenye zokuphonsa insimbibabe nesikhundla esiphezulu esibalulekile ezintweni zokwakha zobunjiniyela. Ezimbonini eziningi, ukukhishwa kwensimbi kukhiqizwa ikakhulukazi ngalezi zinqubo eziningana zokuphonsa: ukufakwa kwe-investimenti, ukukhishwa kwegwebu elilahlekile, ukuphonsa kwe-vacuum, ukuphonsa kwesihlabathi kanyeukukhishwa kwesihlabathi se-resin camera.
Izinsimbi zensimbi nazo ziningi kakhulu mayelana nokukhethwa kwensimbi ne-alloy. Ngokwesibonelo, insimbi cast ihlanganisa anhlobonhlobo Alloys ezifana ongaphakeme carbon steel, medium carbon steel, high carbon steel, ingxubevange steel, high ingxubevange steel,insimbi engagqwali, insimbi engagqwali eyi-duplex, imvula yenza lukhuni ingagqwali namanye ama-alloys ensimbi akhethekile.
Insimbi ye-carbon steel ne-low-alloy steel inamandla aphezulu, ukuqina okuphezulu nokushisela okuhle, futhi ingalungisa izakhiwo zemishini ebangeni elibanzi ngezinqubo ezahlukene zokwelashwa kokushisa. Ziyizinto ezisetshenziswa kakhulu zesakhiwo sobunjiniyela. Kwezinye izimo ezikhethekile zobunjiniyela, njengokumelana nemihuzuko, ukumelana nengcindezi, ukumelana nokushisa, ukumelana nokugqwala kanye nokumelana nezinga lokushisa eliphansi, kunezinhlobonhlobo zezinsimbi ze-alloy eziphakeme ezinezakhiwo ezikhethekile ezihambisanayo ongakhetha kuzo.
Izingxenye zensimbi ezakhiwe nazo zinezinzuzo zazo, njengamandla aphakeme kanye nokukhubazeka okumbalwa kwangaphakathi. Kodwa-ke, uma kuqhathaniswa nezingxenye zensimbi ezibunjiwe, izinzuzo zokubunjwa kwensimbi nazo zisobala. Kafushane, izinzuzo ze-castings zensimbi zibonakaliswa ngokuyinhloko ekuguquguqukeni kokuklama. Ngokukhethekile, lokhu kuvumelana nezimo kubonakala kulezi zici ezilandelayo:
I-1) Isakhiwo se-castings yensimbi sinokuguquguquka okuphezulu
Abasebenzi bezobuchwepheshe bemboni yokuphonsa insimbi bangaba nenkululeko enkulu yokuklama ekubunjweni nasekusayizini wensimbi, ikakhulukazi izingxenye ezinobumo obuyinkimbinkimbi nezigaba ezingenalutho. Ama-castings ensimbi angenziwa ngenqubo eyingqayizivele yokuhlanganisa okuyisisekelo. Ngesikhathi esifanayo, ukubunjwa nokushintshwa kwesakhiwo sensimbi kulula kakhulu, futhi isivinini sokuguqulwa kusuka ekudwebeni kuya kumkhiqizo oqediwe sishesha kakhulu, esivumelana nempendulo yengcaphuno esheshayo kanye nesikhathi sokulethwa esifushane.
I-2) Ukukhiqizwa kwe-metallurgical of castings yensimbi kunokuguquguquka okuphezulu nokuguquguquka
Ngenjwayeloizisekelo, izinsimbi zensimbi zingaba nezinhlobo eziningi zamakhemikhali ezihlukene ongakhetha kuzo, njengensimbi ye-carbon ephansi, insimbi ye-carbon steel, i-high carbon steel, insimbi ephansi ye-alloy, insimbi ephezulu ye-alloy nensimbi ekhethekile. Ngaphezu kwalokho, ngokuya ngezidingo ezihlukile zokusebenza kwe-castings yensimbi, i-foundry ingaphinda ikhethe izakhiwo zemishini futhi isebenzise ukusebenza ebangeni elikhudlwana ngokusebenzisa izindlela zokwelapha ezihlukene zokushisa, futhi ngesikhathi esifanayo, ingathola nokusebenza okuhle kwe-welding nokusebenza komshini.
I-3) Isisindo se-castings yensimbi singahluka ngaphakathi kwebanga elibanzi
Ukukhishwa kwensimbi kungafinyelela isisindo esincane samagremu ambalwa, njengokudlulaukutshala imali. Isisindo sezinsimbi ezinkulu zensimbi zingafinyelela amathani amaningana, amathani amaningi noma ngisho namakhulu amathani. Ngaphezu kwalokho, ukukhishwa kwensimbi kulula ukufeza umklamo ongasindi, onganciphisi kuphela isisindo sokuphonsa (okubaluleke kakhulu ezimbonini zezimoto zabagibeli, isitimela, nemikhumbi), kodwa futhi kunciphisa izindleko zokuphonsa.
4) Ukuguquguquka kokukhiqizwa kwensimbi
Enqubweni yokwenza insimbi, izindleko zesikhunta ziyisici esingenakunakwa. Uma kuqhathaniswa nezingxenye zensimbi ezenziwe ngomgunyathi, ukulingisa kwensimbi kungathatha izinqubo zokuphonsa ezihlukene ngokwezidingo ezahlukene. Ukuze uthole ukukhishwa kwe-single-piece noma i-batch encane, amaphethini okhuni noma amaphethini we-polystyrene gasification angasetshenziswa, futhi umjikelezo wokukhiqiza mfushane kakhulu. Ngokusakazwa kwensimbi enesidingo esikhulu uma kuqhathaniswa, amaphethini epulasitiki noma ensimbi angasetshenziswa, futhi izindlela ezifanele zokumodela zisetshenziswa ukwenza ukulingisa kube nokunemba kwe-dimensional edingekayo kanye nekhwalithi ephezulu. Lezi zici kunzima ukuzifeza ngezingxenye zensimbi ezakhiwe.
