Imashini zikomeza
Ihame ryimikorere yubwoko busanzwe bwimashini ikomeza gushingira kubitekerezo bisa nkimashini zitera vacuum. Aho kuzuza ibintu byamazi muri flask urashobora kubyara / gushushanya urupapuro, insinga, inkoni, cyangwa umuyoboro ukoresheje ibishushanyo mbonera. Ibi byose bibaho nta mwuka uhumeka cyangwa kugabanuka. Imashini ya vacuum hamwe na vacuum ihoraho ikomeza gukoreshwa cyane cyane mugukora insinga zo murwego rwohejuru nko guhuza insinga, semiconductor, ikibuga cyindege.
Gukomeza gukina ni iki, ni iki, ni izihe nyungu?
Uburyo bukomeza bwo gutara ni uburyo bwiza cyane bwo gukora ibicuruzwa bitarangiye nkutubari, imyirondoro, ibisate, imirongo hamwe nigituba bikozwe muri zahabu, ifeza nibyuma bidafite fer nkumuringa, aluminium na alloys.
Nubwo haba hari uburyo butandukanye bwo gukomeza gukina, nta tandukaniro rikomeye mugutera zahabu, ifeza, umuringa cyangwa ibivanze. Itandukaniro ryingenzi nubushyuhe bwa casting buri hagati ya 1000 ° C mugihe cya feza cyangwa umuringa kugeza kuri 1100 ° C mugihe cya zahabu cyangwa ibindi bivanze. Icyuma gishongeshejwe gikomeza gutabwa mu cyombo kibikwa cyitwa ladle kandi gitemba kiva aho kigana mu buryo buhagaritse cyangwa butambitse. Mugihe gitembera mubibumbano, bikonjeshwa na kristalisiti, ubwinshi bwamazi bufata umwirondoro wububiko, bugatangira gukomera hejuru yacyo hanyuma bugasiga ifumbire mumurongo wigice gikomeye. Icyarimwe, gushonga gushya guhora bitangwa kububiko ku kigero kimwe kugirango ukomeze umurongo ukomeye uva mubibumbano. Umugozi urakonjeshwa hakoreshejwe uburyo bwo gutera amazi. Binyuze mu gukoresha ubukonje bukabije birashoboka kongera umuvuduko wa kristu no kubyara umurongo umwe umwe, ufite ingano nziza itanga igice cyarangije ibicuruzwa byiza byikoranabuhanga. Umugozi ukomeye urakosorwa hanyuma ukagabanywa kugeza uburebure bwifuzwa nogosha cyangwa gukata-itara.
Ibice birashobora gukomeza gukorerwa mubikorwa bizakurikiraho kumurongo wo kuzunguruka kugirango ubone utubari, inkoni, fagitire zo gukuramo (ubusa), ibisate cyangwa ibindi bicuruzwa byarangije igice muburyo butandukanye.
Amateka yo gukomeza gukina
Kugerageza bwa mbere gutera ibyuma muburyo bukomeza byakozwe hagati yikinyejana cya 19. Mu mwaka wa 1857, Sir Henry Bessemer (1813–1898) yahawe ipatanti yo gutera ibyuma hagati yimizingo ibiri izunguruka yo gukora ibyuma. Ariko icyo gihe ubu buryo bwakomeje kutitabwaho. Iterambere rikomeye ryatewe kuva 1930 gukomeza hamwe na tekinike ya Junghans-Rossi yo guhora utera urumuri nicyuma kiremereye. Kubyerekeranye nicyuma, uburyo bwo gukomeza guterana bwakozwe mu 1950, mbere (na nyuma yaho) ibyuma bisukwa mububiko buhagaze kugirango bibe 'ingots'.
Gukomeza gutera inkoni idafite ferrous byakozwe na Properzi, byakozwe na Ilario Properzi (1897-1976), washinze sosiyete ya Continuus-Properzi.
Ibyiza byo gukomeza gukina
Gukomeza gukina nuburyo bwiza cyane bwo gukora igice cyarangije ibicuruzwa bifite ubunini burebure kandi butuma umusaruro mwinshi mugihe gito. Microstructure yibicuruzwa niyo ndetse. Ugereranije no guteramo ibishushanyo, guhora utera ni ubukungu bijyanye no gukoresha ingufu kandi bigabanya ibicuruzwa bike. Byongeye kandi, imiterere yibicuruzwa irashobora guhinduka byoroshye muguhindura ibipimo bya casting. Nkuko ibikorwa byose bishobora guhita byikora kandi bikagenzurwa, guhora gukina bitanga uburyo bwinshi bwo guhuza umusaruro muburyo bwihuse kandi bwihuse kugirango uhindure ibisabwa ku isoko no kuyihuza na tekinoroji ya digitale (Industrie 4.0).
