Nigute wakora ibirahure, nuburyo bukoreshwa muburyo bwo gukora ibirahuri Cn umwanditsi atangiza uburyo bukurikira.
1. Gufata: ukurikije urutonde rwibikoresho byateguwe, bapima ibikoresho fatizo bitandukanye hanyuma ubivange neza muri mixer.Ibikoresho nyamukuru byibirahure ni: umucanga wa quartz, hekeste, feldspar, ivu rya soda, aside boric, nibindi.
2. Gushonga, ibikoresho bibisi byateguwe bishyushya ubushyuhe bwinshi kugirango bibe ikirahuri kimwe cyuzuye ikirahure.Ubu ni inzira igoye cyane yumubiri na chimique.Gushonga ibirahuri bikorerwa mu itanura.Hariho ubwoko bubiri bwamashyiga: bumwe ni itanura rikomeye, aho ifiriti ishyirwa mubikonjo kandi igashyuha hanze yingenzi.Ikintu kimwe cyonyine gishobora gushyirwa mu itanura rito, kandi ingo zigera kuri 20 zishobora gushyirwa mu itanura rinini.Amatanura ya Crucible ni icyuho, kandi ubu ikirahure cya optique hamwe nikirahure cyamabara byakozwe mumatara akomeye.Ibindi ni itanura rya tanki, aho ifiriti yashongeshejwe muri pisine hanyuma igashyukwa numuriro ufunguye mugice cyo hejuru cyurwego rwamazi yikirahure.Ubushyuhe bwo gushonga bwikirahure ahanini ni 1300 ~ 1600 ゜ C. Benshi muribo bashyutswe numuriro, naho bake bashyutswe numuyagankuba, bita itanura ryamashanyarazi.Noneho, itanura ya tank ikorwa ubudahwema.Amatanura mato mato arashobora kuba metero nyinshi, kandi nini irashobora kuba nini nka metero zirenga 400.
3. Gukora ni uguhindura ibirahuri bishongeshejwe mubicuruzwa bikomeye bifite imiterere ihamye.Gukora birashobora gukorwa gusa mubipimo by'ubushyuhe runaka, aribwo buryo bwo gukonja.Ikirahure kibanza guhinduka kuva mumazi ya viscous kugeza kuri plastike, hanyuma ugahinduka muburyo bukomeye.Uburyo bwo gushiraho burashobora kugabanywa muburyo bwo gukora intoki no gukora imashini.
A. Gukora ibihimbano.Hariho kandi (1) kuvuza, ukoresheje nikel chromium alloy blow pipe, gufata umupira wikirahure no guhuha mugihe uhindukiriye.Ikoreshwa cyane cyane mugukora ibirahuri byinshi, amacupa, imipira (kubirahuri by'amaso), nibindi (2) Gushushanya: nyuma yo guhuha mubibyimba, undi mukozi abishyiraho isahani yo hejuru.Abantu bombi bavuza mugihe bakurura, bikoreshwa cyane mugukora ibirahuri cyangwa inkoni..Ikoreshwa cyane mugukora ibikombe, amasahani, nibindi.
B. Gukora imashini.Kubera imbaraga nyinshi zumurimo, ubushyuhe bwinshi nuburyo bubi bwo gukora ibihimbano, inyinshi murizo zasimbuwe no gukora imashini usibye gukora kubuntu.Usibye gukanda, kuvuza no gushushanya, gukora imashini bifite kandi (1) uburyo bwo guhitamo, bukoreshwa mugukora ibirahuri binini cyane, ikirahure cyanditseho, ikirahure cyinsinga, nibindi (2) Uburyo bwo guta kugirango butange ibirahuri byiza.
C.Uku nugutera inshinge ikirahure mumashanyarazi yihuta cyane.Bitewe n'imbaraga za centrifugal, ikirahuri gifatanye nurukuta rwubatswe, kandi kuzenguruka birakomeza kugeza ikirahure gikomeye.(4) Uburyo bwo gucumura bukoreshwa mukubyara ibirahuri.Nukwongeramo ibibyimba ifu yikirahure hanyuma ukabishyushya mubyuma bitwikiriye.Ibibyimba byinshi bifunze bikozwe muburyo bwo gushyushya ikirahure, nikintu cyiza cyo kubika ubushyuhe nibikoresho byogukoresha amajwi.Mubyongeyeho, gukora ibirahuri binini birimo uburyo bwo gushushanya buhagaritse, uburyo bwo gushushanya buringaniye hamwe nuburyo bwo kureremba.Uburyo bwa Float nuburyo butuma ikirahuri cyamazi kireremba hejuru yicyuma gishongeshejwe (TIN) gukora ikirahure kibase.Ibyiza byingenzi byingenzi ni ikirahure cyiza (kiringaniye kandi kimurika), gushushanya byihuse hamwe nibisohoka binini.
4. Nyuma yo gufatana, ikirahuri gihinduka cyane mubushyuhe no guhindura imiterere mugihe cyo gukora, ibyo bigatuma ubushyuhe bwumuriro mubirahure.Uku guhangayikishwa nubushyuhe bizagabanya imbaraga nubushyuhe bwibicuruzwa byibirahure.Niba ikonje mu buryo butaziguye, birashoboka ko yaturika ubwayo mugihe cyo gukonjesha cyangwa kubika nyuma, gutwara no gukoresha (bikunze kwitwa guturika kwikirahure gikonje).Kugirango ukureho iturika rikonje, ibicuruzwa byibirahure bigomba kumanikwa nyuma yo kubikora.Annealing nugukomeza ubushyuhe mubipimo byubushyuhe runaka cyangwa gutinda mugihe runaka kugirango ukureho cyangwa ugabanye ubushyuhe bwumuriro mubirahure kugeza agaciro kemewe.
Byongeye kandi, ibicuruzwa bimwe byikirahure birashobora gukomera kugirango byongere imbaraga.Harimo: gukomera kumubiri (kuzimya), gukoreshwa mubirahure binini, ibirahuri bya tabletop, ibirahuri by'imodoka, nibindi;Kandi imiti igabanya ubukana (ion guhana), ikoreshwa mubirahure by'ikirahure, ikirahure cy'indege, n'ibindi. Ihame ryo gukomera ni ugutera imbaraga zo kwikuramo hejuru yikirahure kugirango wongere imbaraga.
