Nka gikoresho cyingenzi mubuhanga bugezweho bwo gukina,silicon karbide irakomeyebuhoro buhoro yahindutse ikintu cyatoranijwe cyo gushonga ibyuma bidafite fer kubera imikorere myiza nibintu byihariye. Cyane cyane iyo gutunganya ubushyuhe bwo hejuru bwicyuma gishonga, umusaraba wa karubide ya silicon yerekana urukurikirane rwibyiza bya tekiniki. Iyi ngingo izerekana mu buryo burambuye imikorere iranga silikoni ya karbide, ikoreshwa ryayo mugikorwa cyo gukina, nuburyo bwo gutanga ibisubizo byiza kandi byizewe kumasosiyete agezweho ya casting.
1. Carbide ya silicon ni iki?
Carbide ya Silicon ni ikintu cyubushyuhe bwo hejuru ukoresheje karibide ya silicon (SiC) nkibikoresho nyamukuru. Ikoreshwa cyane cyane mu gushonga no gutunganya ibyuma bitandukanye na alloys. Carbide ya Silicon ni ibikoresho byubukorikori bifite ubukana bukabije kandi birwanya ubushyuhe. Ikoreshwa cyane mubice byubuhanga buhanitse nka ceramics, metallurgie, na semiconductor.
Kuberako umusemburo wa karubide ya silicon ufite ibintu byiza byumubiri nubumara nkubushyuhe bwo hejuru bwumuriro mwinshi, coefficente yo kwagura ubushyuhe buke, hamwe no kurwanya ruswa, byerekana ituze ntagereranywa hamwe nigihe kirekire mugihe cy'ubushyuhe bwinshi kandi mubihe bikabije.
2. Ibyiza bya tekinike ya silicon karbide ikomeye
1. Kurwanya ubushyuhe buhebuje
Imisaraba ya karibide ya silicon ifite ubushyuhe bwinshi cyane kandi irashobora kwihanganira ubushyuhe burenga 1600 ° C. Ibi bituma biba byiza gushonga ibyuma byo hejuru cyane nkumuringa, aluminium na nikel. Ugereranije n'umusaraba wakozwe mubindi bikoresho, imbaraga za kariside ya silicon karbide ntizigabanuka cyane mugihe cy'ubushyuhe bwo hejuru, bigatuma imiterere yayo ihagarara mugihe cyo gushonga.
Uku kurwanya ubushyuhe bwo hejuru cyane bifasha ibigo kwirinda ingenzi zidahinduka cyangwa guturika bitewe nubushyuhe bwinshi, bityo bigatuma umusaruro ukomeza kandi neza.
2. Amashanyarazi meza cyane
Ikindi kintu kigaragara cyibikoresho bya silicon karbide nubushyuhe bwayo bwinshi, butuma byihuta ndetse nubushyuhe. Ibi bivuze ko mugihe cyo gushonga, icyuma gishongeshejwe gishobora kugera vuba kubushyuhe bukenewe, bikagabanya igihe cyo gushonga no kuzamura umusaruro.
Ubu buryo bwiza bwo gutwara ubushyuhe bugabanya kandi ubushyuhe bwicyuma gishongeshejwe, bifasha kugera ku kugenzura neza ubushyuhe mugihe cyo gutera no kwemeza ubuziranenge bwa casting.
3. Coefficient yo kwagura ubushyuhe buke
Coefficient yo kwagura ubushyuhe bivuga urugero ibintu byaguka mubunini iyo bishyushye. Carbide ya Silicon ifite coefficient nkeya cyane yo kwagura ubushyuhe, bivuze ko ihinduka bike mubunini iyo ishyushye. Kubwibyo, no mubidukikije bifite ihindagurika rikabije ryubushyuhe, karbide ya silicon irashobora gukomeza imiterere yumwimerere kandi ikirinda gucika cyangwa kwangirika bitewe no kwaguka cyangwa kwikuramo.
Kwiyongera k'ubushyuhe buke birakwiriye cyane cyane muburyo bwo gutara burimo gushyushya kenshi no gukonjesha, byongerera cyane ubuzima bwa serivisi zingenzi.
4. Kurwanya ruswa nziza
Mugihe cyo gushonga, icyuma gishongeshejwe gikora hamwe ningirakamaro, buhoro buhoro cyangirika hejuru yacyo. Nyamara, ibikoresho bya kariside ya silicon bifite imiti irwanya ruswa kandi birashobora kurwanya isuri y’amazi y’icyuma, cyane cyane iyo ikorana n’ibyuma byangiza cyane nk'umuringa na aluminium.
Kurwanya ruswa neza ntabwo byongerera igihe umurimo wigihe cyibikorwa byingenzi, ahubwo binagabanya umwanda wanduye uterwa no kwangirika hejuru yingenzi, bikomeza kweza amazi yicyuma no kuzamura ubwiza bwibicuruzwa byanyuma.
5. Imbaraga zikomeye
Silicon carbide crucibles ikomeza imbaraga zubukanishi ndetse no mubushyuhe bwinshi, bigatuma bidashoboka kumeneka cyangwa guhinduka. Izi mbaraga zikomeye ziranga abashobora kwihanganira ingaruka zicyuma gishongeshejwe hamwe nubukanishi bwo hanze, bikomeza guhagarara neza mugihe ubushyuhe bwo hejuru.
6. Guhagarika ubushyuhe bwiza
Ubushyuhe bukabije bwumuriro bivuga ubushobozi bwibikoresho byo kurwanya gucika iyo ubushyuhe buhindutse vuba. Silicon carbide crucibles yerekana ihungabana ryiza ryumuriro kandi irashobora kwihanganira ihinduka ryubushyuhe bwihuse nta guturika. Ibi nibyingenzi byingenzi mubikorwa byo gukina bisaba gushyuha no gukonja.
bitatu. Gukoresha silicon karbide ikomeye
Bitewe nubushyuhe bwo hejuru bwo guhangana nubushyuhe, ubushyuhe bwumuriro, hamwe no kurwanya ruswa, umusaraba wa karibide ya silicon ikoreshwa cyane muburyo butandukanye bwo gushonga ibyuma no guterera, cyane cyane mu gushonga ibyuma bidafite fer na fer. Ibikurikira nibintu byinshi bisanzwe bikoreshwa:
Gutera umuringa: Iyo ushonga umuringa,silicon karbide irakomeyes irashobora kugumana ubushyuhe bwubushyuhe bumwe, kugabanya imiterere yimyanda, no kuzamura ubwiza bwibice byumuringa.
Amashanyarazi ya aluminium na aluminiyumu: Aluminiyumu yoroha cyane hamwe ningirakamaro mugihe cyo gushonga, ariko kurwanya ruswa ya karubide ya silicon irinda neza ingenzi kwangirika kwa aluminiyumu kandi ikongerera igihe cyo gukora.
Ubundi ubushyuhe bwo hejuru bwo gushonga: Carbide ya Silicon irakomeye kandi irakwiriye gushonga ibyuma byo hejuru cyane nka zinc na nikel, kandi bifite imiterere ihindagurika.
Bane. Koresha no gufata neza karbide ya silicon ikomeye
Kongera ubuzima bwa serivisi ya silicon carbide yabambwe, gukoresha neza no kubungabunga ni ngombwa. Dore bimwe mu bitekerezo:
Shyushya ibyingenzi: Mbere yo gukoresha bwa mbere cyangwa kongera gukoresha, birasabwa guhita ushushanya buhoro buhoro ubushyuhe bukora kugirango wirinde ubushyuhe butunguranye.
Irinde gushyushya byihuse no gukonjesha: Nubwo umusaraba wa karibide ya silicon ufite umutekano muke uhindagurika, ihinduka ryubushyuhe bwihuse rirashobora kwangiza ingirakamaro.
Igenzura risanzwe: Mugihe cyo gukoresha, genzura buri gihe hejuru yubuso bwerekana ibimenyetso byacitse cyangwa byangirika, kandi ukemure ibibazo bishobora kuvuka mugihe gikwiye.
