Igisubizo gihujwe na silicon karbide Crucible
Ibicuruzwa nibyiza kumatara yinganda, gucumura, gushonga kandi bikoreshwa muburyo bwose bwibicuruzwa. Mu rwego rwinganda zikora imiti, peteroli no kurengera ibidukikije hamwe nibikorwa byinshi.
1) Ubushyuhe bukabije
2) Imiti irwanya ruswa
3) Ubushyuhe bwinshi-kwihanganira (kugeza kuri 1650 °
4) Kwambara / kwangirika / kurwanya okiside
5) Gukora cyane imbaraga zubukanishi
6) Gusukura cyangwa gutobora ibintu bigoye cyane
7) Ikoreshwa mu gusya, gukubita, no kubona insinga gukata kimwe no guturika

Ibisobanuro:
Ikintu gikomeye ni inkono yubutaka ikoreshwa mu gufata ibyuma byo gushonga mu itanura. Nibintu byiza cyane, urwego rwinganda rukoreshwa ninganda zubucuruzi.
Icyo ikora:
Birakenewe cyane kugirango uhangane n'ubushyuhe bukabije bugaragara mu gushonga ibyuma. Ibikoresho byingenzi bigomba kuba bifite aho bihurira cyane kuruta icyuma gishonga kandi kigomba kugira imbaraga nziza nubwo cyera gishyushye.
Birashoboka gukoresha inzu ikozwe mubyuma kugirango ibashe gushonga ibyuma nka zinc na aluminium, kuko ibyo byuma bishonga mubushyuhe buri munsi yicyuma. Nyamara gupima (flaking) byicyuma cyimbere imbere ni ikibazo. Iki gipimo kirashobora kwanduza gushonga no kunanura inkuta zikomeye ariko vuba. Kubambika ibyuma bizakora niba urimo gutangira kandi ntutinye guhangana nubunini.
Ibikoresho bisanzwe bivunika bikoreshwa mubwubatsi bukomeye ni ibumba-grafite, na karubone ihujwe na silicon-karbide. Ibi bikoresho birashobora kwihanganira ubushyuhe bwo hejuru mubikorwa bisanzwe byo gushinga. Carbide ya Silicon ifite inyungu zo kuba ibikoresho biramba cyane.
Ibumba ryacu rya Clay Graphite Bilge Ifite ibipimo bya 2750 ° F (1510 ° C). Bazakora zinc, aluminium, umuringa / umuringa, ifeza na zahabu. Uruganda ruvuga ko rushobora gukoreshwa mu byuma. Byakozwe muri Amerika!
Imiterere y'ingenzi:
Ikirangantego gifite ishusho (“B” Ishusho) ingirakamaro kimeze nka barri ya vino. Igipimo cya "bilge" ni diametre y'ibyingenzi ahantu hanini cyane. Niba nta diameter ya bilge yerekanwe noneho diameter yo hejuru nubugari ntarengwa.
Itegeko ngenderwaho rivuga ko # ya "bilge" ikomeye itanga ubushobozi bwayo bwo gukora muri pound ya aluminium. Kumuringa cyangwa umuringa koresha inshuro 3 ingenzi #. Kurugero # 10 ingirakamaro yatwara hafi ibiro 10 bya aluminium na pound 30 yumuringa.
Imiterere ya “B” imiterere yacu isanzwe ikoreshwa na hobbiests hamwe na casters kenshi. Ibi nibyiza cyane, birebire urwego rwubucuruzi rurambye.
Reba imbonerahamwe ikurikira kugirango ubone ingano ikwiye kumurimo wawe.
Uburyo bwo Kubikoresha:
Ibibumbano byose bigomba gukemurwa neza (igikoresho cyo guterura). Indimi zidakwiye zirashobora gutera ibyangiritse cyangwa gutsindwa burundu kubintu byingenzi mugihe kibi gishoboka.
Disiki yikarito irashobora gushyirwa hagati yingenzi nitanura mbere yo gushyushya. Ibi bizashya, hasigare igice cya karubone hagati kandi birinde ikibuza gukomera kumatara. Igifuniko cya Plumbago (Carbon Black) gikora ikintu kimwe.
Nibyiza gukoresha ikindi kintu cyingenzi kuri buri bwoko bwicyuma kugirango wirinde kwanduza. Wemeze kandi gusiba burundu ingirakamaro nyuma yo gukoreshwa. Icyuma gisigaye kugirango gikomere cyane kirashobora kwaguka mukongera gushyushya no kukisenya.
Nyamuneka nyamuneka umusaraba mushya cyangwa uwabitswe. Shyushya ubusa mumasaha 2 kuri 220 F (104 C). . Emera ibikomeye gukonjesha ubushyuhe bwicyumba mu itanura mbere yo gukoresha. Ubu buryo bugomba gukurikizwa kubintu byose bishya byabambwe ndetse no kubintu byose byingenzi bishobora kuba byaragaragaye mubihe bitose mububiko.
Bika umusaraba wose ahantu humye. Ubushuhe burashobora gutera ikintu gikomeye kumena ubushyuhe. Niba yarabitswe mugihe gito nibyiza gusubiramo ubushyuhe.
Silicon carbide crucibles nubwoko bushoboka cyane bwo gufata amazi mububiko kandi mubisanzwe ntibigomba guhinduka mbere yo kuyakoresha. Nibyiza ko uzimya ikintu gishya gikomeye kubushyuhe butukura mbere yo gukoreshwa bwa mbere kugirango wirukane no gukomera uruganda rukora hamwe na binders.
Ibikoresho bigomba gushyirwa mubikomeye CYANE. NTUKIGERE “gupakira” ikintu gikomeye, kuko ibikoresho bizaguka kubushyuhe kandi birashobora kumena ceramic. Iyo ibi bikoresho bimaze gushonga "agatsinsino", shyira witonze ibintu byinshi mumazi kugirango ushonge. . Na none kandi, ntugapakire neza mubyuma. Komeza kugaburira ibikoresho gushonga kugeza igihe bisabwa bishonge.
UMUBURO !!!: Kubambwa ni akaga. Gushonga ibyuma mubikomeye ni bibi. Gusuka ibyuma mubibabi ni bibi. Ikomeye irashobora kunanirwa nta nteguza. Kubambwa birashobora kuba birimo inenge zihishe mubikoresho no mubikorwa bishobora gutera kunanirwa, kwangirika kwumutungo, gukomeretsa umuntu ku giti cye, gukomeretsa abari hafi no gutakaza ubuzima.

Ibisobanuro:
BCS Ikibanza fatizo nikibanza cyo hejuru cyubushyuhe bukoreshwa mukuzamura ikintu gikomeye kuri zone yubushyuhe bwitanura.
Icyo ikora:
Ikibanza fatizo gikunze gukoreshwa mu itanura rya gaz ryakoreshejwe kugirango uzamure hejuru kugirango urumuri rutwika rudaturika mu rukuta ruto rw'ingenzi. Niba urumuri rwaka rwemerewe gukubita ku buryo butaziguye birashobora gutera isuri kurukuta rwumusaraba bityo bikagabanya ubuzima bwarwo. Inzira nziza yo gukumira ibi ni ugukoresha ibice fatizo kugirango uzamure ingirakamaro hanze ya zone.
Kuzamura ibyingenzi binemerera kuba muri "hot zone" y'itanura. Nubwo urumuri rwaka rwinjira mumubiri witanura hepfo zone ishyushye cyane kuva hagati kugeza hejuru. Muri kano karere niho inkuta z'itanura zashyutswe na gaze izenguruka neza. Kugira impande zingenzi muri kano karere biteza imbere ubushyuhe bwiza buturuka kumugezi wa gazi uhindagurika hamwe nimirasire yubushyuhe bwamashyiga yaka inkuta zimbere.
Uburyo bwo Kubikoresha:
Ihagarikwa ryibanze rigomba kuba rirerire bihagije kugirango flame yaka ihuze hejuru yumutwe. Nibyiza niba hejuru yikibanza kiri hejuru kurenza gutwika. Icyo udashaka nukugira urumuri rugonga impande zoroheje zingenzi. Biremewe kandi niba urumuri rwakubise igice kinini cyo hasi cyibanze kuko iki gice nticyoroshye kwambara gaze.
Shandong Zhongpeng Special Ceramics Co., Ltd nimwe mubisubizo binini bya silicon karbide ceramic ibisubizo bishya mubushinwa. Ceramic tekinike ya SiC: Gukomera kwa Moh ni 9 (Gukomera kwa Moh ni 13), hamwe no kurwanya isuri no kwangirika, kwangirika kwiza - kurwanya no kurwanya okiside. Ubuzima bwa serivisi ya SiC ni inshuro 4 kugeza kuri 5 kurenza 92% bya alumina. MOR ya RBSiC yikubye inshuro 5 kugeza kuri 7 za SNBSC, irashobora gukoreshwa muburyo bukomeye. Igikorwa cyo gusubiramo cyihuta, gutanga ni nkuko byasezeranijwe kandi ubuziranenge ni ubwa kabiri kuri kimwe. Buri gihe dukomeza gutsimbarara ku ntego zacu no gusubiza imitima yacu muri sosiyete.
