ikoreshwa mu itanura ry'inganda
Iki gicuruzwa ni cyiza cyane mu itanura, gushonga, gushongesha kandi gikoreshwa ku bicuruzwa by'ubwoko bwose. Mu rwego rw'inganda zikora imiti, peteroli no kurengera ibidukikije hamwe n'uburyo butandukanye bwo kubikoresha.
1) Guhagarara neza kw'ubushyuhe
2) imiti irwanya ingese
3) Ihangana n'ubushyuhe bwinshi (kugeza kuri 1650°
4) Irwanya kwangirika/kwangirika/okiside
5) Ingufu za mekanike zikora neza cyane
6) Gusukura cyangwa gukata ubuso bugoye cyane bwo munsi y'ubutaka
7) Ikoreshwa mu gusya, gufunga no gukata insinga ndetse no gutwika ibintu bikaze

Igikoresho cyo gushushanya ni inkono y'ibumba ikoreshwa mu kubika icyuma cyo gushongesha mu itanura. Iki ni igikoresho cyo gushushanya cy’ubwoko bwiza kandi cyo mu rwego rw’inganda gikoreshwa n’inganda zikora imitako mu bucuruzi.
Icyo Ikora:
Igikoresho cyo gushongesha kirakenewe kugira ngo gihangane n'ubushyuhe bukabije bugaragara mu byuma bishongesha. Igikoresho cyo gushongesha kigomba kuba gifite ubushyuhe bwinshi kurusha ubw'icyuma gishongesha kandi kigomba kuba gifite imbaraga nyinshi nubwo cyaba gishyushye cyane.
Birashoboka gukoresha icyuma gishongesha ibyuma mu rugo kugira ngo ushongeshe ibyuma nka zinc na aluminiyumu, kuko ibyo byuma bishongesha ku bushyuhe buri munsi cyane y’icyuma. Ariko gupima (gushonga) ubuso bw’imbere bw’icyuma gishongesha ibyuma ni ikibazo. Iki gipimo gishobora kwanduza ishonga no kugabanya inkuta z’icyuma vuba. Ibikoresho bishongesha ibyuma bizagufasha niba ugitangira kandi nta kibazo ufite cyo guhangana n’icyo gipimo.
Ibikoresho bikunze gukoreshwa mu kubaka ibikoresho byo mu bwoko bwa "crucible" ni ibumba-grafiti, na silicon-carbide iboheshejwe na karuboni. Ibi bikoresho bishobora kwihanganira ubushyuhe bwinshi mu mirimo isanzwe yo kubumba. Silicon carbide ifite inyungu yo kuba ibikoresho biramba cyane.
Ibikoresho byacu bya Clay Graphite Bilge Shape bifite ubushyuhe bwa 2750 °F (1510 °C). Bizakoresha zinc, aluminium, umuringa / bronze, ifeza na zahabu. Uruganda ruvuga ko bishobora gukoreshwa mu byuma bishongeshejwe. Byakorewe muri Leta Zunze Ubumwe za Amerika!
Imiterere y'Urusenda:
Igikoresho cy'ubugari gifite ishusho ya "bilge" (“B” Shape) gisa n'agacupa ka divayi. Ingano ya "bilge" ni umurambararo w'igikoresho cy'ubugari aho cyagutse cyane. Niba nta murambararo wa bilge ugaragara, umurambararo wo hejuru ni wo murambararo ntarengwa.
Itegeko rigenga ibintu rivuga ko # y'icyuma gikoreshwa mu gutwika gitanga ubushobozi bwo gukora mu biro bya aluminiyumu. Ku mucuzi cyangwa umuringa, ikoreshwa inshuro eshatu z'icyuma gikoreshwa mu gutwika #. Urugero, #10 icyuma gikoreshwa mu gutwika cyashoboraga gutwara ibiro bigera kuri 10 bya aluminiyumu n'ibiro 30 by'umuringa.
Ibikoresho byacu bifite ishusho ya "B" bikunze gukoreshwa n'abantu bakunda gukoresha ibikoresho byo mu bwoko bwa "pop" ndetse n'abakunda gukoresha ibikoresho byo mu bwoko bwa "casters". Ibi ni ibikoresho byiza kandi biramba mu bucuruzi.
Reba imbonerahamwe ziri hepfo kugira ngo umenye ingano ikwiriye akazi kawe.
Uburyo bwo kuyikoresha:
Ibikoresho byose bigomba gufatwa n'udukoni dufata neza (igikoresho cyo guterura). Ibikoresho bidakwiye bishobora kwangiza cyangwa guhomba burundu mu gihe kibi gishoboka.
Disiki y'ikarito ishobora gushyirwa hagati y'icyuma gishyushya n'ishingiro ry'itanura mbere yo gushyushya. Ibi bizashya, bigasiga urwego rwa karuboni hagati yabyo kandi bikabuza icyuma gushyushya gufata hasi mu itanura. Igitwikirizo cya Plumbago (Carbon Black) gikora nk'ibyo.
Ni byiza gukoresha icyuma gishya gitandukanye kuri buri bwoko bw'icyuma kugira ngo wirinde kwanduzanya. Nanone menya neza ko wakuyemo burundu icyuma gishya nyuma yo kugikoresha. Icyuma gisigaye kugira ngo gikomere mu cyuma gishobora kwaguka mu kongera gushyushya no kugisenya.
Shyira icyuma gishya cyangwa ibyari bibitswe. Shyushya icyuma gishya mu masaha 2 kuri 220 F (104 C). (Koresha umwuka uhagije. icyuma gishya kizapfuka umwotsi uko glaze itangiye.) Hanyuma shyira icyuma gishya ku muriro utukura. Reka icyuma gikonje kugeza ku bushyuhe bw'icyumba mu itanura mbere yo gukoresha. Ubu buryo bugomba gukurikizwa ku bikoresho bishya BYOSE ndetse no ku bikoresho byose bishobora kuba byarahuye n'ubushuhe mu bubiko.
Bika ibikoresho byose by'ibumba ahantu humutse. Ubushuhe bushobora gutuma ibikoresho by'ibumba bicika iyo bishyushye. Niba bimaze igihe bibitswe, ni byiza kongera kubikoresha.
Ibikoresho bya silikoni bya karubide ni byo bishobora kunyunyuza amazi mu bubiko kandi akenshi ntibikenera gushyuha mbere yo kubikoresha. Ni byiza gutwika ibikoresho bishya ku muriro utukura mbere yo kubikoresha bwa mbere kugira ngo bikureho kandi bikomereze ibipfukisho byo mu ruganda.
Ibikoresho bigomba gushyirwa mu cyuma cyo gutwika mu buryo bworoshye cyane. NTUKIGERE "upakira" icyuma cyo gutwika mu cyuma, kuko ibikoresho bizakura mu gihe gishyushye kandi bishobora kwangiza ibumba. Iyo iki gikoresho kimaze gushonga kikavamo "agatsinsino", shyiramo ibindi bikoresho witonze mu kidendezi kugira ngo bishonge. (UMUBURO: Niba hari ubushuhe ku gikoresho gishya, hazaduka umwuka ushyushye). Ongera ushyire mu cyuma neza. Komeza ushyiremo ibikoresho mu cyuma kugeza igihe igipimo gikenewe kishongeshejwe.
UMUBURO!!!: Ibikoresho byo mu bwoko bwa Crucibles biteje akaga. Gushongesha ibyuma mu kintu cyo mu bwoko bwa Crucible biteje akaga. Gusuka ibyuma mu bibumbano biteje akaga. Ibikoresho byo mu bwoko bwa Crucibles bishobora kwangirika nta nteguza. Ibikoresho byo mu bwoko bwa Crucibles bishobora kuba birimo inenge zihishe mu bikoresho no mu nganda zishobora gutuma ibintu binanirana, kwangirika kw'umutungo, gukomeretsa umuntu, gukomeretsa ababireba no kubura ubuzima.
Ishingiro ry'Ibyuma Bishobora Kubazwa
Ibisobanuro:
BCS Ishingiro ni inkingi y'ubushyuhe bwinshi ikoreshwa mu kuzamura icyuma gishyushya mu itanura.
Icyo Ikora:
Ibyuma by'ibanze bikunze gukoreshwa mu itanura rikoresha gaze kugira ngo bizamure ibyuma by'umuriro kugira ngo umuriro w'umuriro udahita ugwa mu rukuta rworoshye rw'ibyuma by'umuriro. Iyo umuriro w'umuriro wemerewe gukubita ibyuma by'umuriro bishobora gutuma urukuta rw'ibyuma by'umuriro rugwa nabi bityo bikamara igihe gito. Uburyo bwiza bwo kwirinda ibi ni ugukoresha ibyuma by'ibanze kugira ngo uzamure ibyuma by'umuriro bivane mu gace k'ibyuma by'umuriro.
Guterura icyuma gishyushya binatuma kiba mu "gace k'ubushyuhe" k'itanura. Nubwo urumuri rw'umuriro rwinjiye mu mubiri w'itanura hepfo, agace gashyushye cyane ni kuva hagati kugera hejuru. Ni muri ako gace inkuta z'itanura zishyushywa neza na gaze izenguruka. Kugira impande z'icyuma gishyushya muri aka gace bituma habaho ubushyuhe bwiza buturutse ku mugezi wa gaze uhindagurika ndetse n'imirasire y'ubushyuhe bw'inkuta z'imbere z'itanura.
Uburyo bwo kuyikoresha:
Ibyuma by'ibanze bigomba kuba birebire bihagije kugira ngo urumuri rw'umuriro ruhuzwe n'igice cyo hejuru cy'ibyuma. Nta kibazo niba igice cyo hejuru cy'ibyuma kiri hejuru y'aho icyuma gicana. Icyo udashaka ni uko urumuri rukubita impande zoroshye z'ibyuma. Biremewe kandi niba umuriro ukubita igice cyo hasi cy'ibyuma kuko iki gice kidapfa kwangirika kubera umwuka.
Shandong Zhongpeng Special Ceramics Co., Ltd ni imwe mu mashami manini ya silicon carbide ceramic mu Bushinwa. SiC technical ceramic: Ubukana bwa Moh ni 9 (Ubukana bwa Moh bushya ni 13), bufite ubudahangarwa bwiza bwo kwangirika no kwangirika, ubukana bwiza bwo kwangirika no kurwanya oxidation. Igihe cy'akazi k'ibicuruzwa bya SiC ni inshuro 4 kugeza kuri 5 ugereranyije n'ibikoresho bya alumina 92%. MOR ya RBSiC ikubye inshuro 5 kugeza kuri 7 ugereranyije na SNBSC, ishobora gukoreshwa mu miterere igoye cyane. Uburyo bwo gutanga ibiciro ni bwihuse, gutanga ibintu ni uko byasezeranijwe kandi ubwiza ni ubwa mbere. Buri gihe dukomeza guhangana n'intego zacu kandi tugasubiza imitima yacu kuri sosiyete.
