Amatafari y'icyuma gishyushye
Amatafari y'icyuma gitembareba amatafari adafite uburibwe ashyirwa mu miyoboro y'isahani yo hasi y'icyuma gicanwamo ingot kugira ngo ahuze amatafari y'icyuma atemba n'ibumba rya ingot, rizwi cyane nka runner brick. Akoreshwa cyane cyane mu kugabanya ubukana bw'icyuma gishongeshejwe no gukumira amazi ava mu cyuma. Ibintu by'ingenzi biranga birimo ubushyuhe bwinshi, ubukana bw'ingufu, ubukana bwiza bwo gutemba, uburyo bworoshye bwo gushyiraho no kurwanya umuriro neza.
1. Gushyira mu byiciro hakurikijwe ibikoresho:
Ibumba: (1)Ubu ni bwo bwoko bw'amatafari y'icyuma gikoreshwa mu byuma bito, akozwe mu ibumba risanzwe. Nubwo igiciro kiri hasi, ntabwo arwanya umuriro kandi nta gihe akoreshwa, kandi akwiriye inganda nto z'icyuma cyangwa izikoreshwa by'igihe gito.
(2) Aluminiyumu nyinshi:Iri tafari ry'icyuma gitemba rifite aluminium nyinshi, rishobora kurwanya umuriro neza, kandi rishobora kuguma mu buryo buhamye mu bushyuhe bwinshi. Rikunze gukoreshwa mu bigo binini by'ibyuma, cyane cyane mu bikorwa byo gukora ibyuma bikenera kwihanganira ubushyuhe bwinshi igihe kirekire.
(3)Ubwinshi:Uduce duto tw’ubuso dufite ishusho y’urushinge dufite imiterere y’urusobe rw’amakuru, ishobora gukumira isuri iterwa n’icyuma gishongeshejwe. Ubu ni cyo gikoreshwa cyane.
2. Gushyira mu byiciro hakurikijwe imikorere:
(1) Amatafari yo hagati
Ikoreshwa mu gice cy'imbere cy'icyuma gishongeshejwe, ishyigikira inzira y'amazi kandi isaba ubwinshi
gucika intege no kurwanya isuri.
(2) Amatafari yo kugabanya ibyuma
Ikoreshwa mu kuyobya icyuma gishongeshejwe kikajya mu bikoresho bitandukanye. Ibisobanuro bisanzwe birimo imyobo ibiri, itatu, n'imene, bitewe n'ibisabwa mu buryo.
(3) Amatafari y'umurizo
Biherereye ku mpera y'uburyo bw'icyuma gitemba, bihangana n'ingaruka z'icyuma gishongeshejwe n'ubushyuhe bwinshi kandi bisaba ubudahangarwa bwo kuvunika.
1. Ubudahangarwa bw'ubushyuhe bwinshi cyane
Zishobora kwihanganira ubushyuhe bukabije bwa 1500–1700℃ bw'icyuma gishongeshejwe igihe kirekire. Urugero, amatafari acukurwa ashingiye kuri mullite afite ubushobozi bwo kutarenza 1780℃, bigatuma akoreshwa mu gucukurwa mu bushyuhe bwinshi.
2. Ubudahangarwa bukomeye bwo kurwanya isuri
Kubera ko amatafari yubatswe mu buryo bunini kandi bukomeye, ashobora kurwanya gushwanyaguzwa n’icyuma gishongeshejwe mu buryo bwihuta, bigagabanya kwangirika no kwangirika mu gihe cyo kuyakoresha.
3. Ubudahangarwa bwiza bwo kwangirika
Zishobora kwihanganira isuri ya shimi iturutse ku byuma bishongeshejwe n'ibintu bitandukanye bishongeshejwe. Uburyo butandukanye bwo gukora ibintu bukoreshwa mu buryo bwihariye.
4. Ubudahangarwa bwiza bw'ubushyuhe
Zishobora kwihanganira ihindagurika ryihuse ry'ubushyuhe mu gihe cyo gucukura nta gucika cyangwa ngo zivunike.
5. Umwandu muke ku byuma bishongeshejwe
Imiterere y’ibikoresho byinshi igabanya gushishwa no gushwanyagurika kw’uduce, birinda ko imyanda yinjira mu cyuma gishongeshejwe kandi bigaha agaciro ubuziranenge n’ubwiza bw’ibikoresho bya nyuma by’icyuma.
6. Ubuziranenge buhamye bw'ibipimo
Zifite imiyoboro y'imbere yoroshye, imiterere isanzwe yo hanze, n'ubushobozi bwo kwihanganira ibintu mu buryo buhamye. Ibi bituma habaho guhuza neza mu gihe cyo gushyiraho, bigabanya ubushobozi bwo kwirinda gutemba kw'icyuma gishongeshejwe, kandi bikarinda ibyago byo gusohoka kw'icyuma.

Amatafari y'icyuma gitembazikoreshwa cyane cyane mu gucukura hasi, zigakoreshwa nk'umuyoboro w'icyuma gishongeshejwe gituruka ku gikombe kijya ku bibumbano bya ingot, bigatuma icyuma gishongeshejwe gikwirakwira neza kuri buri gibumbano cya ingot.
Imikorere y'ibanze
Amatafari y'icyuma anyura imbere mu mwobo, atuma icyuma gishongeshejwe gitembera mu cyerekezo, kikarinda ko gikora ku buryo butaziguye ku bimera bya ingot no kugabanya kwangirika kw'imiterere guterwa no gushyuha cyane. Byongeye kandi, imiterere yabyo yo kugabanya imbaraga ibafasha kwihanganira ingaruka zifatika n'ingaruka za shimi z'icyuma gishongeshejwe gishyushye cyane, bikarinda imyanda kwinjira mu cyuma no kugira ingaruka ku bwiza bwacyo.
Shandong Robert New Material Co., Ltd.iherereye mu Mujyi wa Zibo, mu Ntara ya Shandong, mu Bushinwa, ikaba ari ikigo gikoreramo ibikoresho birwanya ubukana. Turi ikigo kigezweho gihuza ubushakashatsi n'iterambere, umusaruro, kugurisha, igishushanyo mbonera n'ubwubatsi bw'itanura, ikoranabuhanga, no kohereza mu mahanga ibikoresho birwanya ubukana. Dufite ibikoresho byuzuye, ikoranabuhanga rigezweho, imbaraga zikomeye mu bya tekiniki, ubwiza bw'ibicuruzwa, n'izina ryiza. Uruganda rwacu rukora hegitari zirenga 200 kandi umusaruro w'ibikoresho birwanya ubukana buri mwaka ni toni 30000 naho ibikoresho birwanya ubukana ni toni 12000.
Ibikoresho byacu by'ingenzi bikozwe mu bikoresho birwanya ubushyuhe birimo:ibikoresho birwanya alkaline; ibikoresho birwanya silikoni ya aluminiyumu; ibikoresho birwanya imiterere idashushanyije; ibikoresho birwanya ubushyuhe; ibikoresho byihariye birwanya imikorere; ibikoresho birwanya imikorere yo gukoresha mu gucukura bidasibangana.
Ibibazo Bikunze Kubazwa
Ukeneye ubufasha? Menya neza ko usura urubuga rwacu rw'ubufasha kugira ngo uhabwe ibisubizo by'ibibazo byawe!
Turi uruganda nyakuri, uruganda rwacu rwihariye mu gukora ibikoresho birwanya ubushyuhe mu gihe kirenga imyaka 30. Twizeza gutanga igiciro cyiza, serivisi nziza mbere yo kugurisha no nyuma yo kugurisha.
Kuri buri gikorwa cyo gukora, RBT ifite sisitemu yuzuye ya QC y’imiterere ya chimique n’imiterere ifatika. Kandi tuzagerageza ibicuruzwa, kandi icyemezo cy’ubuziranenge kizatangwa hamwe n’ibicuruzwa. Niba ufite ibisabwa byihariye, tuzagerageza uko dushoboye kose kugira ngo tubigereho.
Bitewe n'ingano, igihe cyo kohereza kiratandukanye. Ariko twizeza kohereza vuba bishoboka kandi bifite ubuziranenge bwemejwe.
Birumvikana ko dutanga ingero ku buntu.
Yego, birumvikana ko mufite ikaze gusura ikigo cya RBT n'ibicuruzwa byacu.
Nta mupaka uhari, dushobora gutanga igitekerezo cyiza n'igisubizo gikwiye bitewe n'imimerere yawe.
Tumaze imyaka irenga 30 dukora ibikoresho birwanya ubushyuhe, dufite ubufasha bukomeye mu bya tekiniki n'uburambe bwinshi, dushobora gufasha abakiriya gushushanya amatanura atandukanye no gutanga serivisi imwe.
