Amatafari Yoroheje Yibumba Amatafari nubwoko bwibikoresho byo kwangirika byubwoko bwose bwamashyanyarazi yinganda hamwe nibintu byiza bitandukanye byimbaraga nyinshi, ndetse nubucucike bwinshi, ubushyuhe buke bwumuriro nubuhumane buke. Amatafari yumuriro wibumba yakozwe hamwe nibikoresho byo mu rwego rwo hejuru munsi yubushyuhe bwo hejuru ukurikije tekinoroji yacu yo gukora. Ikibumbano cyibumba kirashobora gukoreshwa mugushonga itanura, gutunganya ibikoresho, ibikoresho byo gushyushya, ibikoresho bishya, itanura rya gaz, urwobo rwogeramo, itanura rya annealing, ibindi bikoresho bishyushya inganda ninganda.

Ibiro Byoroheje Ibumba Kubumba Amatafari Ibisobanuro

Amatafari Yoroheje Yibumba Amatafari akozwe mubumba ryibumba ryumuriro nkibikoresho fatizo nibumba bya pulasitike nkibikoresho byo guhuza hanyuma ukongeramo ibikoresho bishobora gutwikwa cyangwa kubira ifuro binyuze mu kurasa. Ibumba ryibumba ryibumba bigaragara ko ari hejuru ya 40 ~ 85% naho ubwinshi bwikuba munsi ya 1.5 g / cm3. Amatafari yumuriro wibumba akoreshwa cyane nkibikoresho byo kubika mu itanura ryinganda kugirango bigabanye ubushyuhe bw itanura, bizigama ingufu kandi byorohereze ibikoresho byubushyuhe.

Ibyiza byumucyo wibumba ryibumba Amatafari

Urwego rwo hasi rwicyuma nibindi byanduye,
Kwanga cyane,
Umubyimba mwinshi, ubunini buke,
Ingaruka nziza yubushyuhe ningufu zikoreshwa,
Amashanyarazi meza atuje,
Kurwanya ruswa no kurwanya isuri.

Uburyo bwo Gukora Amatafari Yoroheje Ibumba Amatafari

Amatafari Yoroheje Ibumba Amatafari akorwa mubumba ryinshi ryumuriro wibumba na binder, mugucumita mubushyuhe bwinshi. Ibumba ryibumba ryibumba nigiciro gito cyo kugarura amatafari hamwe nibikorwa byiza. Ibyiza byingenzi byo guhagarika ibumba ni ukunanirwa kwinshi munsi yumutwaro, coefficient zo kwagura umurongo muke, kurwanya ubushyuhe bwumuriro nubushobozi bukomeye bwo kurwanya isuri. Bikaba bikozwe mu bikoresho byo mu rwego rwo hejuru byo mu rwego rwo hejuru munsi yubushyuhe bwo hejuru ukurikije igipimo cyigihugu giheruka, gifite nubucucike bwinshi, imbaraga nyinshi, ubushyuhe buke bwumuriro nubuhumane buke.

Ibigize urumuri ruremereye rwibumba Amatafari

Firebrick yibumba ryibicuruzwa nibicuruzwa bifite 30 ~ 40% bya Al2O3. ikaba ikozwe muri 50% ibumba ryoroshye na 50% ya chamotte ukurikije granularité ikenera kuvanga no kurasa kuri 1300 ~ 1400 temperature ubushyuhe bwo hejuru nyuma yo kubumba no gukama. Ibumba ryibumba ryibumba ryibumba ryibanze ririmo kaolinite (Al2O3 · 2SiO2 · 2H2O) hamwe na 6 ~ 7% byanduye (K, Na, Ca, Ti, Fe oxyde).
