Amatafari yoroheje y’ibumba Amatafari akozwe mubumba ryibumba ryumuriro nkibikoresho fatizo nibumba bya pulasitike nkibikoresho bihuza hanyuma ukongeramo ibikoresho bishobora gutwikwa cyangwa kubira ifuro binyuze mu kurasa. Ibumba ryibumba ryibumba bigaragara ko ari ryinshi 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 ubwiza bwibikoresho byubushyuhe.
Amatafari yoroheje yibumba Amatafari akorwa mubumba ryinshi ryumuriro wibumba na binder, mugucumura mubushyuhe bwinshi. ibumba ryibumba ryibumba nigiciro gito cyo kwanga amatafari hamwe nibikorwa byiza. Ibyiza byingenzi byo guhagarika ibumba ni ukunanirwa gukabije munsi yumutwaro, coefficient zo kwagura umurongo muto, guhangana nubushyuhe bwiza bwumuriro hamwe 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 cy’igihugu giheruka, kikaba gifite n’ubucucike bwinshi, imbaraga nyinshi, ubushyuhe buke bw’umuriro n’umwanda muke.
Firebrick yibumba ryibicuruzwa nibicuruzwa bifite 30 ~ 40% bya Al2O3. ikaba ikozwe muri 50% ibumba ryoroshye na 50% chamotte ikurikije granulaitike ikeneye kuvanga no kurasa kuri 1300 ~ 1400 temperature ubushyuhe bwinshi nyuma yo kubumba no gukama. Ibumba ryibumba ryamatafari yamabuye yingenzi arimo kaolinite (Al2O3 · 2SiO2 · 2H2O) hamwe n’umwanda wa 6 ~ 7% (K, Na, Ca, Ti, Fe oxyde).

Inzira yo kubumba ibumba ikoreshwa cyane cyane mugukingira hejuru yubushyuhe cyangwa gushyigikira ubushyuhe bwibindi bikoresho byangiritse. Ibikoresho byangiritse cyangwa ibikoresho bitanga ubushyuhe bwinganda, nka, itanura rya Ethylene pyrolysis, itanura ya tubular, kuvugurura itanura rya ammonia synthique, generator ya gaz hamwe nubushyuhe bwo hejuru bwa shullte, nibindi.
