Mu nganda aho ubushyuhe bukabije ari ikibazo gihoraho, guhitamo ibikoresho byangiritse birashobora gukora cyangwa guhagarika imikorere, umutekano, no gukoresha neza. Amabuye maremare ya alumina igaragara nkibikoresho byibanze, byakozwe kugirango bihangane nubushyuhe bwo hejuru budashira, isuri yimiti, hamwe nubukanishi. Waba uri muri metallurgie, ceramics, gukora ibirahure, cyangwa urwego urwo arirwo rwose rusaba guhuza ubushyuhe, iyi minisiteri yihariye itanga imikorere ntagereranywa muburyo rusange bushobora kudahuza. Reka dushakishe impamvu minisiteri ya alumina yo mu bwoko bwa minisiteri aribwo buryo bwo hejuru bwo guhitamo ubushyuhe bwo hejuru cyane ku isi.
Mbere na mbere, minisiteri ya alumina yo mu bwoko bwa minisiteri iruta iyindi mikoreshereze ya metallurgjiya, umurenge aho ubushyuhe bukunze kuzamuka hejuru ya 1500 ° C. Mu ruganda rukora ibyuma, rukoreshwa cyane muguhuza amatafari yangiritse mumatanura yaturika, ingoyi, tundishing, hamwe nitanura ryamashanyarazi. Ibirungo byinshi bya alumina (mubisanzwe 70% kugeza 90%) birayiha imbaraga zidasanzwe, birinda gushonga cyangwa guhinduka nubwo haba hari ubushyuhe bukabije bwibyuma bishongeshejwe. Byongeye kandi, irwanya ruswa ituruka ku gishishwa cyashongeshejwe, okiside yicyuma, nibindi bintu bikaze bikunze gukorwa mubyuma. Uku kuramba kugabanya igihe cyatewe no kunanirwa kwanga, kwemeza imikorere ikomeza no kugabanya amafaranga yo gufata neza kubakora ibyuma.
Inganda zububumbyi n’ibirahure nazo zishingiye cyane kuri minisiteri yo hejuru ya alumina. Amatanura ya Ceramic, akoreshwa mu gucana ububumbyi, amabati, hamwe n’ubutaka bwiza, bukora ku bushyuhe buri hagati ya 1200 ° C na 1800 ° C. Amabuye maremare ya alumina atanga umurongo ukomeye, ushyushye-ushyushye kugirango uhindurwe neza muri ayo matanura, ukomeza ubusugire bwimiterere ndetse no mugihe cyo gushyushya no gukonjesha. Ku itanura ryo gushonga ibirahure, aho ubushyuhe burenze 1600 ° C, minisiteri irwanya ihungabana ryumuriro ni ngombwa. Irinda gucikamo no gutemba biterwa nihindagurika ryubushyuhe bwihuse, byongerera igihe cyo gutanura itanura no kwemeza ubuziranenge bwikirahure. Bitandukanye na minisiteri yo hasi ya alumina, ntabwo ikora hamwe no gushonga kw'ibirahure, birinda kwanduza bishobora kwangiza ibice byibirahure.
Ubundi buryo bwingenzi bukoreshwa mububiko bwa peteroli nubushyuhe. Mu byotsa, gutwika, hamwe no kuvugurura, alumina yo hejuru ya minisiteri yububiko bwa minisiteri yububiko bugabanya ubushyuhe bwinshi, imyuka ya flue, nigitero cyimiti ituruka kubicanwa nibicuruzwa. Mu mashanyarazi akoreshwa n’amakara, irwanya imiterere yangiza ivu ryisazi ningaruka zangiza za okiside ya sulfuru. Muri peteroli ya chimique nabavugurura, irwanya iyangirika rya hydrocarbone hamwe nubushyuhe bwo hejuru, bigatuma umusaruro utanga ingufu kandi neza. Ibikoresho byiza cyane byo gufatira hamwe nabyo bituma biba byiza gusana ibyangiritse byangiritse, kugabanya igihe cyo kugabanya no kongera igihe cya serivisi yibikoresho bikomeye.
Kurenga izo nganda zingenzi, minisiteri nini ya alumina yangiza isanga ikoreshwa munganda zitwika imyanda, aho ikemura ubushyuhe bwinshi hamwe na gaze yangirika iterwa no gutwika imyanda ya komini ninganda. Ni ngombwa kandi mu bishingwe byo gutondekanya ibishushanyo hamwe n'umusaraba ukoreshwa mu guta ibyuma. Ubwinshi bwarwo, bufatanije nubushyuhe bwo hejuru bwokwirinda no kuramba, bituma bukemurwa kwisi yose kubisabwa byose bisaba guhuza kwizewe mubidukikije bikabije.
Iyo uhisemo alumina yohanagura ya minisiteri, ni ngombwa guhitamo ibicuruzwa byiza-byujuje ubuziranenge bwinganda. Shakisha minisiteri hamwe nubunini buringaniye bwo gukwirakwiza, gukomera gukomeye, hamwe no guhangana nubushyuhe bwiza. Amabuye maremare ya alumina yamashanyarazi yakozwe hifashishijwe ibikoresho fatizo byubuhanga hamwe nubuhanga buhanitse bwo gutunganya, byemeza ko bitanga imikorere idasanzwe mubisabwa cyane. Waba ukeneye gutondekanya itanura rinini ryicyuma, gusana itanura ryibumba, cyangwa kubungabunga uruganda rukora amashanyarazi, minisiteri yacu itanga kwizerwa no kuramba ukeneye kugirango ibikorwa byawe bigende neza.
Ntukemere kumikorere iyo bigeze kubushyuhe bwo hejuru. Hitamo minisiteri ndende ya alumina kugirango irwanye ubushyuhe burenze, irwanya ruswa, kandi iramba. Twandikire uyu munsi kugirango umenye byinshi kubicuruzwa byacu nuburyo bishobora kuzamura imikorere yawe no kugabanya amafaranga yo kubungabunga.
