Amatafari yo mu ifuru izunguruka ya sima: Ubwoko n'ikoreshwa ryayo

Amatanura azunguruka ya simani ibikoresho by'ingenzi mu gukora sima, bikorera mu bihe bikomeye cyane—ubushyuhe bugera kuri 1450°C, isuri ikomeye ya shimi ituruka ku byuma bya alkaline na clinker, hamwe no kwangirika guhoraho kwa mashini. Guhitamo amatafari akwiye ni ingenzi kugira ngo imikorere ihamye ikore, kongera igihe cyo gukoresha itanura, no kugabanya ikiguzi cyo kuribungabunga. Hasi hari ubwoko bw'ingenzi bw'amatafari akoreshwa ku matanura ya sima, buri rimwe rigenewe ahantu runaka ho gukorera.

Amatafari ya alumina menshini yo matafari akoreshwa cyane mu matanura azunguruka ya sima. Afite alumina iri hagati ya 48% na 75%, afite ubushobozi bwo guhangana n'ubushyuhe bwinshi, ubushyuhe burakomera, kandi arwanya kwangirika cyane. Akoreshwa cyane cyane mu bice bidashyuha cyane nko mu ifuru, mu ishyushya rya mbere, no mu ifuru ribora, aho ubushyuhe buri hagati ya 800°C na 1200°C. Ubushyuhe buke bwazo butuma zirinda imyuka yangiza, bigatuma ziba nziza mu duce dufite isuri iringaniye.

Amatafari ya Spinel ya Magnesia-AluminaNi ingenzi cyane ku gace gatwikirwamo itanura, aho ubushyuhe bugera kuri 1350°C kugeza 1450°C. Bigizwe na magnesium oxyde na alumina, bifite ubushobozi bwo kurwanya ubushyuhe bwinshi kandi bishobora gukora urwego rwo kurinda iyo bihuye na clinker, birwanya neza isuri ya clinker ishongeshejwe. Ugereranyije n'amatafari ya magnesia-chrome, bifite ubushobozi bwo kurwanya spalling, bigatuma biba amahitamo akomeye mu turere dushyuha cyane.

Amatafari ya Magnesia-Chrome afatanye mu buryo butaziguyeZirakomeye mu kurwanya ingese. Zakozwe mu magnesite na chromite nziza, zigashyirwamo calcium kuri 1750-1850°C, zikwiriye ahantu hatwikwa n'ahantu hahinduka, aho isuri ya alkaline na sulfate iba ikomeye. Zitanga ubushyuhe bwinshi bworoshya imitwaro n'imbaraga nziza za mekanike, zituma zigumana umutekano igihe kirekire mu bidukikije bikomeye.

Amatafari arwanya alkalibyagenewe umuyoboro w’umwuka wa gatatu n’aho umuyaga utandukanya umuyaga, aho isuri y’umwuka wa alkali igaragara cyane. Hamwe na alumina iri hagati ya 25% na 30% na silica irenga 65%, bikora urwego rw’ubushyuhe bwinshi kugira ngo bizibire kwinjira kwa alkali, bikarinda amatafari gusenyuka no kwangirika.

Guhitamo amatafari akwiye akoreshwa mu itanura bigira ingaruka ku musaruro no ku giciro. Amatafari yacu akoreshwa mu gutunganya amatafari mato ahuye n'ibipimo ngenderwaho by'inganda, hamwe n'ibisubizo byihariye ku bwoko butandukanye bw'amatafari. Twandikire uyu munsi kugira ngo ubone ibikoresho byizewe bikoreshwa mu gutunganya amatafari mato bigabanya igihe cyo gukora amatafari kandi bikongera imikorere myiza yo gukora sima.
