Amatafari meza yo gushyushya amatanura ya AOD - Ubwoko, inyungu n'uburyo akoreshwa

Itanura rya AOD (Argon Oxygen Decarburization) ni ryo shingiro ry’ibikoresho by’ingenzi byo gukora ibyuma bitagira umugese n’ibyuma byihariye bya alloy. Ahantu ho gutunganya AOD harangwa n’ubushyuhe bwinshi cyane, ubushyuhe bwinshi, kwangirika gukomeye kw’ibishishwa bya alkaline, no kwangirika k’ibikoresho. Ibi bihe bikomeye byo gukora bituma amatafari atagira umugese ya AOD aba kimwe mu bintu by’ingenzi cyane ku nganda z’ibyuma. Guhitamo ubwoko bw’amatafari akwiriye atagira umugese byongera igihe cyo gukora icyuma, bigabanya ikiguzi cyo gusimbuza adafite umugese, kandi bikongera umusaruro muri rusange wo gukora ibyuma.

Niba ushaka ibisubizo biramba kandi bihendutse byo gushyiramo imiyoboro ya AOD, gusobanukirwa ubwoko bw'amatafari akoreshwa cyane ya AOD ni ingenzi. Hano turakwereka amatafari akoreshwa cyane kandi akora neza cyane yo gushyiramo imiyoboro ya AOD.

Amatafari ya magnesia chrome afatanye neza ni yo akoreshwa mu buryo busanzwe kandi bwizewe mu matanura ya AOD. Aya matafari akozwe mu matanura ya magnesia na chrome avanze neza binyuze mu gushyushya cyane, afite porosity nke, ubucucike bwinshi, kandi arwanya cyane slag. Arwanya neza isuri y'icyuma cya alkaline ndetse n'ubushyuhe bwinshi, ibi bikaba bikunze kugaragara mu gutunganya AOD. Ni meza cyane ku myanya y'ingenzi ikoreshwa cyane harimo umurongo wa AOD slag, agace ka tuyere n'agace k'inkuta zo ku ruhande, aya matafari arwanya slag akumira neza slag no kwangirika kw'agace k'inkuta.

Amatafari ya kalisiyumu ya Magnesia, azwi kandi nka dolomite refractory, yabaye amahitamo azwi cyane yo kubungabunga ibidukikije aho gukoresha amatafari ya kalisiyumu ya magnesia. Ayo matafari nta chromium ihumanya, afite imbaraga nziza cyane mu bushyuhe bwinshi kandi arwanya alkaline slag. Igice cya kalisiyumu oxyde gishobora kwinjiza sulfur n'imyanda mu byuma bishongeshejwe, bigatuma ubwiza bw'icyuma kidashonga burushaho kwiyongera. Abakora aya matafari benshi bayashyira ku byuma bishongeshejwe bya AOD, ku nkuta zihoraho n'imbere, bityo bikaba bihuye neza n'ibikorwa by'igihe kirekire byo gukora ibyuma.

Amatafari ya magnesia arangwa n'ubushyuhe bwinshi yagenewe uturere tw'amatanura ya AOD tudashyuha cyane kandi tudashyuha cyane. Afite umwanda muke cyane kandi afite imiterere mito, atanga imbaraga zidasanzwe za mekanike no kudashyuha cyane. Aya matafari arangwa n'ubushyuhe buhendutse akoreshwa cyane mu bikoresho byo hejuru by'amatanura no mu byuma by'inyongera, atanga uburinzi buhamye kandi bugabanya ishoramari ry'ibikoresho birwanya ubushyuhe muri rusange.

Kuki twahitamo amatafari yacu ya AOD Refractory yabigize umwuga?

Nk'umwuga mu gukora amatafari arwanya ubushyuhe muri AOD, tugenzura cyane uburyo ibikoresho fatizo bitoranywa n'uburyo bikorerwa. Amatafari yacu yose arwanya ubushyuhe mu itanura afite ubushobozi bwo kurwanya ubushyuhe bwinshi, imikorere yayo irwanya ingese kandi amara igihe kirekire. Dutanga amatafari arwanya ubushyuhe asanzwe kandi yihariye kugira ngo ahuze n'uburyo butandukanye bwo gukora mu matanura ya AOD n'inganda. Ibicuruzwa byacu bifasha inganda z'ibyuma kugabanya igihe cyo kudakora kw'ibikoresho, kugabanya ikiguzi cyo kubungabunga no kongera inyungu mu musaruro.

Ibitekerezo bya nyuma

Amatafari ya AOD akoreshwa mu bice bitandukanye akeneye ibikoresho by'amatafari bihuye. Amatafari ya Magnesia chrome, amatafari ya dolomite n'amatafari ya magnesia afite isuku nyinshi akubiyemo ibisabwa byose byo gukora no guhoraho mu bukorikori bwa AOD. Kubindi bikoresho by'amatafari ya AOD afite ireme kandi akoreshwa mu ruganda, twandikire kugira ngo ubone ibiciro byihariye n'ubuyobozi bw'umwuga.
