Ubudahangarwa n'ubushyuhe bwinshi, Ubucucike bw'umubiri bunini, Amazi make anyobwa, Ubushyuhe buto bwo kwaguka buvanze na coefficient fused spinel

  • Umugongo wa manyeziyumu aluminati
  • Spinel ya magnesium aluminate ivanze
  • Spinel ifite isuku nyinshi

Ibisobanuro bigufi

Spinel ivanze ni igihingwa cya magnesia-alumina gifite isuku nyinshi, gikorwa binyuze mu guhuza magnesia na alumina mu itanura rya arc. Nyuma yo gukonjesha no gukonjesha, irashwanyaguzwa kandi igashyirwa mu byiciro ku buryo bukenewe. Ni kimwe mu bintu birwanya ubushyuhe bwinshi. Kubera ko ifite ubushyuhe buke, irangwa no kudahindagurika cyane mu bushyuhe no kudahindagurika, magnesia-alumina spinel ni ibikoresho fatizo birwanya ubushyuhe. Ifite ibara ryiza n'isura nziza, ubucucike bwinshi, kudahangana cyane no gukurwaho kw'amazi no kudahindagurika mu bushyuhe, bituma iki gicuruzwa gikoreshwa cyane mu itanura rizunguruka, igisenge cy'amatanura y'amashanyarazi, gushonga ibyuma n'ibyuma, itanura rizunguruka rya sima, itanura ry'ibirahure n'inganda zikora ibintu bitandukanye.


Uburyo bwo gukora no gushyira mu bikorwa

Yakozwe muri magnesia nziza cyane na alumina ikoreshwa muri Bayer mu itanura rinini ry’amashanyarazi. Ifite ubushobozi bwiza bwo kugabanya ubukana, kandi ishobora gukoreshwa mu gukora amatafari n’amatafari mu turere aho kurwanya ubukana ari ingenzi.

Nk'ibi bikurikira: Igisenge cya EAF n'itanura rya ogisijeni y'ibanze, Ikirahuri cy'icyuma, urwego rwo hagati rw'itanura rizunguruka rya sima, n'ibindi.

Ibiranga Umugongo Uvanze

Intangiriro y'ibicuruzwa:Spinel ya magnesia-aluminum ivanze ikozwe muri alumina yo mu rwego rwo hejuru ifite sodium nkeya, ifu ya magnesia ishyushye cyane kandi isukuye nk'ibikoresho fatizo, kandi ishongeshwa mu itanura ry'amashanyarazi rifite ubushyuhe buri hejuru ya 2000°C.

Ibiranga ibicuruzwa:Ubudahangarwa bw'ubushyuhe bwinshi, ubucucike bw'umubiri munini, amazi make, ubushyuhe buke bwo kwaguka, ubushyuhe bwiza butuje, ubudahangarwa bukomeye bwa corruption no kudashonga kw'amazi.

Ugereranyije n'uburyo bwo gusya mu gukora spinel, uburyo bwo gusya mu buryo bwa electrofusion bufite ubushyuhe bwinshi bwa calcination, bugera kuri 2000°C, bigatuma spinel iba nyinshi, ifite ubucucike bwinshi, kandi irwanya amazi. Uburyo bwo gusya bumeze nk'uburyo bwo gukora spinel.

Ibikoresho fatizo ahanini bikoresha alumina yo mu nganda n'ifu nziza ya magnesium oxide itwikwa n'urumuri.

Ikoreshwa ry'ibicuruzwa:Ikoreshwa cyane mu gushongesha ibyuma, igisenge cy'itanura ry'amashanyarazi, ikiyiko, itanura rizunguruka rya sima, itanura ry'inganda z'ibirahure n'inganda zikora ibyuma, n'ibindi. Ni ibikoresho byiza byo gukora icupa rihoraho

amatafari yo ku rubura, amatafari yo ku rubura, amatafari yo ku rubura n'amatafari yo mu itanura ritambitse, hamwe na sima nini Ibikoresho by'ibanze byo mu matanura, amatafari yo ku rubura akoreshwa mu matanura aciriritse, amatafari yo ku rubura akoreshwa mu matanura n'amatafari yo mu itanura rishyushye cyane n'akoreshwa mu matanura ashyushye cyane.

Uburyo bwo gukora ibicuruzwa bya Spinel byahujwe

Umusaruro w’isosiyete ya fused aluminium magnesium spinel ufite urwego rwinshi, ukurikije ibisabwa n’abayikoresha, ingano y’uduce, ubugari bushobora gukorwa igihe cyose bikenewe.

ibicuruzwa bifitanye isano
