Ubwoko 7 bwa Corundum Yangiza Ibikoresho Byibanze Bikoreshwa Mubisanzwe

01 S.intered Corundum
Corundum yacumuye, izwi kandi nka alumina yacumuye cyangwa igice cya kabiri cyashongeshejwe, ni clinker yangiritse ikozwe muri alumina yabazwe cyangwa alumina yinganda nkibikoresho fatizo, hasi mumipira cyangwa imibiri y'icyatsi, kandi igacumura mubushyuhe bwinshi bwa 1750 ~ 1900 ° C.

Alumina yacumuye irimo ibice birenga 99% bya aluminium oxyde ikozwe muri corundum imwe ihuriweho neza. Igipimo cy’ibyuka bihumanya ikirere kiri munsi ya 3.0%, ubwinshi bw’ubunini bugera kuri 3.60% / metero kibe, kuvunika bigera hafi yo gushonga kwa corundum, bifite ubwinshi bw’imiterere n’imiterere y’imiti ku bushyuhe bwinshi, kandi ntibishobora kwangirika mu kugabanya ikirere, ikirahure cyashongeshejwe nicyuma gishongeshejwe. , imbaraga zumukanishi no kwambara birwanya ubushyuhe busanzwe nubushyuhe bwo hejuru.

02Corundum
Corundum ikoreshwa ni corundum yubukorikori ikorwa no gushonga ifu ya alumina nziza mu itanura ryamashanyarazi ryinshi. Ifite ibiranga ahantu ho gushonga cyane, imbaraga za mashini nyinshi, guhangana neza nubushyuhe bwumuriro, kurwanya ruswa ikomeye hamwe na coefficient ntoya yo kwaguka. Coruseum ikoreshwa ni ibikoresho fatizo byo gukora ibikoresho byo mu rwego rwo hejuru bidasanzwe. Ahanini ushizemo corundum yera yahujwe, corundum yumukara, sub-cyera corundum, nibindi.

03Fused White Corundum
Corundum yera ikozwe mu ifu ya alumina yera kandi igashonga ku bushyuhe bwinshi. Yera mu ibara. Uburyo bwo gushonga corundum yera ahanini ni inzira yo gushonga no kongera gutunganya ifu ya alumina yinganda, kandi nta nzira yo kugabanya. Ibirimo Al2O3 ntabwo biri munsi ya 9%, kandi ibyanduye ni bito cyane. Ubukomere ni buto ugereranije na corundum yumukara kandi ubukana buri hasi gato. Akenshi bikoreshwa mugukora ibikoresho byangiza, ububumbyi bwihariye nibikoresho bigezweho.

04Fused Brown Corundum
Corundum yijimye ikozwe muri aluminium ya bauxite nkibikoresho nyamukuru kandi bivangwa na kokiya (anthracite), kandi bigashongeshwa mu itanura ry’amashanyarazi rifite ubushyuhe bwinshi ku bushyuhe buri hejuru ya 2000 ° C. Corundum yijimye ifite ibara ryinshi nubukomezi bwinshi kandi ikoreshwa kenshi mubutaka, gutondeka neza hamwe nibikoresho bigezweho.

05Sub-cyera Corundum
Subwhite corundum ikorwa na electromelting icyiciro cyihariye cyangwa bauxite yo mucyiciro cya mbere mugabanya ikirere nikirere kigenzurwa. Mugihe ushonga, ongeramo kugabanya ibintu (karubone), gutuza (ibyuma byuma) hamwe na decarburizing agent (igipimo cyicyuma). Kuberako imiterere yimiti nibintu bifatika byegeranye na corundum yera, yitwa sub-cyera corundum. Ubwinshi bwacyo buri hejuru ya 3.80g / cm3 kandi bigaragara ko ububobere buri munsi ya 4%. Nibikoresho byiza byo gukora ibikoresho bigezweho byo kwangirika nibikoresho bidashobora kwambara.

06Chrome corundum
Hishimikijwe corundum yera, hiyongereyeho 22% chromium, kandi ikorwa no gushonga mu itanura ryamashanyarazi. Ibara ni umutuku-umutuku. Ubukomezi buri hejuru gato ya corundum yijimye, isa na corundum yera, kandi microhardness irashobora kuba 2200-2300Kg / mm2. Ubukomezi buri hejuru yubwa corundum yera kandi munsi gato ugereranije na corundum yumukara.

07Zirconium Corundum
Zirconium corundum ni ubwoko bwa corundum yubukorikori ikozwe mu gushonga alumina na okiside ya zirconium ku bushyuhe bwinshi mu itanura ry’amashanyarazi, korohereza, gukonjesha, kumenagura no gusuzuma. Icyiciro nyamukuru cya kirisiti ya zirconium corundum ni α-Al2O3, icyiciro cya kabiri cya kirisiti ni baddeleyite, kandi hariho n'akantu gato k'ikirahure. Imiterere ya kristu nuburyo bwa zirconium corundum nibintu byingenzi bigira ingaruka kumiterere yabyo. Zirconium corundum ifite ibiranga ubukana bwinshi, ubukana bwiza, imbaraga nyinshi, imiterere yuzuye, imbaraga zo gusya, imiti ihamye, hamwe no guhangana nubushyuhe bwiza. Ikoreshwa cyane mubikorwa byo gukuramo ibikoresho no kuvunika. Ukurikije ibice bya okiside ya zirconium, irashobora kugabanywa mubice bibiri byibicuruzwa: ZA25 na ZA40.
