Ubwoko 7 bw'ibikoresho fatizo bya Corundum bikunze gukoreshwa mu bikoresho bishyushya

01 SCorundum ihuriweho
Sintered corundum, izwi kandi nka sintered alumina cyangwa semi-melten alumina, ni clinker ikora ikoresheje calcium cyangwa aluminium ikoze mu nganda nk'ibikoresho fatizo, igasya ikameramo udupira cyangwa imibiri y'icyatsi kibisi, hanyuma igashonga ku bushyuhe buri hejuru bwa 1750 ~ 1900°C.

Alumina ya Sintered irimo aside aluminiyumu irenga 99% igizwe ahanini na corundum ifite imiterere imwe ivanze neza. Igipimo cy'imyuka ihumanya kiri munsi ya 3.0%, ubucucike bw'ingano bugera kuri 3.60% kuri metero kibe, ubushobozi bwo gushonga buri hafi y'aho corundum ishongera, ifite ubushobozi bwo kudahindagurika neza mu bushyuhe bwinshi, kandi ntiyononekara bitewe no kugabanya ikirere, ikirahure gishongeshejwe n'icyuma gishongeshejwe. , imbaraga nziza za mekanike kandi idashobora kwangirika mu bushyuhe busanzwe n'ubushyuhe bwinshi.

02Corundum yahujwe
Corundum ivanze ni corundum y'ubukorano ikorwa no gushongesha ifu ya alumina mu itanura ry'amashanyarazi rishyushye cyane. Ifite imiterere yo gushonga cyane, imbaraga nyinshi za mekanike, ubudahangarwa bwiza bw'ubushyuhe, ubudahangarwa bukomeye bwa corruption na coefficient ntoya yo kwaguka. Corundum ivanze ni ibikoresho fatizo byo gukora ibikoresho byihariye birwanya corruption. Muri byo harimo cyane cyane corundum y'umweru ivanze, corundum y'umukara ivanze, corundum y'umweru, nibindi.

03Corundum Yera Ivanze
Korundumu yera ivanze ikorwa mu ifu ya alumina yonyine kandi igashongeshwa ku bushyuhe bwinshi. Ifite ibara ry'umweru. Uburyo bwo gushongesha korundumu yera muri rusange ni uburyo bwo gushongesha no kongera gukoresha ifu ya alumina yo mu nganda, kandi nta buryo bwo kugabanya. Ingano ya Al2O3 ntabwo iri munsi ya 9%, kandi ingano y'umwanda ni nto cyane. Ubukana bwayo ni buto gato ugereranyije na korundumu y'umukara kandi ubukana bwayo ni buke gato. Ikunze gukoreshwa mu gukora ibikoresho byo gukurura, ibumba ryihariye n'ibikoresho bigezweho byo gukurura.

04Corundum y'umukara yahujwe
Korundum y'umukara ivanze ikorwa muri bauxite ifite alumina nyinshi nk'ibikoresho by'ibanze kandi ikavangwa na coke (anthracite), kandi ishongeshwa mu itanura ry'amashanyarazi rishyushye cyane ku bushyuhe buri hejuru ya 2000°C. Korundum y'umukara ivanze ifite imiterere ikomeye kandi ikomeye cyane, kandi ikunze gukoreshwa mu byuma bya ceramic, mu byuma bikozwe neza no mu bikoresho bigezweho birwanya ubushyuhe.

05Corundum yo munsi y'umweru
Corundum y'umweru ikorwa hakoreshejwe uburyo bwo gushonga bwa bauxite yihariye cyangwa iya mbere mu kirere gituza n'ikirere gicukura. Mu gihe cyo gushonga, ongeramo ikintu gituza (karuboni), ikintu gituza (ibyuma bifunze) n'ikintu gituza (icyuma gipima). Kubera ko imiterere yayo ya shimi n'imiterere yayo biri hafi ya corundum y'umweru, yitwa corundum y'umweru. Ubucucike bwayo buri hejuru ya 3.80g / cm3 kandi ubwinshi bwayo bugaragara buri munsi ya 4%. Ni ibikoresho byiza cyane byo gukora ibikoresho bigezweho birwanya kwangirika n'ibikoresho bidashira.

06Chrome corundum
Hashingiwe kuri korundum yera, hongerwaho 22% bya chromium, kandi ikorwa hakoreshejwe ishongesha mu itanura ry'amashanyarazi. Ibara ni umuhengeri n'umutuku. Ubukana buri hejuru gato ya korundum y'umukara, bisa na korundum y'umweru, kandi ubukana bushobora kuba 2200-2300Kg/mm2. Ubukana buri hejuru kurusha iya korundum y'umweru kandi buri hasi gato y'iya korundum y'umukara.

07Zirconium Corundum
Zirconium corundum ni ubwoko bwa korundum y’ubukorano ikorwa binyuze mu gushonga alumina na zirconium oxide ku bushyuhe bwinshi mu itanura ry’amashanyarazi, ikarema, ikonjesha, igasya kandi igapima. Icyiciro cy’ingenzi cya kristale cya zirconium corundum ni α-Al2O3, igice cya kabiri cya kristale ni baddeleyite, kandi hari n’igice gito cy’ikirahure. Imiterere ya kristale n’imiterere ya zirconium corundum ni ibintu by’ingenzi bigira ingaruka ku bwiza bwayo. Zirconium corundum ifite imiterere yo gukomera cyane, gukomera neza, gukomera cyane, imiterere y’ubucucike, imbaraga zikomeye zo gusya, imiterere ihamye ya shimi, no kudahinduka neza kw’ubushyuhe. Ikoreshwa cyane mu nganda zikora ibintu bitera ubushyuhe n’ibidakora. Dukurikije ingano yayo ya zirconium oxide, ishobora kugabanywamo urwego rubiri rw’ibicuruzwa: ZA25 na ZA40.
