1, Ubuziranenge nubwiza bwimibanire
Isuku bivuga umubare, imiterere nogukwirakwiza ibintu bitari ibyuma mubyuma.Ugereranije no gupfa,imashini ikomezainzira ihuza, gusuka umwanya ni muremure, kubwibyo kwinjiza ibintu byinshi bituruka, ibihimbano nabyo biraruhije;ibivuye muri kristu ya feri ya feri ya cavit ireremba bigoye cyane, cyane cyane umuvuduko mwinshi wo gushushanya umuvuduko muto wa bilet bigoye kuyikuramo.Kuba haribintu byangiza bikomeza ubucucike n'ubucucike bwa matrix y'ibyuma.Kinini kirenga 50μm kinini kirimo guherekezwa no gucikamo ibice, bikavamo inshuro nke imiterere ya bilet ikomeza guterana yananiwe, gusiba amasahani, no kwangirika hejuru yicyuma gikonje gikonje, nibindi, ibyuma birangiza cyane.Ingano, imiterere nogukwirakwiza ibyongeweho kumiterere yicyuma nabyo biratandukanye, niba ibiyishyizwemo ari bito, serefegitura, gukwirakwiza gukwirakwiza, ingaruka kumiterere yicyuma kuruta kwibumbira hamwe kwa bike;iyo ibyinjijwe ari binini, ni ugukwirakwiza impanuka, nubwo umubare muto ariko nanone ukangiza cyane kubicuruzwa.
Kurugero: uhereye kumashanyarazi yashushanyije cyane icyuma gikubita igenzura ryagaragaye ko ibice biboneka kuri 100 ~ 300μm bidasanzwe CaO-Al2O3 na Al2O3 heterometallic nini cyane.
Kurugero, kuberako hariho Al2O3 yinjizwamo munsi yuruhu rwa bilet ikomeza guterwa, kuzunguruka hejuru yurupapuro rwimodoka rufite inenge z'umukara, bikaviramo gutwikirwa neza kurupapuro.
Hariho kandi no gupakira amasahani yometseho amabati, hiyongereyeho ibisabwa byimikorere ikonje cyane, ingano numubare wabyo nabyo bifite ibisabwa bijyanye.Kububyimbye bwa plaque 0.3mm yoroheje, mumwanya wa 1m2, ubunini bwibice bitarenze 50μm byongeweho bigomba kuba munsi ya 5, kugirango ugere ku gipimo cya 0,05% cyangwa munsi yacyo, ni ukuvuga gukubita cyane amabati 2000 DI, igorofa iri munsi ya 1.Reba rero akamaro ko kugabanya umubare wibisobanuro muriguhorahokuzamura ubwiza bwurupapuro rwimbitse.
Ku nsinga nziza cyane (nka 0.01 ~ 0,25mm ya diameter ya tine yicyuma) hamwe nicyuma cyoroshye cyane (nkubunini bwa 0.025mm isahani yometseho amabati), ubunini bwibirimo burimo nibisabwa cyane.
Mubyongeyeho, ingano numubare wibisobanuro ku bwiza bwibyuma n'ingaruka z'ubuso bwihariye bwa bilet.Igisate rusange hamwe na bilet yuburebure bwubuso (S) nubunini (V) igipimo cya 0.2 ~ 0.8.Hamwe niterambere rya plaque yoroheje hamwe na tekinoroji yoroheje, S / V kugeza 10 ~ 50, niba ibivanze kimwe mubyuma, isahani yoroheje hamwe nicyuma cyoroshye, bivuze ko ibyegeranye byegereye ubuso bwa bileti, niko binini Ingaruka ku musaruro wubwiza bworoshye.Mugabanye rero ibyinjijwe mubyuma nibyingenzi.
2, Kunoza ubuziranenge bwingamba
Kunoza ubuziranenge bwibyuma bigomba kuba mubyuma muri kristalisiti mbere, uhereye kubikorwa kugirango hagabanuke umwanda wibyuma, kandi ugabanye ibyinjira mubyuma ukuyemo.Kugira ngo ibyo bishoboke, hagomba gufatwa ingamba zikurikira.
a, Nta shitingi ivuye mu byuma: uhindura agomba guhagarika icyuma hanze yicyuma, itanura ryamashanyarazi ukoresheje itanura rya eccentric munsi yicyuma, kugirango wirinde icyuma mumashanyarazi cyangwa indobo yicyuma, tank.
b, Ukurikije ibyiciro byicyuma gikenewe kugirango uhitemo uburyo bunoze bwo gutunganya ibyuma bisukuye, kunoza morphologie yibitekerezo.
C. Emera tekinoroji yo gusuka idafite ubusa.Nyuma yo kunonosora imiti, ogisijeni yibyuma byashongeshejwe yagabanutse kugera kuri 20 × 10-6;mucyuma cyuma tank ikigega giciriritse → kristallizer ikoreshwa mukurinda gusuka;ikigega giciriritse ukoresheje ibice bibiri bya shitingi itwikiriye, ibyuma bitandukanijwe numwuka kugirango birinde okiside ya kabiri yicyuma gishongeshejwe.
d.Tanga gukina byuzuye kuruhare rwikigega cyo hagati metallurgical purifier.Gukoresha kuvuza Ar gukurura, kunoza imigendekere yicyuma, gukuraho zone yapfuye ya tank hagati;kongerera ubushobozi ikigega giciriritse no kongera ubujyakuzimu bwa pisine yashonga, kwagura igihe cyo gutura cyuma gishongeshejwe muri tank hagati, guteza imbere kureremba kwinjizwamo, no kurushaho kweza ibyuma bishongeshejwe.
f.
g, Tanga gukina byuzuye kuruhare rwa kristalisiti yashongeshejwe ibyuma bisukura hamwe na billet yubuziranenge bugenzura.Ikibanza cyatoranijwe cyo kwibiza kigomba kugira imiterere ifunguye ninguni, kugenzura urujya n'uruza rw'inshinge, kugirango biteze imbere gutandukanya kureremba kureremba;kandi byuzuzanya nuburyo bwiza bwimikorere yo gukingira, gukurura gushonga kureremba gushonga ibyuma bisukuye.Byongeye kandi, kristalisiti irashobora kandi kugaburirwa mu nsinga zometseho amabara kugirango igere kuri micro-alloying muri kristaliseri, ibyo ntibitezimbere gusa igipimo cyo kwinjiza amavuta, kandi irashobora kugenzura neza ibigize ibyuma bishongeshejwe, bigahindura imiterere ikomeye, kunoza morphologie yibitekerezo, bifasha kunoza no kweza ubwiza bwibyuma.
h.Tekinoroji ya elegitoroniki ikoreshwa mu kugenzura urujya n'uruza rw'inshinge.Ibiharuro byerekana ko muburyo buhagaze, burenze 1mm ibice bya slag bireremba umuvuduko wa 100 ~ 200cm / s;no guterwa inshinge kumanuka umuvuduko wa 60 ~ 10cm / s;ikigaragara cya kristaliseri yamazi ya cavit mumyanya yo guterwa urujya n'uruza rw'ahantu hareremba kureremba biragoye;bimwe mubishobora kuba byugarijwe no gukomera kwa dendrite.
Mubyukuri, mumashusho ya bilet iri munsi ya 10 ~ 20cm akenshi ushyira hejuru.Kwishyiriraho feri ya electromagnetic irashobora kubuza kugenda guterwa inshinge, guteza imbere kureremba no kunoza isuku yicyuma.
