Kubera ko igihugu giha agaciro ku kurengera ibidukikije, nk'ubwoko bw'imyanda ikomeye, uburyo bwo gukoresha icyuma cya slag bwabaye ingingo y'ingenzi. Iyi nkuru itanga igisubizo cyuzuye cya tekiniki cyo kongera gukoresha icyuma cya slag. Ikoranabuhanga ryo gutunganya icyuma ryumye rigomba kwemeza ko ibyuma bisubizwa neza ku ruhande rumwe kandi bigakoreshwa neza ku rundi ruhande. Intambwe zikurikira zo gutunganya icyuma cya slag ziragaragazwa: Guhitamo gusya; gutandukanya magnetike n'uruhare rw'igikoresho gishya gifite umuvuduko mwinshi mu ikoreshwa ryuzuye ry'icyuma cya slag; gukoresha ibikoresho bishya bishobora kugabanya cyane ikiguzi cyo gusya icyuma cya slag, bityo bikabyara inyungu nyinshi mu ikoreshwa rya slag y'icyuma. Guteza imbere ikoreshwa ryuzuye ry'icyuma cya slag byatanze amahirwe. Guteza imbere iki gitekerezo cyuzuye mu nganda bisaba imbaraga zihuriweho z'ibigo bikora ibyuma, impuguke mu gutunganya amabuye y'agaciro n'abahanga, ishyirwa mu bikorwa rusange ry'iyi porogaramu, hamwe n'ishami rishinzwe kwamamaza no kwamamaza.
Imikoreshereze y'icyuma gikozwe mu bwubatsi
1) Icuma gikoreshwa mu gukora sima n'ibindi bivangwa na beto. Icuma gikozwemo amabuye y'agaciro nka tricalcium silicate (C3S), dicalcium silicate (C2S) na aluminate y'icyuma ifite ubushobozi bwo gusimbuza amazi, ibyo bikaba bihuye n'imiterere ya sima. Kubwibyo, gishobora gukoreshwa nk'ibikoresho fatizo na sima mu gukora sima idakoresha icyuma, sima nto ya clinker. Sima ya clag y'icyuma ifite imiterere myiza nko kudashira, gukomera cyane, kurwanya ingese no kurwanya ubukonje.
2) Ibuye ry'icyuma risimbura ibuye ryashenywe n'iry'ibumba. Ibuye ry'icyuma rishenywe rifite ibyiza byo gukomera cyane, ubuso bugoye, kudasaza neza no kuramba, ingano nini, kudahindagurika neza, no guhuza neza na asphalt. Ugereranyije n'ibuye risanzwe rishenywe, rirwanya kandi imiterere y'ubushyuhe buke, bityo rishobora gukoreshwa cyane mu gutunganya imihanda. Ibuye ry'icyuma, nk'iry'umuhanda wa gari ya moshi, rifite imiterere yo kudahungabanya imikorere ya gari ya moshi ndetse no kuyobora neza amashanyarazi. Kubera ko iry'icyuma rituma amazi yinjira neza kandi rigatwara amazi, ibice biyirimo bishobora gutuma ikomera bigahinduka ibice binini. Iry'icyuma rikoreshwa mu kubaka imihanda mu bishanga no ku nkengero z'inyanja.
Kugeza ubu, uburyo busanzwe bwo gukoresha icyuma gikoreshwa mu rugo ni ugusya icyuma gikozwe mu buryo bwa -5mm kugira ngo gisimbuze umucanga wo mu ruzi nk'ibikoresho by'ubwubatsi, cyangwa gusya icyuma gikozwe mu buryo bwa ball-slag kikavamo ifu nziza kugira ngo gikoreshwe nk'inyongera ya sima. Shandong Huate Magnetoelectric Technology Co., Ltd. kandi yakoze ubushakashatsi bwimbitse ku ikoreshwa ry'icyuma gikozwe mu buryo bwagutse, ikoresha uruganda rukora icyuma gishyushya cyane mu buryo bugezweho mu gusya icyuma gikozwe mu buryo bwa elegitoroniki, inoza ikoranabuhanga ryo gutunganya icyuma gikozwe mu buryo bwa elegitoroniki, kandi igera ku nyungu nziza mu bukungu. Yakoreshejwe neza mu bucukuzi bwa Pangang no mu kigo runaka cy'icyuma gikozwe mu buryo bwa elegitoroniki i Lianyungang.
Uburyo gakondo bwo gukora icyuma gikozwe mu buryo bwa “slag” ni ubu bukurikira:
1) Ibice binini bisya hakoreshejwe icyuma gisya urwasaya kugeza kuri -50, hanyuma icyuma gisya urwasaya gitandukanywa n'icyuma gisya urwasaya.
2) Shyira ingano y'icyuma kuri +45 mm. Isigaye ya mm 0-45 ikoreshwa mu kubaka imihanda no kuyizuza. Kugira ngo wongere agaciro k'icyuma gikoreshwa, icyuma gishobora kugabanywamo 0-4, 4-8 n'ibindi byiciro bitandukanye. Ikoranabuhanga risaba imari nto n'ikiguzi gito cyo gukora. Ariko, hejuru ya 50% by'icyuma kiri muri icyuma gishyirwa mu ngufu za mm -10, bityo iri koranabuhanga rizatera igihombo kinini cy'icyuma, ariko icyuma gikomeye kiziyongera.
Kubwibyo, gusya neza byakoreshejwe cyane cyane ku byuma bikozwe mu gukora icyuma gifite aloyi nyinshi kirimo Cr, Ni, Mo, nibindi. Ibikorwa bisanzwe birimo gusya no gusya neza mu ntambwe ebyiri (icyuma cy'inkoni/icyuma cy'umupira). Kubera ko icyuma gifite ubushobozi bwo gusya bitaba byoroshye gusya, gutandukanya icyuma n'icyuma bishobora kugerwaho binyuze mu gusya cyangwa gushyira mu byiciro. Ubunini bw'igice cy'amabuye y'agaciro cya slag akenshi buri hejuru ya 95% no munsi ya 0.2mm. Igipimo cyo kugarura icyuma muri ubu buryo kirenga 95%, kandi umusaruro w'icyuma cyakozwe ni 90 kugeza 92%. Ukurikije uburyo bwo gutandukanya icyuma n'icyuma, ubu buryo bushobora kuvugwa ko ari bwo buryo bwiza.
Ingorane nyamukuru y'ubu buryo ni uko icyuma gitandukanye ari urutare rwiza. Kubera ko uburyo busanzwe butose, biragoye gukoresha mu bwubatsi bw'inyubako. Kubwibyo, ibikoresho byinshi by'icyuma bisigaye nyuma yo guhitamo icyuma birajugunywa, kandi ibi akenshi biterwa n'igiciro kinini cyo kumisha bitose n'amategeko agenga isi yose. Gukoresha igiciro cyose cyo hejuru bisaba ubundi buryo bwo gutunganya umwanda utose (kumisha, gukuba, nibindi).
Ubusanzwe hagomba gutorwa hagati y’igipimo cyo kugarura icyuma cyangwa kuboneka kw’ibisigazwa bisigaye. Ubusanzwe, iri hitamo riterwa n’agaciro k’icyuma cyagaruwe.
Inzira zisanzwe muri iki cyiciro ni izi zikurikira:
Ibice binini bisya hakoreshejwe imashini isya urwasaya kugeza kuri -50, naho icyuma gisya urwasaya kigatandukanywa n'icyuma gisya urwasaya.
Icuma cya -50 gisya gikoreshwa mu gusya inyundo cyangwa gusya inyundo, icusya impact, gicagaguwe mu ruziga rufite ibyiciro byinshi, igicuruzwa cy'umucanga cya -20-10 gishobora gukoreshwa nk'amabuye, igicuruzwa cy'umucanga cya -10-1 gishobora gukoreshwa nk'umucanga muto.
Imbonerahamwe ya 1
Isesengura ry'ingano y'uduce twa mm 50 mu cyuma gisya inyundo
-10 icyuma gisya ingano gishyirwa mu ruganda rwumutse rushyirwamo ifu nziza ya mesh -200, hanyuma hagakoreshwa agakoresho gatandukanya icyuma cyumutse gikoreshwa mu gukuraho icyuma nk'inyongera ya sima.
