Kubara Furnace Silica Amatafari

Ibikoresho byo kuvunika byakoreshwaga kumurongo wa slag ya salle yo hambere byahujwe neza n'amatafari ya magnesia-chrome, gushonga amashanyarazi hanyuma bigahuzwa n'amatafari ya magnesia-chrome hamwe nandi matafari meza ya alkaline. Amatafari ya MgO-C amaze gukoreshwa neza muguhindura, amatafari ya MgO-C nayo yakoreshejwe mumurongo wa slag ya salle yo gutunganya, kandi ibisubizo byiza byagezweho. igihugu cyanjye n'Ubuyapani muri rusange bikoresha amatafari ya MgO-C ahujwe na karuboni ifite 12% kugeza kuri 20%, mu gihe Uburayi bukoresha cyane amatafari ya MgO-C ahujwe na asfalt, hamwe na karuboni hafi 10%.

Imashini ya Kokura ikora ya Sumitomo Metal Corporation mu Buyapani yakoresheje amatafari ya MgO-C ifite MgO ya 83% na C igizwe na 14-17% kugirango isimbuze amatafari ya magnesia-chrome ihujwe mu murongo wa VAD, hamwe nubuzima bwa serivisi bwa slag umurongo wariyongereye uva ku nshuro 20 ugera inshuro 30-32 [9]. Uruganda rwa LF rutunganya uruganda rukora ibyuma bya Sendai mu Buyapani rwakoresheje amatafari ya MgO-C mu gusimbuza amatafari ya magnesia-chrome, kandi ubuzima bwa serivisi bw’umurongo wa slag bwiyongereye kuva ku nshuro 20-25 bugera ku nshuro 40, bugera ku musaruro mwiza. Osaka Ceramics Refractory Co., Ltd. yize ku ngaruka ziterwa na karubone nubwoko bwa antioxydeant ku kurwanya okiside, kurwanya slag hamwe nubushyuhe bwo hejuru bw’amatafari ya MgO-C. Ubushakashatsi bwerekana ko amatafari ya MgO-C akozwe mu ruvange rwa magnesia yahujwe na magnesia yacumuye, hamwe na 15% ya fosifore grafite hamwe na magnesium-aluminiyumu nkeya nka antioxydants, bigira ingaruka nziza zo gukoresha. Iyo ikoreshejwe mumurongo wa toni 100 ya LF ya llag, igipimo cyangiritse kigabanukaho 20-30% ugereranije n'amatafari ya MgO-C afite karubone ya 18% kandi nta antioxydeant, kandi ikigereranyo cy'isuri ni 1,2-1.3 mm / itanura [1].

Kuva igihugu cyanjye cyatunganijwe neza amatafari ya slag umurongo wafashe amatafari ya MgO-C aho kuba amatafari ya magnesia-chrome, ingaruka zikoreshwa zose zaragaragaye. Muri Nyakanga 1989, itsinda rya Baosteel Group Corporation 300t ladle slag ryatangiye gukoresha amatafari ya MT-14A magnesia-karubone muri Nyakanga 1989, kandi ubuzima bwumurongo wa slag bwagumye hejuru yinshuro 100; 150T itanura ryamashanyarazi ya ladle slag ikoresha amatafari make ya karubone magnesia-karubone kugirango ushongeshe ibyuma, hamwe nubushyuhe bwo gukubita bwa 1600 ℃ ~ 1670 ℃, ibyo bikaba byageze kubisubizo bigaragara.

Isosiyete yacu izobereye mu gukora amatafari ya karubone ya magnesia, amatafari ya karuboni ya aluminium-magnesia, amatafari ya karubone y’amatafari atunganijwe, amatafari ya karubone ya aluminium-silicon ya karuboni ya tanpedo, hamwe n’amatafari mashya ya magnesia adafite karubone hamwe n’inganda zitandukanye za amorphous, nko gusana n'ibikoresho byo kurasa kubihindura, itanura ry'amashanyarazi na salle. Dutanga kandi ibicuruzwa byakozwe na vibrasiya, nk'amatafari yo mu kirere yoroheje, amatafari yo mu kirere yinjira mu kirere, amatafari y'intebe ya nozzle n'ibikoresho byateguwe. Twateje imbere uruganda rwuzuye rwo guhuza ibikorwa byubushakashatsi bwibanze, gutunganya byimbitse nubucuruzi. Laboratoire yacu ifite ibikoresho byuzuye byo gupima no kugenzura. Ibikoresho byacu birashobora gukora ibikoresho bibisi, ibicuruzwa byarangiye, kugerageza no kugenzura, no guteza imbere ibicuruzwa bishya. Twizera ko siyanse n'ikoranabuhanga bituyobora. Kubwibyo, twabonye ikoranabuhanga ryateye imbere mugihugu ndetse no hanze yarwo, dukomeza kunoza ubuziranenge bwibicuruzwa, ubumenyi bwa tekinoloji hamwe n’umutekano uhoraho, bityo tunoza ikoranabuhanga ry’umusaruro kandi duhora tuvugurura ibikoresho by’umusaruro. Dutanga serivisi zuzuye za tekiniki dukurikije ingano n'ibipimo bya tekiniki byabahindura, itanura rya arc n'amashanyarazi dukurikije ibyo abakiriya bakeneye.
