Xaiv qhov tsim nyogCov cib magnesia carbonrau cov cub tawg kev lag luam thiab cov cub tawg kub siab ncaj qha txiav txim siab lub neej ua haujlwm ntawm lub qhov cub tawg, kev ruaj khov ua haujlwm, thiab kev siv nyiaj ntau ntxiv. Ntau tus neeg ua haujlwm hauv Hoobkas feem ntau ntsib teeb meem xws li cov cib tawg, kev tawg slag loj heev, thiab kev puas tsuaj ua ntej rau cov khoom siv refractory. Qhov laj thawj tseem ceeb yog tias lawv tsis ua ke cov xwm txheej ua haujlwm tiag tiag ntawm lub cub tawg thaum xaiv cov cib magnesia carbon thiab tsis quav ntsej cov yam ntxwv tseem ceeb ntawm lub cub tawg.
Ua ntej, phim qib cib raws li qhov kub ua haujlwm tas mus li ntawm lub qhov cub. Rau cov cub tawg hlau hnyav thiab cov cub tawg rotary uas ua haujlwm ruaj khov saum 1700 ° C ntev, nws yog qhov tsim nyog los xaiv cov cib fused magnesia carbon uas muaj cov ntsiab lus MgO ntau dua 97% thiab cov mis tshuaj tiv thaiv oxidant zoo tshaj plaws. Cov cib no tuaj yeem muab lub zog kub ruaj khov thiab zam kev mos thiab deformation nyob rau hauv lub sijhawm ntev kub siab heev. Rau cov cub tawg nruab nrab thiab qis kub nrog kev kaw tsis tu ncua thiab kev hloov pauv kub, cov cib magnesia carbon nruab nrab nrog kev tiv thaiv thermal poob siab txaus, uas tuaj yeem txo cov nqi yuav khoom tsis tsim nyog.
Qhov thib ob, tsom mus rau qhov muaj zog ntawm kev yaig ntawm slag thiab huab cua ib puag ncig hauv lub cub tawg. Rau cov khoom siv hauv lub cub tawg uas sib cuag nrog cov alkaline molten slag muaj zog (xws li cov kab ladle slag thiab cov ntaub thaiv thaj tsam yaj), cov cib magnesia carbon uas muaj qhov ceev thiab qhov porosity qis yuav tsum tau xaiv los thaiv kev nkag mus ntawm slag thiab tiv taus kev yaig ntawm cov tshuaj lom neeg. Rau thaj chaw cub tawg uas muaj cov pa oxygen ntau thiab yooj yim rau kev oxidation ntawm carbon, cov cib magnesia carbon uas ntxiv nrog cov tshuaj tiv thaiv oxidants zoo yuav tsum tau xaiv los qeeb cov pa roj carbon poob thiab tswj kev ruaj khov ntawm cov ntaub thaiv refractory mus sij hawm ntev.
Qhov thib peb, xav txog kev ntxhov siab ntawm lub tshuab thiab cov voj voog kub ntawm cov khoom tseem ceeb ntawm lub qhov cub. Rau cov cheeb tsam cuam tshuam, cov saum toj ntawm lub qhov cub, thiab cov khoom uas muaj kev hloov pauv txias-kub ntau zaus, cov cib magnesia carbon uas tsim nyog nrog cov pa roj carbon tsim nyog yuav tsum tau xaiv los txhim kho kev tiv thaiv kev co thermal thiab kev ua haujlwm tiv thaiv kev stripping, zoo tiv thaiv kev tawg thiab kev poob ntawm lub qhov cub sab hauv thaum lub sijhawm ua haujlwm txhua hnub ntawm lub qhov cub.
Kev xaiv cov cib magnesia carbon uas ntseeg tau tsis yog hais txog kev nrhiav cov khoom siv siab uas tsis pom kev, tab sis hais txog kev sib phim raws li qhov kub thiab txias tiag tiag, cov yam ntxwv ntawm slag, lub voj voog ua haujlwm thiab lub nra hnyav ntawm koj lub qhov cub. Peb cov kev daws teeb meem magnesia carbon tag nrho yog tsim rau ntau hom qhov cub kev lag luam, muab kev sim cov txheej txheem ua haujlwm dawb thiab kev taw qhia kev xaiv ib tus rau ib tus, pab cov chaw tsim khoom txuas lub neej ua haujlwm ntawm cov ntaub hauv qhov cub los ntawm 30% thiab txo qhov poob ntawm cov khoom siv refractory. Yog tias koj xav tau txais daim ntawv qhia xaiv tshwj xeeb thiab cov lus hais raug, thov koj xav nug. Peb yuav teb tam sim ntawd los muab cov khoom siv magnesia carbon uas pheej yig rau koj thiab kev txhawb nqa kev tshaj lij, thiab ua haujlwm ua ke los txo koj cov nqi tsim khoom thiab kev ua haujlwm.
