Dab tsi ntawm refractory cib siv rau lub tshuab hluav taws xob lub cev thiab lub cub tawg hauv qab?
01. Txheej txheem cej luam ntawm refractory cib rau blast furnaces
Lub qhov cub tawg tau muab faib ua peb ntu: sab sauv, nruab nrab thiab qis. Lub sab sauv thiab nruab nrab ntawm lub qhov cub me me muaj qhov kub thiab txias yam tsis muaj slag yaig. Phosphorus impregnatedav nplaum ciblos yogsiab alumina cibfeem ntau yog siv. Cov tshuab hluav taws xob loj feem ntau siv high-aluminium cib nrog sillimanite lossis andalusite composites.
02. Lub qhov cub tawg lub cev muaj cov av nplaum ntom ntom
Lub qhov cub tawg lub cev kuj yog ua los ntawm cov av nplaum nplaum refractory cib. Raws li lub cub tawg kub thiab hnyav hnyav ntawm qhov cub loj thiab nruab nrab tau hloov kho dua tshiab, phosphorus-impregnated av nplaum cib kuj tau siv nyob rau sab sauv ntawm lub qhov cub, thiab cov khoom siv qis qis-alumina cib kuj siv rau sab sauv thiab nruab nrab qhov chaw. Qhov cub me me kuj tseem tuaj yeem siv high-alumina cib nrog cov ntsiab lus txhuas ntau dua 75%.
03.Qhov qis ntawm lub qhov cub lub cev yog qhov yooj yim rau kev puas tsuaj
Qhov yooj yim tshaj plaws ntawm lub tshuab hluav taws xob lub cev yog qhov qis ntawm lub tshuab hluav taws xob lub cev, vim tias thaj chaw no yog thaj chaw uas muaj kev sib hloov cua sov ntau dua, thiab qhov qis dua ntawm lub qhov cub lub cev yuav raug kev sib txhuam thiab cov plua plav yaig vim cov nqi poob. Kuj tseem muaj kev xeb loj heev los ntawm cov hlau alkali. Siv cov av nplaum ci, siab alumina cib, corundum cib los yog silicon carbide cib. Nyob rau hauv ib co txawv teb chaws steel nroj tsuag, siab alumina cib, av nplaum-bonded silicon carbide cib, silicon carbide graphite cib, thiab lwm yam, raws li zoo raws li fused siab alumina cib los yog hluavtaws mullite cib. Hauv Suav teb, corundum cib los yog silicon carbide composite cib feem ntau yog siv.
04. Ceramic bonded silicon carbide cib yog siv nyob rau hauv qis qis ntawm lub qhov cub lub cev
Qhov qis ntawm lub qhov cub tawg lub cev yog ua los ntawm ceramic-bonded silicon carbide refractory cib. Raws li kev siv, silicon carbide cib zoo dua li phosphorus-impregnated av nplaum cib, tab sis tus nqi kuj siab. Txawm hais tias tus nqi ntawm phosphorus-impregnated av nplaum yog qhov tsawg, cov txheej txheem ntawm phosphorus-impregnated av nplaum yog teeb meem. Muaj ntau manufacturers tsis kam tsim cov khoom no. Hloov chaw, lawv feem ntau siv cov av nplaum uas tsis tshua muaj ntxeem tau nrog tib qhov tshwj xeeb xws li phosphorus-impregnated av nplaum cib. Tam sim no, cov hauv qab ntawm qhov cub tawg yog ua los ntawm txhuas-carbon cib thiab microporous cib. Aluminium carbon cib, semi-graphite carbon cib, nws tus kheej ci carbon cib thiab cov ntaub ntawv carbon ramming. Raws li kev siv, silicon carbide cib tau dav siv nyob rau hauv qis qis ntawm lub tshuab hluav taws xob tawg. Vim tias silicon carbide cib raug kev txom nyem tsawg dua, thiab qhov qis dua ntawm lub tshuab hluav taws xob lub cev yog cov kab nrog silicon carbide cib, nws yuav pab txhim kho thermal efficiency thiab ntev kev pab cuam lub neej.
Silicon carbide cib kuj tseem siv nyob rau hauv qis qis ntawm lub qhov cub tawg lub cev. Qhov laj thawj tseem ceeb yog tias silicon carbide refractory bricks tsis hnov mob nrog lub qhov cub tawg slag, thiab silicon carbide cib muaj thermal shock stability thiab hnav tsis kam thaum tiv thaiv qhov tshwm sim ntawm tawv nqaij. Silicon carbide cib tuaj yeem hais tias yog ib qho zoo tshaj plaws hauv ob sab phlu refractory cib rau hauv qab ntawm qhov cub tawg.
