Refractory castable yog cov khoom siv cov hmoov av thiab cov hmoov uas ua los ntawm cov ntaub ntawv refractory, nrog qee yam ntawm phau ntawv thiab dej ntxiv. Nws muaj cov kua dej siab thiab yog qhov tsim nyog rau cov khoom tsis muaj zog uas tsim los ntawm kev nroo.
Kev faib tawm cov khoom siv refractory
Refractory castables yog feem ntau yog cais los ntawm cov khoom lossis phau ntawv. Tseem muaj cov kev faib tawm raws cov khoom siv hluav taws xob, xws li thermal refractory castables, acid thiab alkali reawractures ntawm refractory castabment los ntawm phau ntawv:
Hydraulic Binder
Cement-sib khi ua ke: aluminate xis mas (xws li Ca -50 {2}}) lossis siab-alumina xis mas siv yog binder. Nws tawv tawv sai thiab muaj lub zog siab. Nws yog tsim nyog rau nruab nrab thiab tsawg zaus ib puag ncig (xws li cov boiler cov kab thiab cov ya).
Tsawg-cement/Ultra-Low-Maas Cas Casabet(LCC / ulcc): Cov ntsiab lus cement (<8%), excellent high-temperature performance, strong resistance to slag erosion, and is used in high-temperature areas such as blast furnaces and ladles.
Tshuaj Lom Neeg Tshuaj
Phosphate Bonded Casable: phosphoric acid los yog siv cov phau ntawv txhuas (saum ntuj 1600 degree), zoo tshaj plaws hauv lub cub hluav taws xob thiab cov cua sov.
Sock ci (dej iav)
Coagulation Binder
Av nplaum-sib khi ua ke castable: nws tau sib khi nrog micropowder (xws li micropowder) los ntawm kev tshaj tawm lub cev, thiab yog siv rau hauv cov cua sov cua sov thiab cua sov.
Sol Binder
Silica sol / alumina sole cov khoom siv ntom ntom ntom, muaj zog tiv taus cov cua sov thiab corrosion, thiab haum rau cov ntaiv hnyav (xws li lads, rubraces, robr rauv taws).
Organic Binder
Resin / asphalt bonded casable: hatens ntawm tsawg kub thiab ua cov carbon khi rau tom qab kub siab carbonation. Nws yog siv nyob rau hauv blast race tapping raws thiab txhuas elecolytic cells (yuav tsum tau cais los ntawm oxidizing huab cua).
Hauv ntej, castables muaj kev ua tau zoo tshaj plaws, corrosion tsis kam thiab kho tshuab, thiab kev txij nkawm ntawm cov cuab yeej hauv ntau qhov kub ib puag ncig.
Peb lub tuam txhab Refractory ntau yam tsim los ntawm peb lub tuam txhab tau muag zoo thoob plaws tebchaws thiab xa tawm mus rau ntau tshaj 20 lub tebchaws. Peb koom tes nrog ntau lub koom haum tshawb fawb thiab ib txwm tau ua ntej ntawm cov khoom siv hluav taws xob hloov tshiab thiab tshawb fawb thiab kev nthuav dav.
