Cov cua kub cua sov tau muab faib ua rau hauv lub cub tawg, roj system, cov khoom siv cua, cov pa hluav taws xob, qhov cua txias thiab lub cub tawg yog qhov chaw uas muaj cov phab ntsa ntawm lub cub tawg, lub cub tawg sab saum toj thiab lub cub tawg hauv qab, thiab cov castables sib txawv yog siv nyob rau hauv txhua qhov chaw.
1. Tsawg cement castable yog siv los khi cov qauv ntawm cov kab dej kab ke, thiab cov kab yeeb nkab thiab sab qis ntawm cov nqaj txhawb nqa hauv lub cub tawg yog txhua yam siv nrog cov cement castable tsawg. Tsawg cement castable kuj tseem siv nyob rau hauv thaj chaw uas tsis muaj qhov kub thiab txias ntawm lub qhov cub cua sov, qhov hluav taws xob thiab qhov cub lub cev uas tsis tshaj 1300 degree.
Qhov thib ob, tus kheej-leveling castable yog siv nyob rau hauv cov cua kub cua sov qauv yog complex, phau ntawv yuav tsis vibrate ib feem. Kev siv kub yog 1500 degree, uas yog tus cwj pwm los ntawm kev ua haujlwm zoo thermal shock, siab refractoriness, yooj yim siv, thiab yuav luag tsis muaj kev vibration.
Thib peb, phosphate castable yog tsim rau hauv qab ntawm lub qhov cub cua sov thiab lwm qhov chaw uas hnyav dua los ntawm cov khoom sib txhuam thiab cov cua kub ntxuav, siv kev sib xyaw ntawm 1000-1600 degree, nws yog castable nrog phosphoric acid los yog phosphate li. ib daim ntawv cog lus, aluminium thiab calcium cement thiab magnesia ua coagulant.
4. Mullite castable: Vim nws cov thermal shock tsis kam, yaig tsis kam, zoo ntim stability thiab siab siv kub, mullite castable feem ntau yog siv nyob rau hauv qhov tseem ceeb ntawm cov cua sov rauv phab ntsa, rauv sab saum toj thiab qis beam.
Thib tsib, anti-qhuav slag castable: haum rau hauv qab ntawm lub qhov cub cua sov thiab tso nyiaj ntawm hlau oxide slag. Kev ua haujlwm kub tuaj yeem ncav cuag 1600 degree. Nws cov yam ntxwv tseem ceeb yog: siab refractoriness, zoo thermal poob siab tsis kam, thiab zoo tsis kam mus yaig ntawm hlau oxide slag nyob rau hauv lub qhov cub cua sov.
6, lub teeb castable: haum rau tshav kub rwb thaiv tsev txheej ntawm lub cub tawg phab ntsa, rauv sab saum toj, flue thiab lwm yam. High-strength lightweight castables kuj tseem siv tau los ua cov ntaub ntawv ua haujlwm rau cov pa hluav taws xob thiab cov kav dej kub. Nws yog tus cwj pwm los ntawm qhov ntim me me, zoo thermal stability, tsis tshua muaj thermal conductivity thiab qee yam refractoriness.
Bauxite cement castable yog ib hom castable uas yog ua los ntawm aluminate cement ua tus neeg sawv cev thiab sib xyaw nrog ntau yam refractory aggregates thiab hmoov nyob rau hauv ib qho kev faib ua feem. Nws muaj cov yam ntxwv ntawm kev ceev ceev solidification, siab zog, thermal shock kuj thiab slag kuj. Nws tsis tsuas yog ua tau raws li qhov hluav taws kub tsis kam ntawm lub tshuab hluav taws xob lub cev, tab sis kuj txhim kho kev tsim kho ntawm lub tshuab hluav taws xob lub cev.
