Tuam Tshoj Zoo heev hluav taws kub resistant silica cib refractories los ntawm lub Hoobkas muag Hoobkas thiab cov chaw tsim khoom | Rongsheng

Cov cib silica refractory yog cov kua qaub refractory thiab muaj kev tiv thaiv zoo los ntawm kev yaig ntawm cov kua qaub slag. Cov cib slica refractoriness thaum lub sijhawm thauj khoom yog txog li 1640 ~ 1690 ℃, qhov kub pom tseeb thaum pib mos yog 1620 ~ 1670 ℃ thiab qhov ceev tiag tiag yog 2.35g / cm3. Cov cib hluav taws silicon tuaj yeem ua haujlwm tau ntev hauv qhov kub siab thiab khaws cia qhov ntim ruaj khov yam tsis hloov pauv. Cov cib hluav taws silicon muaj ntau dua 94% SiO2. Cov cib silicate muaj lub zog kub siab thiab tsis tshua muaj kev cuam tshuam thermal. Cov cib hluav taws silicon yog ua los ntawm cov pob zeb silica ntuj ua cov khoom siv raw, ntxiv cov mineralizer tsim nyog los txhawb cov quartz hauv lub cev ntsuab hloov mus ua tridymite thiab hlawv qeeb qeeb los ntawm qhov kub ntawm 1350 ~ 1430 ℃ hauv huab cua txo qis. Thaum cua sov txog 1450 ℃, muaj 1.5 ~ 2.2% ntawm tag nrho cov ntim nthuav dav. Qhov kev nthuav dav tom qab no yuav ua rau kev txiav sib koom ua ke kaw thiab xyuas kom meej tias kev tsim kho khaws cia qhov cua tsis nkag thiab lub zog ntawm cov qauv.

Cov Khoom ntawm Silica Fire Brick

• Zoo acid tiv thaiv kev yaig,
• Lub zog kub siab,
• Kev kub hnyiab siab: 1690 ~ 1710 ° C,
• RUL Siab: txog li 1620-1670 ℃,
• Kev ruaj khov ntawm qhov kub siab,
• Kev tiv thaiv thermal zoo.

Cov khoom xyaw ntawm Silica Fire Brick

Silicon hluav taws thaiv yog ib lub cib refractory uas muaj silica ntau dua 93%, 50% -80% ntawm tridymite, 10% -30% ntawm cristobalite, quartz thiab iav theem, li 5% -15%. Cov mineralogical sib xyaw ntawm silicate cib yog feem ntau scale quartz thiab quartz, nrog rau me me ntawm quartz thiab vitreous. Scale quartz, quartzite quartz thiab residual quartz hloov pauv ntau heev hauv ntim vim yog qhov hloov pauv ntawm cov duab siv lead ua ntawm qhov kub qis, yog li qhov thermal stability ntawm silicate refractory cib tsis zoo ntawm qhov kub qis. Hauv cov txheej txheem siv, nyob rau hauv 800 ℃ kom qeeb cua sov thiab txias, yog li kom tsis txhob tawg. Yog li yuav tsum tsis txhob nyob hauv qab 800 ℃ kub dhia ntawm qhov cub.

Cov Txheej Txheem Tsim Khoom Siv Hluav Taws Xob Silica

Cov cib silicate hluav taws yog ua los ntawm quartzite nrog me ntsis cov mineralizing agent. Thaum hlawv ntawm qhov kub siab, cov cib silica refractory yog tsim los ntawm cov nplai quartz, quartzite quartz, iav thiab lwm yam complex theem cov ntaub so ntswg tsim ntawm qhov kub siab, thiab cov ntsiab lus AiO2 ntau dua 93%. Ntawm cov cib silica hlawv zoo dua, cov ntsiab lus ntawm nplai quartz yog qhov siab tshaj plaws, suav txog 50% ~ 80%. cristobalit yog tom ntej, suav txog tsuas yog 10% txog 30%. Cov ntsiab lus ntawm quartz thiab iav theem hloov pauv ntawm 5% thiab 15%

Cov Lus Qhia Txog Rongsheng Refractory Silica Fire Cib

Daim Ntawv Thov ntawm Silica Fire Brick

Cov cib hluav taws xob silica feem ntau yog siv ua cov khoom siv refractory rau phab ntsa tiv thaiv ntawm chav coking thiab lub combustor hauv qhov cub coke, chav regenerative thiab lub hnab slag hauv qhov cub qhib-hearth steelmaking, qhov cub soaking qhov cub thiab qhov cub iav yaj, thiab lwm qhov chaw hnyav thiab sab saum toj hauv qhov cub ceramic firing. Cov cib silicate kuj tseem siv tau rau thaj chaw hnyav hauv qhov kub siab thiab sab saum toj ntawm qhov cub acid qhib hearth.
