Silica Refractory Cib
Cov cib refractory silicayog cov khoom siv refractory zoo siv dav hauv ntau qhov chaw ua haujlwm kub siab.
1. Cov Ntaub Ntawv Tseem Ceeb
Cov Cheebtsam Tseem Ceeb:Nws yog cov khoom siv acidic refractory nrog silicon dioxide (SiO₂) ua lub ntsiab tivthaiv, feem ntau nrog cov ntsiab lus ntawm ntau dua 93%, thiab cov cib silica zoo tuaj yeem ncav cuag li 96%.
Cov Tshuaj Muaj Peev Xwm Ib Txwm Muaj:Ntxiv rau SiO₂, nws kuj muaj me me ntawm Al₂O₃ (kwv yees li 0.8% - 1%), MgO (kwv yees li 0.001%), CaO (kwv yees li 0.002%), thiab Fe₂O₃ (kwv yees li 0.7% - 1.5%).
Cov Khoom Siv Lub Cev:Qhov refractoriness feem ntau yog nruab nrab ntawm 1770 ° C thiab 2000 ° C. Qhov refractoriness nyob rau hauv ib qho kev thauj khoom ntawm 0.2MPa yog 1630 ° C - 1680 ° C. Lub zog crushing txias yog 30 - 35MPa, qhov ceev ntawm qhov loj yog 1.8g / cm³, thiab qhov pom tseeb porosity yog 21% - 22%.
2. Cov Txheej Txheem Tsim Khoom
Cov txheej txheem tsim khoom suav nrog kev xaiv cov khoom siv raw, kev ua kom zoo nkauj, kev hlawv, thiab kev txias. Cov khoom siv raw tseem ceeb yog quartz, thiab cov khoom siv khi xws li txiv qaub ntsuab thiab cov khoom siv khi organic raug ntxiv. Tom qab tsim rau hauv cov cib dawb, lawv raug hlawv ntawm qhov kub siab ntawm 1350 ° C - 1430 ° C. Cov txheej txheem hlawv xav tau kev tswj qhov kub kom meej, thiab cov txheej txheem txias kuj yuav tsum tau ua qeeb qeeb kom tsis txhob muaj cov kab nrib pleb los ntawm kev hloov pauv sai.
Nta:
1. Muaj zog tiv taus acidic slag erosion:Cov cib silica muaj zog tiv taus cov tshuaj corrosive xws li acidic slag thiab molten hlau, ua kom lawv lub neej ua haujlwm ntev.
2. Kub siab ua kom mos:Qhov kub ntawm cov cib silica ua rau lub nra hnyav nce mus txog 1640-1670 ℃, thiab qhov ntim ruaj khov nyob rau hauv kev siv ntev ntawm qhov kub siab.
3. Kev ruaj khov ntawm lub ntim zoo:Thaum kub txog 1600 ℃, cov cib silica tuaj yeem tswj tau qhov ruaj khov thiab muaj qhov nrawm qis.
4. Kev ruaj khov tshuaj lom neeg siab:Cov cib silica muaj kev tiv thaiv zoo rau cov oxides xws li Al2O3, FeO, Fe2O3, tab sis tsis zoo tiv thaiv alkaline slag (xws li CaO, K2O, Na2O).
