siliceous firebrick yog siliceous refractory khoom uas muaj ntau tshaj 90% SiO2 cov ntsiab lus thiab ib tug ntim ceev tsawg tshaj li 1.2g / cm³. Cov ntxhia muaj pes tsawg leeg ntawm silicon hluav taws cib yog: phosphorus quartz 78% ~ 86%, quartzite 13% ~ 15%, quartz 4% ~ 7%. Siliceous tshav kub rwb thaiv tsev firebrick feem ntau siv crystalline quartzite los yog silica xuab zeb ua raw khoom, thiab cov khoom flammable yog ntxiv rau cov khoom xyaw, xws li coke, anthracite, sawdust, carbonized mov husk los yog ntxeem tau qauv yog tsim los ntawm roj foaming txoj kev. Lub refractoriness thiab softening kub nyob rau hauv load tsis ntau txawv los ntawm cov zoo tib yam lub teeb silicon bricks nrog tib yam muaj pes tsawg leeg. Tab sis vim muaj ntau qhov pores, yog li lub zog compressive, slag kuj, corrosion kuj tsis zoo li lub teeb zoo tib yam. silicon cib, thiab thermal shock kuj tau raug txhim kho.
Generallub teeb silicon cibyog muab faib ua: thawj thiab thib ob: thawj lub teeb silicon cib siv tau rau dov steel cua sov rauv sab saum toj thiab silicate muaj rauv sab saum toj thiab lwm qhov chaw, tuaj yeem ncaj qha rau cov nplaim taws; Secondary lightweight silicon bricks yog siv rau rwb thaiv tsev nyob rau hauv dav industrial kilns.
Lub teeb silicon cib yog siv rau hauv: coke cub, kub moj tej tawg rauv, iav rauv, carbon rauv, thiab lwm yam.
Nws muaj kev tiv thaiv hluav taws zoo heev, qhov ntsuas kub ntawm qhov muag yog ze rau lub teeb pom kev zoo silicon cib 1620 degree, muaj qhov seem me me nthuav dav, thiab nws cov thermal stability zoo dua li cov compact silicon cib. Yog li ntawd, lub teeb ci silicon cib tuaj yeem siv tau ntev yam tsis muaj kev sib cuag nrog slag nyob rau hauv qhov kub thiab txias (1500-1550 degree), haum rau lub qhov cub tawg loj uas txhawb nqa kub moj tej tawg rauv hauv ob sab phlu, iav kiln roj rwb thaiv tsev txheej, thiab lwm yam.
