Silica refractory bricksyog cov khoom siv acid refractory, nrog kev ua haujlwm zoo rau acid slag yaig muaj peev xwm, load softening kub txog 1640 ~ 1670 degree, ntev -lub sij hawm siv ntim yog qhov ruaj khov ntawm qhov kub thiab txias.
Silica cov ntsiab lus siab dua 94%. Qhov ceev tiag tiag 2.35g / cm3. Nws yog resistant rau acid slag. Siab kub lub zog. Qhov pib softening kub nyob rau hauv load yog 1620 ~ 1670 degree. Ntev- siv sijhawm ntev ntawm qhov kub thiab txias yam tsis muaj deformation. Tsis tshua muaj thermal shock stability (kub pauv hauv dej yog 1-4 zaug) ntuj silica li raw khoom, ntxiv rau qhov tsim nyog tus neeg sawv cev mineralizing, txhawm rau txhawb kev hloov pauv ntawm quartz hauv billet rau squame-quartz. Nws maj mam raug rho tawm haujlwm ntawm 1350 ~ 1430℃hauv kev txo cov cua. Thaum rhuab mus rau 1450 degree, tag nrho ntim nthuav dav yog li 1.5 ~ 2.2%. Qhov kev nthuav dav seem no yuav ua rau cov pob qij txha raug kaw thiab ua kom cov huab cua zoo nruj thiab lub zog ntawm lub cev masonry.
Cov ntxhia facies muaj pes tsawg leeg ntawm silica refractory cib yog feem ntau squamous quartz thiab quartzite, nrog me me ntawm quartz thiab vitreous. Lub thermal stability ntawm silicon cib ntawm qhov kub thiab txias yog qhov tsis zoo vim tias qhov ntim ntawm squamous quartz, quartzite thiab residual quartz hloov pauv ntawm qhov kub thiab txias. Nyob rau hauv tus txheej txheem ntawm kev siv, nyob rau hauv 800℃kom maj mam cua sov thiab txias, thiaj li tsis mus tawg. Yog li ntawd, nws yuav tsum tsis txhob siv rau hauv qhov cub nrog kub hloov hauv qab 800 degree.
Cov khoom siv raw rau kev ua silicon refractory cib yog silica. Qhov siab dua cov ntsiab lus ntawm SiO2 hauv silica raw cov ntaub ntawv, qhov siab dua qhov refractoriness. Qhov phem tshaj impurities yog Al2O3, K2O, Na2O, thiab lwm yam., uas txo cov refractoriness ntawm refractory khoom. Silica cib nrog SiO2 cov ntsiab lus tsis tsawg tshaj li 96% silica raws li raw khoom, ntxiv mineralizing tus neeg sawv cev (xws li hlau nplai, txiv qaub mis nyuj) thiab sib txuas tus neeg sawv cev (xws li molasses, sulfite pulp pov tseg kua), tom qab sib tov, sib sau, ziab, hlawv thiab lwm yam txheej txheem.
Silica refractory bricks Feem ntau yog siv rau coke cub carbonization chamber thiab combustion chamber muab faib phab ntsa, steelmaking qhib hearth regenerator chamber thiab sediment chamber, soaking rauv, iav rauv refractory cov ntaub ntawv thiab ceramic firing kiln thiab lwm yam kiln vault thiab lwm yam bearings. Nws kuj yog siv rau qhov kub thiab txias bearing ib feem ntawm kub moj tej tawg qhov cub thiab sab saum toj ntawm acid qhib hearth rauv.
