Khoom Description
Silica Refractory Bricks yog cov khoom siv refractory nrog SiO2 cov ntsiab lus siab dua 93 feem pua. Silica Refractory Bricks yog tsim los ntawm silica nrog SiO2 cov ntsiab lus tsis tsawg tshaj li 96 feem pua, ntxiv cov mineralizing tus neeg sawv cev (xws li cov nplai hlau, txiv qaub mis) thiab cov neeg sawv cev (xws li sulfite pulp pov tseg kua), thiab tom qab ntawd ua los ntawm kev sib tov, molding, ziab, tua hluav taws thiab lwm yam txheej txheem. Qhov siab dua SiO2 cov ntsiab lus hauv cov khoom siv silica, qhov siab dua qhov refractoriness ntawm cov khoom. Cov impurities xws li K2O thiab Na2O yog teeb meem thiab yuav txo tau cov refractoriness ntawm refractory khoom.
Fe2O3, CaO, MgO thiab lwm yam impurities ua lub luag haujlwm ntawm flux. Cov ntaub ntawv raw ntawm qib siab silica bricks xav tau kev kho tshwj xeeb kom tshem tawm impurities.

Daim Ntawv Thov Ntawm Silica Bricks
Silica Refractory Cib feem ntau yog siv nyob rau hauv masonry ntawm carbonization chamber, combustion chamber thiab muab faib phab ntsa ntawm coke ncu (kwv yees li 73 feem pua ntawm cov refractories siv nyob rau hauv lub coke cub yog silicon cib), iav kilns thiab kiln ru tsev thiab phab ntsa, kub load- bearing qhov chaw ntawm qhov cub kub kub, charcoal wax burners thiab lwm yam thermal kilns. Txhawm rau kom muaj peev xwm ua tau zoo ntawm cov niaj hnub loj loj coke ncu, nws yog ib qho tsim nyog yuav tsum tau nyias cov charring chamber, combustion chamber thiab partition phab ntsa ntawm coke qhov cub, uas yuav tsum tau siv high density thiab high thermal conductivity ntawm silicon bricks.
Classification ntawm Silica Bricks
Silica Refractory Bricks ntawm ntau hom, raws li kev siv cov silicon cib tau muab faib ua: coke ncu nrog silicon cib, cua kub cua sov nrog silicon cib, hluav taws xob furnaces nrog silicon cib, iav kilns nrog silicon cib, thiab hais txog. Raws li qhov nyuaj ntawm cov cib hom tau muab faib ua: qauv cib, hom cib dav dav, zoo li cib thiab hom cib tshwj xeeb.
Kev Tiv Thaiv Kev Siv Silica Cib
Nyob rau hauv kev siv ntawm silicon bricks yuav tsum xyuam xim rau cov nram qab no ob lub ntsiab lus:
(1) silicon cov khoom ntawm qhov kub thiab txias vim qhov kev hloov pauv ntawm crystalline daim ntawv ntawm cov quartz residual, lub ntim hloov yog loj, yog li lub qhov cub nyob rau hauv 600 degree hauv qab qhov kub thiab txias yog tsis ncaj heev, nyob rau hauv txias rau 600 degree kom txias. maj mam, kom tsis txhob tawg;
(2) kom deb li deb tau, tsis txhob tiv tauj nrog alkaline slag.
Nyob rau hauv cov txheej txheem ntawm silica bricks, nws yog tsim nyog los siv ib tug ntau yam ntawm cov khoom xyaw thiab multilevel cov khoom xyaw rau nruab nrab cov kev puas tsuaj tshwm sim los ntawm lub ntim expansion ntawm cov khoom thaum lub sij hawm firing, los xyuas kom meej ib tug tsim nyog packing ceev ntawm av nkos, thiab ntxiv txhim kho cov khoom. qhov ntom ntawm cov cib.
Txhawm rau ua silicon cib nrog lub zog compressive siab, ntxiv rau cov duab tshwj xeeb thiab tsim cov cib tsawg, yuav tsum tau siv kom deb li deb tau raws li kev siv tshuab molding.
