Hauv kev lag luam coking,silica cibs yog cov khoom siv refractory tseem ceeb rau kev tsim cov khoom tseem ceeb xws li coking chamber thiab combustion chamber ntawm coke ncu. Ntawm lawv, siab - zoo silica cib (hom GZ-94) rau coke cub yog cov khoom siv sawv cev tshaj plaws.
Cov khoom no yog tsim los ntawm quartzite raws li raw khoom, nrog SiO ₂ cov ntsiab lus ntawm ntau dua los yog sib npaug rau 94%, siab refractoriness ntawm 1690-}1710 degree, thiab ib tug load softening kub tsis tsawg tshaj li 1620 degree; Qhov pom meej porosity tswj tau qis dua 22%, nrog rau qhov zoo tshaj plaws-kub ntim ruaj khov thiab qis qis qis; Nyob rau tib lub sijhawm, nws muaj zog tiv thaiv cov kua qaub slag yaig, zoo thermal shock stability, thiab tuaj yeem tiv taus qhov kub thiab txias hloov pauv los ntawm kev thawb lub sijhawm thiab cov thee thauj khoom ntawm coke ncu rau lub sijhawm ntev.
Silicon bricks siv nyob rau hauv coke ncu yog tsuas yog ua rau ntawm phab ntsa ntawm carbonization chamber, combustion chamber, inclined channel cheeb tsam, thiab lub cub tawg sab saum toj. Lawv cov thermal conductivity zoo heev pab txhim kho cov thermal efficiency ntawm coking, thaum lub zog muaj zog txaus ua kom lub sij hawm ntev -kev ruaj ntseg ntawm lub cub tawg lub cev nyob rau hauv qhov kub thiab txias thiab mechanical stress. Cov khoom no yog cov khoom siv tseem ceeb rau kev ua haujlwm nyab xeeb ntawm thawj tiam coke cub (txog 25 xyoos).
