Brik silica pou gwo founo dife an vè refere a pwodwi refractory siliceuz yo itilize pou bati pati tanperati ki wo nan fou an vè (pa an kontak ak likid vè). Fou pisin lan se yon masonry konplèks ak gwo ki fèt ak divès kalite materyèl refractory. Vout li yo sitou itilize brik silica, mi tete, ak ti founo yo te tout itilize brik silica. Oswa -alumina pwodwi olye. Brik silica yo itilize tou nan vout yo rejenerateur ak brik lasi nan kèk au vè.

Brik silica pou au an vè se yon pwodwi silik refractory sitou itilize nan tridimit pou bati pati tanperati ki wo nan fou an vè. Brik silica pou fou an vè ta dwe gen karakteristik sa yo.

① Volim nan se ki estab nan tanperati ki wo, ak kò a gwo founo pa pral chanje akòz fluctuations tanperati. Akòz tanperati a ralantisman segondè ak pousantaj ranpe ki ba nan brik silica, au an vè ka kenbe kò a gwo founo dife san yo pa deformation nan 1600 degre, ak estrikti a se ki estab.

② Pa gen polisyon nan likid vè a. Eleman prensipal la nan brik silica se SiO2, epi si gen yon blòk oswa sifas k ap fonn gout pandan w ap itilize, li pa pral afekte bon jan kalite a nan likid la vè.

③ Rezistan nan atak chimik. Brik la silica nan estrikti anwo a erode pa gaz la ki gen R2O nan pakèt la vè, ak yon kouch metamòfik lis fòme sou sifas la, ki diminye to a ewozyon ak jwe yon wòl pwoteksyon.

④ Dansite esansyèl la piti. Ka pwa a nan kò a gwo founo dife ap redwi.
