Clay lebenkii alwaax ahaanta ku shaqeeya foornada qaraxa

Lebenka dhoobada refractory ee foornada qaraxas waa in laga sameeyaa dhoobo refractory oo loogu talagalay dahaarka gidaarada foornada qaraxa. Lebenka celiska dhoobada ee foornooyinka qaraxa waxaa loo isticmaalaa cunaha, shafka, foornada, gunta dahaarka foornada qaraxa yar iyo shafka foornada foornada weyn ee qaraxa.

Lebenka celinaya dhoobada ee foornada qaraxu waxay u baahan yihiin xoog cadaadis sare leh oo ah walxaha dab-demiska ee heerkulka qolka, kaas oo iska caabin kara waxyeelada shaqada ee muddada dheer ee alaabta qashinka dib loo rogay; hoos u dhigista mugga yar ee hoos yimaada shaqada muddada-dheer ee heerkulka sare ayaa faa’iido u leh ilaalinta dhamaystirka daboolka foornada; borosity hoose oo muuqda iyo Fe:O. Mawduuca biyaha hooseeya wuxuu yarayn karaa isku-ururinta dhirta kaarboon ee daloolka hawo-mareenka wuxuuna ka hortagayaa lebenka refractory bararka iyo dabacsanaanta iyo burburinta inta lagu jiro habka codsiga oo dhan; Maaddooyinka dhibicda dhalaalka hooseeya ayaa la soo saaraa wax ka yar. Lebenka dhoobada ah ee foornooyinka qarxinta ayaa leh sifooyin ka wanaagsan lebenka dhoobada caadiga ah.
