Waa maxay qiimaha lebenka refractory ee foornooyinka biraha?

Waa maxay qiimaha lebenka refractory ee foornooyinka biraha? Tani waxay noqon kartaa su’aal ay u baahan yihiin inay ogaadaan saaxiibada ku jira warshadaha birta. Lebennada dib-u-celinta sida caadiga ah loo isticmaalo foornooyinka birta waxaa ka mid ah lebennada silica, lebenka corundum mullite, iyo lebenka birta-magnesia-birta. Waxaa jira noocyo badan oo leben refractory foornooyinka birta ah, iyo qiimaha gaarka ah waa in lagala xaajoodo soo saaraha si ay u doortaan leben refractory ugu haboon. Kuwa soo socdaa waxay soo bandhigayaan lebennada foornada birta ah ee sida caadiga ah loo isticmaalo.

1. Wajiga macdanta ee leben silica ayaa inta badan ka kooban tridymite iyo cristobalite, oo leh qadar yar oo quartz iyo vitreous ah. Heerkulka hooseeya, mugga tridymite, cristobalite iyo quartz haraaga ah ayaa si weyn isbeddelaya sababtoo ah isbeddelka qaabka crystal. Sidaa darteed, xasiloonida kulaylka ee lebennada silica ee heerkulka hooseeya waa mid liita. Inta lagu jiro isticmaalka, waa in si tartiib ah loo kululeeyaa oo lagu qaboojiyaa wax ka hooseeya 800 ° C si looga fogaado dildilaaca. Sidaa darteed, kuma habboona in lagu isticmaalo foornada leh heerkulka degdega ah ee ka hooseeya 800 ° C.

2. Corundum mullite leben waa alumina-aluminium ah oo sarreeya oo ka samaysan corundum iyo mullite. Lebenka Corundum mullite waxay tixraacaan alaabada dib-u-soo-celinta ee laga sameeyay saafi-sare ama alaab cayriin oo saafi ah. Waxay leedahay awood heerkul sare oo wanaagsan, waxqabadka gurguurta heerkulka sare, iska caabinta shoogga kulaylka iyo iska caabinta daxalka. Labada foornada qarxinta shooladaha qaraxa kulul iyo shooladaha dhoobada ah ayaa ku habboon.

3. Lebenka birta birta ah ee birta ah ayaa laga sameeyaa lafdhabarta synthetic oo tayo sare leh sida alaabta ceeriin waxaana lagu farsameeyaa hab gaar ah. Alaabtu waxay leedahay sifooyin xoog cadaadis sare leh, xasilloonida shoogga kulaylka wanaagsan, waxqabadka kulaylka wanaagsan ee gurguurta, iyo heerkulka jilciya culeyska sarreeya. Isla mar ahaantaana, waxay sidoo kale leedahay isku dhafka tooska ah ee lebenka magnesia-chrome oo ay fududahay in lagu dhejiyo maqaarka foornada, taas oo xalliya dhibaatada wasakheynta deegaanka ee chromium hexavalent oo la soo saaro habka isticmaalka lebenka magnesia-chrome ee foornada sibidhka.
