Sharaxaadda Corundum Mullite Castable
Corundum mullite refractory castable waa nooc ka mid ah agab aan qaab lahayn oo xoog badan oo lagu iibiyo Shirkadda RS, kaas oo loo isticmaali karo foornada sibidhka. Corundum mullite castables waxay samayn karaan sifooyin sare sida xoog burburin sare, xasillooni heerkul sare, iska caabbinta shoogga kulaylka, xirashada iyo iska caabbinta nabaad-guurka kiimikada ee dahaarka kuleyliyaha saldhigga korontada ee weyn iyo qalabka kale ee heerkulka sare. Corundum mullite castable ee adkeysiga leh waxaa loo isticmaali karaa foornada birta, foornada sibidhka, foornada galaaska, foornada samaynta birta, foornada tunnelka dhoobada iyo wixii la mid ah.
Astaamaha Corundum Mullite Castable
- Awood sare,
- Iska caabin adag oo xirasho,
- Iska caabin wanaagsan oo nabaad-guurka ah,
- Xasillooni shoog kuleyl oo aad u fiican,
- Iska caabin heerkul sare leh.
Habka Wax Soo Saarka ee Corundum Mullite Castable
Alaabada ceeriin ee ugu muhiimsan ee corundum mullite castable waa isku-darka aluminium oxide oo khafiif ah, macdanta mullite dabiiciga ah oo tayo sare leh, iyo sibidhka calcium aluminate oo ah wakiilka isku xidhka. Corundum mullite refractory castable waxaa lagu sameeyaa iyada oo loo marayo gubasho heerkul sare ah foornada warshadaha ee horumarsan. Xoogga dabacsanaanta corundum mullite iyo xoogga cadaadiska ayaa marka hore kordha ka dibna hoos u dhaca marka la kordhiyo heerkulka daaweynta kulaylka. Marka heerka awoodda yar ee alumina uu yahay 5%, xoogga dabacsanaanta ayaa gaara meesha ugu sarreysa.
Halabuurka Corundum Mullite Castable
Waxyaabaha ku jira Al2O3 waa in ka badan 90%, dahaarka corundum mullite-ka ee la tuujin karo corundum oo ah wejiga ugu weyn ee kiristaalka waxaa lagu qasaa kala firdhiyeyaal ku habboon, isku-xidheyaal, fiilooyin bir ah oo aan miridh lahayn, kuwaas oo lagu daray qaacido adag. Corundum mullite oo aan miridh lahayn wuxuu leeyahay astaamo badan, sida xoogga heerkulka sare, iska caabbinta xirashada iyo ka hortagga xoqidda, gudbinta kulaylka sare, iska caabbinta shoogga kulaylka, iska caabbinta daxalka, shaabad wanaagsan iyo qoynta hore.

Codsiga Corundum Mullite Castable
Corundum mullite refractory castable wuxuu leeyahay astaamo ballaarin isku mid ah, iska caabin shoog kuleyl oo aad u fiican, xasillooni mugga heerkulka sare, xoog heerkul sare, iska caabin sare oo culays saaran, heer hoose oo heerkul sare ah, xoog burburin sare, heer hoose oo isbeddel cabbir toosan ah, adkaansho sare, iska caabin wanaagsan oo u adkaysta miridhka kiimikada, iska caabinta xoqidda iyo xirashada. Sababtoo ah sifooyinkaas oo kale, dahaarka mullite ee corundum castable waa mid waara marka la isticmaalo waxaana si ballaaran loogu isticmaalaa foornada warshadaha kala duwan, foornada heerkulka sare iyo qaybaha kale ee muhiimka ah ee heerkulka sare, sida:
- Kuleyliyaha, foornada qaraxa, shooladda qaraxa kulul, foornada kulul,
- Foorno dhoobo ah, foorno sibidh ah, dhuxul gubasho,
- Albaabka foornada, furitaanka quudinta, foornada birta ah, foornada birta ah,
- Qolka gubashada, qiiqa u janjeera,
- Kuleyliyaha saldhigga korontada oo weyn, foornada galaaska.
