Corundum Mullite Castable Description
Corundum mullite refractory castable waa nooc xoog sare leh oo aan qaabayn agabka refractory ee lagu iibiyo Shirkadda RS, kaas oo loo isticmaali karo foornada sibidhka. Corundum mullite castables waxay qaban karaan sifooyin sare sida xoog burburin sare, xasilloonida heerkulka sare, caabbinta shoogga kulaylka, xirashada iyo caabbinta nabaad guurka kiimikaad ee dahaarka kuleyliyaha saldhigga weyn iyo qalabka kale ee heerkulka sare. castable corundum refractory waxaa loo isticmaali karaa foornada birta, foornada sibidhka, foornada dhalada, foornada samaynta birta, foornada tunnel dhoobada iyo wixii la mid ah.
Guryaha Corundum Mullite Castable
- Xoog sare,
- Iska caabin xoog leh oo xidhashada,
- Iska caabbinta nabaad-guurka wanaagsan,
- Deganaanshiyo naxdin kulayl oo heer sare ah,
- Iska caabbinta heerkulka sare.
Habka wax-soo-saarka ee Corundum Mullite Castable
Alaabta ceeriin ee ugu weyn ee corundum mullite castable waa isku-darka aluminium oxide fudud, macdanta mullite dabiiciga ah oo tayo sare leh, iyo sibidhka calcium aluminate oo ah wakiilka isku xidhka. corundum mullite refractory castable waxaa lagu sameeyay iyada oo heerkul sare oo gubanaya foornada warshadaha horumarsan. corundum mullite xoog dabacsanaan iyo xoog cadaadis ayaa kor u kaca marka hore ka dibna hoos u dhaca korodhka heerkulka daaweynta kulaylka. Oo marka waxa ku jira aluminium awood yar yahay 5%, xoogga dabacsanaantu wuxuu gaaraa xagga sare.
Halabuurka Corundum Mullite Castable
Waxyaabaha ku jira Al2O3 waa in ka badan 90%, iyo corundum mullite insulation kabka leh corundum sida wajiga ugu weyn ee crystal waxaa lagu daraa kala firdhiyey habboon, xinjirowga, fiilooyinka ahama, kuwaas oo la isku daray si waafaqsan formula adag. Kabka loo yaqaan 'corundum mullite castable' wuxuu leeyahay astaamo badan, sida xoog heerkul sarreeya, xidhid-iska-caabbinta iyo ka-hortagga xoqidda, kulaylka sarreeya, caabbinta shoogga kulaylka, iska caabbinta daxalka, xidhidh wanaagsan iyo uumi hore.

Codsiga Corundum Mullite Castable
Corundum mullite refractory castable waxay leedahay astaamo balaadhinta isku midka ah, iska caabin shoog kulayl aad u fiican, xasilloonida mugga heerkulka sare, xoogga heerkulka sare, refractorness sare ee culeyska, heerkul hoose oo heerkul sarreeya, xoog burburin sare, heerka isbeddel cabbir toosan oo hooseeya, adagaanta sare, wanaagsan iska caabinta daxalka kiimikaad, xajinta iyo iska caabinta xidhashada. Sababtoo ah jilayaashan oo kale, iyo corundum mullite insulation castable waa waara in la isticmaalo oo si ballaaran loogu dabaqo foornada warshadaha kala duwan, foornada heerkulka sare iyo qaybaha kale ee muhiimka ah ee heerkulka sare, sida:
- Kuleyliyaha, foornada qaraxa, kariyaha kuleylka kulul, foornada kuleylka,
- Weelka tunnel-ka dhoobada ah, foornada sibidhka, dhuxusha gubta,
- Albaabka foornada, furitaanka quudinta, foornooyinka birta, foornooyinka samaynta birta,
- Qolka gubanaya, qiiqa u janjeedha,
- Kuleyliyaha saldhigga korantada ee weyn, weelka dhalada.
