Cadaadis Heer Sare ah, Cufnaanta Jirka Weyn, Nuugista Biyaha Hoose, Kordhinta Kulaylka Yar ee Laf-dhabarta Fused

Magnesium aluminium spinel
Magnesium aluminate spinel oo isku qasan
Nadiifin sare oo isku dhafan laf dhabarta

Sharaxaad Gaaban

Spinel Fused waa hadhuudh magnesia-alumina ah oo nadiif ah oo nadiif ah, taas oo ay keentay in lagu daro magnesia daahirnimo sare leh iyo alumina foornada qallafsan. Adkeynta iyo qaboojinta ka dib, waa la jajabiyaa oo lagu qiimeeyaa cabbirrada ed. Waa mid ka mid ah xeryahooda refractory ee ugu adkaysiga badan Sifooyinkeeda aadka u fiican sida midabka wanaagsan iyo muuqaalka, cufnaanta sare ee cufan, iska caabin xoog leh oo u adkaysta iyo iska caabin xasilloon oo shoogga kulaylka ah, taas oo u oggolaanaysa badeecada in si weyn loogu isticmaalo kilns rotary, saqafka foornooyinka korantada ee birta iyo dhalaalka birta, sibidhka foornada rotary, foornada dhalada iyo me etallurgical warshadaha iwm.

HADDA LA XIRIIR

Habka Waxsoosaarka iyo Codsiga

Waxaa laga soo saaray magnesia daahirnimo sare leh iyo habka Bayer alumina ee foornada weyn ee koronto. Waxay leedahay sifooyin dib-u-celin heersare ah, waxaana loo isticmaali karaa in lagu soo saaro bulukeeti iyo Castables meelaha ay iska caabbinta dharbaaxadu fure u tahay.

Sida: Saqafka EAF iyo foornada oksijiinta aasaasiga ah, birta birta ah, aagga dhexe ee foornada rotary cement, iwm.

Astaamaha Laf-dhabarta isku-dhafka ah

Soo bandhigida alaabta:Magnesia-aluminium spinel fused waxay ka samaysan tahay aluminium-sodium-yar oo tayo sare leh, budo magnesia ah oo nadiif ah oo nadiif ah oo gubanaysa sida alaabta ceeriin, waxaana lagu dhalaalay foorno koronto oo heerkul sare ah oo ka sarreeya 2000 ℃.

Tilmaamaha alaabta:iska caabin heerkul sare ah, cufnaanta jirka oo weyn, nuugista biyaha hoose, isugeynta fidinta kulaylka yar, xasilloonida shoogga kulaylka wanaagsan, iska caabinta daxalka xooggan iyo iska caabinta slag.

Marka la barbar dhigo habka sintering si synthesize spinel, habka korantada ayaa leh heerkulka calcination sare, oo ku saabsan 2000 ° C, taas oo ka dhigaysa cufnaanta laf dhabarta, uu leeyahay cufnaanta mugga sare, oo aad u adkaysta fuuqbaxa. Nidaamku wuxuu la mid yahay habka sintering si loo soo saaro lafdhabarta.

Alaabta ceeriin waxay inta badan isticmaalaan aluminium-warshadaha iyo budada magnesium oxide oo tayo sare leh oo iftiin leh.

Isticmaalka alaabta:Waxaa si weyn loo isticmaalaa in dhalaalidda birta, saqafka foornada korontada, saqafka, foornada cement rotary, foornada warshadaha galaaska iyo warshadaha biraha, etc.It waa wax ku habboon soo saaridda shuban joogto ah.

lebennada iskateetka, lebenka birta ah, lebennada dahaarka leh ee lebenka iyo lebenka foornada fidsan, iyo sidoo kale sibidhka baaxadda weyn Alaabada ceeriin ee aasaasiga ah ee foornada, lebenka dahaarka aagga kala-guurka ee foornada sibidhka dhexdhexaad ah, castables refractory iyo heerkul sare iyo mid dhexdhexaad ah leben alaabta guriga.

Habka Alaabta Laf-dhabarta Isku Filan

Wax soo saarka shirkadda ee aluminium magnesium spinel oo isku dhafan ayaa leh heerar badan, marka loo eego shuruudaha isticmaalayaasha, cabbirka qaybta, ganaaxa ayaa la soo saari karaa baahida.
