Faahfaahin

Qalab sare oo aluminium refractory ah ayaa si weyn loogu isticmaalaa dhismaha iyo dayactirka foornada warshadaha. Kabaha aluminium-sare ee caadiga ah waxaa ka mid ah sibidhka portland, kasalka aluminate sibidhka, kabka biyaha galaas, fosfat bonded castable iyo wixii la mid ah. Hal-abuurnimada joogtada ah ee noocyada badeecadaha, tayada kabka aluminium-ku-sare ayaa sidoo kale si tartiib tartiib ah u soo hagaagtay, oo ay ku jiraan kabka cement-ka hooseeya, kabka sibidhka aadka u hooseeya iyo kabka sibidhka-free.

Shaqada Alaabta

Foornada Ferrosilicon waa foorno koronto oo warshadeed oo cunta awood aad u badan waana nooc ka mid ah foornada fallaadho ee quusta. Foornada Ferrosilicon waxaa ka mid ah qolof foornada, daboolka foornada, dahaarka foornada, shabagga gaaban, nidaamka qaboojinta biyaha, nidaamka qiiqa qiiqa, nidaamka ka saarista boodhka, qolofka korantada, cadaadiska korantada siideynta iyo nidaamka qaadista, nidaamka dejinta iyo dejinta, kontaroolaha, aaladda gubashada, haydarooliga nidaamka, Transformer iyo qalab koronto oo kala duwan, iwm, isticmaalka qalabka refractory sidoo kale waa arrin aad u baahan.

In 2006, Our warshad la aasaasay Yuzhou, saldhigga alaabta ceeriin.High bauxite ore waa isku dar ah kolloidal si yaryar u qaybsan oo ka kooban hydroxides aluminium iyo saamiyo kala duwan. Bauxite-alumina-sare ee warshadaha refractory caadi ahaan waxa loola jeedaa macdanta bauxite oo leh kakoob Al₂O₃ ka kooban 48% iyo ka kooban Fe₂O₃ hoose.

Codsiga Alaabta

Kabka sare ee alumina refractory wuxuu ku habboon yahay foornada kululaynta, foornada qooya, foornada daaweynta kulaylka iyo foornada wareega; Dabool heerkul sare oo kala duwan, foornada kulaylinta dahaarka lagu duubo tuubooyinka biyaha, qaybo ka mid ah qalabka sifaynta ee ka baxsan foornada birta dhalaalaysa iyo dahaarka heerkul-sare ee xidhashada u adkaysta ee reactors katalytic kicinta batroolka; Mashiinnada dahaarka sida tuubada foornada qaraxa, taphole cupola, qoriga budada ah ee isku dhafan ee loogu talagalay daaweynta birta kulul, iwm. Waxa kale oo loo isticmaali karaa in lagu sameeyo baloogyo waaweyn oo horay loo sii diyaariyey iyo dahaarka foornada si degdeg ah loo dhiso.
