Lebenka Dhadhanka ah ee Fudud

Alaabooyinka

bulukeetiyada Fudud ee Fudud 1.0

Lebenka fudfudud ee fudfudud waxay ka samaysan yihiin alaab tayo sare leh oo nadiif ah, marka loo eego cufis-jiidka gaarka ah ee badeecada, buuxinta isku-darka organic ayaa lagu daraa, faakuum soo saara oo lagu miiray heerkul sare si loo sameeyo badeecooyin mullite khafiif ah. Iyada oo miisaankeeda fudud iyo waxqabadka kuleylka kulaylka ee aadka u fiican, lebennada mullite ee khafiifka ah ayaa si weyn loogu isticmaalaa dahaarka kululaynta dusha sare ama lakabyada dahaarka ee qalabka kulaylka kala duwan, abuurista xaalado lagu hagaajinayo heerka isticmaalka tamarta ee qalabka.

Sharaxaadda bulukeeti-dhal fudud oo fudud

Maaddooyinka aluminium-alumina-sare leh oo leh mullite sida wajiga ugu weyn ee crystal guud ahaan waxay leeyihiin maadada alumina ee 50% -75%. Heerkulka dib-u-celinta ee lebennada khafiifka ah ee mullite waxay gaari karaan wax ka sarreeya 1790 ℃. Heerkulka bilawga jilcinta culeysku waa 1600-1700 ℃. Cadaadiska heerkulka qolka waa iftiin 70-260MPa. Iska caabbinta shoogga kulaylka wanaagsan. Waxaa jira laba nooc: leben dhoobo ah oo sintered iyo leben isku dhafan oo isku dhafan.

Lebenka mullite-ka ah ee la jeexjeexay ayaa laga sameeyay clinker-alumina bauxite clinker oo ah alaabta ceeriin ee ugu weyn, oo leh qadar yar oo dhoobo ah ama bauxite ceeriin ah sida binder, waana la sameeyay oo la miiray. Lebennada isku dhafan ee isku dhafan waxay ka samaysan yihiin alumina bauxite-sare, alumina warshadaha iyo dhoobada refractory, oo leh dhuxul ama qaybo ganaax ah oo kookaha ah oo lagu daray wakiil yareynaya. Samaynta ka dib, waxaa lagu soo saaraa habka fiyuuska dhimista. Kiristaalo mullite la isku daray way ka weyn yihiin kuwa mullite sintered, iyo caabbinta shoogga kulaylka ayaa ka fiican kan alaabta sinteed. Waxqabadkooda heerkulka sare wuxuu inta badan ku xiran yahay waxa ku jira aluminium iyo isku mid ahaanshaha qaybinta wejiga iyo dhalooyinka.

Qalab sare oo aluminium ah oo dib u celin leh oo leh mullite (3Al2O3 · 2SiO2) oo ah wajiga ugu muhiimsan ee crystal. Waxyaabaha ku jira aluminiumka guud waa inta u dhaxaysa 65% iyo 75%. Marka lagu daro mullite, halabuurka macdanta ayaa sidoo kale ku jira qadar yar oo wajiga galaaska ah iyo quartz oo leh aluminium hoose; iyo qadar yar oo corundum ah oo leh maaddo aluminium sare leh. Lebenka fudfudud ee fudfudud waxa si toos ah loogu isticmaali karaa dahaarka weelka kuleylkoodu sarreeyo, waxaana hadda si weyn loogu isticmaalaa weelka shilka, weelka rullalulatada, dhalooyinka iyo dahaarka weelka batroolka.

Halbeegyada jidheed iyo kiimikaad ee leben-ka-fudud ee fudud waa sida soo socota:

Astaamaha lebenka fudud ee fudud:

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.
