Kukaniza Kutentha Kwambiri, Kuchulukana Kwa Thupi Lalikulu, Kutsekemera kwa Madzi Otsika, Kuwonjeza Kwamatenthedwe Ang'onoang'ono Kofanana ndi Fused Spinel

  • Magnesium aluminate spinel
  • Kuphatikiza kwa magnesium aluminate spinel
  • Kuyera kwakukulu kosakanikirana ndi spinel

Kufotokozera Kwachidule

Fused spinel ndi njere yoyera ya magnesia-alumina spinel, yomwe imapangidwa ndi kusakaniza magnesia apamwamba kwambiri ndi alumina mu ng'anjo yamagetsi yamagetsi.Pambuyo kulimbitsa ndi kuziziritsa, imaphwanyidwa ndikusinthidwa kuti ikwaniritse makulidwe a ed.Ndi imodzi mwazinthu zotsutsana kwambiri ndi refractory compounds.Kukhala ndi kutentha kochepa kotentha kogwira ntchito, kumakhala kochititsa chidwi kwambiri pa kutentha kwapamwamba komanso kukhazikika kwa mankhwala, magnesia-alumina spinel ndizomwe zimalimbikitsidwa kwambiri zowonongeka.Makhalidwe ake abwino kwambiri monga mtundu wabwino ndi maonekedwe, kachulukidwe wochuluka, kukana kwambiri kuphulika komanso kukana kugwedezeka kwa kutentha, zomwe zimapangitsa kuti mankhwalawa agwiritsidwe ntchito kwambiri muzitsulo zozungulira, denga la ng'anjo zamagetsi ndi chitsulo chosungunula, simenti. ng'anjo yozungulira, ng'anjo yamagalasi ndi ine etallurgical mafakitale etc.


Njira Yopanga Ndi Kugwiritsa Ntchito

Wopangidwa kuchokera ku high purity magnesia ndi Bayer process alumina mu ng'anjo yayikulu yamagetsi yamagetsi.Ili ndi zinthu zabwino kwambiri zokanira, ndipo imatha kugwiritsidwa ntchito kupanga Njerwa ndi Castables m'malo omwe kukana kwa slag ndikofunikira.

Monga: Denga la EAF ndi ng'anjo yoyambira ya okosijeni, chitsulo chachitsulo, malo apakati a simenti yozungulira ng'anjo, etc.

Makhalidwe a Fused Spinel

Chiyambi cha malonda:Fused magnesia-aluminium spinel amapangidwa ndi aluminiyamu yotsika kwambiri ya sodiamu ufa wonyezimira kwambiri woyaka ngati zida zopangira, ndipo amasungunuka mu ng'anjo yamagetsi yamagetsi yotentha kwambiri kuposa 2000 ℃.

Zogulitsa:kukana kutentha kwambiri, kachulukidwe kakang'ono ka thupi, kuyamwa kwamadzi otsika, kagawo kakang'ono kakuwonjezera kutentha, kukhazikika kwamphamvu kwamafuta, kukana kwa dzimbiri komanso kukana kwa slag.

Poyerekeza ndi njira yopangira sintering kuti apange spinel, njira ya electrofusion imakhala ndi kutentha kwapamwamba kwa calcination, pafupifupi 2000 ° C, yomwe imapangitsa kuti spinel denser, ikhale ndi mphamvu zambiri, ndipo imagonjetsedwa ndi hydration.Njirayi ndi yofanana ndi njira ya sintering yopangira spinel.

Zopangira zake makamaka zimagwiritsa ntchito aluminiyamu yamafakitale ndi ufa wapamwamba kwambiri woyaka ndi magnesium oxide ufa.

Kugwiritsa ntchito mankhwala:Amagwiritsidwa ntchito kwambiri pakusungunula zitsulo, denga la ng'anjo yamagetsi, ladle, ng'anjo yozungulira simenti, ng'anjo yamagalasi yamafakitale ndi mafakitale azitsulo, etc.Ndizinthu zabwino zopangira kuponyera mosalekeza

ma skateboards, njerwa zapamphuno, njerwa zomangira ladle ndi njerwa zoyatsa moto, komanso simenti yayikulu yopangira zida zoyatsira, njerwa zomangira za simenti zazikuluzikulu zapakatikati, njerwa zomangira ndi njerwa zapanyumba zotentha kwambiri komanso zapakatikati.

Fused Spinel Product process

Kupanga kwa kampani ya aluminiyamu yosakanikirana ndi magnesium spinel ili ndi magawo ambiri, malinga ndi zomwe ogwiritsa ntchito amafuna, kukula kwa tinthu, fineness akhoza kupangidwa pakufunika.
