Khethollo ea Fused Spinel le Sintered Spinel

Spinel (MgO · Al2O3, e khutsufalitsoeng e le MA) ke eona feela motsoako oa binary tsamaisong ea binary ea MgO-Al2O3.E ka qhibiliha hanyane ka MgO le Al2O3 ho theha tharollo e tiileng e lekantsoeng.Corundum (α-Al2O3) tharollo e tiileng ea spinel e thehoa ka mokhoa o ruileng oa Al2O3;periclase solid solution spinel e thehoa ka sebopeho se ruileng sa MgO.Ho qhibiliha ho hoholo ho tiileng ho etsahala ho lithempereichara tse peli tse hlahlobiloeng tsa eutectic tsa MA-Al2O3 le MgO-MA, e leng 1925 °C le 1995 °C, ka ho latellana.

 

Ha MgO le Al2A li theha spinel ho latela sebopeho sa theoretical, e tla hlahisa hoo e ka bang 8% ea keketseho ea molumo, ka hona ho thata ho tsitlella ha sintered, 'me ho bonolo ho kopanya le MgO kapa Al: ntlha e bohale ea tharollo e tiileng ea MgO. kapa Al2O3 Spar e na le botsitso bo betere ba mocheso oa mocheso ka lebaka la phapang ea coefficient ea katoloso lipakeng tsa liminerale.

 

Ho ea ka mokhoa oa ho kopanya oa spinel, o ka aroloa ka sintered spinel, fused spinel le spinel e sebetsang, ho phaella ho spinel e phahameng haholo.

1. Sintered spinel le electrofused spinel li hlahisoa ka mekhoa ea sintering le electrofusion, ka ho latellana;

2. Active spinel e boetse e entsoe ka mokhoa oa sintering, empa e fapane le sintered spinel, mocheso oa eona oa motsoako o tlaase (1200-1300 ℃), 'me motsoako ha o fetohe ka ho feletseng hore e be spinel, empa o na le palo e nyenyane ea mahala α -Al2O3 le kapa mahala MgO, e sebelisoa haholo-holo e le matrix a li-spinel refractories kapa tlhahiso ea spinel e phahameng haholo:

3. Bongata bo bongata ba spinel ea high-density spinel ka kakaretso e kholo ho feta 3.40g/cm3, hangata e entsoe ka phofo ea spinel e sebetsang ka ho hatella Ball kapa ho hatelloa, e sintered mocheso o phahameng oa hoo e ka bang 1700 ° C.

4. Fused spinel ke mofuta o phahameng oa bohloeki ba maiketsetso a maiketsetso a refractory, a entsoeng ka alumina le leseli le phahameng le chesitsoeng ka magnesium e le lisebelisoa tse ka sehloohong tse tala 'me li pholile ka mor'a ho qhibiliha ka mocheso o phahameng ka holimo ho 2300 ℃ ka sebōping sa motlakase sa arc.

Fused alumina magnesia spinel e na le letsoalo le phahameng haholo 'me e na le khanyetso e ntle ea kutu, khanyetso ea slag le botsitso ba mocheso oa mocheso.Se latelang ke setšoantšo sa mokokotlo o kopantsoeng oa Yufa Group:
