Ingcaciso emfutshane

I-Fused spinel bubunyulu obuphezulu be-magnesia-alumina spinel grain, eveliswa ngokudibanisa i-magnesia yococeko oluphezulu kunye ne-alumina kwi-exlectric arc furnace. Emva kokuqina kunye nokupholisa, iyatyunyuzwa kwaye ihlelwe ngokwemilinganiselo yeed. Ngenye yezona zinto zixhaphakileyo ezixhathisayo.Ukuba nobushushu obuphantsi be-thermal yokusebenza, zibalaseleyo kwi-high refractoriness ukuzinza kwe-thermal kunye nokuzinza kweekhemikhali, i-magnesia-alumina spinel yinto ecetyiswayo kakhulu ye-refractory ekrwada. Iimpawu zayo ezibalaseleyo ze-tic ezinjengombala omnandi kunye nenkangeleko, ukuxinana okuphezulu kwesambuku, ukuchasana okunamandla ekukhupheni kunye nokuchasana okuzinzileyo kumothuko we-thermal, okuvumela ukuba imveliso isetyenziswe ngokubanzi kwiziko elijikelezayo, uphahla lweziko zombane zentsimbi kunye nokunyibilikiswa kwentsimbi, isamente. i-rotary kiln, i-glass furnace kunye ne-me etallurgical industry etc.


Inkqubo yeMveliso kunye nesicelo

Yenziwe ukusuka kwimagnesia yococeko oluphezulu kunye neBayer inkqubo ye-alumina kwiziko elikhulu lombane le-arc. Ineempawu ezigqwesileyo eziphikisayo, kwaye ingasetyenziselwa ukuvelisa izitena kunye neeCastables kwiindawo apho ukumelana ne-slag kungundoqo.

Okunje: Uphahla lwe-EAF kunye nesithando somlilo esisisiseko se-oksijini, i-ladle yensimbi, indawo ephakathi ye-sement rotary kiln, njl.

Iimpawu zeFused Spinel

Intshayelelo yemveliso:I-Fused magnesia-aluminium spinel yenziwe nge-alumina ekumgangatho ophezulu ephantsi-sodium i-high-purity light-burned magnesia powder njengempahla ekrwada, kwaye inyibilikiswa kwiziko lombane le-arc ubushushu obuphezulu obungaphezulu kwe-2000℃.

Iimpawu zeMveliso:ukumelana nobushushu obuphezulu, ukuxinana komzimba okukhulu, ukufunxwa kwamanzi aphantsi, i-coefficient encinci yokwandisa i-thermal, uzinzo olulungileyo lokothuka kwe-thermal, ukuxhathisa okuqinileyo kwe-corrosion kunye nokumelana ne-slag.

Xa kuthelekiswa nendlela ye-sintering yokudibanisa i-spinel, indlela ye-electrofusion inokushisa okuphezulu kwe-calcination, malunga ne-2000 ° C, eyenza i-spinel denser, inomthamo ophezulu we-volume, kwaye ixhaphake ngakumbi kwi-hydration. Inkqubo iyafana nendlela ye-sintering yokwenza i-spinel.

Iimathiriyeli ekrwada ikakhulu zisebenzisa i-alumina yeshishini kunye nekhwalithi ephezulu etshiswe yi-magnesium oxide powder.

Ukusetyenziswa kwemveliso:Isetyenziswa kakhulu ekunyibilikiseni intsimbi, uphahla lweziko lombane, ileli, isitofu esijikelezayo sesamente, isithando somlilo seglasi kunye neshishini lesinyithi, njl.

iibhodi zokutyibilika, izitena zombhobho, izitena zokhuko lwelayile kunye nezitena ezimcaba eziko, kwakunye nesamente yobungakanani obukhulu Izixhobo ezisisiseko zokutshiza, izitena zokhuko lwezowuni yeembalo zesamente ezinobungakanani obuphakathi, izinto ezirhangqwayo eziqholiweyo kunye nezitena zefanitshala yefenitshala yobushushu obuphakamileyo nobuphakathi.

Inkqubo yeMveliso yeFused Spinel

Imveliso yenkampani ye-aluminium edibeneyo ye-magnesium spinel inamanqanaba amaninzi, ngokweemfuno zabasebenzisi, ubungakanani bamasuntswana, ukulunga kunokuveliswa ngokufunwa.
