Izitena zeMagnesia zinomxholo we-magnesium oxide ongaphezulu kwe-90% kwaye zisebenzisa i-periclase njengesigaba esiphambili sekristale. Izitena zeMagnesite zinokwahlulwahlulwa zibe ziindidi ezimbini zezitena zeMagnesia ezitshisiweyo kunye nezitena zeMagnesite ezibotshelelweyo zeChemical. Izitena zeMagnesite zisebenza kakuhle kakhulu, zinamandla aphezulu oomatshini kunye nozinzo lomthamo. Kwaye zinokusebenza kubushushu obuphezulu be-1750℃, izitena zeMagnesite ziimveliso ezifanelekileyo zokusetyenziswa kwesithando seglasi.
Iipropati zeMagnesia Bricks
- Ii-refractorines eziphezulu,
- Ukumelana ne-alkaline slag,
- Ukumelana nokukhukuliseka kunye nokulwa ne-oxidation egqwesileyo,
- Ukunganyangeki okuphezulu phantsi komthwalo,
- Amandla aphezulu oomatshini,
- Uzinzo lomthamo kubushushu obuphezulu.
Inkqubo Yokuvelisa Izitena ZeMagnesia
Izitena zeMagnesia zingahlulwahlulwa zibe ziintlobo ezimbini: izitena zeMagnesite ezitshisiweyo kunye nezitena zeMagnesite ezibotshelelweyo ngamakhemikhali. Izitena zeMagnesite ezitshisiweyo zenziwe ngezinto eziluhlaza zePericlase, emva kokutshiswa ngobushushu obuphezulu obuyi-1550 ~ 1600℃ ngokutyumza, ukuxuba, ukunyibilika kunye nokubumba. Iimveliso ezicocekileyo kakhulu zinobushushu obuphezulu obuyi-1750℃. Izitena zeMagnesite ezingatshiyo zenziwe ngokongeza i-arhente yekhemikhali efanelekileyo ngokunyibilikisa, ukubumba kunye nokomisa.
Ulwahlulo lweeMagnesia Bricks
Ngenxa yokwakheka kweekhemikhali ezahlukeneyo zezitena ze-magnesia, ezinokwahlulwahlulwa zibe ziintlobo ezahlukeneyo, kwaye zonke ezi zitena ziveliswa ngokusila. Ngokusekelwe kwizinto ezahlukeneyo ezikrwada, izitena ze-magnesia zinokuhlulwahlulwa zibe zezi zilandelayo:
Isitena se-magnesia esiqhelekileyo: ilitye le-magnesite elisikiweyo.
Isitena se-magnesia esibophelelwe ngqo: i-magnesite ecocekileyo kakhulu.
Isitena seForsterite: i-peridotite
Isitena se-Magnesia calcia: i-magnesite exutywe ne-sintered equlethe i-calcium eninzi.
Isitena se-silica seMagnesia: ilitye le-magnesite elinongwe nge-silicon ephezulu.
Isitena se-Magnesia chrome: i-sintered magnesite kunye ne-chrome ore ethile.
Isitena se-Magnesia alumina: ilitye le-magnesite elisinkiweyo kunye ne-Al2O3.

Ukusetyenziswa kwezitena zeMagnesia kwiFurnace
Izitena zeMagnesite zilungele zonke iintlobo zezitovu zobushushu obuphezulu, ezifana nezitovu ze-metallurgical. Ukongeza, izitena zeMagnesia zisetyenziswa kakhulu kwezinye izixhobo zobushushu, ezifana nesitovu se-hyperthermia tunnel, umgca wesitovu sesamente esijikelezayo, umzantsi nodonga lwesitovu sokufudumeza, igumbi lokuvuselela lesitovu seglasi, umzantsi nodonga lwesitovu sombane, njl.njl.
Umenzi wezitena zeMagnesia eChinaM
Umenzi we-RS refractory ngumvelisi weetena ze-magnesia ochwephesha eTshayina, unokukubonelela ngezitena ze-magnesite ezikumgangatho ophezulu. Ukuba unesidingo sezitena ze-magnesia, okanye unemibuzo malunga nezitena ze-magnesia malunga neempawu zomzimba nezekhemikhali, nceda unxibelelane nathi simahla, intengiso yethu iya kuqhagamshelana nawe ngokukhawuleza.
