Izitini zeMagnesia zinokungaphezu kuka-90% okuqukethwe kwe-magnesium oxide futhi zisebenzisa i-periclase njengesigaba sekristalu esiyinhloko. Izitini zeMagnesite zingahlukaniswa zibe izigaba ezimbili zezitini ezishisiwe zeMagnesia kanye nezitini ze-Chemical Bonded Magnesite Brick. Izitini ze-Magnesite zinokusebenza okuhle kakhulu kwamandla omshini wokushisa okuphezulu nokuqina kwevolumu. Futhi ingasebenza ekushiseni okuphezulu kwe-1750 ℃, izitini zeMagnesite ziyimikhiqizo efanelekile yokufakwa kwesithando somlilo wengilazi.
Izakhiwo zeMagnesia Bricks
- Ama-refractorine aphezulu,
- Ukumelana ne-alkaline slag,
- Ukumelana nokuguguleka kanye ne-anti-oxidation enhle kakhulu,
- I-refractoriness ephezulu ngaphansi komthwalo,
- Amandla aphezulu emishini,
- Ukuzinza kwevolumu ekushiseni okuphezulu.
Magnesia Bricks Manufacturing Process
Izitini ze-Magnesia zingahlukaniswa zibe izinhlobo ezimbili: isitini se-magnesite esishisiwe kanye nesitini se-magnesite esiboshwe ngamakhemikhali. Izitini ezishisiwe ze-magnesite zenziwe ngezinto ezingavuthiwe ze-periclase, ngemuva kokushiswa ngezinga lokushisa eliphakeme elingu-1550 ~ 1600℃ ngokuchotshozwa, ukuxutshwa, ukuncibilika nokubumba. Imikhiqizo yokuhlanzeka okuphezulu inezinga lokushisa elishisayo elingaphezu kuka-1750 ℃. Isitini se-magnesite esingashisi senziwe ngokwengeza i-ejenti yamakhemikhali efanelekile ngokuncibilika, ukubumba nokomisa.
Izigaba zeMagnesia Bricks
Ngenxa yokwakheka kwamakhemikhali ahlukene ezitini ze-magnesia, ezingahlukaniswa zibe izinhlobo ezahlukene, futhi zonke lezi zitini zikhiqizwa ngokufaka i-sintering. Ngokusekelwe ezintweni zokusetshenziswa ezihlukene, izitini ze-magnesia zingahlukaniswa ngezigaba ezilandelayo:
Isitini se-magnesia esijwayelekile: itshe le-sintered magnesite.
Isitini esiqondile se-magnesia: ukuhlanzeka okuphezulu kwe-sintered magnesite.
Isitini se-Forsterite: i-peridotite
Isitini se-Magnesia calcia: i-sintered magnesite equkethe i-calcium ephezulu.
Isitini se-Magnesia silica: itshe eliphakeme le-silicon sintered magnesite.
Isitini se-Magnesia chrome: i-sintered magnesite kanye ne-chrome ore ethile.
Isitini se-Magnesia alumina: itshe le-sintered magnesite kanye ne-Al2O3.

Ukusetshenziswa kweMagnesia Bricks for Furnace
Izitini ze-Magnesite zilungele zonke izinhlobo zezithando zokushisa eziphakeme, njengeziko le-metallurgical. Ngaphezu kwalokho, izitini ze-magnesia zisetshenziswa kabanzi kwezinye izinto ezishisayo, ezifana ne-hyperthermia tonnel kiln, ulwelwesi lwe-rotary simenti yomlilo, ukushisa phansi kwesithando somlilo nodonga, igumbi lokuvuselela ingilazi yesithando somlilo, isithando somlilo kagesi kanye nodonga nokunye.
IMagnesia Bricks Manufacturer e-ChinaM
Umkhiqizi we-RS refractory ungumkhiqizi wezitini we-magnesia ochwepheshe e-China, angakunikeza izitini ze-magnesite ezisezingeni eliphezulu. Uma unesidingo sezitini ze-magnesia, noma unemibuzo ngezitini ze-magnesia mayelana nezinkomba zomzimba namakhemikhali, sicela usithinte mahhala, ukuthengisa kwethu kuzokuthinta ngokushesha ngangokunokwenzeka.
