Zvidhinha zveMagnesia zvine huwandu hwemagnesium oxide inodarika 90% uye zvinoshandisa periclase sechikamu chikuru chekristalline. Zvidhinha zveMagnesite zvinogona kukamurwa muzvikamu zviviri zveBurnt Magnesia Bricks neChemical Bonded Magnesite Brick. Zvidhinha zveMagnesite zvine mashandiro akanaka esimba remagetsi pakupisa kwepamusoro uye kugadzikana kwevhoriyamu. Uye zvinogona kushanda pakupisa kwakanyanya kwe1750℃, zvidhinha zveMagnesite zvigadzirwa zvakanaka zvekushandisa muchoto chegirazi.
Zvivakwa zveMagnesia Bricks
- Zvine refractorines dzakawanda,
- Kudzivirira alkaline slag,
- Kuramba kukurwa kwevhu uye kudzivirira kuoxidation kwakanaka,
- Kusagadzikana kwakanyanya pasi pemutoro,
- Simba guru remakanika,
- Kugadzikana kwevhoriyamu pakupisa kwakanyanya.
Maitiro Ekugadzira Zvidhinha zveMagnesia
Zvidhinha zveMagnesia zvinogona kuiswa mumhando mbiri: zvidhinha zveMagnesite zvakatsva uye zvidhinha zveMagnesite zvakasungwa nemakemikari. Zvidhinha zveMagnesite zvakatsva zvinogadzirwa nezvinhu zvisina kugadzirwa zvePericlase, mushure mekupiswa nekupisa kwepamusoro kwe1550 ~ 1600℃ kuburikidza nekupwanya, kusanganisa, kunyungudutsa uye kuumba. Zvigadzirwa zvine hutsanana hwakanyanya zvine kupisa kwakatsva kwe1750℃. Zvidhinha zveMagnesite zvisina kutsva zvinogadzirwa nekuwedzera makemikari akakodzera kuburikidza nekunyungudutsa, kuumba uye kuomesa.
Kupatsanurwa kweMagnesia Bricks
Nekuda kwemakemikari akasiyana-siyana ezvidhinha zvemagnesia, izvo zvinogona kuiswa mumhando dzakasiyana, uye zvidhinha izvi zvese zvinogadzirwa nekugadzira sintering. Zvichibva pazvinhu zvakasiyana-siyana, zvidhinha zvemagnesia zvinogona kuiswa muzvikamu zvinotevera:
Chidhinha cheMagnesia chakajairika: dombo reMagnesite rakacheneswa.
Chidhinha cheMagnesia chakabatana zvakananga: magnesite yakacheneswa zvakanyanya.
Zvidhinha zveForsterite: peridotite
Magnesia calcia brick: magnesite yakasanganiswa ine calcium yakawanda.
Magnesia silica brick: dombo remagnesite rakacheneswa nesilicon yakawanda.
Magnesia chrome brick: sintered magnesite uye mamwe chrome ore.
Magnesia alumina brick: sintered magnesite stone uye Al2O3.

Kushandiswa kweMagnesia Bricks paViniro
Zvidhinha zveMagnesite zvakakodzera marudzi ese ezvitofu zvinopisa zvakanyanya, zvakaita sezvitofu zvesimbi. Pamusoro pezvo, zvidhinha zveMagnesia zvinoshandiswa zvakanyanya mune zvimwe zvishandiso zvinopisa, zvakaita sekiln ye hyperthermia tunnel, lining yekiln yerotary cement, pasi nepamadziro echitofu chinodziya, kamuri regenerative yegirazi, pasi nepamadziro echitofu chemagetsi nezvimwewo.
Mugadziri weMagnesia Bricks muChinaM
Mugadziri weRS refractory inyanzvi yekugadzira zvidhinha zvemagnesia muChina, inogona kukupa zvidhinha zvemagnesite zvemhando yepamusoro. Kana uchida zvidhinha zvemagnesia, kana kuti une mibvunzo nezvezvidhinha zvemagnesia nezvezviratidzo zvemuviri uye zvemakemikari, ndapota taura nesu mahara, vatengesi vedu vachakubata nekukurumidza sezvinobvira.
