Fused magnesia yog cov khoom siv high-purity, high-melting-point, ntom alkaline refractory cov ntaub ntawv uas muaj qhov ntom ntau dua 3.40 g / cm³, porosity ntawm 0% -10%, Mohs hardness ntawm 5.5, thiab muaj zog tiv taus alkaline slag yaig. Nws yog ib qho tseem ceeb raw khoom rau metallurgy, kev tsim kho, lub teeb kev lag luam, rauv hauv ob sab phlu, thiab tej ntaub ntawv, thiab yog indispensable nyob rau hauv steel, cement, iav, thiab non-ferrous hlau smelting industries. Nws yog dav siv nyob rau hauv metallurgy, iav, cement industries, tsev tso cua sov, thiab high-temperature chemical industries. Nws yog tsim los ntawm melting nyob rau hauv ib tug hluav taws xob arc rauv, nrog cov yam ntxwv ntawm siab purity, loj siv lead ua nplej, ntom qauv, muaj zog slag kuj, thiab zoo thermal shock stability, ua rau nws ib tug zoo heev high-temperature hluav taws xob insulating khoom. Lub ntsiab raw khoom rau hluav taws xob fused magnesia yog xaiv high-qib ntuj periclase los yog high-purity lub teeb-hlwb magnesia, uas yog yaj nyob rau hauv ib tug hluav taws xob arc rauv thiab ces txias. Vim nws cov khoom zoo heev ntawm lub cev thiab tshuaj lom neeg, nws suav hais tias yog cov khoom siv tseem ceeb rau kev tsim cov qib siab magnesia cib, magnesia-carbon cib, thiab cov khoom siv amorphous refractory.
Reburned magnesia yog ib qho tshuaj lom neeg feem ntau tsim los ntawm magnesium oxide, nrog siab heev refractoriness. Nws yog tsim los ntawm purifying ntuj qib high-qib dolomite ore los ntawm flotation, lub teeb hlawv, zoo sib tsoo, high-pressure briquetting, thiab ultra-high-temperature calcination nyob rau hauv ib tug ntsug kiln. Thaum 1800 degree, cov pa roj carbon dioxide hauv cov dolomite ore raug tshem tawm tag, tsim cov periclase tuab.
Medium-grade magnesia yog cov khoom siv hluav taws xob zoo nrog cov ntsiab lus magnesium oxide siab, feem ntau nyob ib ncig ntawm 95%, thiab qhov ntom ntom feem ntau siab dua 3.17 g / cm³. Cov txheej txheem tsim muaj xws li kev kub hnyiab hauv lub qhov cub tawg, kev sib tsoo zoo, dej sib xyaw thiab briquetting, ua raws li kev sib xyaw nrog cov khoom siv roj thiab qhov kawg calcination nyob rau hauv ib qho ntsug kiln. Lub ntsiab siv lead ua theem yog periclase, nrog cov muaju feem ntau sib npaug thiab tsis xwm yeem. Nws cov qib zoo sintering thiab ntom crystallization ua rau nws dav siv los tsim cov khoom nruab nrab qib magnesia refractory, xws li magnesia bricks thiab ladle precast qhov chaw.
High-purity magnesia muaj qhov ntom ntom saum 3.25 g / cm³, MgO cov ntsiab lus ntawm 96.5% thiab 98.5%, tshuaj lom neeg ruaj khov zoo heev, thiab lub zog txhua yam. Nws yog lub teeb daj xim nrog lub melting point saum 2800 degree thiab yog ib qho tseem ceeb raw khoom rau kev tsim high-qib magnesia bricks, magnesia-chrome cib, thiab magnesia-alumina spinel cib.
Fused magnesia-chrome xuab zeb yog ib qho tseem ceeb ntawm cov khoom siv refractory, tus yam ntxwv los ntawm purity siab, siab melting point, thiab ntom qauv. Kuj hu ua magnesia-chrome ore los yog magnesia-chrome spinel, nws yog ib qho yooj yim refractory raw khoom feem ntau tsim ntawm periclase thiab chromite spinel. Nws yog tsim los ntawm artificially synthesizing (los ntawm sintering los yog hluav taws xob fusion) ib tug sib tov ntawm magnesia raws li raw cov ntaub ntawv (xws li sintered magnesia, ntuj magnesite, los yog lub teeb-hlwb magnesia los ntawm seawater / brine-derived magnesium hydroxide) thiab chromite. Ua feded magnesia-chrome xuab zeb muaj lub siab yaj tau muaj siab txog 2800 degree, nrog cov qauv ua tiav thiab ua tiav cov qauv kev ntxhib.
Cov khoom siv no muaj kev ruaj khov, muaj zog compressive, zoo heev rwb thaiv tsev zog, thiab tiv taus yaig thiab corrosion, ua rau nws yog ib qho tseem ceeb raw cov ntaub ntawv nyob rau hauv metallurgy, siv cov ntaub ntawv, lub teeb kev lag luam, furnace linings, thiab tej ntaub ntawv. Tsis tas li ntawd, fused magnesia-chrome xuab zeb muaj kev tiv thaiv zoo heev rau tshuaj tua kab mob los ntawm alkaline slags thiab oxides. Vim nws cov purity siab thiab zoo heev lub cev thiab cov khoom siv tshuaj, nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim ib nrab-rebonded magnesia-chrome cib, fused rebonded magnesia-chrome cib, rauv hauv ob sab phlu, thiab ntau yam kub kub.
