Tuag Burnt Magnesia

Magnesia xuab zeb yog ib yam tshuaj uas tsim los ntawm high-temperature calcination ntawm magnesium hydroxide tau los ntawm dolomite, brucite, los yog los ntawm cov tshuaj tiv thaiv ntawm seawater nrog txiv qaub mis nyuj. Nws cov khoom tseem ceeb yog magnesium oxide, thiab nws yuav muaj cov impurities xws li calcium oxide, silicon oxide, thiab hlau oxide. Magnesite feem ntau yog siv los tsim cov khoom siv alkaline refractory, xws li magnesium cib thiab magnesia-alumina cib, nrog rau cov hauv ob sab phlu steel rauv hauv qab. Nws kuj tseem tuaj yeem siv los ua cov khoom siv refractory los ua cov khoom ua ntej cov tshuaj magnesia-chrome cib thiab cov ntaub ntawv tsis zoo li magnesia refractory.

Hauj lwm lawm

ZINFON Tuag Burnt Magnesia yog tsim los ntawm magnesite sintered nyob rau hauv high-temperature ntsug kilns. Nws nta MgO cov ntsiab lus siab txij li 90% mus rau 93%, ua cov khoom siv raw rau kev tsim cov qauv magnesia bricks thiab monolithic refractories.

Nws yog dav siv nyob rau hauv ntau yam kub kub kilns rau steel, cement thiab non-ferrous hlau smelting industries.

Peb muab ntau yam specifications nrog npaj npaj thiab ua raws li ib tug kws refractory khoom tsum.

Cov khoom no yog siv nyob rau hauv zus tau tej cov magnesia bricks, magnesia-alumina cib, thiab magnesia-chrome cib, raws li zoo raws li nyob rau hauv rab phom sib tov, castables, qhuav ramming mixes, txheej masses, thiab cub patching cov ntaub ntawv. Nws kuj yog siv los ua ib qho ntxiv hauv cov suab, cov ntaub ntawv pov thawj, cov khoom siv hluav taws kub thiab cov thermal rwb thaiv tsev, thiab vuam fluxes. Nyob rau hauv industrial furnaces, nws yog siv nyob rau hauv steelmaking furnaces, cua sov rauv, teb kilns, hluav taws xob rauv hauv qab, thiab rammed furnace linings rau steelmaking.

Sintering txheej txheem ntawm tuag-hluav taws Magnesia

Magnesite ore siv rau qhov tuag-hlwb magnesia feem ntau muaj ntau dua 45% MgO, nrog rau tag nrho cov ntsiab lus ntawm Al₂O₃ thiab SiO₂ tsawg dua 4%. Magnesite (MgCO₃) pib decompose ntawm 350℃thiab ua tiav nws decomposition ntawm 1000 degree.

Vertical kilns nrog qhov siab ntawm 10-15 meters thiab txoj kab uas hla ntawm 3-4 meters yog siv. Cov ntaub ntawv nyoos yog pub ncaj qha los ntawm sab saum toj ntawm lub kiln, thiab cov tshuab tshuab tau nruab rau hauv nruab nrab-qis ntu muab cua combustion rau hauv qhov cub.

Lub sintering kub ntawm cov tuag-hlwb magnesia yog nyob ib ncig ntawm 1500 degree. High-purity magnesite tig tawm-dawb grey tom qab calcination. Cov xim ntawm lub tiav lawm-hlaws magnesia txawv nyob ntawm seb cov impurities tam sim no:

~High SiO₂ cov ntsiab lus: tawm-dawb daj

~High Fe₂O₃ cov ntsiab lus: tsaus xim av

~High CaO cov ntsiab lus: dub
