Spinel minerals muaj ib qho tseem ceeb ntawm cov khoom kub-kub ntawm cov ntaub ntawv refractory. Piv txwv li, vim yog qhov me me thermal expansion coefficient ntawm spinel (α = 8.9x10-* / ℃ ntawm 100 ~ 900 ℃), spinel yog siv los ua tus neeg sawv cev (los yog hu ua cementing theem, matrix), magnesia-alumina cib nrog periclase. Raws li lub ntsiab siv lead ua theem, thaum kub hloov pauv, qhov kev ntxhov siab sab hauv tsim me me, thiab cov cib tsis yooj yim tawg, yog li thermal stability ntawm bricks tuaj yeem txhim kho (magnesia-alumina bricks The thermal stability yog 50 ~ 150. lub sijhawm).
Tsis tas li ntawd, vim spinel muaj cov khoom zoo xws li siab hardness, ruaj khov khoom, thiab siab melting point, thiab yog heev resistant rau corrosion los ntawm ntau yam melts ntawm kub kub, lub xub ntiag ntawm spinel minerals nyob rau hauv cov khoom tau txhim kho qhov kub thiab txias kev ua tau zoo. khoom.
Lub ntsiab yog vim li cas vim li cas lub high-temperature load softening kub ntawm magnesia-alumina bricks (pib taw tes yog tsis tsawg tshaj li 1550-1580 ℃) yog siab tshaj ntawm magnesia bricks (pib taw tes yog qis dua 1550 ℃) yog hais tias lub matrix muaj pes tsawg leeg yog txawv. .
Piv txwv li, spinels yog cov ntaub ntawv zoo heev nyob rau hauv cov nqe lus ntawm melting point, thermal expansion, hardness, thiab lwm yam, nrog rau cov tshuaj muaj zog ruaj khov, muaj zog tiv thaiv alkaline slag yaig, thiab tsis kam rau molten hlau yaig .Kev sib piv ntawm cov khoom ntawm spinel thiab lwm yam oxides. .
Cov ntaub ntawv yooj yim
Junsheng high-purity magnesium-aluminium spinel system siv high-purity alumina thiab high-purity magnesium oxide ua raw khoom, thiab sintered ntawm kub. Raws li cov tshuaj sib txawv, nws muab faib ua peb qib: SMA-66, SMA-78 thiab SMA-90. Khoom Series.
Junsheng high-purity magnesia-aluminium spinel muaj cov ntsiab lus tsis tshua muaj impurity thiab kev ua haujlwm kub kub zoo heev. High-purity spinel yog tsim rau prefabricated qhov chaw xws li breathable cib, lub rooj cib, ladles, hluav taws xob rauv sab saum toj npog, refractory ntaub ntawv rau teb kilns, thiab refractory ntaub ntawv rau smelting alloys. cov khoom, nrog rau cov spinel-muaj shaping poob lawm.
Cov khoom tuaj yeem pab txhim kho cov slag corrosion kuj ntawm cov ntaub ntawv refractory, thiab daws qhov teeb meem ntawm cov khoom tawg los ntawm kev ntxiv magnesium raw khoom.
