Lub zog RefractoryMagnesia Chrome BricksKev muag khoom, Cov neeg siv khoom hauv Indonesia xaj 20 tuj
Topower magnesia chrome refractory bricks tsuas yog siv nyob rau hauv industrial furnace
Magnesia-chrome refractory yog sintered refractory ua los ntawm magnesia thiab chromite. Yuav kom paub txog cov yam ntxwv ntawm cov khoom no thiab siv nws tsim nyog, koj yuav tsum pib nrog magnesia thiab chromite. (1) Cov khoom siv tshuaj ntawm magnesia Lub ntsiab ntxhia hauv magnesia yog periclase MgO, uas kuj yog ib qho ntawm cov ntxhia hauv cov cement clinker. Periclase tuaj yeem ua ke nrog plaub lub ntsiab hauv cov cement clinker, C3S, C2S, C3A, thiab C4AF. Yog li ntawd, periclase muaj zoo heev corrosion kuj rau cement clinker. (2) Lub cev muaj zog ntawm magnesia Periclase yog cov ntxhia hauv isometric nrog hardness ntawm 6, tus txheeb ze ntom ntom ntawm 3.58, melting point txog li 2800 degree, thermal expansion coefficient ntawm 13.5 × {{13} }/K ntawm 0 txog 1000 degree, thiab thermal conductivity ntawm 3.39 txog 4.19W / (m·K) los ntawm 100 txog 1000 degree .
Magnesia bricks thiab magnesia chrome cib yog alkaline refractory cov ntaub ntawv uas muaj xws li chromite thiab magnesia, thiab belongs rau chromium spinel refractory cov ntaub ntawv. Cov ntsiab lus hauv qab no yuav tsum tau xav txog thaum tsim cov cib no:
(1) Kev cuam tshuam ntawm qhov piv ntawm chromium ore thiab magnesia ntawm cov khoom ntawm chromium-magnesia refractory khoom.
(2) Kev cuam tshuam ntawm matrix ntxhia muaj pes tsawg leeg ntawm cov khoom ua haujlwm.
(3) Kev cuam tshuam ntawm huab cua thaj chaw. Chrome-magnesia refractory cov ntaub ntawv yuav tsum raug rho tawm haujlwm hauv qhov chaw tsis muaj zog oxidizing.
2. Ntau lawm ntawm magnesia-chrome cib
Magnesia chrome cib yog ua los ntawm sintered magnesia thiab chromium ore. Cov ntsiab lus MgO nyob rau hauv cov khoom xyaw yog tswj kom yog 60-70%, thiab cov ntsiab lus Cr2O3 yog 8-12%. Cov khoom no muaj kev ruaj ntseg zoo, refractoriness ntau dua 2000 degree, thiab yog ib qho me ntsis alkaline refractory khoom.
Kev sib xyaw: Chromite yog nkig thiab yooj yim rau crush, yog li nws yog tov rau hauv cov xuab zeb tov khoom;
Moulding: Moulding los ntawm hydraulic xovxwm lossis kev sib txhuam cib xovxwm, qhov ceev ntawm lub cev ntsuab yog 4.3g / cm3;
Kev tua hluav taws: tua hluav taws hauv qhov chaw tsis muaj zog oxidizing ntawm 1600 degree hauv qhov cub;
3. Kev tsim cov thermal shock-ruaj khov magnesia-chrome cib
Cov txheej txheem ntawm thermal shock-ruaj khov magnesia-chrome bricks yog tus cwj pwm los ntawm kev ua kom qhov loj me me thiab txo cov hmoov zoo hauv cov chromite hais los txhim kho thermal shock stability ntawm cov khoom.
4. Kev tsim cov thermal shock-ruaj khov chromium-magnesium cib
Thaum qhov piv ntawm chromium ore rau sintered magnesia xuab zeb yog 50% txhua, cov khoom muaj thermal shock stability.
