Pob zeb Magnesia-chromeyog ib yam khoom siv refractory yooj yim uas muaj magnesium oxide (MgO) thiab chromium trioxide (Cr2O3) ua cov khoom tseem ceeb. Nws muaj cov yam ntxwv zoo heev xws li kev ua kom refractoriness siab, tiv taus thermal shock, tiv taus slag thiab tiv taus kev yaig. Nws cov khoom siv tseem ceeb yog periclase thiab spinel. Cov yam ntxwv no ua rau magnesia-chrome cib ua haujlwm tau zoo hauv qhov chaw kub siab thiab tsim nyog rau ntau yam khoom siv kub siab.

Cov khoom xyaw thiab cov txheej txheem tsim khoom

Cov khoom siv tseem ceeb ntawm cov cib magnesia-chrome yog sintered magnesia thiab chromite. Magnesia muaj qhov yuav tsum tau purity siab, thaum cov tshuaj lom neeg ntawm chromite feem ntau yog Cr2O3 cov ntsiab lus ntawm 30% thiab 45%, thiab CaO cov ntsiab lus tsis pub tshaj 1.0% txog 1.5%. Cov txheej txheem tsim khoom suav nrog txoj kev sib txuas ncaj qha thiab txoj kev tsis tua hluav taws. Cov cib magnesia-chrome sib txuas ncaj qha siv cov khoom siv raw purity siab thiab raug hlawv ntawm qhov kub siab los tsim cov theem kub siab ncaj qha ntawm periclase thiab spinel, uas txhim kho qhov kub siab thiab kev tiv thaiv slag.

Cov yam ntxwv ntawm kev ua tau zoo
Cov khoom siv refractory siab:Qhov refractoriness feem ntau yog siab dua 2000 ° C, thiab nws tuaj yeem tswj tau qhov ruaj khov zoo ntawm qhov kub siab.
Kev tiv thaiv thermal shock:Vim yog qhov coefficient thermal expansion qis, nws tuaj yeem hloov kho rau qhov kev hloov pauv loj heev ntawm qhov kub thiab txias.
Kev tiv thaiv slag:Nws muaj zog tiv taus alkaline slag thiab qee cov acidic slag, thiab tshwj xeeb tshaj yog rau cov chaw uas raug rau cov slag kub siab.
Kev tiv thaiv corrosion:Nws muaj kev kam rau siab rau kev hloov pauv acid-base thiab kev hloov pauv roj.
Kev ruaj khov tshuaj lom neeg:Cov tshuaj khov uas tsim los ntawm magnesium oxide thiab chromium oxide hauv cov cib magnesia-chrome muaj kev ruaj khov tshuaj lom neeg siab.

Cov teb thov
Cov cib magnesium-chrome siv dav hauv kev lag luam metallurgical, kev lag luam cement thiab kev lag luam iav:

Kev lag luam metallurgy:siv rau hauv cov khoom siv kub siab xws li cov hloov pauv, hluav taws xob arc furnaces, qhib qhov cub furnaces, ladles thiab blast furnaces hauv kev lag luam hlau, tshwj xeeb tshaj yog haum rau ib puag ncig ntawm kev tuav cov alkaline slag kub siab.

Kev lag luam cement:siv rau thaj chaw tua hluav taws thiab thaj chaw hloov pauv ntawm cov cement rotary kilns kom tiv taus qhov kev yaig ntawm qhov kub thiab txias thiab alkaline huab cua.

Kev lag luam iav:siv rau cov khoom siv rov ua dua tshiab thiab cov qauv sab saud hauv cov qhov cub tawg iav, thiab tuaj yeem tiv taus qhov kev yaig ntawm huab cua kub thiab kua iav alkaline.
