Xov xwm

covMagnesia-chrome cibyog cov khoom siv refractory yooj yim nrog magnesium oxide (MgO) thiab chromium trioxide (Cr2O3) ua cov khoom tseem ceeb. Nws muaj cov khoom zoo heev xws li siab refractoriness, thermal shock kuj, slag kuj thiab yaig kuj. Nws cov ntxhia tseem ceeb yog periclase thiab spinel. Cov yam ntxwv no ua rau magnesia-chrome bricks ua tau zoo nyob rau hauv qhov kub thiab txias ib puag ncig thiab haum rau ntau yam khoom siv kub kub. cov

Cov khoom xyaw thiab kev tsim khoomcov

Cov ntaub ntawv tseem ceeb ntawm magnesia-chrome cib yog sintered magnesia thiab chromite. Magnesia muaj qhov xav tau purity siab, thaum cov tshuaj muaj pes tsawg leeg ntawm chromite feem ntau yog Cr2O3 cov ntsiab lus ntawm 30% thiab 45%, thiab CaO cov ntsiab lus tsis pub tshaj 1.0% mus rau 1.5%. Cov txheej txheem tsim khoom suav nrog txoj kev sib txuas ncaj qha thiab txoj kev tsis tua hluav taws. Direct bonding magnesia-chrome bricks siv high-purity raw cov ntaub ntawv thiab raug rho tawm haujlwm ntawm qhov kub thiab txias los ua ib theem kub-kub ncaj qha kev sib txuas ntawm periclase thiab spinel, uas ua rau kom muaj zog kub thiab slag kuj. cov

Cov yam ntxwv ua haujlwm
covHigh refractory:Lub refractoriness feem ntau yog siab tshaj 2000 ° C, thiab nws muaj peev xwm ua kom muaj kev ruaj ntseg zoo ntawm qhov kub thiab txias.
Thermal shock resistance:Vim qhov qis thermal expansion coefficient, nws tuaj yeem hloov mus rau qhov kev hloov pauv kub.
Slag resistance:Nws muaj zog tiv thaiv alkaline slag thiab qee cov kua qaub slag, thiab tshwj xeeb tshaj yog haum rau cov cheeb tsam uas raug kub-kub slag.
Corrosion kuj:Nws muaj zog kam rau acid-base alternating yaig thiab roj yaig.
covChemical stability:Cov khoom siv tshuaj tsim los ntawm magnesium oxide thiab chromium oxide nyob rau hauv magnesia-chrome cib muaj tshuaj lom neeg ruaj khov.

Daim ntawv thov teb
Magnesium-chrome bricks yog dav siv nyob rau hauv kev lag luam metallurgical, cement kev lag luam thiab iav kev lag luam:

Kev lag luam metallurgical:siv rau hauv ob sab phlu ntawm high-temperature khoom xws li converters, hluav taws xob arc rauv, qhib hearth furnaces, ladles thiab moj tej tawg furnaces nyob rau hauv lub steel kev lag luam, tshwj xeeb tshaj yog haum rau ib puag ncig ntawm tuav high-temperature alkaline slag.

covKev lag luam cement:siv rau thaj chaw tua hluav taws thiab hloov chaw ntawm cov cement rotary kilns los tiv thaiv kev yaig ntawm qhov kub thiab txias thiab alkaline cua.

Kev lag luam iav:siv rau regenerators thiab cov qauv sab sauv hauv cov iav melting rauv, thiab tuaj yeem tiv taus qhov yaig ntawm qhov kub thiab txias thiab alkaline iav kua.
