Cov yam ntxwv ntawm chrome-magnesia cib thiab magnesia-chrome cib
Chrome magnesia cib thiab magnesia chrome cib, nws lub ntsiab ntxhia muaj pes tsawg leeg yog spinel thiab magnesia. Nws tseem yog ua los ntawm sintered magnesia thiab chromite ua cov ntaub ntawv tseem ceeb, raws li qhov tsim nyog ntawm cov khoom sib xyaw alkaline refractory. Nws cov khoom raw piv tsis tau meej meej, feem ntau cov hlau ore ntxiv tsawg dua 50% yog hu ua magnesia-chromium cib, 50% lossis ntau tshaj 50% yog hu ua chrome-magnesium cib. Nws cov thev naus laus zis ntau lawm, cov yam ntxwv ua haujlwm thiab siv tau zoo ib yam.
Magnesia-chrome firebrick yog tsim los ntawm magnesia (MgO) thiab chromium trioxide (Cr2O3) ua cov khoom tseem ceeb, thiab magnesia-chrome spinel ua cov ntxhia tseem ceeb. Magnesia-chromium refractory cib muaj qhov zoo ntawm siab refractoriness, siab kub lub zog, muaj zog tiv thaiv alkaline slag yaig thiab muaj zog tiv thaiv thermal shock, thiab lwm yam. Nws yog feem ntau siv nyob rau hauv non-ferrous hlau melting rauv.
