Magnesite chrome block siv zoo magnesia thiab chromic oxide raws li cov khoom siv raw, molded los ntawm kev kub siab thiab raug rho tawm haujlwm hauv qhov kub thiab txias. magnesia chrome cib muaj cov yam ntxwv ntawm cov siv lead ua loj thiab cov nyiaj ncaj qha sib txuas. thiab magnesite chrome hluav taws cib muaj qhov ua kom tawg tau zoo thiab zoo acid slag yaig tsis kam nrog cov khoom qis alkaline. magnesite chrome block yog cov khoom siv zoo tshaj plaws hauv ob sab hauv cib rau kev nplua nuj tawm ntawm lub cub tawg, hluav taws xob rauv, iav rauv, melting rauv thiab teb cement kiln.
Vim qhov zoo ntawm magnesia chrome cib, magnesia chrome cib muab faib ua magnesia chrome cib, ncaj qha sib txuas magnesia chrome cib, semi bonded magnesia chrome cib, rebonded magnesia chrome cib thiab lwm yam.
Magnesia chrome cib yog ua los ntawm cov khoom sib txuas sib txuas, thiab tshem tawm cov nyhuv xoob los ntawm kev nthuav dav thaum tsim cov spinel los ntawm cov tshuaj tiv thaiv ntawm MgO thiab Cr2O3, Al2O3 lossis FeO. Tsis tas li ntawd, tseem muaj qhov tsis muaj hluav taws kub hnyiab magnesite chrome hluav taws cib xws li unburned magnesite chrome block yog ua los ntawm inorganic magnesia saline tov. thiab unburned magnesia chrome cib yog qhov yooj yim thiab tus nqi qis. hom magnesia chrome cib no muaj cov thermal stability zoo, tab sis nws lub zog kub kub yog qis dua li qhov kub hnyiab magnesia chrome cib.
