Lebenka koroomada sare waxay ka samaysan yihiin magnesia (MgO) iyo chromium oxide (Cr2O3) oo ah maaddooyinka ugu muhiimsan, periclase iyo spinel oo ah qaybaha macdanta ugu muhiimsan ee alaabta dib u soo celinta. leben noocan oo kale ah refractoriness sare, xoogga heerkulka sare, iska caabin ah caabbinta nabaad slag aasaasiga ah, xasilloonida kulaylka fiican, slag acidic sidoo kale waxa uu leeyahay qaar ka mid ah la qabsiga. Maaddada ceeriin ee ugu weyn ee lagu soo saaro leben koromom sare leh waa magnesia iyo chromite sintered. Maaddada ceeriin ee nadiifka ah ee magnesia si ay u noqoto mid aad u sareysa, shuruudaha ka kooban kiimikada chromite waa: Cr2O3: 30 ~ 45%, CaO1.0 ~ 1.5%.
Lebenka koroomada sare waxay inta badan ka kooban yihiin Cr2O3, zirconia monoclinic iyo budada alumina. Sidaa darteed, waxqabadka chromebricks sare wuxuu si dhow ula xiriiraa waxqabadka walxahan. Lebenka dab-damiska ee chrome-ka sare waxa uu ka kooban yahay chromium hemitrioxide 30%, iyo leben koroomeedka sare waxa lagu soo bandhigay caabbinta aashitada iyo alkali, waxaana inta badan loo isticmaalaa lakabka go'doominta, iyo foornooyinka wax dhalada ee aan birta ahayn, iwm.
Leben koroomeed sare leh oo dib u celinaya ayaa laga sameeyay magnesite tayo sare leh iyo chrome ore isku dar ah oo ganaax ah. Marka loo eego dalabaadka kala duwan, hagaajiso waxa ku jira Cr2O3, Dejinta kulaylka alaabta iyo waxqabadka heerkulka sare waa mid lagu qanco. Leben-chrome-sare ayaa si weyn loogu isticmaalaa foornada sibidhka iyo foornada birta ah ee aan birta ahayn iwm.

Leben-chrome High waxaa loo isticmaali karaa in warshadaha biraha, warshadaha walxaha architectures, iyo foornada dhalaalaysa kale non-ferrous, iwm iyo sidoo kale waxaa lagu dabaqi karaa in line sintering aagga sintering ee processing cusub ee qalalan ee foornada sibidhka iyo foornooyinka taangiga galaas sida checkers iyo foornooyinka kale ee warshadaha.
Warshada refractory RS waa shirkad bixisa lebenka refractory sare oo xirfad leh taasoo la aasaasay horraantii 90aadkii ee qarnigii labaatanaad. Warshada refractory ee RS waxay ku takhasustay chrome block sare in ka badan 20 sano. Faa'iidooyinka RS Refractory Factory waa sida soo socota:
