Dead Burned Magnesia
Dead Burned Magnesia (DBM) is made of finely-selected high-quality raw magnesia ores by different ways of beneficiation, calcined in various types of shaft kilns. With high sintering level and compact structure, DBM is an excellent raw material for producing shaped and unshaped refractory products for a wide range of applications, in electric furnace, converters, ladles, tundishes, as well as for many other Magnesia-based products.
The DBM grades containing 90-93% MgO with heterogeneous structure is produced by selective mining of appropriate grades of Magnesia ore. After hand selection follows single step calcination at over 1600°C in vertical shaft kilns. After post-burning selection, crushing and screening to customized sizes (from lumps to fines) create the various grades, well established for the production of monolithic and low category burnt bricks.
