Dead Burnt Magnesite (DBM) is a widely used refractory material. The finished product is low in Silica and high in Iron which is suitable for hot fettling of Furnaces and ideal for manufacturing Monolithic which helps in quick sintering because of high Iron content.
Dead Burnt Magnesite is produced in a vertical shaft by sintering raw magnesite at a controlled high temperature. DBM is chemically inactive and extremely heat resistant and therefore is highly recommended for EAF's. It is the main raw material for manufacturing basic refractories including gunning masses, ramming masses, for tundish linings and in hot fettling as fettling mass.
