emi-Bonded MgO-Chrome Bricks, manufactured from fused magnesite and fused MgO-chrome sand, are fired in ultra-high-temperature furnaces after high-pressure pressing.
Direct bonding rate is high with good particle combination, good volume stability at high temperature and excellent high temperature strength. It has been widely used in RH, AOD, VOD, smelting furnaces, melting furnaces and refining furnaces.
