Magnesia-based ramming mass is a monolithic refractory material primarily composed of magnesia (MgO). It is widely used for lining furnaces, particularly in the steelmaking industry. This dry, bulk material is rammed into place during construction or repair, providing excellent resistance to high temperatures, thermal shock, and corrosion caused by molten metals and slags.
Magnesia ramming mass is produced using sintered or fused magnesia as the main component, combined with fine powders, binders, and sintering aids. It is installed by compacting (ramming) the material into place, either manually or with mechanical tools.
