Ramming Masses are refractory materials used for lining furnace walls, hearths, and other high-temperature industrial equipment. They are designed to withstand extreme heat, chemical corrosion, and mechanical stress, making them an essential component of many industrial processes.

Ramming Masses are made from a variety of raw materials, including high-purity quartz, calcined magnesite, bauxite, and silicon carbide. The raw materials are mixed with a binder, such as clay or high-temperature cement, and then rammed into place using pneumatic hammers or other mechanical tools.
