What is Dry Ramming Mass?

Dry ramming mass is a refractory material composed predominantly of high-quality minerals, including alumina, silica, and various bonding agents, which allow for effective shaping and formation under high temperatures. Unlike traditional casting materials, dry ramming mass is used in a dry state, which means it does not require any water or liquid binder to achieve its final form. This unique characteristic makes it ideal for a variety of applications in steel production, particularly in the production of **high-performance steel grades**.

The Composition of Dry Ramming Mass

The effectiveness of dry ramming mass is largely attributed to its composition. Common components include:

• Alumina: Provides high-temperature stability and thermal shock resistance.


• Silica: Enhances the mechanical strength and durability of the ramming mass.


• Graphite: Improves the thermal conductivity and reduces the friction during the ramming process.


• Bentonite Clay: Acts as a binding agent, ensuring that the mass holds together when rammed into shape.
