Ramming Mass – High-Density Monolithic Refractory
Ramming mass is an unshaped refractory material used for lining induction furnaces, ladles, and other high-temperature equipment. It is applied dry and compacted into place, forming a dense, erosion-resistant lining that withstands thermal shock, mechanical stress, and chemical attack.

Key Properties of Ramming Mass
1. High-Temperature Resistance: Withstands temperatures up to 1,750°C.
2. Density: Typically ranges from 2,500–3,100 kg/m³, ensuring durability.
3. Thermal Conductivity: Optimized for heat retention and slag resistance.
4. Chemical Composition: Available in silica-based, alumina-based, and magnesia-based formulations.
5. Application Method: Installed dry and compacted using pneumatic rammers or manual tamping.
Types of Ramming Mass
Silica-Based Ramming Mass: Used in induction furnaces for steel melting.
Alumina-Based Ramming Mass: Ideal for non-ferrous metal industries.
Magnesia-Based Ramming Mass: Suitable for basic slag environments in steelmaking.
Neutral Ramming Mass: Designed for versatile applications in high-temperature industries.
Applications of Ramming Mass
Induction Furnaces: Forms a protective lining against molten metal erosion.
Ladle & Tundish Repairs: Used for patching worn-out refractory linings.
Electric Arc Furnaces (EAF): Provides thermal insulation and slag resistance.
AOD Converters: Enhances durability in stainless steel refining.
