Ramming Mass

Product Description  

Ramming Mass is a dry refractory material used for lining induction furnaces in steel and iron melting operations. It is applied by ramming around the furnace coil to form a dense, monolithic lining capable of withstanding high temperatures, thermal shock, and chemical attack from molten metal and slag. 

High-quality ramming mass ensures uniform heat distribution, low thermal expansion, and strong sintering properties, which contribute to longer furnace life and reduced maintenance downtime. It plays a critical role in maintaining furnace efficiency, metal purity, and stable melting performance. 

Manufactured using high-purity quartz or alumina-based materials, ramming mass offers excellent refractoriness, low alkali content, and superior resistance to erosion.

Applications 

• Induction furnace lining 
• Steel melting plants 
• Alloy steel production 
• Iron foundries 
• Medium and high-frequency induction furnaces 

Advantages 

• Extended furnace lining life 
• Improved thermal stability 
• Reduced power consumption 
• Low metal contamination 
• Strong sintering and crack resistance 

Types of Ramming Mass 

Acidic Ramming Mass Silica-based lining material primarily used for carbon steel and alloy steel melting applications.

Neutral Ramming Mass Alumina or spinel-based refractory suitable for melting stainless steel and special alloys where chemical neutrality is required.
