Ramming mass is a refractory material used for lining induction furnaces, electric arc furnaces, and other high-temperature equipment where it’s crucial to have a stable and heat-resistant lining. It’s made from a mixture of refractory aggregates, binders, and additives, which are carefully selected and blended to create a material that can withstand extreme thermal and mechanical stresses.

Ramming mass gets its name from the method used for installation: it’s “rammed” or compacted into the lining using specialized tools. This results in a tightly packed and uniform lining that is resistant to cracking, erosion, and thermal cycling.

The choice of ramming mass composition depends on the specific requirements of the application. Different types of aggregates and binders can be used to create ramming masses with varying properties, such as resistance to slag attack, thermal shock, or mechanical wear.

Ramming mass plays a critical role in maintaining the efficiency and longevity of high-temperature equipment by providing a durable and heat-resistant lining that withstands the harsh conditions of metal melting, alloying, and other industrial processes.
