Refractory Ramming Mass Manufacturer
High Performance Dry Ramming Mass for Induction Furnaces, Coreless Furnaces and High Temperature Furnace Linings
Refractory ramming mix is a type of monolithic refractory material that is compacted and shaped through external forces (manual or mechanical ramming and vibration) and hardens upon heating above room temperature. It is classified into three types: acidic, neutral, and basic. High-quality raw materials such as high-alumina bauxite, corundum, spinel, fused magnesia, and high-purity magnesia are used as the primary components. Various binders and specially formulated fine powders are added and precisely blended to achieve the desired properties.
Refractory ramming mass is an unshaped refractory material composed of selected refractory aggregates, fine powders, and high-performance binders. It is installed by ramming or vibration to form a dense, seamless furnace lining capable of withstanding extremely high temperatures and thermal cycling.
Compared with conventional refractory bricks, ramming mass provides a monolithic lining with fewer joints, reducing heat loss and minimizing the risk of cracking or slag penetration. It is widely used in induction furnaces, coreless melting furnaces, channel furnaces, and other high-temperature equipment.
Available in acid, neutral, and customized formulations, refractory ramming mass can be tailored to different furnace types, molten metals, and operating conditions.

FAQ
Q:What is refractory ramming mass?
A:Refractory ramming mass is an unshaped refractory material installed by ramming to create seamless, high-temperature furnace linings.
Q:What is the difference between acid and neutral ramming mass?
A:Acid ramming mass is silica-based and commonly used for cast iron melting, while neutral ramming mass is alumina-based and suitable for steel melting applications.
Q:What temperature can ramming mass withstand?
A:Depending on the formulation, refractory ramming mass can withstand temperatures ranging from 1600°C to 1750°C.
Q:How is ramming mass installed?
A:It is compacted layer by layer using pneumatic or manual ramming tools to form a dense monolithic lining.
Q:Can ramming mass be customized?
A:Yes. ZKD offers customized formulations based on furnace type, molten metal, operating temperature, and slag conditions.
