Refractory ramming mass, also known as refractory tamping mass or ramming mix, is a refractory material used for lining the furnace or other high-temperature applications.

General steps for using refractory ramming mass:

1. Surface Preparation: Before applying refractory ramming mass, the surface needs to be clean and free from any loose materials, dust, or debris. Remove any old refractory lining or residual materials, and ensure the surface is smooth and dry.

2. Mixing: Follow the manufacturer's instructions to prepare the refractory ramming mass. Typically, you need to mix the ramming mass powder with the appropriate amount of water to achieve the desired consistency. Use a clean mixing container and mix thoroughly to ensure a homogeneous mixture.

3. Application: Start applying the ramming mass to the furnace lining. Use a tamping rod or a suitable tool to pack the ramming mass tightly and evenly against the furnace walls. Begin from the bottom and work your way up, ensuring proper compaction of the material to eliminate any voids or air pockets.

4. Compaction: As you apply the ramming mass, use a mallet or pneumatic hammer to gently tap the surface to compact the material and remove any potential voids. Continue to compact and layer the ramming mass until you achieve the desired thickness and coverage.

5. Finishing: Once the ramming mass is applied and compacted, inspect the lining for any gaps or irregularities. Use additional ramming mass to fill any gaps, ensuring a solid and uniform lining. Smooth the surface with a trowel or other suitable tool for a proper finish.

6. Curing: Allow the refractory ramming mass to cure and dry according to the manufacturer's instructions. This typically includes a drying period where the temperature is gradually increased to remove any remaining moisture from the material. Follow the recommended curing schedule to ensure proper bonding and strength development.

Note that specific procedures and requirements may vary depending on the specific refractory ramming mass and application. It is important to consult the manufacturer's guidelines and recommendations for the particular product are using.
