Definition of Ramming refractories

Refractarios de apisonamiento refer to amorphous refractory materials that are constructed by ramming (manual or mechanical) and hardened under heating above normal temperature. It is made by mixing refractory aggregates, powders, carpetas, admixtures with a certain grade, and adding water or other liquids.

Refractories ramming mass is a bulk material composed of a high proportion of granular materials and a low proportion of binders and other components, or even all of granular and powdery materials, which needs to be constructed by strong ramming.

Other amorphous products

• Cemento refractario
• Refractory plastic
• Mortero refractario
• Refractory aggregate
• bauxita refractaria
• Calcinable refractario

characteristics of refractories

Physical characteristics

• Resistencia a altas temperaturas: Refractory materials can withstand temperatures much higher than conventional building materials, and their refractoriness can usually exceed 1580℃.
• Deformation resistance: Under high temperature conditions, refractory materials can maintain their shape and dimensional stability and are not prone to softening or deformation.
• Resistencia a la corrosión: Refractory materials have the ability to resist chemical erosion and can maintain their structural integrity when exposed to corrosive substances.

Chemical characteristics

• Alto punto de fusión: Refractory materials usually have a high melting point, which means that they can be used for a long time at temperatures close to their melting point without melting.
• Estabilidad química: Refractory materials can still maintain their chemical properties stable at high temperatures and are not easy to react with other substances.

Process characteristics

• Processability: Refractory materials can be made through different processes, such as sintering, casting, etc., in order to adapt to different use requirements.
• Resistencia al desgaste: Refractory materials usually have good wear resistance and can be used for a long time in environments with high friction.

Use characteristics

• Anti-oxidation performance: Some refractory materials have good anti-oxidation performance, which can extend the service life in high-temperature oxidizing environments.
• Thermal insulation properties: Refractory materials used in the construction industry also have good thermal insulation properties, which can effectively reduce heat transfer.
