Dry ramming mass is a refractory material used in high temperature industrial applications, typically used for lining high temperature furnaces, smelting furnaces and other similar equipment. It is
a dry powder material that does not require the addition of water or other liquids and is applied by physical tamping or compaction.
Features of Dry ramming mass:
High temperature tolerance: Able to withstand extremely high temperatures, maintain good refractory properties, and avoid melting or decomposition.
Excellent impact resistance: Able to withstand impact and friction during high temperature operation.
Thermal stability: Strong adaptability to temperature fluctuations, preventing cracks caused by temperature differences.
Chemical stability: Good resistance to erosion by molten metals or chemicals.
Acid Dry ramming mass:
After sintering in the first heat of kiln baking, the conversion rate of α-phosphor quartz is high, and the time of kiln baking is short. In addition, it has excellent volume stability, thermal shock resistance and high strength at high temperature.
Neutral Dry ramming mass:
Neutral dry ramming mass has the characteristics of easy construction, hardening at room temperature, high strength at high temperature, low thermal expansion and shrinkage, and strong resistance to solution erosion.
Alkaline Dry ramming mass:
Alkaline dry ramming mass has the advantages of good volume stability at high temperature, erosion resistance, abrasion resistance, good thermal shock resistance, and high refractoriness under load.
