Cold Ramming Mass
Easy Installation
Can be applied directly at room temperature without heating, reducing construction time and improving installation efficiency.
Excellent Erosion Resistance
High sintering strength and superior resistance to thermal shock, mechanical impact, and molten slag erosion ensure long-lasting performance.
Stable Operation
Maintains structural integrity under severe operating conditions, improving furnace stability and reducing maintenance frequency.
