Ramming, gunning, and spraying masses are unshaped refractories designed for in-situ installation where joint-free linings, rapid repairs, and precise thickness control are required.
Champion Ceramics offers a comprehensive range of magnesia- and silica-based ramming masses, gunning materials, and spraying mixes engineered for high-temperature metallurgical applications.
These products are formulated to develop strength through chemical bonding or controlled ceramic sintering, depending on application requirements, and are capable of withstanding high service temperatures, slag attack, and repeated thermal cycling.
Graded particle size distributions, controlled chemistry, and optimized bonding systems ensure reliable compaction, adhesion, and dimensional stability across different furnace zones and installation methods.
