Product Overview
What Is Cold
Ramming Paste
Cold Ramming Paste is a ready-to-use, carbon-based refractory material composed of calcined anthracite, graphite, and coal tar pitch binders. Unlike hot ramming paste, it is applied at ambient temperature, eliminating the need for preheating equipment and significantly reducing installation complexity.
Designed for the construction and repair of hearth linings, taphole areas, and bottom linings in electric arc furnaces (EAF), submerged arc furnaces (SAF), and ferroalloy furnaces, it delivers exceptional thermal conductivity, chemical resistance, and structural integrity under extreme operating conditions.
Our formulation ensures superior bonding strength, minimal porosity after sintering, and outstanding resistance to thermal shock and slag penetration -- extending furnace campaign life and reducing maintenance downtime.
