Home / Tamping Paste

Overview

Tamping Paste, also referred to as Ramming Paste or Lining Paste, is a carbonaceous lining material used in Submerged Arc Furnaces (SAF). When heated, the paste becomes workable and is applied over the refractory lining to form a dense, joint-free layer. Consistent quality and controlled application of tamping paste are critical for achieving effective thermal insulation and extended furnace lining life.

  • Selection and processing of carbonaceous materials
  • Controlled use of soft pitch as a binder
  • Optimized particle size distribution for effective compaction
  • Optimized particle size distribution for effective compaction
  • These parameters ensure consistent performance under demanding furnace operating conditions.

Quality Parameters

  • These parameters ensure consistent performance under demanding furnace operating conditions.
  • Low binder content to enhance heat resistance and minimize volatilization
  • Low binder content to enhance heat resistance and minimize volatilization
  • Low binder content to enhance heat resistance and minimize volatilization
  • Working temperature during tamping is a key performance factor- Recommended tamping temperature: 130°C – 150°C
