Component Specifications

Definition
The carbon aggregate matrix is a critical component within electrode paste columns used in industrial applications such as electric arc furnaces and electrolysis cells. It consists of carbonaceous materials (typically petroleum coke, anthracite, or graphite) bound together with a pitch binder to form a porous, conductive structure. This matrix serves as the primary current-carrying element while maintaining structural integrity under high temperatures and mechanical stresses.
Working Principle
The carbon aggregate matrix operates on the principle of electrical conductivity through interconnected carbon particles, creating a continuous path for current flow. During operation, it withstands thermal expansion and chemical reactions by maintaining a stable porous structure that allows for gas diffusion and thermal management.
Materials
Primary materials include calcined petroleum coke (carbon content >98%), coal tar pitch binder (softening point 80-120°C), and optionally graphite or anthracite additives. Particle size distribution: 0.1-10mm. Binder content: 15-25% by weight.
Technical Parameters
  • Porosity 15-25%
  • Ash Content <5%
  • Compressive Strength 25-40 MPa
  • Thermal Conductivity 10-25 W/m·K
  • Electrical Resistivity 30-60 μΩ·m
  • Maximum Operating Temperature 1500°C
Standards
ISO 8004, ISO 11713, DIN 51904
