Description

Carbon Electrode Paste is produced by putting petroleum coke and asphalt into melting tank to dehydration, melt, then adding them into kneading pot to kneading, molding and sintering.

Fully automated batching, crushing, mixing, kneading, molding, quality assurance, strict control of ash content, volatile, ensure low resistance and high strength.

Characteristics

  1. Lower ash content;
  2. Acurate dosing and stable volatile content;
  3. Good electric and thermal conductivity and the sintering speed apropriate to that of consumption of working end;
  4. Smelting at lower temperature with certain fluidity and homogeneous composition;
  5. High resistance to high temperature, oxidation and thermal shock, low resistivity and high mechanical strength after sintering.

Application Areas

  1. Submerged arc furnace
  2. Ferrosilicon alloy smelting
  3. Siliconmanganese alloy smelting
  4. Yellow phosphorus smelting
  5. Si-Ca-Ba alloy smelting
