Carbon Electrode Paste

Carbon Electrode Paste is a self-baking carbonaceous compound used in submerged arc furnaces for delivering energy to the charge mix. Electrode Paste is added to the electrode column, the temperature increase causes the paste to melt and subsequently bake forming a block of electrically conductive carbon. Electrode Paste is essentially a mix of Electrically Calcined Anthracite (ECA) and Coal Tar Pitch.

Tamping Paste

Tamping Paste or Ramming Paste is used in the lining of the submerged arc furnace. It is softened by heating and then applied over the refractory lining of the SAF. Good quality Tamping Paste is essential to the long life of the furnace lining.

Calcined Petroleum Coke

Calcined Petroleum Coke (CPC) is obtained by calcining Raw Petroleum Coke (RPC) at temperature as high as 1400•C. RPC is the by-product of the oil refining process and is derived from the distillation of petroleum crude in delayed cokers. CPC is used in the Aluminium, Graphite Electrode, Steel, Titanium Dioxide and other carbon consuming industries. The specification can be tailored as per the customer’s requirement.
