Carbon Tamping Paste (CTP)
What is Carbon Tamping Paste? Carbon Tamping Paste(CTP) 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 for the long life of the furnace lining. The Manufacturing Process The manufacturing process for Tamping Paste is the same as for Carbon Electrode Paste,the only difference being the fraction sizes of ECA/CPC which are different for Tamping Paste and the binder content is lower.

What is Carbon Electrode Paste? Carbon Electrode Paste is a self-baking electrode used in submerged arc furnaces for delivering power to the charge mix. Electrode Paste is added to the top of the electrode column in either cylindrical or briquette form. As the paste moves down 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) or Calcined Petroleum Coke (CPC) with Coal Tar Pitch. The Manufacturing Process CPC or ECA is screened to different fractions and stored in hoppers. The various fractions are then weighed using a batching system and taken in a bin. The composition of fractions is taken according to the desired Electrode Paste properties. The resulting aggregate is preheated in a mixer to temperatures up to 180oC and Coal Tar Pitch at 200oC is then added and mixed. The quantity of Coal Tar Pitch added varies depending on desired plasticity. Coal Tar Pitch which is used as a binder in the product is manufactured in-house, using Crude Coal Tar from different sources so as to get the precise Electrode Paste quality.
