Carbon Electrode Paste / Tamping Paste

We are manufacturing high quality carbon electrode paste which is a self baking electrode used in electric/submerged are furnace for delivering power to the change mix. Carbon Electrode Paste is a mix of electrically calcined anthracite or CPC with coal tar pitch.

Carbon Electrode Paste is a self-baking electrode used in submerged arc furnaces.
