Product Description:

INTRODUCTION

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.
