Carbon Electrode Paste

Listing ID #192386

CPC received from our own plant or ECA received from overseas suppliers is screened to different fractions and stored in different hoppers. The various fractions are then weighed using electronic batching system and taken in a bin. The proportions of the fractions are fixed according to the desired properties of electrode paste. The total aggregate is then preheated in sigma type mixer upto 180^oC and then liquid coal tar pitch is added at 200^oC and mixed. Depending on desired plasticity of Electrode paste, quantity of liquid Coal Tar is added. Coal Tar pitch is used as a binder.
