Production of dense carbon aggregates from carbonaceous materials for varied volatile contents for use in carbon products in general and soderberg paste in particular

Abstract

The paper describes the various process details of preparing dense carbon aggregates from indigenous raw materials and production of Soederberg paste from the carbon aggregates. The properties of dense carbon aggregates obtained under optimum conditions have been furnished. The detailed study of the green and fired properties of the imported electrode pastes and the compositions developed at the National Metallurgical Laboratory has shown that the NML made products are well comparable with the French and Norwegian pastes.
