Perfect electrodes in submerged arc furnaces are absolutely necessary for a successful production. Mechanical and electrical contact between casing and soederberg paste must be perfect to assure an even current distribution in the electrode. To achieve the required paste properties the selection of the raw materials as well as the production process and control are on a very high level.
- based on anthracite, petcoke and graphite
- various quality grades available, depending on the furnace characteristics
- standard and high purity
