GRAPHITE ELECTRODE Russian patent published in 2015 - IPC H05B7/07

Abstract RU 2559832 C2

FIELD: process engineering.

SUBSTANCE: invention relates to graphite electrode of electric arc furnace. Graphite electrode resists oxidation thanks to modification of external characteristics of cylindrical surface (14). External cylindrical surface can be modified so that it incorporates textured section (16) to improve the water flow by minimising the water absorption. Optionally, flexible graphite ply or multiple particles of exfoliated graphite can be fitted on external cylindrical surface of electrode body (10).

EFFECT: decreased oxidation of graphite article.
