Abstract (en)
[origin: EP0225548A2] Brick for a bottom electrode, a rear lining or a hearth connection for a.d.c. arc furnace. According to the invention the brick consist of a porous material which has been impregnated by means of immersion into and/or spraying with an organic fluid, such as pitch, tar or a suspension of graphite, soot or the like, or synthetic resin, whereafter the brick has been coked, for example at a temperature of 350 DEG C, thus creating electric current carrying paths containing coal which paths render the brick electrically conductive.
