摘要： In an arc furnace both of the open-air and submerged arc type an electrode column able to perform angular movements in one or in both directions alternatively about its axis during furnace operations and, at the same time, it can be moved vertically so as to allow the tip level to be changed as usual, as it is necessary in the furnace operation to achieve the best electric arc.
