Abstract: In the production of an electrode for an arc furnace from a hardenable electrode paste and in which the arc current is fed to the electrode via a current supply unit, an electrode heater is arranged, in the direction of feeding down of the electrode into the furnace upstream of the current supply unit, said electrode heater supplying thermal energy to the electrode paste for the purpose of baking the latter, the formation of the electrode from the paste taking place in a casing which is not consumed in the arcing.

Abstract: A rolling mill having a roll stand with back-up rolls and two cylindrical work rolls. The work rolls have roll-pass grooves associated in pairs with different roll-pass areas. The driving mechanism of the rolling mill is coupled to the back-up rolls which exercise constant pressure on the work rolls during rolling so that these are in hard mutual contact and rotate with the back-up rolls. The work rolls are axially displaceable in the roll stands between the back-up rolls when the latter are open so that a desired roll-pass groove can be positioned with its center line coinciding with the central plane of the rolling mill.
