ELECTRODE HOLDER OF ELECTRIC ARC FURNACE Russian patent published in 2016 - IPC F27D11/10 H05B7/10 

FIELD: metallurgy.

SUBSTANCE: invention relates to electrometallurgy, particularly, to arc melting and its furnaces for melting and heating of metal. Electrode holder consists of head with yoke and contact plate for current supply to graphitized electrode conducting sleeves for transmitting current from flexible cables to contact plate and spring-hydraulic mechanism clamp or release of the electrode, wherein at current-conducting sleeve outer surface along its length there are ribs in form of wave, which width by 2-10 times more than its height.

EFFECT: invention allows to create rigid structure to prevent vibration electrode holder under effect of impact of short-circuit currents at minimum external dimensions of the cross section of sleeve, to reduce active and inductive resistance of current-carrying sleeve and reducing electric losses during operation of furnace by increasing perimeter of electrode holder section.
