SET OF ELECTRODE HOLDERS Russian patent published in 2003 - IPC

FIELD: electrometallurgy; electric arc and electric slag furnaces. SUBSTANCE: set of electrode holders for three-phase electric arc and electric slag furnaces has heads with contact clamps passing current to electrodes, electrode clamping mechanism, tubular buses mounted through insulation on single bearing frame that ensures joint displacement of electrodes; head with intermediate-phase contact clamps is mounted above heads with extreme-phase contact clamps and their projection onto vertical plane crossing axis of extreme phases forms isosceles triangle. Bearing frame is made in the form of isosceles triangle carrying at their vertexes tubular buses and heads with contact clamps; heat shield secured under the latter functions also as maintenance floor. Actuators of electrode clamping mechanisms are disposed on bearing frame side opposite to that carrying heads with contact clamps and electrode clamping mechanisms; actuators and electrode clamping mechanisms are interconnected through control rods and levers. EFFECT: reduced consumption of lining materials and short- circuit inductance reactance; enhanced useful power and output of furnace; reduced cost of metal produced. 3 cl, 4 dwg
