摘要： The invention relates to an electrode support arm system for metallurgical furnaces, having an electrode arm (1) having an electrode support arm head (13) implemented as an electrode support device at the front part thereof, designed as a hollow profile having a wall formed at least partially of conductive material having high conductivity, through which a coolant can be guided. According to the invention, flow guide plates and/or displacers are disposed with the electrode support arm (1) implemented as a hollow profile and within the electrode support device implemented on the electrode support arm head (13), by which the coolant flow can be channelized and affected with respect to flow speed, such that optimal flow speeds of the coolant are present at all locations within the electrode support arm (1) and the electrode support arm head (13), wherein highly thermally loaded regions, such as the contact surfaces on the electrode support arm head (13), can be intensively cooled than other, less intensely thermally loaded regions of the electrode support arm (1).
