Automatisches System zum Verbinden von pneumatischen und hydraulischen Schläuchen mit einer Lichtbogenofenelektrode

System for connection of pneumatic and/or hydraulic hoses (11) on composite electrodes (12) for arc furnaces, the electrodes (12) comprising at least one hollow adapter (13) associated at the lower part with a replaceable graphite element (14), the electrode (12) cooperating with an electrode-holder arm (15) and being displaceable axially in relation to that electrode-holder arm (15), the hoses (11) being associated at one end with a first connection assembly (18a) associated with supporting means (17), the adapter (13) including a solidly attached second connection assembly (18b) mating functionally with the first connection assembly (18a), the first (18a) and second (18b) connection assemblies comprising mating connecting elements (19a, 19b) equipped with elements to interrupt the flow of the fluid which can be temporally actuated, the supporting means (17) associated with the first connection assembly (18a) having a first inactive position temporally solid with the electrode-holder arm (15) and a second working position released from the electrode-holder arm (15) and temporally solid with the second connection assembly (18b) associated with the adapter (13), the transition from the first inactive position to the second working position of the supporting means (17) taking place according to the position of the electrode (12) in a defined position of engagement/disengagement.
