    摘要： The invention concerns an electrode for arc furnaces, especially for electrosteel production, comprising a metallic liquid-cooled upper shaft (1) and an exchangeable lower active portion (2) of self-consuming material, particularly graphite, whereby a securing means is provided which is electrically insulated against the current-conducting components (11) of the shaft (1) and said securing means detachably connects the shaft (1) with the active portion (2) as well as holding the contact surfaces of the active portion (23) pressed against the contact surfaces (14) of the current-conducting components (11) of said shaft.To further develop an electrode of this type, which also provides the possibility of rapid and simple disconnection or connection with respect to the shaft (1) and the active portion (2) with a simple design, especially of the area of the active portion on the connection side, the securing device is designed as a clamping means (40; 60) which takes direct effect on the upper end of the active portion (2) in such manner that the clamping force essentially pressure-loads the material of the active portion (2), whereby the physical properties of the material of the active portion (2) are so exploited that no complicated designs are required on the connection side for said active portion (2).

    摘要： Electrode for arc furnaces, more particularly for electrosteel production, also using scrap, comprising a detachable top portion (5) of metal and a replaceable bottom portion (6) of material which is consumed, where appropriate only slowly, having substantially cylindrical shape and being interconnected by a screw nipple (1) or the like and the top portion has a liquid cooling device with a header duct (2) and a return duct (3) and an inner part (16) and an outer part (17) of the top portion are constructed so as to be detachable from each other, so that the inner part (16) contains the liquid conducting chamber with header duct and return duct and the outer part (17) surrounds only a portion of the inner part (16). The electrodes have a reliable coolant conducting system, are easy to maintain and can be simply repaired in the event of mechanical damage while minimizing electrode down times.

    摘要： An electrode for arc furnaces comprising a top portion of metal and a replaceable bottom portion of a material which, when appropriate, is only slowly consumed having a substantially cylindrical shape and being joined each to the other by a screwmounting, for example by means of a screw nipple or the like. The top portion includes a liquid cooling device or means with a header and a return duct, and an insulating coating of high temperature stability. An inner part and an outer part of the top portion are constructed so as to be detachable each from the other. The inner part extends substantially adjacent the screw nipple and at least a portion of the inner part is provided with an insulating coating of high temperature stability, which represents a loosely surmounted moulding.
