Contact plate for placing in contact with the wall of an electrode of an electro-metallurgical furnace. The contact plate includes an internal channel having an inlet and at least one outlet. The inlet and outlet are respectively linked to an external intake duct and to at least one external duct for discharging a fluid. An elongate hole (16) has an elongate partition (35) which has opposing elongate edges (39) adjacent to opposing elongate zones (33) of the elongate hole so as to define, in the hole, elongate spaces (16a-16b) on either side of the elongate partition. The elongate partition defines a connecting passage (41) between the elongate spaces and link holes (29) communicating with the elongate spaces being formed at a distance from the connecting passage. The elongate spaces form portions of the internal channel (59).

Provided is a pressure ring assembly for contact shoes in an electrode system of an electric arc furnace provided with at least one electrode column assembly. The electrode column assembly comprises a contact shoe ring formed of a plurality of contact shoe elements, a pressure ring formed of a plurality of pressure blocks, and a heat shield formed of a plurality of heat shield segments. An elongated groove is formed on both substantially vertical side edges of each pressure block, and an elongated lock bar is placed in the grooves of two adjacent pressure blocks to join said pressure blocks with each other. The form of the lock bar essentially matches to the form of the grooves of said two adjacent pressure blocks. Each lock bar is locked in place in the grooves by fastening bolts through holes in the pressure blocks.

Metallurgical assemblies may include a metallurgical vessel. The assemblies may include an anode stack positioned within the metallurgical vessel. The assemblies may include a structure positioned outward from a peripheral surface of the anode stack. The assemblies may include a clamp seated atop the structure. The clamp may be engageable with the anode stack. The clamp may include a body having an inner surface defining an open interior. The anode stack may be within the open interior. The clamp may include a clamping surface coupled with the body that is moveable relative to the inner surface to selectively engage the anode stack. The clamp may include a tightening mechanism that is operably coupled to the clamping surface and that adjusts a position of the clamping surface. The clamp may include an electrically insulating member between the body and the support structure to electrically isolate the clamp from the structure.

An electrode clamping device and a power transmission vehicle. The electrode clamping device includes a first supporting frame; at least one electrode clamp for clamping a graphite electrode; and a flexible connecting piece for suspending the electrode clamp under the first supporting frame; the electrode clamp is connected with the first supporting frame through a flexible connecting piece. The flexible connecting piece can make the electrode clamp adjust adaptively with the change of the position and deformation of the graphite electrode, so as to adapt to the complex deformation of the displacement and deflection of the graphite electrode in different directions and degrees, and the connection between the electrode clamp and the graphite electrode is stable and reliable. In addition, only one part of the flexible connecting piece is used to realize the self-adaptive function of the electrode clamp, and the structure is simple and reliable.
