  • Patent number: 10045404
    Abstract: An electrode slipping device comprises an upper holder and a lower holder, both holders containing one or more clamping shoes and one or more clamping cylinders in co-operation with the clamping shoes. The clamping shoes are operable between a position where the electrode is clamped and a position where the electrode is unclamped. The clamping cylinder is connected to the electrode holder by first fastening means and to the clamping shoe by second fastening means such that the clamping cylinder can be released from engagement with the holder by unlocking both sets of fastening means.
    Type: Grant

  • Patent number: 9638590
    Abstract: A method and a system for monitoring clamping pressure exerted by a clamping cylinder to an electrode in an electrode slipping device which comprises an upper annular holder ring and a lower annular holder ring, each comprising at least one clamping assembly including a clamping shoe and clamping cylinder arranged in co-operation so that the clamping shoe is forced into pressure contact with the electrode and released from pressure contact with the electrode by the action of the clamping cylinder. The measuring system comprises a force sensor (30) mounted in connection with a pressing piece (22) that transmits the force created by the clamping cylinder to the clamping shoe. The force sensor can be a strain gage (30) mounted in a cavity (25) provided in the pressing piece (22) or a load cell mounted between the pressing piece (22) and the clamping cylinder.

    Abstract: An electrode slipping device comprises an upper holder and a lower holder, both holders containing one or more clamping shoes and one or more clamping cylinders in cooperation with the clamping shoes. The clamping shoes are operable between a position where the electrode is clamped and a position where the electrode is unclamped. The clamping cylinder is connected to the electrode holder by first fastening means and to the clamping shoe by second fastening means such that the clamping cylinder can be released from engagement with the holder by unlocking both sets of fastening means.

  • Patent number: 8506230
    Abstract: A distributor device including a distribution chute that extends inside the tank at an inclined angle for distributing material in the interior of the tank. A rotation frame is rotatable around a vertical central rotation axis (L) and includes a vertical inlet channel extending to the interior of the tank. A circular support frame is horizontally attached to the rotation frame, concentrically in relation to the vertical central rotation axis. A number of support rollers are connected to the tank and the axes of the support rollers are positioned radially with respect to the central rotation axis (L). At least one of the support rollers is as a support roller driving the rotation frame, which support roller the actuator is arranged to rotate. The distributor device includes a counterweight attached to the rotation frame, on the opposite side of the central rotation axis (L) in relation to the distribution chute.

  • Publication number: 20100290866
    Abstract: A distributor device including a distribution chute (3) that extends inside the tank at an inclined angle (a) with respect to the vertical direction for distributing material in the interior of the tank (2). A rotation frame (4) is rotatable around a vertical central rotation axis (L) and includes an essentially vertical inlet channel (5) extending to the interior of the tank (2). The distribution chute (3) is attached to the lower part of said rotation frame, and said inlet channel (5) opens upwardly for receiving any gravitationally moving loose material and downwardly for discharging said loose material to the distribution chute (3) and through the distribution chute further to the tank (1). A circular support frame (6) is horizontally attached to the rotation frame (4), concentrically in relation to the vertical central rotation axis.
