ITEM 26 – Torque Station for Graphite Electrodes

An intelligent hydraulic machine for the assembly of graphite electrodes:

• Once the clamps are closed they cannot be opened unintentionally (any oil leakage does not involve the mechanical screw). Clamps can hold the electrode column for extended periods.
• The U-shape gives the possibility of approaching very easily sideways to the column with the new electrode.
• The side opening allows the lifting plugs to be removed quickly and easily.
• A lever-clamping collar and a cylinder are supplied, to achieve a correct assembly and set the required torque.
• This system allows the unscrewing of previously jointed electrodes.
• The electrode joining operation is driven by a PLC and requires only one operator.
• Automatic tightening sequence is provided.
• A display shows the tightening torque achieved at the end of the operation.

Standard Version

• Manual distributor for clamps opening and closing.
• Tightening push buttons to control the machine.
• Digital display for instant torque monitoring.

Gold Version

Provided with a Touch Panel which allows to:

• control the movements of the station (all push buttons are digital)
• show the information about the device
• show all the information about the tightening process, including the last torque reached
• diagnostic features including alarm messages, input and output states
• the remoted electrical board could be installed far from the electrodes area and, if necessary, interlocked with a restricted area to enhanced safety
