Electrode device

Abstract

The invention discloses an electrode device, comprising an electrode main body, an upper band-type brake, a lower band-type brake, a lifting mechanism and a conductive mechanism. The upper band-type brake is used for tightly holding and releasing the electrode main body; the lower band-type brake is used for tightly holding and releasing the electrode main body, located below the upper band-type brake, installed on the lifting mechanism and moves together with the lifting mechanism; and the conductive mechanism electrically contacts with the electrode main body and synchronously moves along with the lifting mechanism relative to the electrode main body. The electrode device is convenient to compensate the consumption quantity of the electrode and has high operation efficiency.

Description

technical field [0001] The invention relates to an electrode device, in particular to an electrode device for an electric furnace. Background technique [0002] The electric furnace is a widely used metallurgical equipment. The electrodes of the electric furnace are set above the furnace body and extend into the electric furnace. In order to adapt to different working conditions, the depth of the electrodes inserted into the furnace body needs to be adjusted frequently, so the electrodes of the electric furnace are usually movable. [0003] The traditional electric furnace usually uses a hoisting device to lift the electrode, and the cables of the hoisting device are hung on both ends of the electrode holding device, so as to realize the lifting of the electrode. In addition, there is also an electric furnace that uses a spiral lifting device to lift the electrode. The electrode is fixed on the spiral lifting device as a whole, and the electrode moves up and down with the li...

Problems solved by technology

With the use of the electrode, the lower end of the electrode inserted into the furnace body will be continuously consumed, and the length inserted into the furnace body will become shorter. At this time, only relying on the lifting device to lift the electrode cannot meet the requirements, and the electrode needs to be lowered relative to the lifting device as a whole to compensate for the consumption of the electrode.

[0004] The lifting device and conductive device of the traditional electrode are fixed relative to the electrode. The electrode cannot move relative to the lifting device, and the conductive device cannot move relative to the electrode. Therefore, the maximum electrode length that can be inserted into the furnace body of the electric furnace is fixed. When the electrode is used When a certain amount is consumed, the requirement cannot be met

For this reason, it is necessary to cut off the power, disconnect the connection between the electrode and the power supply device at the same time, re-adjust the relative position of the electrode and the power supply device, and then fix the power supply device again, clamp the electrode with the power supply device, that is, compensate the electrode by manually pressing and releasing. Therefore, the operation is complicated, the cost is high, the furnace needs to be shut down, the efficiency is reduced, and it is also dangerous
