Embodiment 1

[0024] Such as figure 1 As shown, a LF furnace electrode testing system includes an electrode regulator 5, a lifting mechanism 11, an electrode 14, a coil 13 and a controller. The electrode 14 is connected to the lifting mechanism 11, and the electrode 14 passes through the coil 13, and the coil 13 is also electrically connected to a first feedback module, and the electrode 14 is also electrically connected to a second feedback module, both the first feedback module and the second feedback module are connected to the electrode regulator 5 with electrical signals, and the controller is connected to the electrode regulator 5 with electrical signals .

[0025] Both the first feedback module and the second feedback module are integrators 9 .

[0026] The electrode regulator 5 is also electrically connected with a proportional valve 8 , and the proportional valve 8 is connected with the lifting mechanism 11 .

[0027] The controller includes a data collection module 16, an interp...

Embodiment 2

[0033] On the basis of Example 1, such as figure 1 with figure 2 Shown, a kind of LF furnace electrode testing system test method, comprises the following steps

[0034] Historical data input, input the historical data collected in the actual production into the controller,

[0035] Historical data reading, the controller reads the data value at a certain moment in the historical data, and transmits it to the electrode regulator 5, and the electrode regulator 5 determines the position of the electrode 14, and the controller sends a signal to the lifting mechanism 11 according to the position of the electrode 14, Drive the lifting mechanism 11 to move, so that the electrode 14 moves to a designated position;

[0036] Position feedback, the first feedback module and the second feedback module return the real-time measured data to the electrode regulator 5, and the electrode regulator 5 determines the designated position of the electrode 14 according to the actual data. If the...

Embodiment 3

[0047] On the basis of Example 2, such as figure 1 with figure 2As shown, the collected historical data is input into the interpretation module 2, and the interpretation module 2 converts the historical data into a format readable by the electrode regulator 5, and then inputs it to the electrode regulator 5.

[0048] The historical data includes arc current and arc voltage, and the time corresponding to the arc current and arc voltage.

[0049] In the cyclic test stage, the clock judging module 3 performs a cyclic timing trigger to judge whether the test time increment reaches the clock value, if so, reads new historical data, and transmits it to the data writing module 4, and the data writing module 4 Transfer to the electrode regulator 5, otherwise return to wait.

[0050] The data collection module 16 also collects and saves real-time data during actual operation.

[0051] The historical data is stored in the acquisition data module 16, and the interpretation module 2 r...

Abstract

The invention discloses an LF furnace electrode test system and a test method. The system comprises an electrode regulator, a lifting mechanism, an electrode, a coil and a controller, wherein the electrode is connected to the lifting mechanism, the electrode passes through the coil, the coil is also electrically connected with a first feedback module, the electrode is also electrically connected with a second feedback module, the first feedback module and the second feedback module are in electric signal connection with the electrode regulator, and the controller is in electric signal connection with the electrode regulator. The non-working LF furnace is driven to work according to the actual working condition through historical data to test the electrode regulator, so that the field debugging time is shortened, the equipment stability is improved, the equipment debugging and maintenance cost is reduced, and the equipment production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of refining, and in particular relates to an LF furnace electrode testing system and testing method. Background technique [0002] The LF furnace electrode regulator is the core controller and an important part of energy saving in the LF refining furnace system. How to realize the undistorted, real-time and effective testing of the LF furnace electrode regulator according to the actual working conditions on site is the key to the LF refining furnace system. [0003] However, the existing adjustment method is to adjust according to the actual situation while allowing the LF refining furnace system to produce. Since the LF furnace has the characteristics of fast production rhythm, fast heating speed, and high heating efficiency in the steelmaking process, it is difficult to adjust on-site construction, and the adjustment during the production process will cause a lot of waste of production resources due to sto...
