Description

Technical Field

[0001] This utility model relates to the field of electric arc furnace electrode measurement technology, and in particular to an electric arc furnace electrode depth measurement device. Background Technology

[0002] Submerged arc furnaces are key equipment in the metallurgical industry. During the smelting process, due to the consumption of the electrodes themselves and the operators' raising, lowering, pressing and releasing of the electrodes, the smelting parameters such as the electrode end position, arc length, and molten pool surface position are constantly changing, which also affects the balance of the three-phase molten pool power. Furthermore, the electrode insertion depth needs to be controlled within a certain range, and should not be too deep or too shallow, otherwise it is easy to cause fluctuations in the furnace. Therefore, the position parameters of the electrode ends are very important. Currently, domestically developed three-dimensional magnetic field array detection systems can determine the position of the electrode end based on information such as current and liquid level. During the test, the position of the array sensor is adjusted in a timely manner based on the test magnetic field data (position of the electrode end), and sensors are added or removed as necessary to obtain the best data. Therefore, the position of the array sensor needs to be frequently adjusted during the test. To address this issue, we propose a submerged arc furnace electrode depth measurement device.

[0019] See Figure 1-6 A device for measuring the electrode depth of a submerged arc furnace is disclosed. During the production process of the submerged arc furnace, an electric arc is generated between the electrode tip and the molten pool area. The resulting molten alloy accumulates in the molten pool area, with the upper part of the molten pool area being the liquid surface position. When a strong current enters the submerged arc furnace through the electrode, a magnetic field is generated. Based on the magnetic field information, an idealized submerged arc furnace model can be established to determine the electrode tip position. The magnetic field data of the submerged arc furnace is particularly important. This application aims to accurately and rapidly detect and collect the magnetic field information of the submerged arc furnace without making any modifications to the existing submerged arc furnace or affecting its normal production.

In order to ensure the reliability of the power connection, the connecting groove 26 is provided to ensure that the electrode plate 13 is located in the connecting groove 26, thereby ensuring a stable power connection. The connecting groove 26 is provided with an elastically arranged electrode connecting terminal 27. For details, please refer to the connection method between the battery and the electrical device.

The telescopic rod 41 is fixed by the base 42, which can be supported by a stone block or a ground support frame to ensure that the support frame 1 can be supported vertically.

[0023] In this utility model, during assembly, both the connecting frame 3 and the mounting plate 21 are fixed by positioning screws 24, and after being fixed, they are fixed by tightening the positioning screws 24.

[0024] In this utility model, the supporting profile 11 and the connecting frame 3 are C-shaped, which facilitates the measurement and installation of the matrix sensor 22, while providing stable support and a lightweight structure.

[0025] This invention also includes a wireless receiver 5 for receiving data from the wireless transmitter 25. The wireless receiver 5 is paired with the wireless transmitter 25. A computer 6 is used to process the data from the wireless receiver 5. The computer processing program can be found in the prior art.
