Problems solved by technology
[0006] 1) As the vacuum arc remelting process progresses, the arc area increases accordingly, and the existing technical solutions cannot track the axial position of the arc in real time, so the predicted arc position will have a large error
[0007] 2) The final prediction is the position of the center of mass of multiple arcs, and it is not clear how to determine the distribution positions of all arcs

The invention discloses a device and a method for measuring arc space distribution in the vacuum arc remelting process. The device comprises a sensor arrangement frame, an automatic lifting unit, Hall effect sensors, thermocouples, a multi-layer lifting coil and a consumable electrode. The sensor arrangement frame is arranged on the outer side of an electric arc furnace body in a sleeving mode. The multi-layer lifting coil is slidably mounted on the sensor arrangement frame. The plurality of Hall effect sensors are fixedly mounted on the multi-layer lifting coil in layers and columns respectively, and the plurality of thermocouples are longitudinally arranged on the wall of the electric arc furnace body. The multi-layer lifting coil is connected with an executing mechanism of the automatic lifting unit through a bracket. The consumable electrode is suspended in the furnace body and at the upper part of a cast ingot. The real-time arc distribution in the vacuum arc remelting process can be measured, and on the basis of the measurement result, how to control the arc distribution to improve the vacuum arc remelting process can be further studied, and the product ingot casting quality is improved.
Description
technical field [0001] The invention relates to a vacuum arc remelting technology, in particular to a device and method for measuring the spatial distribution of arcs in the vacuum arc remelting process. Background technique [0002] As the final step of the high-end alloy vacuum induction melting-electroslag remelting-vacuum arc remelting (VIM-ESR-VAR) triple process, the vacuum arc remelting process has been widely used in the preparation of superalloys, titanium alloys, stainless steel and high-strength steel And other forgings, and play a decisive role in the quality of product ingots. However, the ingots produced by the VAR process still have various defects such as black spots, white spots, and annual rings. These defects greatly reduce the service performance and service life of the ingots, and even lead to their direct scrapping. [0003] A large number of research works have shown that the spatial distribution of the arc between the ingot and the consumable electro...
