“…All of these processes are performed in the industrial field without relying on laboratory calibration data. Considering the advantages and characteristics of LFV technology in the measurement of high temperature liquid metal proposed in the previous study [1,24], the method proposed in this study shows that the improved LFV technology in the industrial environment has not only advantages in measurement principle, but also significant advantages in measurement method and reliability.…”

“…During the measurement of Lorentz force, the factor k in equation (1) or the characteristic factor of the LFV system ζ needs to be determined by calibration, such as numerical simulation or benchmark experiments or both together, because of the unavoidable differences between the calibration and the measure practice, for instance, the high temperature, vibration, noise, and measurement environment, the unpredictable errors or even wrong data might be brought in. Therefore, it is particularly necessary to propose a method that can dynamically calibrate the results in real-time on the in-situ measurement site.…”

Our previous study [1-2] reports a non-invasive in-situ measurement technology using Lorentz force velocimetry to quantitatively measure the meniscus velocity of molten steel online. However, effective signal recognition from complex environment noise and determination of zero-point calibration in harsh metallurgical processing is an essentially challenging task and indeed needs further exploration. In this paper, a method of combining double probe arrangement with real-time differential processing technology was proposed, the twin design structure not only enables the measurement of ~mN Lorentz forces, but also has significant characteristics of environmental tolerance. The Lorentz force signal caused by conductor motion can be accurately calculated through a differential method, meaning that the problem of zero compensation in industrial online measurement can be effectively overcome. Moreover, based on the functional correlation between the Lorentz force and the parameter of the conductor to be measured, a method of the probes moving variably and actively and their data difference ratio processing was adopted, so as to achieve dynamic calibration during online measurement. This measurement strategy provides a new approach for LFV to achieve online dynamic measurement and online calibration, and provides technical support for electromagnetic measurement technology towards engineering applications.

“…The flow velocity of molten steel will be slowed down by Lorentz force. Currently, there are several electromagnetic braking techniques, including Local EMBr [5,6], Ruler-EMBr [7], Double Ruler-EMBr [8], Vertical EMBr (V-EMBr) [9,10], and Vertical-combined EMBr (VC-EMBr) [11]. However, for the EMBr system, a large amount of power needs to be consumed.…”

To control well the surface fluctuation of liquid metal in a slab mold, a new type of combined permanent magnets braking system, namely a permanent magnet flow control mold (PMFC-Mold) is proposed by our research group, of which its main feature is that the device can control the flow of molten steel in the mold without additional energy. To observe the fluctuation state of the alloy with the PMFC-Mold, instantaneous surface fluctuations were recorded by a laser level meter and camera. To study the effect of various casting speeds and permanent magnet placement on surface fluctuations, the three measurement points, which were 7, 18, and 36 mm away from the narrow surface of the mold, were selected to record the trend of level fluctuation. Three types of permanent magnet placement were designed by setting the differences between the height center of the permanent magnet and the free surface in the slab mold, which were H1 = 0 mm, H2 = −25 mm, and H3 = −75 mm. The experimental results indicated that with the acceleration of the casting speed, the average height and standard deviation of surface fluctuation at the measurement point increased, but the surface fluctuation pattern remained. When the permanent magnets were arranged at H1 = 0 mm and H2 = −25 mm, the position of the magnetic field was reasonable and the surface fluctuation could be effectively suppressed. In contrast, when the permanent magnets were arranged at H3 = −75 mm, the level fluctuation was intensified.
