Abstract

Abstract

With the trend of green and low carbon development, the contemporary metallurgical industry pursues high-speed and high-efficiency continuous casting to promote sustainable development. In view of this, a vertical traveling wave magnetic field flow control technology is proposed to optimize and control the flow behavior of liquid metal during continuous casting and overcome the existing technical limitations. The proposed flow control technology can provide theoretical basis and technical support for the green and low-carbon transformation of continuous casting process. In the current research, a 1450 mm × 230 mm continuous casting slab mold is taken as a research object. Firstly, a three-dimensional multi-physical field coupling mathematical model is established for describing the electromagnetic continuous casting process. Secondly, the behaviors of molten steel flow and the steel-slag interface within the slab continuous casting mold under conditions of free magnetic field, vertical traveling wave magnetic field, and single ruler horizontal direct current magnetic field are simulated and investigated. Finally, the effects of these two magnetic field forms on the flow control of molten steel in the mold are compared and evaluated. The results indicate that, in the absence of the magnetic field, the maximum height of the steel-slag interface is 22.3 mm. When applied the current via the single ruler horizontal electromagnetic brake is 1350 A, the maximum height decreases to 18.6 mm. In comparison, when the vertical traveling wave magnetic field reducer applies a current of only 600 A, the maximum height of the steel-slag interface is significantly decreased to 13.9 mm. Based on the results, it can be concluded that the vertical traveling wave magnetic field reducer has more significant flow control advantages than the single ruler horizontal electromagnetic brake with lower energy consumption. The directional electromagnetic force generated by the vertical traveling wave magnetic field can effectively suppress the flow of molten steel in the upper recirculation zone of the mold and stabilize the fluctuation of the steel-slag interface.
