Study and Development on Numerical Simulation for Application of Electromagnetic Field Technology in Metallurgical Processes

The application of electromagnetic fields is an important way to control the physical and chemical changes of heat transfer, mass transfer, fluid flow and solidification in metallurgical and material preparation processes. It is of great significance to improve the production efficiency and product quality. In this paper, the authors summarize the research contents and progress of numerical simulation on several typical applications of electromagnetic technology in metallurgical fields in recent years, including the electromagnetic steel-teeming technology using induction heating and induction heating technology of a tundish, the applications of electromagnetic force such as the electromagnetic swirling technology in submerged entry nozzle, the soft-contact mold electromagnetic continuous casting technology and the electromagnetic metallurgical technology for tundish, the influence and control of electromagnetic force on solidified structure evolution, and also the electromagnetic cold crucible technology with comprehensive utilization of induction heat and electromagnetic force. Numerical simulation, as an important research method, is a very important tool in finding out the mechanism and rules of electromagnetic fields during metallurgical and material preparation processes to predict, analyze, and optimize metallurgical processes.
