主 题：Electric arc furnace Titanium slag Magnetohydrodynamic Multi-physical field User-defined function
摘 要：The smelting reduction process of the ilmenite in an electric arc furnace(EAF)is a commonly used technology for producing titanium slag in the *** has particular significance to analyze the velocity-temperature-electromagnetics multi-physical field in an EAF for improving its productivity and reducing energy consumption.A transient three-dimensional mathematical model was developed to characterize the flow,heat transfer,and electromagnetic behavior in a titanium slag *** describing the electromagnetic field and its effects on velocity and temperature distribution in the furnace,magnetohydrodynamic equations and conservation equations for mass,momentum,and energy were solved simultaneously by compiling the user-defined function *** numerical model was verified by comparing with the literature *** results indicate that the Lorentz force is the main driving force of the velocity and temperature ***,the influence of input current and location of electrodes on the multi-physical field distribution was also *** is found that the appropriate range of input current and diameter of pitch circle are about 30,000 A and 3000-3500 mm,*** mathematical model established can characterize the multi-physical field more accu-rately than before,which can provide valuable guidance for the operation improvement and design optimization of the EAF for producing titanium slag.
