Method for controlling ore melting of electric heating furnace by utilizing parametric modeling

Abstract

The invention discloses a method for controlling ore melting of an electric heating furnace by utilizing parametric modeling. The method comprises the following steps: firstly, utilizing the APDL (ANSYS Parametric Design Language) to schedule a process analyzing and processing program of ore melting of the electric heating furnace; completing modeling of the electric heating furnace and obtaining the distribution rules of both the internal temperature field and material phase states through the program; and then judging whether ore needs to be molten to the predetermined state under the parameters according to the distribution rules. According to the invention, the temperature field, the material phase states and the electric heating rule in the whole heating process are shown through parametric modeling, so that experimenters can visually obtain the temperature field and other data in the electric heating furnace under different parameters and take the data as the reference to judge whether ore can be molten to the predetermined state, then the parameters are applied to the control process of the electric heating furnace, and meanwhile, the temperature field and the electrolytic rule are acquired according to the differences of input parameters so as to provide references to both the design and the manufacture of an electrolytic furnace.

[0003] The process of melting ore in an electric heating furnace involves the coupling of multiple heat transfer modes of heat conduction, convection and radiation, and the arrangement of ore materials in the furnace belongs to porous media, and the process of high temperature radiation and phase change in porous media is extremely complicated

Therefore, at present, the experimental research on the heat transfer process in the molten ore electric heating furnace is rarely reported. The design and construction of the electric heating furnace mainly rely on experience, lacking a systematic and scientific theoretical basis; It is also based on experience to set the energizing current and voltage, which will not only cause a waste of electric energy, but also may cause the ore melting to fail to meet the requirements
