Numerical Simulation Of Magnetic Fields And Heat Generation Of Slag Bath In Electroslag Remelting Process

With the development of Electroslag metallurgy technology, it is necessary for the relative researchers to care more about remelting process to get a better understanding on its Physical & Chemical phenomena and transmitting process, which aims to optimize process, keep down the coast of production, and increase productive efficiency and product quality. However, which came from the traditional measurements and experimental methods would not provide sufficient data and theory. Under the circumstances, Numerical simulation bloomed into an important method for electroslag remelting research. Therefore, in this thesis, attention is concentrated that the rule of magnetic field and heat generation of slag bath was investigated by numerical simulation based on a small electro-slag furnace offered by a certain company.For the project, two of models were built for magnetic field and heat generation of slag bath respectively which were simulated by ANSYS 11.0 under the given remelting condition.During the experimentation, the value of magnetic flux density is about from 1.904x10-3T to 2.4052x10-2T and the temperature of Heat Generation of Slag Bath is about 1490℃to 1800℃in the region of whole slag bath. The results of Numerical Simulation tally with the data provided by the company which prove the reliability of simulation.Research indicates that the magnetic induction intensity changes in the way of biggest in the ends and smallest in the middle, in general, it is weaken along with the distance increase in the axial position. In the Electro-slag Remelting process, the slag bath temperature field distribution related directly with the electric field distribution and the biggest region of the current density and temperature of electroslag is distrib- uted in electrode lower part. The simulation accuracy could be improved by the deep research to these models. The results got from this project provide a guide for the related experiment and production in fact and give some basic information for investigating the technological optimization of Electro-slag remelting.
