Abstract—

Using mathematical three-dimensional modeling methods, the features of the distribution of electric and thermal fields within the volume of the melt of the casting alloy A356 have been established during its treatment with electric current using parallel electrodes. It has been found that the geometry of the electrode system qualitatively and quantitatively determines the effect of electrothermal action on the melt during treatment with direct current. It has been shown that the depth of immersion of electrodes with an uninsulated lateral surface does not have an active influence on temperature processes during conductive electrocurrent treatment. The qualitative and quantitative data obtained for systems with uninsulated electrodes correspond to the results of experimental studies. It has been shown that changing the spatial geometry of the arrangement of electrodes with insulated lateral surfaces significantly affects the spatial distribution of electric and thermal fields, resulting in a more than threefold quantitative change in the characteristics of these fields within the melt volume. The method for controlling the processes of conductive electrothermal treatment of melts based on spatial changes in the type of electrode system does not require additional costs and can be carried out directly during the treatment process.

熔体导电电流处理过程中电场和热场分布特征的三维建模

摘要:采用数学三维建模方法，建立了A356铸造合金在平行电极电流处理过程中熔体内部电场和热场的分布特征。在直流电处理过程中，电极系统的几何形状定性和定量地决定了电热作用对熔体的影响。研究表明，在导电电流处理过程中，非绝缘侧表面电极的浸泡深度对温度过程没有积极影响。非绝缘电极系统的定性和定量数据与实验研究结果相一致。研究表明，改变具有绝缘侧表面的电极排列的空间几何形状会显著影响电场和热场的空间分布，导致这些场在熔体体积内的特性发生三倍以上的定量变化。基于电极系统类型的空间变化控制熔体导电电热处理过程的方法不需要额外的成本，并且可以在处理过程中直接进行。
