Physics-based Finite Element Methods models can be used to investigate the electrical conditions in submerged arc furnaces (SAFs). However, their explicit solution may be very demanding in terms of time and computational resources. This makes these models difficult to employ during control operations and in fast prototyping. To obviate these inconveniences, we developed metamodels that are grounded on the physics-based model. In this context, a metamodel is a surrogate of an original model obtained using statistical analysis tools to determine approximate input–output relationships in a database of simulations from the original model. The metamodels for the SAF electrical conditions are shown to retain the same generalization capabilities as the original model while being computationally lightweight.

埋弧炉中电条件的元建模

基于物理的有限元方法模型可用于研究埋弧炉(SAF)的电气状况。但是,它们的显式解决方案在时间和计算资源方面可能要求很高。这使得这些模型难以在控制操作和快速原型制作中使用。为了消除这些不便,我们开发了基于物理模型的元模型。在这种情况下,元模型是原始模型的替代,该原始模型是使用统计分析工具从原始模型的模拟数据库中确定近似的输入-输出关系而获得的。显示了SAF电气条件的元模型可以保持与原始模型相同的泛化能力,同时计算量轻。
