The goal of this work is to describe in detail a quasi-stationary state model which can be used to deeply understand the distribution of the heat in a steel plate and the changes in the solid phases of the steel and into liquid phase during the flame cutting process. We use a 3D-model similar to previous works from Thiébaud (J. Mater. Process. Technol. 214(2):304–310, 2014) and expand it to consider phases changes, in particular, austenite formation and melting of material. Experimental data is used to validate the model and study its capabilities. Parameters defining the shape of the volumetric heat source and the power density are calibrated to achieve good agreement with temperature measurements. Similarities and differences with other models from literature are discussed.

固相融化钢板火焰切割的建模与仿真

这项工作的目的是详细描述准稳态模型，该模型可用于深入了解钢板中的热量分布以及火焰切割过程中钢中固相和液相的变化。处理。我们使用的3D模型类似于Thiébaud的先前工作（J. Mater。Process。Technol。214（2）：304-310，2014），并对其进行扩展以考虑相变，特别是奥氏体的形成和材料的熔化。实验数据用于验证模型并研究其功能。校准定义体积热源形状和功率密度的参数，以实现与温度测量的良好一致性。讨论了与文献中其他模型的异同。
