根据连铸大方坯的凝固传热特点,应用二维非稳态传热有限元数学模型,分析在拉速波动过程中铸坯凝固时的温度分布情况,为避免在生产中由于拉速波动而产生缺陷提供了一定的理论依据。
According to the solidification heat transfer characteristics of continuous casting bloom, the two-dimensional finite element model of unsteady heat transfer is used to analyze the temperature distribution during slab solidification in the process of pulling speed fluctuation. In order to avoid the fluctuation of pulling speed in production, Produce defects provide a theoretical basis.
