Abstract

The quality of the bloom will be impacted by the non-metallic impurities in the molten steel in the tundish, which will reduce the plasticity and fatigue life of the steel. In this research, a mathematical model of a six-flow double-channel T-shaped induction heating tundish was established, the effects of induction heating conditions on the removal of inclusions in the tundish were investigated, and the impact of various inclusion particle sizes on the removal effect of inclusions under induction heating was explored. The results show that the Residence Time Distribution (RTD) curve produced through numerical simulation and physical simulation is in good agreement. The reduction of inclusion particles in the channel is made affordable by the dual-channel induction heating technique. As the diameter of inclusion particles increases from 10 μm to 50 μm, the probability of inclusion particles being removed from the channel gradually decreases from 70.9% to 56.1%.

摘要

中间包内钢水中的非金属杂质会影响铸坯质量，降低钢材的塑性和疲劳寿命。本研究建立了六流双通道T型感应加热中间包的数学模型，研究了感应加热条件对中间包内夹杂物去除的影响，并探讨了不同夹杂物粒径对感应加热下夹杂物去除效果的影响。结果表明，通过数值模拟和物理模拟得到的停留时间分布（RTD）曲线吻合良好。双通道感应加热技术使得通道内夹杂物颗粒减少。随着夹杂物颗粒直径从10μm增加到50μm，夹杂物颗粒从通道中被去除的概率逐渐从70.9%降至56.1%。
