ABSTRACT The continuous steel casting process is characterised by physico-chemical phenomena that are considered in the macro- and microscale. This paper attempts to assess the impact of local changes in the hydrodynamics of liquid steel flow in a one-strand slab tundish on the behaviour of the alloy addition, and consequently, the chemical homogenisation of the liquid steel entering the mould. Four variants of feeding the alloy addition to the liquid steel were considered. Water glass model was used for laboratory experiments. A tracer was fed into the water using the pulse-step method. Based on the mixing curves, the mixing time was calculated. Based on the laboratory experiments carried out, it has been found that, the alloy addition feeding site affects the mixing time, both for symmetric and asymmetric feeding relative to the longitudinal axis of the tundish.

连铸板坯中间包钢液合金化过程中流体相互作用的物理模拟

摘要 连续铸钢过程的特点是在宏观和微观尺度上考虑物理化学现象。本文试图评估单股板坯中间包中钢水流动的流体动力学的局部变化对合金添加行为的影响，从而对进入模具的钢水的化学均质化产生影响。考虑了将合金添加到钢水中的四种变体。水玻璃模型用于实验室实验。使用脉冲步进法将示踪剂加入水中。根据混合曲线，计算混合时间。根据所进行的实验室实验发现，合金添加加料部位会影响混合时间，
