摘要

摘要JSW钢铁公司，Vijayanagar工厂经营着一家44 T、用于连铸的八股方坯连铸机。这种大体积的中间包在来自围带的中心股和端股之间有很大的差异，这影响了不同股之间的清洁度和固化。为了提高中心钢绞线中的钢清洁度，在0.25级有机玻璃水模型中进行了水模型研究。研究了在稳态和非稳态条件下不同形态的大坝。楔形和V形坝的组合增加了中心股的平均停留时间，而不影响最后一股的流动行为。在中心股的停留时间增加了15%，并且不影响涡流形成高度。在工厂规模的中间包上对其进行了进一步验证。工厂试验表明，夹杂物面积百分比降低了21%，证实了中心钢绞线中的钢清洁度得到了改善。

Improvement in steel cleanliness of central strand in billet caster

ABSTRACT JSW Steel, Vijayanagar works operates a 44 T, eight-strand billet caster for continuous casting. Such large volume tundish has large differences between the central and the end strands from the shroud which affects the cleanliness and solidification between different strands. With an aim to improve the steel cleanliness in central strands, water modelling studies were carried out in a 0.25-scale perspex water model. Different configurations of dams were studied under steady and unsteady state conditions. The combination of the wedge and V-shaped dam configuration resulted in increasing the mean residence time of the central strand without affecting the flow behaviour of the last strands. Residence time at central strands increased by 15% and does not affect the vortex formation height. It was further validated on a plant scale tundish. Plant trials demonstrated a reduction in inclusion area percentage by 21% confirming the improved steel cleanliness in central strands.
