摘要: 针对1 240 mm×200 mm板坯连铸提出了一种钢水内外复合冷却技术,即在“结晶器内设置内冷却器-U形管”,起到提高传热效率和改善钢液流动之目的。运用流体力学分析软件,就内外复合冷却结晶器内钢水的流动状态进行了数值模拟,发现内冷却器可以使结晶器内钢水的流动状态均匀,部分起到电磁制动之功效,有利于钢液中的夹杂物上浮。

Abstract: A technology of inner-outer couple cooling of molten steel in mold for 1 240 mm x 200 mm slab concasting i, e, to set an inner cooling apparatus- U shape pipes has been advanced to enhance efficiency of heat transfer and improve flow of molten steel. The flow status of molten steel in the inner-outer couple cooling mold was simulated by using fluid dynamics software. It is found that the flow status of molten steel in mold is uniform by using inner U- shape cooling apparatus, which has effect of electromagnetic trig to be favourable to inclusion in steel floating up.
