摘　　要：为改善连铸板坯质量,通过水力学模拟研究了中间包内钢液的流动,并测量了在非稳定浇注条件下避免钢液卷渣的中间包内钢液的临界高度,确定了在中间包内设置抑湍器、坝和堰的混合控流方案。结果表明:中间包设置控流装置后,平均停留时间增加,有利于夹杂物的上浮;同时确定了中间包卷渣的临界高度。In order to improve the quality of continuous casting steel slab, the flow rule of liquid steel in tundish has been studied by hydraulics simulation test. Liquid steel critical highness of preventing from slag entrapment in tundish is measured at the condition of non-steady casting. The controlling scheme of installing weir, dam and turbulence inhibitor^was defined in tundish. The test results showed that with installed designed flow control devices in tundish, the average residence time was prolonged to improve the ability of removing the inclusion from liquid steeel in tundish. The critical highness of slag entrapment was gained in tundish.
