通过水力学模拟六流连铸中间包后发现，原设计的中间包在夹杂物的上浮及温度的均匀性方面还存在不足，不能很好地满足生产工艺要求。通过优化设计，提出了促进夹杂物上浮和均匀中间包内钢水温度的设计方案。本文还提出了多流连铸中间包流动特性的评判方法，为类似的水力学模拟试验提供了参考。 Through the hydraulic simulation of the six-strand continuous casting tundish, it was found that the tundish of the original design was still insufficient in the floating of inclusions and the uniformity of the temperature, and could not meet the requirements of the production process well. Through the optimization design, the design scheme of promoting the temperature of molten steel in the floating and uniform tundish of inclusions was put forward. In this paper, the method of judging the flow characteristics of multi-strand continuous casting tundish is also proposed, which provides a reference for similar hydraulics simulation tests.
