摘要
针对攀钢六流大方坯连铸中间包,采用等温和非等温物理模拟的研究方法,研究了钢水在中间包内的流动规律。实验结果表明自然对流对钢液的流动模式具有重要的影响,因此,对于体积大、流间距长的中间包必须采用非等温的模拟研究方法。实验还证明了在非等温情况下中间包内加控流装置的必要性。
The flow pattern of molten steel in tundish of the 6-strand bloom caster at PZH Steel were investigated by physical simulation with isothermal and non-isothermal model.The results show that the natural convection has an important effect on the fluid flow in continuous casting tundish, so a non-isothermal water model should be employed when study the fluid flow pattern in big volume tundish. The experiments show the flow control device is necessary in tundish with the non-isothermal model.
