连铸中间罐采用新型控流装置的模拟试验

Modeling Experiment of Continuous Casting Tundish Using New Flow Control Devices

结合本钢炼钢厂板坯中间罐的控流装置,通过实验室对比试验研究,开发了新型控流装置——湍流控制器和微细泡气幕挡墙。试验结果表明,二者大大地改善了中间罐流体流动特征参数和流动轨迹。并且还具有防止注流开浇产生喷溅和减轻注流卷吸气体的作用。

The new flow control devices, turbulence inhibitor and wall gas blowing, have been developed for the tundish of slab continuous casting in No.2 Steelmaking Plant, BENXCO by compared experiments. The results showed that, those two flow control devices can not improve the key parameters and movement track for fluid flowing in the tundish remarkably, but also, avoid the molten steel to splash and reduce molten steel from gas adsorption in the filling of tundish.
