Example Embodiment
[0025] Example 1
[0026] Combine figure 1 with figure 2 In this embodiment, a nozzle flow control device for preventing swirling flow in a continuous casting tundish includes a sleeve 2, a discharge pipe 3, an inlet plate 4, a flow guide hole 5, a flow control plug 6 and a lifting mechanism, The drain pipe 3 penetrates the tundish bottom 1 and extends into the inside of the tundish. The drain pipe 3 is hollow. In this embodiment, the drain pipe 3 is provided with a sleeve 2 where the drain pipe 3 contacts the tundish bottom 1. The sleeve 2 is sleeved on the outside of the drain pipe 3, and an annular gap is provided between the sleeve 2 and the drain pipe 3. The annular gap is connected with the inert gas input device, and the inert gas is blown through the bottom The gas method can effectively prevent molten steel from inhaling gas. A liquid inlet pan 4 is fixedly connected to one end of the discharge pipe 3 that extends into the tundish. The top and sides of the liquid in...
