Embodiment 1
[0026] combine figure 1 and figure 2 , a nozzle flow control device for preventing swirling flow in a continuous casting tundish according to this embodiment, comprising a casing 2, a liquid discharge pipe 3, a liquid inlet plate 4, a flow guide hole 5, a flow control plug rod 6 and a lifting mechanism, The drain pipe 3 extends into the tundish through the bottom 1 of the tundish, and the drain pipe 3 is hollow inside. In this embodiment, a sleeve 2 is provided at the contact between the drain pipe 3 and the bottom 1 of the tundish. The casing 2 is sleeved on the outside of the discharge pipe 3, and there is an annular gap between the casing 2 and the discharge pipe 3. The above-mentioned 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 the molten steel from absorbing gas. One end of the liquid discharge pipe 3 protruding into the tundish is fixedly connected with a liquid inlet ...
