一种连铸中间包用钢液旋流控制器

By designing a cylindrical molten steel vortex controller, the molten steel is made to rotate in a spiral by using a vortex guide cone and a parabolic inner wall. This solves the problems of high flow velocity and difficulty in controlling the flow direction in turbulence controllers, and achieves the stability of the flow field in the tundish and the improvement of the quality of the continuously cast billet.

AI Technical Summary

Technical Problem

Existing turbulence controllers still have a relatively high flow velocity and the flow direction is difficult to control when molten steel flows into the tundish, resulting in an unstable flow field in the tundish and affecting the quality of continuously cast billets.

Method used

A cylindrical molten steel vortex controller is designed, with a hollow cavity inside. The top center is used for injection, the edge is used for outflow, and the bottom center is equipped with a vortex guide cone. Combined with the parabolic inner wall, the controller is built into the bottom of the tundish. Under the action of the vortex guide cone, the molten steel spirals along the parabolic inner wall and flows out in a spiral upward direction, reducing turbulence and extending the flow process and residence time.

Benefits of technology

It significantly reduces the impact of molten steel on the liquid surface, extends the process and residence time, improves the uniformity of the flow field temperature and the floating rate of inclusions in the tundish, and improves the quality of continuously cast billets.
