Problems solved by technology

However, there are still a certain amount of inclusions that cannot be removed by floating, and finally enter the mold with the molten steel from the submerged nozzle of the continuous casting tundish and stay in the billet, which will have a great impact on the subsequent processing of the billet, and then affect the quality of the final product
Not only that, the inclusions that enter the submerged nozzle of the continuous casting tundish will also gather in it, affecting casting, and even causing nozzle blockage, resulting in continuous casting.

Abstract

The invention relates to a device for catching liquid steel inclusions at the outlet of a continuous casting tundish. Its technical scheme is: the large round tube (2) and the small round tube (3) are coaxially fixed on the circular base (1), and the upper ends of the large round tube (2) and the small round tube (3) are coaxially fixed with a round Shaped cover plate (9), filling material (5) is housed in the hollow cavity (4). Both the circular base (1) and the circular cover (9) are provided with a central through hole, the diameter of which is the same as the inner diameter of the small circular tube (3); the outer diameter of the large circular tube (2) is the same as that of the circular cover The outer diameters of the plates (9) are the same, the outer diameter of the circular base (1) is 1.1 to 1.3 times the outer diameter of the circular cover plate (9), the inner wall of the large round tube (2) and the outer wall of the small round tube (3) The radius difference is 1~4 times of the diameter of tundish stopper rod (12). The large round pipe (2), the small round pipe (3) and the circular cover plate (9) are respectively provided with the large round pipe diversion hole (6), the small round pipe diversion hole (7) and the cover plate diversion hole ( 8). The invention has the characteristics of simple structure, convenient replacement, low cost and good purification effect on molten steel.

Description

technical field [0001] The invention belongs to the technical field of catching devices for molten steel inclusions. In particular, it relates to a device for catching liquid steel inclusions at the outlet of a continuous casting tundish. Background technique [0002] With the development of continuous casting technology, the continuous casting tundish not only plays the role of storing and distributing molten steel, but also has the function of removing inclusions in molten steel and improving the cleanliness of molten steel. Due to the continuous improvement of the technical level of the steel industry, the requirements of the steel market for the strength, deep drawing performance, corrosion resistance and durability of steel are also continuously increasing, and the demand for clean steel is also increasing. Therefore, in the steelmaking production process, reducing inclusions in steel, eliminating external pollution in the steelmaking process and improving the cleanlin...
