Embodiment Construction
[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0020] Such as figure 1 A new type of continuous casting tundish cover is shown, including a middle cover 2 covering the mouth of the tundish and side covers 3 located on the left and right sides of the middle cover 2, and the centerline of the length direction of the middle cover 2 coincides with the central axis of the tundish ; The middle cover 2 and the two side covers 3 are also provided with a stopper hole 5 and a baking hole 6, and the peripheries of the stopper hole 5 and the baking hole 6 are fixed with arc ribs, and the middle cover 2 and the side cover 3 They are integrally cast from refractory steel respectively, and the upper and lower sides of the middle cover 2 and the side cover 3 are fixed with reinforcing ribs 4 arranged in a square shape. The middle cover 2 is left-right symmetrical about the center line of i...

The invention discloses a novel continuous casting tundish cover and an application method. The novel continuous casting tundish cover comprises a middle cover and side covers located at the left side and the right side of the middle cover. Stopper rod holes and baking holes are also formed in the middle cover and the two side covers; the middle cover and the side covers are respectively made of refractory steel in a monoblock casting way; reinforcing ribs are respectively arranged on the upper faces and the lower faces of the middle cover and the side covers; the middle cover is bilaterally symmetrical about a central axis of a tundish, and the two side covers are also bilaterally symmetrical about the central axis of the tundish; the upper face and the lower face of the middle cover are of a symmetrical structure mutually; and the upper faces and the lower faces of the side covers are of symmetrical structures mutually. According to the novel continuous casting tundish cover provided by the invention, the service life is prolonged, and the pollution on molten steel and the adverse impact on stopper rod control due to the falling off of refractory materials are completely avoided.
Description
technical field [0001] The invention relates to the field of steelmaking and continuous casting machine tundishes, in particular to a novel continuous casting tundish cover and a use method. Background technique [0002] The tundish is the key equipment in the continuous casting production process. It is an intermediate storage container between the ladle and the crystallizer. Hang around pouring the foundation. The tundish is generally composed of a body, a cover and other auxiliary facilities. The tundish cover covers the upper opening of the tundish, which is used to isolate the heat exchange between the molten steel in the tundish and the outside world, and plays the role of heat preservation and ensuring the cleanliness of the molten steel. , At the same time, it also plays the role of protecting devices such as stopper mechanism and improving the working environment on site. [0003] At present, the tundish covers used by most domestic steel mills use steel structure...
