Description

Technical Field

[0001] The utility model relates to the technical field related to tundishes, in particular to a tundish cover which is not easy to deform. Background Art

[0002] The tundish is the main equipment in the continuous casting process. It plays a connecting role. It receives molten steel from the ladle and supplies it to the continuous casting machine. In the process of receiving molten steel, the molten steel will produce a lot of splashes and smoke. The tundish cover prevents the molten steel from splashing out of the tundish and prevents the loss of smoke and heat energy of the molten steel. In the use of the existing tundish, the tundish cover will expand and deform in a very short time during use because it is baked by the molten steel with a temperature of more than 1500 degrees in the ladle. It needs to be replaced, which greatly increases the production cost.

The shortcoming of this utility model is that the intermediate ladle cover is an integrated device, which is easily deformed due to uneven heating, and needs to be replaced as a whole when damaged, and the replacement cost is relatively high.

[0024] like Figure 4As shown, the sides of the fixed frame 2 are in contact with the disassembly plate 1, and a second card groove 21 is provided on the inner side of one side of the fixed frame 2. The second card groove 21 cooperates with a card block 12 on the disassembly plate 1 at one end. A second card block 22 is installed on the inner side of the other side of the fixed frame 2.

The fixed frame 2 is provided with a plurality of evenly distributed fixing screws 23, and the fixing screws 23 correspond to the disassembly plate 1 one by one. The lower end of the fixing screw 23 penetrates the upper side of the fixed frame 2 and is threadedly connected with the disassembly plate 1.

[0025] like Figure 6 As shown, a sealing plate 4 is provided between two adjacent disassembly plates 1, a sliding block 41 is provided on the upper end surface of the sealing plate 4, a sliding groove 13 is installed on the bottom surface of the disassembly plate 1, and the sealing plate 4 is slidably connected to the disassembly plate 1 through the cooperation of the sliding block 41 and the sliding groove 13, and the two sides of the sealing plate 4 are respectively in contact with the lower side edges of the fixed frames 2 on both sides.

[0026] like Figure 5 As shown, the extrusion assembly 3 includes a mounting frame 31 and an extrusion rod 32. Several extrusion assemblies 3 are arranged between two adjacent fixed frames 2, and one extrusion assembly 3 is arranged between two adjacent disassembly plates 1. The two ends of the mounting frame 31 are respectively connected to the fixed frames 2 on both sides.
