Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking equipment, in particular to a tundish impact cup with good impact resistance effect. Background Art

[0002] The tundish is a refractory container used in short-process steelmaking. The molten steel in the ladle is received by the tundish and then distributed to each crystallizer through the water inlet, which plays the role of transferring the molten steel and removing impurities in the molten steel as much as possible during the transfer process. In order to avoid direct contact between the molten steel and the tundish when pouring the molten steel from the ladle, an impact cup is usually added to the bottom of the tundish to cushion the impact of the molten steel on the tundish, thereby increasing the service life of the tundish.

[0003] In order to achieve better impact resistance, the existing impact cup is usually fixed at the water inlet of the tundish. However, in actual operation, since the impact cup is integrally connected to the tundish, the impact cup cannot be replaced after being worn or thermally corroded and needs to be scrapped together with the tundish, which is inconvenient to use. Therefore, we propose a tundish impact cup with good impact resistance to solve the above problem. Utility Model Content

[0020] By installing a detachable wear-resistant part 6 above the impact cup seat 1, when the surface of the wear-resistant part 6 is worn, the intercepting baffle 8 can be pulled out upwards, and the wear-resistant part 6 can be removed from the two groups of columns 4 on the impact cup seat 1, so that the wear-resistant part 6 can be quickly replaced, thereby improving the overall impact resistance of the equipment, and then the intercepting baffle 8 and the baffle 11 installed on the top of the impact cup seat 1 can be used to intercept the molten steel so that it can smoothly enter the flow stabilizing sleeve 3, and then the flow stabilizing sleeve 3 can stabilize the flow of the molten steel, and the intercepting baffle 8 can also be quickly disassembled, so that the corresponding parts of the entire equipment can be quickly replaced after damage, which can not only avoid waste of resources, but also improve the maintenance efficiency of the equipment.

[0021] The wear-resistant part 6 is integrally cast, which improves the overall strength of the wear-resistant part 6 and thus improves the impact resistance of the equipment.

[0022] In other embodiments, the tops of the two groups of columns 4 are both provided with mounting grooves 10, and the bottoms of the baffles 11 are provided with two groups of mounting rods 12, and the bottoms of the two groups of mounting rods 12 can be inserted into the mounting grooves 10 on the columns 4;
