Problems solved by technology

[0003] For the cutting of steel blocks, flame cutting is mainly used. Its work intensity is high, and the whole cutting process has a lot of smoke and dust, which will also affect the surrounding environment, and it is difficult to manage. When cutting, the kerf is usually wide, generally 20-40cm, The loss of metallic iron is relatively large, so this treatment method cannot meet the current scientific and environmental protection production requirements

Embodiment Construction

[0015] Referring to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention include the shape, structure, mutual position and connection relationship of each part, the function and working principle of each part, and the manufacturing process of the various components involved. And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0016] see Figure 4 It can be seen from the schematic diagram of steel processing that the molten steel in the ladle 5 is poured into the tundish 6, and the bottom of the tundish 6 is provided with an opening and connected to the continuous casting machine 7, which is pulled out to produce the product billet 2. After the tundish 6 is poured into the 2-3 furnaces of molten steel in the ladle 5, in or...

Abstract

The invention discloses a method for treating excess cast steel in a continuous casting tundish: after the steelmaking and continuous casting tundish is replaced, before the remaining molten steel in the tundish is solidified, several dividing plates are vertically inserted into the tundish at intervals In the molten steel in the tundish, after the molten steel in the tundish is cooled and solidified, the cut off steel block is taken out. This treatment method can reduce the cutting amount of residual steel in the tundish, reduce the loss of metallic iron, increase the recovery rate of metallic iron, reduce the labor intensity of workers, and at the same time avoid the smoke and dust pollution caused by cutting, improve the working area and surrounding environment, and reduce the investment in dust removal And operating costs, reduce production costs, do not need to use large vehicles for reverse transportation, and save cutting and processing sites.

Description

technical field [0001] The invention belongs to a device and a method for treating molten steel in a steelmaking continuous casting tundish. Background technique [0002] At present, in the production process of steelmaking and continuous casting, the tundish needs to be replaced after pouring several furnaces of molten steel. In order to prevent impurities from polluting the quality of steel products produced in the continuous casting machine, some molten steel is mixed in the replaced tundish. The specific method For, after the steelmaking and continuous casting tundish is replaced, it is hoisted to the maintenance area for cooling by a crane. After the residual molten steel in the tundish is solidified, it is placed on the tundish slag turning machine with a driving hoisting seat, and the slag turning machine is rotated. Turn out the lining of the tundish and the scrap steel blocks, and then clamp the scrap steel blocks to the open space next to them with tongs for cuttin...
