[0001] The utility model relates to the technical field of continuous casting of steel, in particular to a slag adding device with an adjustable slag adding hole. Background Technique
[0002] The molten steel is cooled by a mold to form a primary shell, and the shell is separated by the reciprocating movement of the mold up and down. During this process, it is necessary to continuously add protective slag to the surface of the molten steel in the mold. The added protective slag can play a role in heat preservation, isolating air, preventing secondary oxidation of the molten steel and absorbing inclusions, and can also control the lubrication and heat transfer between the shell and the mold, so as to ensure the smooth progress of the continuous casting process.
[0003] The publication number CN209139785U discloses a slag adding device. By setting a pneumatic valve on the conveying pipeline, automatic slag adding operation can be realized, improving efficiency and saving manpower; by extending the middle part of the conveying pipeline above the molten steel in the tundish, the molten steel in the tundish can use the radiant heat of the molten steel to heat the protective slag in the conveying pipeline, so as to increase the self-temperature of the protective slag before adding it to the surface of the molten steel in the mold, effectively reducing the heat of the molten steel required for the protective slag to melt on the surface of the molten steel, enabling the protective slag to achieve a normal melting process even when the temperature of the molten steel in the mold is relatively low, greatly improving the melting ability of the protective slag, quickly forming a sufficient liquid slag layer, ensuring the surface quality of the cast billet, and ensuring the normal production of the continuous casting process. However, the following problems still exist in the actual use of this patent:
[0004] Although this slag adding device can realize automatic slag adding operation by setting a pneumatic valve on the conveying pipeline, improving efficiency and saving manpower, it cannot ensure that the protective slag can be evenly added into the mold, resulting in some protective slag not playing its role and reducing the practicability of the device.
[0005] A slag adding device with an adjustable slag adding hole is proposed to solve the problems mentioned above. Content of the Utility Model

The end of the first roller shaft 104 away from the driving motor 103 penetrates through the mixing hopper 101 and is fixedly connected to a driving wheel 105. One side of the driving wheel 105 is meshed with a driven wheel 106. The central position inside the driven wheel 106 is fixedly connected to a second roller shaft 107. One end of the second roller shaft 107 is rotatably connected to the mixing hopper 101, and the external structure of the second roller shaft 107 is the same as that of the first roller shaft 104.
