Description

Technical Field

[0001] The utility model relates to the technical field of crystallizers, in particular to automatic slag adding equipment for crystallizer protective slag. Background Art

[0002] The crystallizer is a continuous steel casting equipment that receives the molten steel injected from the intermediate tank and solidifies it into a solid shell according to the specified cross-sectional shape. It is the most critical component of the continuous casting machine. Its structure, material and performance parameters play a decisive role in the quality of the casting and the production capacity of the casting machine. The crystallizer protective slag is placed on the surface of the molten steel in the crystallizer during the continuous steel casting process to keep warm, prevent oxidation and absorb non-metallic inclusions.

[0003] The existing Chinese utility model patent with reference announcement number: CN209062098U discloses a kind of automatic slag feeder for crystallizer, including: a base module, a movable frame installed on the base module, a first driving device installed on the movable frame and used to drive the movable frame to move longitudinally, a storage tank installed on the movable frame, a distributing device installed on the movable frame and connected to the storage tank, a second driving device installed on the movable frame and used to drive the distributing device to move laterally, and a connecting rod mechanism installed between the distributing device and the second driving device and cooperated with the second driving device to drive. In the utility model, the distributing device is provided with symmetrical first and second mushroom distributing devices, the first driving device drives the distributing device to move longitudinally and the second driving device drives the distributing device to move laterally, so that the first and second mushroom distributing devices move precisely in a circular trajectory around the crystallizer water outlet, and when the protective slag is spread out along the discharge channel, a circumferential spreading area is formed, so that the protective slag can be evenly spread.

[0004] The existing automatic slag feeding equipment generally uses the gravity of the protective slag to make the protective slag fall to the surface of the cleaner. This method is inefficient. At the same time, due to the influence of the volume of the protective slag, the protective slag may be blocked inside the conveying structure, affecting the normal operation of the slag feeding equipment.
