Abstract

The invention relates to the technical field of refractory materials for steelmaking and particularly relates to a tundish. The tundish comprises a tundish shell body, a tundish impact barrel and a slag blocking wall, wherein the tundish shell body is a shell structure opening at the top; the tundish impact barrel is arranged on the inner bottom wall of the tundish shell body and close to the side wall of the tundish shell body; the slag blocking wall is vertical, and the two ends and bottom thereof are embedded in the inner wall and bottom wall of the tundish shell body respectively; an impact area is formed between the slag blocking wall and the tundish shell body; the tundish impact barrel is positioned in the impact area; and multiple penetrating tundish water ports are formed in the bottom wall of the tundish shell body. The tundish provided by the invention has the advantages of simple structure, reasonable design, high integrity, good molten steel flow stabilizing effect and relatively good flow division effect and slag corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of refractory materials for steelmaking, in particular to a tundish. Background technique [0002] The tundish is a refractory container used in short-process steelmaking. It first receives the molten steel poured from the ladle, and then distributes it to each crystallizer through the tundish nozzle. The tundish is the middle link of the steelmaking production process, and it is also the transition point from intermittent operation to continuous operation. As a metallurgical reactor, the tundish is an important part of improving steel production and quality. [0003] With the increase of the tapping temperature of the converter, the application of various ladle refining technologies, and the continuous increase in the number of continuous pouring furnaces and continuous pouring time of the tundish, the pressure on the lining of the tundish continues to increase, and the working environment becomes more sev...
