Abstract

The invention discloses a tundish flow stabilizer. The tundish flow stabilizer is formed by integrally embedding and a hollow inner cavity into a shell, wherein the shape and the size of the shell aredesigned to be matched with an impact zone of a tundish, the center of the shell is sunken, so that the shell is shaped like a Chinese character "ao", the shell is formed by a steel fiber aluminum-magnesium castable prefabricated part, and the steel fiber aluminum-magnesium castable prefabricated part is integrally cast and formed; and the hollow inner cavity is cylindrical and is suitable for being embedded into the center of the shell, the hollow inner cavity is flush with the top of the shell, and the hollow inner cavity is formed by building magnesium carbon prefabricated parts, wherein the carbon prefabricated part is formed through isostatic pressing integral pressing. The invention further discloses a method for manufacturing the tundish flow stabilizer. According to the method, atraditional multiple-magnesium-carbon-brick building forming method of the inner cavity of the flow stabilizer is modified into an integral pressing forming method, so that inner cavity brick joints which are prone to be corroded in a traditional flow stabilizer are eliminated, then the problems of steel permeation and steel penetration of the brick joints of the inner cavity of the traditional flow stabilizer are thoroughly solved, and the service life of the tundish flow stabilizer is greatly prolonged.

Description

technical field

[0001] The invention relates to the technical field of iron and steel metallurgical continuous casting technology, in particular to a tundish flow stabilizer and a method for manufacturing the tundish flow stabilizer. Background technique

[0002] In the iron and steel metallurgical continuous casting process, the molten steel in the ladle needs to enter the tundish. In order to prevent splashing or breakdown of the bottom of the tundish when molten steel enters the tundish, and ensure smooth pouring and continuous pouring capability, a flow stabilizer is generally installed in the impact area of ​​the tundish. After pouring, the molten steel is cast in the stabilizer first, and then overflows from the stabilizer into the casting area, thereby effectively alleviating the impact of the molten steel during the casting process.

[0003] At present, the tundish current stabilizer used in the prior art is often built by masonry magnesia-carbon bricks on the inner...
