Background
In the process of continuous casting of steel, in order to prevent the phenomenon of splashing or breaking down the bottom of a tundish when molten steel enters the tundish and ensure the smooth casting and continuous casting capacity, a mode of additionally arranging a flow stabilizer is generally adopted in an impact area of the tundish. The tundish current stabilizer stabilizes the molten steel flowing state when the molten steel is injected into the impact area, so that impurities in the molten steel are filtered, and the molten steel is purified. After casting, the molten steel is cast in the flow stabilizer, and then overflows from the flow stabilizer to the casting area, so that the impact force generated in the casting process of the molten steel is effectively relieved.
However, in the conventional tundish current stabilizer, the flow rate of molten steel is too high when the molten steel enters the tundish current stabilizer, so that steel slag is easily drawn into the molten steel, and the magnesium-carbon material has weak molten steel impact resistance, steel slag resistance and erosion resistance, so that the service life of the current stabilizer is short, and the production requirement cannot be met.
