Torpedo ladle slag line zone repair material
The invention relates to the technical field of metallurgy, in particular to a torpedo ladle slag line zone repair material. The repair material comprises the following components in percentage by mass: 40 to 80 percent of aluminum silicon carbide carbon brick waste, 10 to 40 percent of third-grade brown aluminum oxide, 1 to 6 percent of calcium aluminate cement, 2 to 8 percent of clay, 1 to 8 percent of silicon carbide material, 0.01 to 0.04 percent of polypropylene fiber and balance of inevitable impurity. The torpedo ladle slag line zone repair material provided by the embodiment of the invention has the advantages that the calcium aluminate cement can improve the normal temperature physical strength of the repair material; the clay can improve the viscosity of the repair material and the construction is facilitated; the silicon carbide can further improve the slag corrosion resistance of the repair material, the repair material is enabled to not stick slag and the times of use are improved; the polypropylene fiber can reduce the drying time of the repair material after construction, improve the volumetric stability during baking or use and prevent burst. The torpedo ladle slag line zone provided by the embodiment of the invention improves the slag corrosion resistance of the torpedo ladle slag line zone repair material; since a great amount of aluminum silicon carbide carbon brick waste is adopted, the use cost of the repair material is reduced.
