Single-layer tundish covering agent for continuous casting of high-aluminum titanium steel

The invention relates to a single-layer tundish covering agent for continuous casting of high-aluminum titanium steel, and relates to the field of continuous casting of ferrous metallurgy, and the covering agent comprises the following components in percentage by mass: 30-40% of CaO, 30-38% of Al2O3, 7.5-16.0% of SiO2, 7.0-12.5% of MgO, less than or equal to 1.0% of TC, less than or equal to 3.0% of Fe2O3, 2.50-7.50% of Na2O and less than or equal to 0.05% of H2O. The bulk density is 0.55-0.95 g/cm < 3 >, the particle size (0.5-5.0 mm) is greater than or equal to 85%, and the melting point is 1350 +/-100 The scheme is mainly used for the continuous casting process of the high-aluminum titanium steel, the crusting phenomenon of a tundish covering agent in the casting process is prevented, the number of continuous casting furnaces in the casting process is increased, meanwhile, the Als burning loss, the Ti burning loss and the [Si] increasing process in the molten steel are reduced, and the cleanliness of the m
