Embodiment 1
[0037] Such as figure 1 with image 3 As shown, a continuous casting tundish for improving the cleanliness of molten steel includes a slag retaining wall 1, an overflow groove 2, a ladle nozzle 3, a tundish main body 4, a tundish outlet 5, a dam 6, and a ventilating brick 9 composition.
[0038] The lower nozzle 5 of the tundish is installed on one side of the bottom of the main body 4 of the tundish; The sliding nozzle at the bottom of the ladle above the area 10, the lower end is immersed in 8mm-15mm below the molten steel surface of the tundish); the dam 6 is installed at the bottom of the main body 4 of the tundish. The slag retaining wall 1 is installed between the ladle shroud 3 and the dam 6 , and the slag retaining wall 1 divides the tundish 4 into two parts, the pouring impact area 10 and the pouring area 11 . The slag retaining wall 1 is trapezoidal with a large upper part and a smaller lower part, both sides are connected with the two side walls of the tundish main...
Embodiment 2
[0042] Such as figure 2 with Figure 4 As shown, a continuous casting tundish for improving the cleanliness of molten steel includes a slag retaining wall 1, an overflow groove 2, a ladle nozzle 3, a tundish main body 4, a tundish outlet 5, a dam 6, and a ventilating brick 9 composition.
[0043] Two tundish nozzles 5 are installed on both sides of the bottom of the tundish main body 4; the large ladle shroud 3 is installed on the sliding nozzle at the top ladle bottom of the tundish main body 4 (the upper end of the large ladle shroud 3 is installed in the middle On the sliding nozzle at the bottom of the ladle above the impact area 10 of the injection flow, the lower end is immersed in 8mm-15mm below the molten steel surface of the tundish); two dams 6 are installed at the bottom of the main body 4 of the tundish. Two slag retaining walls 1 are installed between the ladle long nozzle 3 and the dam 6, and the slag retaining wall 1 divides the tundish 4 into an injection im...
