Embodiment 1
[0030] When pouring the slab, you can use such as Image 6 The shown two-sided four-hole submerged nozzle is used for pouring, and the cross-sections of the submerged water side wall 1 and the inner cavity 3 are both flat with front and rear planes and left and right arc surfaces. The bottom 2 of the submerged nozzle is set in a concave shape, the inclination angle of the upper and lower walls of the first side hole 4 and the second side hole 5 is -15°, the inclination angle of the outer wall surface is 20°, and the side holes are chamfered square, The chamfer radius is 10mm. The width of the spacer 6 between the holes on both sides is 15mm. During pouring, the spacer 6 is aligned with the center of the narrow surface of the slab crystallizer 7, and the molten steel enters from the upper opening of the inner cavity 3 and flows out from the first side hole 4 and the second side hole 5, which can reduce the temperature of the high temperature molten steel. The impact on the ce...
Embodiment 2
[0032] When pouring blooms, such as Figure 7The shown two-sided four-hole submerged nozzle is poured, and the cross-section of the submerged water side wall 1 and the inner cavity 3 is circular. The bottom 2 of the submerged nozzle is set in a concave shape, the inclination angle of the upper and lower walls of the first side hole 4 and the second side hole 5 is -10°, the inclination angle of the outer wall surface is 30°, and the side holes are chamfered square, The chamfer radius is 10mm. The width of the spacer 6 between the holes on both sides is 15 mm. When pouring, the spacer 6 is aligned with the center of the narrow surface of the bloom mold 8, and the molten steel enters from the upper opening of the inner cavity 3 and flows out from the first side hole 4 and the second side hole 5, which can reduce the temperature of the high temperature molten steel. The impact on the thinner billet shell in the center of the narrow face, and the temperature compensation for the ...
