because technique scheme is used, the utility model compared with prior art has following advantages: the madial wall of mouth of a river main body is provided with multiple lug boss, when molten steel flows into the inner chamber of mouth of a river main body from top to bottom, lug boss adds drag to molten steel, molten steel impact is scattered out to lug boss, slow down potential energy, when flowing out via bottom side opening, flow velocity relaxes, thus is beneficial to the continuous casting work of the slab in the crystallizer of below.
Accompanying drawing explanation
fig. 1 is the utility model generalized section;
wherein: 1, mouth of a river main body; 11, upper-side hole; 12, lower-side hole; 13, lug boss; 2, slag line; 3, insulating inner lining layer.
Detailed description of the invention
as shown in drawings, a kind of submersed nozzle of large discharge current stabilization speed of continuous casting crystallizer for plate billet, comprises mouth of a river main body 1, slag line 2, and the bottom of mouth of a river main body 1 offers the side opening of molten steel outflow, and side opening is positioned at the below of slag line 2.
the madial wall on mouth of a river main body 1 top is provided with the lug boss 13 that multiple centerline direction to mouth of a river main body 1 extends, is preferably as 3-7.The madial wall of mouth of a river main body 1 and the madial wall of slag line 2 are coated with insulating inner lining layer 3, in lug boss 13 is wrapped in by insulating inner lining layer 3.Multiple lug boss 13 is arranged in the inner chamber on mouth of a river main body 1 top along the above-below direction spatial intersecting of mouth of a river main body 1, thus can lower preferably molten steel dirty time speed and intensity.
side opening comprises a pair upper-side hole 11 and pair of lower hole 12 that distribute along mouth of a river main body about 1, the setting that the center line of two holes of two holes of often pair of upper-side hole 11 and lower-side hole 12 relative mouth of a river main body 1 is respectively symmetrical, upper-side hole 11 is in equilateral triangle, lower-side hole 12 is in trapezoid, the lower length of side of upper-side hole 11 and the top appearance etc. of lower-side hole 12.Upper-side hole 11 and lower-side hole 12 are respectively inclined hole, and the angle a in inclined hole relative level face is between-25 ° to 0 °, as being-15 ° in the present embodiment.There is angle in upper-side hole 11 and lower-side hole 12, angular range is 45 ° to 90 ° in the horizontal direction.It is 90 ° that this practicality is executed in example, thus effectively ensures side opening wall intensity.
molten steel is from top to bottom to time dirty, and after being slowed down by multiple lug boss 13 choked flow, more successively by upper-side hole 11 and lower-side hole 12, the output gradual change of molten steel is gradually large, and the comparatively large but speed of flow is slowly stablized, and effectively dispersion molten steel is to the impact of crystallizer.And molten steel flows out from upper-side hole 11 and lower-side hole 12, reduce molten steel to the perturbation action of liquid level, prevent liquid level slag and meniscus place from forming crackle, avoid molten steel to the destruction of nascent solidified shell.
as mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present utility model.
