Abstract
The utility model is a kind of from centering steel-leakage preventing submersed nozzle, belongs to continuous casting functional fire resisting material field.Should be manufactured with in distance submersed nozzle the rim of a bowl end (A) below h and l distance upper groove (B) and the low groove (C) that radius and the degree of depth are R from centering steel-leakage preventing submersed nozzle respectively, and upper groove (B) and low groove (C) are parallel to each other in the horizontal direction.During use, special-purpose assorted external device directly can be snapped in two grooves, play fixing, centering effect, prevent because submersed nozzle and tundish misalign that the tundish beam that causes is eccentric, the local scour of base shell is serious even the bleed-out problem that causes, enhance productivity, reduce production cost.
Description
Technical field
The utility model belongs to continuous casting functional fire resisting material field, relates generally to a kind of from centering steel-leakage preventing submersed nozzle.
Background technology
Bleed-out refers in continuous casting initial stage or casting process, and casting blank shell solidifies in bad order or because other External Force Actings cause base shell to rupture or the run-down phenomenon that internal steel water is flowed out.Bleed-out is one of serious accident in continuous casting production process, not only affects the normal production of conticaster, reduces operating rate, but also can destroy casting machine equipment, cause device damage.
Bleed-out form has multiple, mainly comprises opening watering bleed-out, suspension bleed-out, crackle bleed-out, slag inclusion bleed-out, cut-out bleed-out and bonding steel leakage etc.The major influence factors that bleed-out occurs has: temperature and pulling rate is inconsistent, insufficient lubrication between crystallizer and base shell, covering slag addition manner are improper, Evolutions of mould geometry and liquid level is improper, basket pouring stream is eccentric.Wherein, basket pouring stream bias can cause heat transfer uneven, causes solidified shell became uneven, and base shell weakness intensity reduces, and is difficult to bear ferrostatic pressure, thus bleed-out.Misaligning of submersed nozzle is one of the reason of basket pouring stream bias.Due to reasons such as misoperations, immersible ladle nozzle centering difficulty, causes flowing into crystallizer Nei Gangliu center deflection, thus causes the local scour of base shell serious, and then bleed-out.Therefore, need a kind of steel-leakage preventing submersed nozzle badly to solve because submersed nozzle misaligns thus the bleed-out problem caused.
Utility model content
Technical problem to be solved in the utility model is; to overcome in existing submersed nozzle casting process not easily centering, cause crystallizer flow field bad, cause liquid steel level to crust; affect the fusing of covering slag, and have a strong impact on meniscus place molten steel shell growth thus cause the difficult problem of bleed-out.By the improvement to immersion water gap bowl port part external structure, provide a kind of tundish and submersed nozzle of making from the submersed nozzle of centering, reduce the generation even avoiding bleed-out, enhance productivity, reduce production cost.
In order to solve prior art Problems existing, the utility model is achieved through the following technical solutions: at distance submersed nozzle the rim of a bowl end (A) below h(h=60 ~ 80mm) and l(l=100 ~ 120mm) distance makes two that be parallel to each other in the horizontal direction, radiuses and the degree of depth is R(R=5 ~ 10mm) annular groove, be respectively upper groove (B) and low groove (C).
Should from centering steel-leakage preventing submersed nozzle; due to the existence of upper groove (B) and low groove (C); special-purpose assorted external device directly can be snapped in two grooves; play fixing, centering effect; prevent due to submersed nozzle and tundish that to misalign the tundish beam bias, crystallizer flow field deflection, the local scour of base shell that cause serious even the bleed-out problem that causes; due to the stopping accident that bleed-out causes in minimizing casting process, enhance productivity, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the sectional side elevation of the utility model along Wide Band Oxygen Sensors direction.
Fig. 2 is the sectional side elevation of the utility model along narrow end surface direction.
Fig. 3 is groove D position, the utility model vertical section enlarged drawing.
Wherein, A, bowl mouth end, B, upper groove, C, low groove, the radius of upper groove (B) and low groove (C) is R.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
A kind of from centering steel-leakage preventing submersed nozzle, making apart from 70mm place, submersed nozzle the rim of a bowl end (A) below horizontal direction one is 7mm upper groove (B) at radius and the degree of depth, in 110mm place, distance submersed nozzle the rim of a bowl end (A) below horizontal direction, a making radius and the degree of depth are the low groove (C) of 7mm.During use, special external device is snapped in two grooves and can realize mouth of a river centering.
