The utility model relates to a porous submerged nozzle for continuous casting in the field of refractory materials, comprising a nozzle body (1), an inner hole (2), an anti-blocking inner lining (3), a heat-retaining refractory fiber (4), and a nozzle slag line (5), a plurality of evenly distributed side holes (6), a buffer zone (7). It is characterized in that the inner hole (2) becomes larger from top to bottom, the inner side of the side hole (6) is tangent to the inner hole, and the cross-sectional area gradually increases from the inside to the outside. It can effectively adjust the flow rate and direction of the molten steel at the outlet of the side hole, form a swirling flow in the mold, change the flow state of the molten steel, and eliminate the phenomenon of turning the molten steel surface at the corner of the mold.
Description
Technical field
The present invention relates to the metallurgical continuous casting process equipment, be specifically related to the porous type submersed nozzle that a kind of large square bland continuous-casting machine is used.
Background technology
When molten steel flows into crystallizer from tundish, be the oxidation that all can not eliminate molten steel of the common stopper formula mouth of a river or the slidingtype mouth of a river, splash and the reason such as scatter and disappear of heat to the influence of slab quality, begin to be extensive use of submersed nozzle in recent years.And actual production and analog study find that all the quality of the growth of the flowing of the shape of immersion water gap for continuously casting and molten steel in mold, casting blank shell and final products is closely related, and mouth of a river shape, mouth of a river insertion depth etc. flow to the molten steel in the continuous cast mold and floating foreign is removed material impact is arranged.Therefore, in order to improve slab quality, remove field trash in the molten steel effectively, eliminate crystallizer bight molten steel face turnup phenomenon, the applicant has designed the more shallow porous type submersed nozzle of the impact depth to the beam molten steel that a kind of casting mold for continuous casting is used.
Summary of the invention
The purpose of this utility model is to provide a kind of large square bland continuous-casting machine when producing high-level steel grade, can remove field trash in the molten steel effectively, eliminates crystallizer bight molten steel face turnup phenomenon, guarantees to produce the porous type submersed nozzle that carries out smoothly.
The technical solution of the utility model is achieved in that
A kind of continuous casting porous type submersed nozzle comprises mouth of a river body 1, constantly becomes big endoporus 2, anti-blocking liner 3, thermal insulation fire-resistant fiber 4, mouth of a river slag line 5, equally distributed a plurality of side openings 6, buffering area 7 from top to bottom.It is characterized in that: inboard one side of side opening 6 is tangent with endoporus, and cross-sectional area becomes big from inside to outside gradually.
Preferably, the number of mouth of a river inboard aperture is 4;
Preferably, buffering area is arranged at internal diameter bottom, the mouth of a river, changes the flowing velocity of molten steel;
Preferably, the side opening profile is rectangle.
Preferably, side opening is axially downward-sloping, and is best, and the angle that constitutes between side opening axis and the horizontal plane is 25 °.
Adopt the mouth of a river after the utility model improves, by becoming big gradually to mouth of a river endoporus is top-down, the fine setting of side opening discharge area, and the groove buffering area of mouth of a river endoporus bottom setting, can adjust flow velocity and the direction of side opening outlet molten steel effectively, in crystallizer, form eddy flow, change the flow regime of molten steel, eliminate crystallizer bight molten steel face turnup phenomenon.The utility model is simple in structure, is easy to produce, and actual practical function is better.
Description of drawings

Fig. 2 is side opening (6) cutaway view
The specific embodiment
Below in conjunction with accompanying drawing and example the utility model is further described.
Bloom as shown in the figure and rectangular billet caster porous type submersed nozzle, it comprises mouth of a river body (1), constantly becomes big endoporus (2), anti-blocking liner (3), insulation fibre (4), mouth of a river slag line (5), equally distributed quadrisection to the buffering area (7) of side opening (6), bottom, the mouth of a river from top to bottom, adopt magnesium carbon body, zirconium carbon slag line.
During use, molten steel passes through endoporus (2) by the mouth of a river under the tundish, it is big that the cross-sectional area of endoporus (2) constantly becomes from top to bottom, and at buffering area of the bottom of endoporus (2) existence, then flow out by the big speed of four side openings (6), because the angle that constitutes between side opening axis and the horizontal plane, the jet molten steel directly rushes at the crystallizer wall, and be divided into two stream thighs up and down, form two recirculating zones up and down.Last recirculating zone has been enlivened the top molten steel and has been flowed, and is conducive to the removal of field trash, and the while also provides heat for the fusing of covering slag.Because 4 side opening opening designs make molten steel form level rotary flow after flowing into crystallizer, alleviate molten steel to the impact of crystallizer wall, protected the green compact shell effectively, and it are moving to have reduced the molten steel ground roll, avoided the generation of volume slag effectively.This continuous casting adopts magnesium carbon body with the porous type submersed nozzle, zirconium carbon slag line, and the generation of having avoided aluminium to be mingled with, and longer than the aluminium carbon submersed nozzle life-span.
It should be noted that, although the present invention is described and illustrates with reference to the specific embodiment, but and do not mean that the present invention is limited to the embodiment of these descriptions, those skilled in the art can therefrom derive many different variants, and they all will be covered in the true spirit and scope of claim of the present invention.
