Description
Technical field
The utility model relates to the ladle of ingot steel casting, more particularly, relates to ingot steel casting collector nozzle of ladle device.
Background technology
In ingot steel casting process, controlled switch and the adjust flux of molten steel by slide gate nozzle.Slide gate nozzle is made up of filling pipe end, upper slide, lower skateboard, the lower mouth of a river etc.Filling pipe end and upper slide are fixed on ladle bottom, and the lower mouth of a river and lower skateboard are placed in slide mechanism.When pouring into a mould, by External Force Acting, lower skateboard being slided together with the lower mouth of a river, by means of the misalignment in upper and lower slide plate aperture, controlling the size of opening and closing and adjustment steel stream, poring rate is meeted the requirements.Meanwhile, molten steel, through the rectified action at the lower mouth of a river, takes bet method injection feed trumpet or top teeming process directly to inject in ingot mould.
With the carrying out of cast, lower mouth of a river inwall produces melting loss by the violent scour of high-temperature molten steel, add the static pressure that in ladle, molten steel is huge simultaneously, can be there is swirling diffusing when going out the mouth of a river in beam, namely there is radial dispersing, the phase can be more obvious after being cast for this phenomenon, because molten steel constantly reduces in ladle, vertically constantly reduce to static pressure, mouth of a river inwall melting loss aggravation simultaneously, therefore diffusing is even more serious.The aggravation of diffusing to cast carry out smoothly and ingot quality controls to bring adverse influence, increase with beam and surrounding atmosphere contact interface can aggravate nitrogen pick-up and the secondary oxidation of molten steel, and the upper note molten steel surface of steel ingot caused of splashing scabs and crackle, beam also can be caused time serious to be partial to feed trumpet side, to cause feed trumpet bleed-out.
Particularly at the scene after ladle SN mechanism changing, when lower mouth of a river contraction in length, this diffusing situation is more obvious, because with the shortening of lower mouth of a river passage, the rectified action of beam molten steel is also weakened thereupon, therefore need to take measures to improve dispersing of beam, keep circular jet cast, what be beneficial to cast carries out the improvement with steel ingot inside and outside quality smoothly as far as possible.
Utility model content
For the phase after being cast existed in prior art because molten steel constantly reduces in ladle, vertically constantly reduce to static pressure, the problem that diffusing is even more serious, the purpose of this utility model is to provide ingot steel casting collector nozzle of ladle device.
For achieving the above object, the utility model adopts following technical scheme:
A kind of ingot steel casting collector nozzle of ladle device, it is characterized in that, ingot steel casting collector nozzle of ladle device is hollow cylinder, and two openings of cylinder are respectively upper port and lower port, the inwall circumference of cylinder equidistantly distributes many ribs, and rib penetrates into lower port from upper port always.
According to an embodiment of the present utility model, the two sides of each rib are at a right angle.
According to an embodiment of the present utility model, near the upper port of ingot steel casting collector nozzle of ladle device, the diameter of outer wall is greater than the diameter of outer wall near lower port.
According to an embodiment of the present utility model, the inwall circumference of cylinder equidistantly distributes four ribs, makes the inner wall section of cylinder be cross.
According to an embodiment of the present utility model, the inwall circumference of cylinder equidistantly distributes three ribs.
According to an embodiment of the present utility model, two right-angle side length of rib are 10-12mm.
In technique scheme, after ingot steel casting collector nozzle of ladle device of the present utility model carries out ingot steel casting, effectively can improve dispersing of cast middle and later periods steel stream, keep circular jet cast, therefore be extremely conducive to control and the operation of feed trumpet centering of noting speed, reduce that the surface of steel ingot that molten steel diffusing causes scabs, crackle and internal soundness defect.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
As depicted in figs. 1 and 2, ingot steel casting collector nozzle of ladle device 1 overall shape of the present utility model is hollow cylinder, and the hollow space of cylinder is mouth of a river passage, and its upper and lower two end faces are plane, and namely two openings are respectively upper port 3 and lower port 4.The inwall circumference of cylinder equidistantly distributes many ribs 2, and rib 2 penetrates into lower port 4 from upper port 3 always.
See figures.1.and.2, according to a kind of preferred embodiment of the present utility model, equidistantly distribute four ribs 2 along mouth of a river inwall circumference, make the inner wall section of cylinder be cross.Rib 2 penetrates into lower port 4 from upper port 3 always, and two sides of each rib 2 are at a right angle.But the quantity of above-mentioned rib 2 just with explaining, and is not a restriction of the present utility model, and in another embodiment of the present utility model, also can adopt the structure equidistantly distributing three ribs 2, effect is equal to substantially with the structure of four ribs 2.Preferably, two right-angle side length of rib 2 are 10-12mm.
Continue with reference to Fig. 1, near the upper port 3 of ingot steel casting collector nozzle of ladle device 1, the diameter of outer wall is greater than the diameter of outer wall near lower port 4.
In pouring molten steel, utilize the guide functions of rib 2, slow down beam dispersing along lower mouth of a river radial direction, rib 2 also plays and slows down mouth of a river inwall by the effect of molten steel melting loss simultaneously, keep the consistency of beam channel shape, make steel pouring stream keep circular jet form, facilitate the centering of feed trumpet during pouring practice, reduce the interface that beam contacts with surrounding atmosphere, thus reach the effect reducing nitrogen pick-up and oxidation.
After ingot steel casting collector nozzle of ladle device 1 of the present utility model is implemented, observe its actual beam control situation, visible beam controls good, does not substantially have Divergent Phenomenon.
As seen from the above technical solution, ingot steel casting of the present utility model changes original cylindrical structure of collector nozzle of ladle with lower spout device.In pouring molten steel, utilize the guide functions of rib 2, slow down beam dispersing along lower mouth of a river radial direction, rib 2 also plays and slows down mouth of a river inwall by the effect of molten steel melting loss simultaneously, keeps the consistency of beam channel shape, increase molten steel Radial Flow resistance, suppress dispersing of beam, make steel pouring stream keep circular jet form, reduce the contact interface of beam and surrounding atmosphere, thus reach the effect reducing nitrogen pick-up and oxidation, improve the controllability of pouring practice and improve the inside and outside quality of steel ingot.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
