Description
Technical field
The present invention relates to a kind of horn mouth, particularly a kind of improved air-through-tube horn mouth, belongs to Rolling-mill Auxiliary Facilities technical field.
Background technology
Article one, the most important parts of rolling line are milling train and guide groove, but along with the technological improvement of equipment is upgraded, equipment can meet the rolling of more specifications, and for large specifications more than 12 specifications, finishing mill is out of use substantially, general empty mistake, want the air-through-tube of matching equipment, opening most and making the air-through-tube of introducing is exactly a common hollow steel tube, there is cone mouth at the position of rolled piece inlet, but cone mouth is too little, through scene, this air-through-tube of discovery on probation can not meet rolling demand, old-fashioned length before present rolling line ratio on the one hand, it is long to the distance between finishing mill that rolled piece goes out pre-finish rolling, another aspect mill speed is also than comparatively fast, will cause rolled piece in guide groove, to occur shake, enter again the air-through-tube of finishing mill.Cone mouth is too small likely can be caused rolled piece not enter smoothly and cause piling steel overflow.Therefore, a kind of new technical scheme of exigence solves the problems of the technologies described above.
Summary of the invention
The present invention, just for the technical problem existing in prior art, provides a kind of improved air-through-tube horn mouth, and this device can make rolled piece enter smoothly, improves operating efficiency, reduces labor strength, thus the production efficiency of providing.
To achieve these goals, the technical solution used in the present invention is as follows, a kind of improved air-through-tube horn mouth, it is characterized in that, described horn mouth comprises horn mouth body, described horn mouth body is set to cylindric, and wherein one end of horn mouth body is provided with tapering, and the horn mouth that is provided with one end of tapering connects the second cylinder.
As a modification of the present invention, described tapering is 18-22 °, and tapering is crossed conference and make the thickness attenuation of opening part, air-through-tube
Opening wearability reduce; Tapering is too small is unfavorable for that milling train enters smoothly sky and reaches a standard, and easily causes piling steel.
As a modification of the present invention, the length of described the second cylinder is 80-85mm, and the length that embeds cylindric horn mouth body is 20-25mm.Doing so on the one hand not to make whole air-through-tube oversize, distance between finishing mill is certain, there will not be the incongruent problem of size, on the other hand, the length of embedding can make the first cylinder firmly be connected with the second cylinder and can increase the opening after the second cylinder extends as far as possible.
As a modification of the present invention, the thickest position of described the second cylinder is 30-35mm, and the thinnest position is 15-18mm.
As a modification of the present invention, the diameter of described the second cylinder is Φ 120-125mm.
As a modification of the present invention, in described the second cylinder, be provided with tapering, tapering and the intrinsic tapering of horn mouth in described the second cylinder are in the same size.
As a modification of the present invention, the length of described the second cylinder is 83mm, and the length that embeds cylindric horn mouth body is 23mm.
As a modification of the present invention, the diameter of described the second cylinder is Φ 123mm.
With respect to prior art, the advantage of this technology is as follows: 1) overall construction design of the present invention is ingenious, and practical, Assembling and replacing are convenient; 2) this technical scheme is by increasing by the second cylinder, bandaging piece can be passed through smoothly, the diameter of this second cylinder is greater than the diameter of horn mouth body, but its inner tapering is consistent with bell-mouthed tapering, so just can keep round and smooth transition, large diameter can make the cone mouth that extends out larger in addition, thereby can make rolled piece more easily enter sky is out-of-date; 3) this patent is applicable to the air-through-tube of high-speed rod, and in the time of rolling large-size product, it is empty out-of-date that some passage of high velocity needs, and utilizes this empty conduit of crossing, and can effectively avoid rolled piece shake, makes rolled piece trouble-free operation, avoids overflow; 4) this technical scheme cost is lower, is convenient to promote the use of on a large scale at Steel-rolling Industry.
