Abstract
The invention relates to a highline outlet reverse air blowing device. The highline outlet reverse air blowing device is characterized in that the reverse air blowing device is formed through improvement on a guide groove of a highline 30# rolling mill outlet, the guide groove consists of a first outlet upper guide plate, a second outlet upper guide plate and an outlet lower guide plate, a stepped round hole is machined in the first outlet upper guide plate, penetrates through the guide groove position to extend to the outside, and compressed air is led to the round hole through a common oil gas connector. Compared with the prior art, the highline outlet reverse air blowing device has the advantages that the highline outlet reverse air blowing device is ingenious in structural design, good in practicability and convenient to assemble and replace in a site; the guide groove provided in the technical scheme is a combined guide groove and consists of the first outlet upper guide plate, the second outlet upper guide plate and the outlet lower guide plate. The round hole is formed in the first outlet upper guide plate, and connection is achieved by means of the compressed air in the site and a connecting valve, and finally a reverse air blowing role is played on water in the guide groove, so that the water for sizing decrease can b e prevented from being carried way from the guide groove.
Description
Technical field
The present invention relates to a kind of blowback air device, particularly a kind of high line outlet blowback air device, belongs to steel rolling equipment technical field.
Background technology
Subtracting sizing is the essential equipment of high-speed rod-rolling mill, and sizing not only can make the dimensional accuracy of rolled piece higher in present subtracting, out-of-roundness is less, and the more important thing is that lifting has very great help to speed.This is also the main cause that the speed of high-speed rod-rolling mill rolling small dimension can exceed 100m/s.But high-speed rolling also can bring many problems.The heap steel that subtracts sizing region happens occasionally, trace it to its cause, a lot of all due to small dimension medium and high carbon steel rolled piece operation of rolling high speed with subtract the generation of colliding of sizing collars, guide groove, the water-cooled of water tank increases medium and high carbon steel fragility in addition, is finally easy to cause workpiece front end to produce broken head and causes heap steel.Current for avoiding this situation, substantially sacrifice finish to gauge speed avoiding piling the generation of steel accident, and this has just affected the raising of production efficiency greatly, has run counter to the original intention that production manager imports advanced equipment.Therefore, a kind of new technical scheme of exigence solves the problems of the technologies described above.
Summary of the invention
The present invention is just for the technical problem existing in prior art, a kind of high line outlet blowback air device is provided, this technical scheme forms the guide groove of pressure-air blowback air, thereby prevents that broken head from appearring in rolled piece, and prevents that cooling water from being taken out of and subtract sizing and cause rolled piece to occur unnecessary secondary water-cooled.
To achieve these goals, the technical solution used in the present invention is as follows, a kind of high line outlet blowback air device, it is characterized in that, described blowback air device is improved by high line 30# milling train spout guide, this guide groove is by the first outlet upper guide plate, the second outlet upper guide plate and outlet bottom guide composition, outlet bottom guide plays base simultaneously, upper guide plate and bottom guide are fixed by iron wire, on described the first outlet upper guide plate, be provided with a circular hole, this circular hole is positioned at the first delivery guide end, Circularhole diameter is Φ 4mm, inside stretching stepped hole diameter is Φ 6mm, this circular hole angle and guide groove are 58-62 °, be 90 ° with inclined-plane, circular hole length one is through to guide groove place.
As a modification of the present invention, described Circularhole diameter is Φ 5mm, and inside stretching stepped hole diameter is Φ 7mm, in this step circular hole, extends guide groove, and its axis direction and horizontal direction are 60 °, and its axis direction is perpendicular to the inclined-plane of the first outlet upper guide plate end.
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) guide groove that the technical program provides is a knockdown guide groove, is made up of the first outlet upper guide plate, the second outlet upper guide plate and outlet bottom guide.By the circular hole of the first outlet upper guide plate, and utilize on-the-spot compressed air to connect by connection valve, finally the water in guide groove is played to the effect that a blowback is swept, make the water that subtracts sizing avoid taking out of from guide groove.

Detailed description of the invention
In order to deepen the understanding of the present invention and understanding, below in conjunction with the drawings and specific embodiments, the invention will be further described and introduction.
embodiment 1: referring to Fig. 1, a kind of high line outlet blowback air device, described blowback air device is improved by high line 30# milling train spout guide, this guide groove is by the first outlet upper guide plate, the second outlet upper guide plate and outlet bottom guide composition, outlet bottom guide plays base simultaneously, upper guide plate and bottom guide are fixed by iron wire, on described the first outlet upper guide plate, be provided with a step circular hole 1, this step circular hole is positioned at the first delivery guide end, Circularhole diameter is Φ 4mm, inside stretching stepped hole diameter is Φ 6mm, be 90 ° with inclined-plane, circular hole length one is through to guide groove place, and be 58-62 ° with the direction of workpiece motion s, the circular hole that exports in addition upper guide plate connects compressed air by joint outward, compressed-air actuated airflow direction and workpiece motion s opposite direction, powerful air pressure makes cooling water can not taken out of and subtract sizing by the rolled piece of high-speed cruising.
embodiment 2: as a modification of the present invention, described Circularhole diameter is Φ 5mm, and inside stretching stepped hole diameter is Φ 7mm, in this step circular hole, extends guide groove, and its axis direction and horizontal direction are 60 °, and its axis direction is perpendicular to the inclined-plane of the first outlet upper guide plate end.All the other structures are identical with embodiment 1 with advantage.
