Abstract
The utility model relates to the technical field of hot rolled strip steel and discloses a front plate blank purging device. The device comprises a working roller cooling water main line, a prefabricated pipe and a purging header, wherein a plurality of nozzles of which the direction is reverse to that of a pressing line are formed in the purging header; one end of the prefabricated pipe is connected with the working roller cooling water main line; and the other end of the prefabricated pipe is connected with the purging header. According to the device, an electromagnetic butterfly valve is controlled by a program, the device is started, and purging water flows through the prefabricated pipe and the purging header from the working roller cooling water main line and is sprayed out from the nozzles, so that process water carried by the surface of a middle blank is purged, a width gauge can completely acquire the actual deviation distribution after strip steel is subjected to even-pass rolling, and can control the opening of a vertical roller during odd -pass rolling; and therefore, the width deviation can be eliminated.
Description
Technical field
The utility model relates to the hot-strip technical field, particularly a kind of slab blow device.
Background technology
The side cut loss of the accurate width control can the minimizing of hot-strip band steel; Improve the lumber recovery of strip, change steeper width difference, adopt FEEDFORWARD CONTROL for some; Obtaining the rolling intact back of even passage actual deviation through the width gage that is provided with before the roughing mill distributes; And when strange passage was rolling, control edger roll opening degree was to eliminate width difference.In the actual operation of rolling, because a large amount of fresh water (FW)s are carried on the intermediate blank surface, often cause width gage can't measure intermediate blank developed width deviation, influence the strip width precision.
Summary of the invention
The utility model technical problem to be solved provides a kind of fresh water (FW) that carry on the intermediate blank surface that purges; Guarantee that width gage 100% obtains the rolling intact back of even passage actual deviation and distributes; And when strange passage is rolling; Control edger roll opening degree is with slab blow device before the width gage of eliminating width difference.
For solving the problems of the technologies described above, the utility model provides a kind of slab blow device, comprises working roll cooling water main line, prefabricated pipe, has the scavenging header some and nozzle that pressure binding direction is reverse; One end of said prefabricated pipe is connected with said working roll cooling water main line, and the other end is connected with said scavenging header.
Further, be provided with the electromagnetism butterfly valve in the said prefabricated pipe.
Further, the slab blow device also comprises the scavenging header fixed support before the described width gage, and said scavenging header is fixed on the said scavenging header fixed support, and said scavenging header fixed support is fixed on to be measured on the stand.
Further, said scavenging header fixed support comprises first fixed support, second fixed support; Said first fixed support, second fixed support are fixed on the said measurement stand; One end of said scavenging header is welded on said first fixed support, and the other end of scavenging header is fixed on second fixed support.
The slab blow device can be used for purging the fresh water (FW) that carry on the intermediate blank surface before the width gage that the utility model provides; Thereby guarantee that width gage 100% obtains the rolling intact back of even passage actual deviation and distributes; When strange passage was rolling, control edger roll opening degree was to eliminate width difference.
Description of drawings
The preceding slab blow device structural representation of width gage that Fig. 1 provides for the utility model embodiment.
The specific embodiment
Referring to Fig. 1, slab blow device before a kind of width gage that the utility model embodiment provides comprises working roll cooling water main line 5, prefabricated pipe 3, scavenging header 2, scavenging header fixed support, electromagnetism butterfly valve 4.One end of prefabricated pipe 3 is connected with working roll cooling water main line 5, and the other end is connected with scavenging header 2; Electromagnetism butterfly valve 4 is included in the prefabricated pipe 3; Scavenging header 2 is fixed on the scavenging header fixed support; Have several on the scavenging header 2 and press the reverse purge nozzle of binding direction.The scavenging header fixed support is fixed on to be measured on the stand.
The scavenging header fixed support comprises first fixed support 11, second fixed support 12.First fixed support 11, second fixed support 12 are fixed on the test desk.One end of scavenging header 2 is welded on first fixed support 11, and the other end of scavenging header 2 is fixed on second fixed support 12.
Intermediate blank idol passage is rolling to be surveyed when wide through the width gage that is provided with before the roughing mill; Programme-control electromagnetism butterfly valve 4 gets electric (electromagnetism butterfly valve 4 is used for controlling flowing of prefabricated pipe 3 liquid); The slab blow device is opened; Purge water from working roll cooling water main line 5, spray from purge nozzle via prefabricated pipe 3 and scavenging header 2, thereby purge the fresh water (FW) that carry on the intermediate blank surface.
The slab blow device has following beneficial effect before the width gage that the utility model provides:
1. guarantee that width gage 100% obtains the rolling intact back of even passage actual deviation and distributes, and when strange passage was rolling, control edger roll opening degree was to eliminate width difference.
2. simple in structure, in engineering, be convenient to realize.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
