The device scavenges evenly, completely scavenges the laminar flow water on the surface of steel strips, obviously improves the uniform widthwise performance and the uniform residual stress of steel strip products, improves and solves a problem people ignore for a long time, and contributes to the improvement of the quality of the steel strip products.
Description
Technical field
The present invention relates to a kind of scavenger for hot rolling laminar flow water, the wetting system that blows in especially a kind of hot rolling production process improves, and belongs to hot rolling production process equipment technical field.
Background technology
Detect and find that hot-strip width material at opposite sides performance and residual stress usually there are differences.Through the applicant the careful of whole hot rolling production process researched and analysed, recognized: in the hot rolling production process of band steel, need to adopt laminar flow water that it is cooled off, then will purge afterwards by the laminar flow water of blow device to belt steel surface.For a long time, for being placed in the side nozzle of hot-rolling laminar water device one side, side nozzle is fixed on active side or the transmission side plate washer blow device of laminar flow water always, and nozzle height is generally than the high 100-300mm of band steel.In order to guarantee that the belt steel surface width can all be purged to, the angle of nozzle center and horizontal plane is very little.The result, the water that dashed of belt steel surface is many nearby by nozzle, purge effective, the water that is directly dashed apart from nozzle distant place belt steel surface is few, purges weak effect, and strip width is wide more, strip speed is fast more, this difference is obvious more, and causes band steel two layers of material performance and residual stress inconsistent, influences product quality.
The utility model content
The objective of the invention is to: at the problem of traditional lateral spray type laminar flow water blow device existence, by improvement to existing equipment, propose a kind of scavenger for hot rolling laminar flow water that can guarantee even purging, thereby eliminate the performance difference of the width both sides of hot-strip, guarantee product quality.
In order to reach above purpose, scavenger for hot rolling laminar flow water of the present invention comprises laminar flow cooling frame that is positioned at band steel rollgang top and the purging feed pipe that is located at band steel rollgang one side, its improvements are: described laminar flow cooling frame is hinged, has the operating position that starts the position and be parallel to band steel rollgang; The end that described laminar flow cooling frame is positioned at band steel rollgang outbound course is equipped with the horizontal scavenging header perpendicular to outbound course; One end of described horizontal scavenging header is communicated with the purging feed pipe by flexible pipe, and the below is equipped with purge nozzle at interval.
Compared with prior art and since purge nozzle apart from belt steel surface apart from unanimity, it is identical to purge angle, therefore purge evenly, belt steel surface laminar flow water can not only can be purged totally, and experiment shows that the performance uniformity of belt steel product width and residual stress uniformity are obviously improved.Therefore, it is the problem that people were ignored for a long time that the present invention has solved with the improvement of advantages of simple, help to improve the belt steel product quality, and because device of the present invention can be with the synchronous rotary movement of laminar flow cooling frame, therefore when steel scrap and accident treatment with leaving band steel rollgang top after the laminar flow cooling frame upset, do not influence execute-in-place and handle.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of a preferred embodiment of the invention.Wherein: 1---the band steel on the band steel rollgang, 2---laminar flow cooling frame, 3---the hinge of tumbling, 4---linkage section, 5---horizontal scavenging header, 6---purge nozzle, 7---connect flexible pipe, 8---purge feed pipe, 9---magnetic valve, 10---hand-operated valve.
The specific embodiment
Embodiment one
The scavenger for hot rolling laminar flow water of present embodiment as shown in Figure 1, laminar flow cooling frame 2 is positioned at the top of band steel rollgang 1, therefore one side of this laminar flow cooling frame is hinged by the hinge 3 of tumbling, and has to start position (among Fig. 1 shown in the dotted line) and be parallel to the operating position of being with the steel rollgang.Laminar flow cooling frame 2 is equipped with horizontal scavenging header 5 perpendicular to outbound course towards end both sides of band steel rollgang 1 outbound course by the linkage section 4 of downward-sloping extension, and the one end is with the purging feed pipe 8 of steel rollgang one side to be communicated with by flexible pipe 7 with being positioned at.Laterally the below of scavenging header 5 is equipped with purge nozzle 6 at interval.Purge feed pipe 8 magnetic valve 9 and hand-operated valve 10 are housed.Laterally the purge nozzle 6 of installing on the scavenging header 5 is evenly distributed on the top of band steel 1 (roller-way), than the high 800-1200mm of band steel 1 (or roller-way top roll surface), 0-80 ° of the top rake of purge nozzle 6 (purge nozzle 6 axis and the vertical plane clockwise direction angle that passes through scavenging header 5 center lines), 0-40 ° of angle of heel (the fan-shaped purging face of purge nozzle 6 and the clockwise angle of scavenging header 5 center lines), like this, under the control of two valves, purge nozzle 6 can be carried out required purging to band steel 1 surface, it purges the angle ideal, distance is near, therefore purges respond well.Because the quality of linkage section 4, horizontal scavenging header 5, purge nozzle 6 and connection flexible pipe 7 is much smaller than laminar flow cooling frame 2, therefore to laminar flow cooling frame 2 normal stressed not influences, when tumbling, laterally scavenging header 5 can be left the top of band steel 1 (roller-way) with laminar flow cooling frame 2.Because linkage section 4, laterally scavenging header 5, purge nozzle 6 and connect the quality of flexible pipe 7 and much smaller than laminar flow cooling frame 2, laminar flow cooling frame 2 normal force-bearing situations are not influenced, equipment operate steadily, reliable and secure.
Facts have proved that device of the present invention operates steadily, safe and reliable, compared with prior art, nozzle apart from belt steel surface apart from unanimity, the purging angle is identical, and the purging effect is even, when the kind of rolling difficult purging, for example when speed is not more than 650m/m, the following specification of width 1100mm is perhaps when speed is not more than 600m/m, during the above specification of width 1100mm, belt steel surface laminar flow water purges very clean, and properties of product uniformity and residual stress uniformity are obviously improved.And laterally scavenging header is overturn simultaneously with laminar flow cooling frame, has then guaranteed when field accident is handled easy to operate.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
