Accompanying drawing explanation
The structural representation of the Surfaces of Hot Rolled Strip blow device that Fig. 1 provides for the utility model embodiment;
Wherein, 1-scavenging header, 2-nozzle, 3-source of the gas tube connector, 4-external air source, 5-support, 6-gas buffer tank.
The specific embodiment
Referring to Fig. 1, a kind of Surfaces of Hot Rolled Strip blow device that the utility model embodiment provides, for cleaning the iron scale of Surfaces of Hot Rolled Strip, the tracking of auxiliary heat metal detector is surveyed.Comprise: scavenging header 1, nozzle 2, source of the gas tube connector 3 and support 5.Scavenging header 1 is fastened on support 5, nozzle 2 and fastening being connected of scavenging header 1 end, and scavenging header 1 is connected with external air source 4 by source of the gas tube connector 3; According to place environment, suitably adjust scavenging header 1, with air-flow and the Surfaces of Hot Rolled Strip that guarantees to export by nozzle 2, form suitable angle, thereby contribute to the cleaning of iron scale.Nozzle 2 is suspended in band steel upper surface top, is arranged on cold/hot metal detector front end, thereby guarantees that hot-strip, before entering the investigative range of metal detector, completes the cleaning of iron scale.
In view of the iron scale of Surfaces of Hot Rolled Strip and the adhesion with steel entity successively increase, the adhesion of the superiors is minimum, relatively easily purges cleaning, and the current rate needing is relatively little, and more down demand intensity is larger; In practice, find, the temperature of the iron sheet being oxidized is still very high, adopts high-intensity air-flow, will cause high temperature iron sheet splashing, forms potential safety hazard and easily occurs security incident; Air pressure is too little, and bottom iron sheet is difficult to again cleaning; Preferably, adopt the air-flow of air pressure range 6.5bar～7bar to continue to purge, can avoid iron sheet excessively to splash, the iron scale of the most accumulation of assurance simultaneously can purge and clean out.
Originally be that the scavenging header that embodiment provides comprises at least three appendixs, in order to guarantee to stablize the purging air-flow of constant voltage; Preferably, this device also comprises: gas buffer tank 6; The air-flow of external air source 4 inputs, is introduced into gas buffer tank 6, after equilibrium air pressure, by scavenging header 1 and nozzle 2, is acting on Surfaces of Hot Rolled Strip, thereby guarantees to stablize the purging air-flow of constant voltage.
Purge air-flow and act on Surfaces of Hot Rolled Strip, it blows angular range is efficiently 50o～70o; Preferably, the angle that blows of the present embodiment proposition blow flow and hot-strip upper surface is 60o.
In view of air-flow easily loss in air, cause the variation of pressure and direction, be unfavorable for purging cleaning; Preferably, nozzle with the distance range 500mm～600mm of steel upper surface; Distance range 500mm～the 600mm of the investigative range front end of nozzle and cold/hot metal detector; Can useful effect thereby guarantee to purge air-flow.
The Surfaces of Hot Rolled Strip blow device that the utility model provides continues to blow high pressure draught to the hot-strip circulating, the iron scale of cleaning belt steel surface by being placed in the nozzle of cold/hot metal detector front end; Thereby avoid a large amount of iron scales to enter into the investigative range of cold/hot metal detector, have a strong impact on the track and localization to hot-strip, thereby promoted the location efficiency with steel.Adopt high pressure draught cleaning iron scale simultaneously, can avoid the damage to belt steel surface, thereby guarantee the rolling quality with steel.Purge the angle of air-flow, the distance of nozzle and hot-strip is set and all can be guaranteed that the air-flow of output can guarantee efficient effect, avoids the problems such as loss, has guaranteed sweeping efficiency simultaneously.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
