Description
Technical Field
The utility model belongs to the technical field of the metallurgical equipment technique and specifically relates to a built-in straightener air-blowing device of area protection is related to.
Background
On a hot rolling line in the metallurgical industry, after the rolling of a steel plate is finished, the steel plate needs to be straightened by a straightening machine, so that the requirement on the unevenness of a finished steel plate is met. For steel plates of similar steel types Q345, AH36, Q390 and Q460 and with the thickness of 10-50mm, the surface temperature of the steel plates is reduced in the conveying process, a layer of iron oxide scale is generated, the iron oxide scale on the surface is seriously dropped in the straightening process, the iron oxide scale is pressed into the surface of the steel plates in the straightening process, the steel plates need to be polished or judged, part of the iron oxide scale drops into a lower roller box of a straightening machine in the straightening process, and a little iron scale is rolled between a supporting roller and a working roller along with the running of a roller system, so that the roller surface of the straightening roller and the supporting roller is damaged, the service life of the roller system is shortened, and the risk of surface quality of the steel plates in batches exists. In order to solve the problems, an external blowing device is additionally arranged on the outer side of a side guide plate of a straightening machine of a part of hot rolling line, but the steel plate can be warped in the process of straightening the thin plate, the external blowing device is impacted, the air blowing pipeline is impacted and falls off and then enters the interior of the straightening machine along with the steel plate, so that the risks of damage to a straightening roller, waste judgment of the steel plate and the like are caused, the air blowing pipeline of the external blowing device is arranged at a higher position for reducing the frequency of the impact of the external blowing device, and the blowing effect is poor in the using process.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the deficiency of the background art, the utility model discloses a built-in straightener air-blowing device of area protection.
The technical scheme is as follows: the utility model discloses a built-in straightener air-blowing device of area protection, include the side guide that atress frame bottom both sides set up on the straightener, the side guide bottom is equipped with the antifriction plate, first through-hole is seted up along the baffle extending direction in the side guide cross-section, install the air-blowing pipeline in the first through-hole, a plurality of second through-holes are seted up towards antifriction plate bottom extension interval to first through-hole, be equipped with the air-blowing nozzle in the second through-hole and with air-blowing pipeline intercommunication. After installation, the air blowing nozzle is arranged in the wear-resistant plate, so that the nozzle cannot be impacted by the warping head of the steel plate in the straightening process.
Further, the air inlet front end of the air blowing pipeline is provided with an air storage tank and a control valve group, and the air storage tank and the control valve group are used for stabilizing the pressure of compressed air and further improving the blowing effect.
Furthermore, the air blowing pipeline is connected by adopting an expansion joint when being spliced at the same side, and is used for compensating the deformation of the air blowing pipeline after the bending roll is applied to the straightening machine under stress.
Furthermore, the side guide plates are connected through guide plates by a plurality of rib plates arranged at intervals, the first through hole is formed in each rib plate, and an air supply blowing pipeline penetrates through the first through hole and is fixed through a fixing clamp pipe.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the air blowing nozzle is arranged in the wear-resistant plate, so that the warping head of the steel plate cannot impact the nozzle in the straightening process, and the problem that an air blowing pipeline of the straightening machine is impacted in the using process is solved; the height of an air blowing pipeline is reduced, the air storage tank is additionally arranged, the air blowing and blowing effects are greatly improved, and the foreign matter pressing-in amount of the surface of the steel plate is reduced by 60% after the steel plate is straightened by the straightening machine; the grinding frequency of the straightening roller is reduced, and the labor intensity of operators is reduced.
