Description
Technical Field
The utility model relates to a hot-galvanize wet finishing system technical field especially relates to a hot-galvanize wet finishing system sweeps device.
Background
The hot galvanizing wet finishing system mainly comprises a finishing machine and a withdrawal and straightening machine, wherein a set of cleaning and drying system is respectively designed in each of the two areas, so that the condition that redundant zinc powder is not attached to the surface of rolled strip steel and accumulated water is not remained is ensured, once the surface cleanliness of the rolled strip steel with mechanical property cannot meet the production requirement, edge passivation pollution can be generated in the subsequent roll coating process, the salt spray test is unqualified, and batch quality accidents are easily caused. On-site analysis shows that the surface of the strip steel can basically remove zinc powder and desalted water above 2/3 after finishing and straightening, but the mixed solution of the residual 1/3 zinc powder and desalted water is very easy to remain on both sides of the edge of the strip steel due to insufficient drying design capacity after straightening.
Because no redundant drying and purging system is arranged between the straightening and rolling, the production process is very passive because the edge of the strip steel frequently has water to cause the product quality defect and can not meet the requirements of downstream customers on the product quality.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a wet finishing system of hot-galvanize sweeps device can not only stabilize the use in succession, can reduce the purchase expense and the manual maintenance cost of this equipment spare part again, and the effectual solution draws and corrects back belted steel surface limit portion watermark and remains the problem.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model relates to a wet finishing system of hot-galvanize sweeps device, include that two sets of limit portions that add at withdrawal and straightening machine rear portion sweep the device, and are two sets of limit portion sweeps the device and is on a parallel with the belted steel that waits to sweep and arranges, and is a set of limit portion sweeps the device and is used for sweeping the upper surface of belted steel, and another group is used for sweeping the lower surface of belted steel, and is two sets of limit portion sweeps the device and connects an air supply pipe respectively, limit portion sweeps the device and includes a plurality of nozzles that set up towards belted steel surface and certain angle of slope.
Further, the spray angle of the nozzle is 45 °.
Furthermore, the limit portion sweeps the device and all includes one and blows the spray tube, blow the both ends of spray tube and be the blind end, blow the middle part of spray tube and connect the air supply pipe, blow the spray tube orientation belted steel one side evenly installed a plurality ofly the nozzle.
Furthermore, the middle of the blowing spray pipe is used as a center, and the spray nozzles on the two sides are symmetrically arranged.
Furthermore, the blowing nozzle is provided with at least 6 nozzles from one end to the other end.
Furthermore, the two groups of edge purging devices are respectively arranged above and below the steel strip.
Compared with the prior art, the utility model discloses a beneficial technological effect:
the utility model provides a wet finishing system of hot-galvanize sweeps device, the primary structure is upper and lower two sets of devices that sweep, guarantees through certain pressure control that belted steel surface does not have unnecessary watermark to remain, solves the belted steel surface both sides ponding problem that causes owing to drying capacity is not enough, and then influences the passivation process of follow-up product, causes the uneven production quality defects such as salt fog test disqualification of passivation, reduces the problem of product quality grade.
By adding the purging device, the problem that the watermark at the edge part influences the subsequent passivation effect is controlled, the product quality defect is solved, the purchase cost and the maintenance amount of the part of equipment are reduced, the production running cost is saved, and the qualification rate and the standard requirement of the product quality are improved.
