Description
Technical field
The utility model relates to a kind of pickling steel band and blows limit device.
Background technology
Pickling steel band is compared with ordinary hot strip rolling, and surface quality is good, is convenient to welding, oiling and japanning.Compare with cold-rolled steel strip, the advantage of pickling steel band is, guaranteeing, under the prerequisite of surface quality service requirements, effectively to reduce user's purchase cost, to be widely used in the industries such as automobile, machinery, light industry, building, has wide market outlook.
Hot rolled strip enters rinse tank the acid solution of its remained on surface is rinsed well after pickling tank pickling.But the travelling speed of current chlorohydric acid pickling unit very fast (>=120 ms/min), add rinse tank squeezing roller and extract the bad and Problem On Compressed Air With Water of effect, the hot-air drier of rinse tank outlet can not be dried the moisture of Edge of Steel Strip portion, cause the jaundice of pickling Edge of Steel Strip portion and get rusty, causing client normally to use.If rolling jaundice and the pickling coil of strip getting rusty, will pollute emulsion of rolling mill system, thereby affect the surface quality of cold-rolled steel strip.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to maintenance, in the process of acid washing of hot rolled steel strip, can not cause jaundice and the pickling steel band of corrosion defect to blow limit device.
For achieving the above object, the utility model adopts following technical proposals:
A kind of pickling steel band blows limit device, comprise the drum being connected with compressed air gas source, drum bottom is provided with the water shoot communicating with inside steam drum, drum top communicates with two blowpipes that parallel connection is arranged in casing, two blowpipes are arranged at respectively the upper and lower part of pickling steel band pending in casing, and two blowpipes are all parallel with pending pickling steel band, two blowpipes corresponding with pending pickling steel band are provided with some compressed-air atomizers, and the angle between described compressed-air atomizer and blowpipe and pickling steel band is 45o.
Described casing is that can be up and down along two blowpipe by-level positions separated two portions form, and the upper end in upper part is symmetrically welded two hoisting rings.
On the relative left and right side of described casing, be provided with the opening of function pickling steel band turnover with the corresponding section, by-level position of two blowpipes.
On described water shoot with discharge moisture valve.
Two blowpipes that described drum top is arranged in casing by compressed air line and parallel connection communicate, and each blowpipe is connected with compressed air line on pipeline and is equipped with a valve.
On each blowpipe, weld 8 compressed-air atomizers.
The beneficial effects of the utility model are: compare with the device of current oven dry pickling steel strip surface moisture, this device, with the drum of discharges compressed air moisture, has solved the problem with Problem On Compressed Air With Water that purges.With blowing of compressed-air atomizer, be in charge of upper and lower symmetrically, the angle between compressed-air atomizer and blowpipe, pickling steel band is 45o, can effectively dry up the moisture of pickling steel band upper and lower surface limit portion.Casing is divided into upper box and lower box, and at 2 hoisting rings of upper box upper surface both sides welding, if there is compressed-air atomizer, stop up or distortion, pressurized air valve before blowpipe can be closed, upper box hangs rear dredging or changes nozzle, has reached that to blow limit effective, the effect of convenient maintenance and replacement, solve the steel band jaundice and the corrosion difficult problem that in prior art, because of pickling Edge of Steel Strip portion, with water, cause, improved pickling steel strip surface quality.

Wherein, 1, compressed air inlet pipe; 2, drum; 3, water discharging valve; 4, water shoot; 5, pressurized air escape pipe; 6, pressurized air valve; 7, hoisting ring; 8, blowpipe; 9, compressed-air atomizer; 10, casing, 11, pickling steel band.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Pickling steel band blows limit device, comprises compressed air inlet pipe 1, drum 2, water discharging valve 3, water shoot 4, pressurized air escape pipe 5, pressurized air valve 6, hoisting ring 7, blowpipe 8, compressed-air atomizer 9, casing 10.As shown in Figure 1, wherein compressed air inlet pipe 1 is connected with drum 2, with the water shoot 4 of water discharging valve 3, be welded on the bottom of drum 2, by regularly opening the moisture in water discharging valve 3 discharges compressed air, pressurized air escape pipe 5 one end of band compression air door 6 are connected with drum 2, one end is connected with blowpipe 8, and 16 compressed-air atomizers 9 are symmetrically welded at two blowpipe both sides, and the angle between compressed-air atomizer 9 and blowpipe, pickling steel band is 45o.
Casing 10 is that can be up and down along two blowpipes, 8 by-level positions separated two portions form, and the upper end in upper part is symmetrically welded two hoisting rings 7.
On the relative left and right side of casing 10, be provided with the opening of function pickling steel band 11 turnover with the corresponding section, by-level position of two blowpipes 8.
When pickling is produced, open 6 pairs of pickling steel bands of pressurized air valve, the 11 residual moisture of upper and lower surface limit portion and dry up, improved purging effect and pickling steel strip surface quality.During maintain and replace, first closes compression air door 6, then by hoisting ring 7, hang out 10 pairs of compressed-air atomizers 9 of upper box and dredge and change, and improved maintenance efficiency.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
