Description
Technical field
The utility model belongs to metallurgical technology field, relates to the device that is used to control the strip steel Zn-plating layer thickness in the band steel Continuous Hot Dip Galvanizing Line, particularly discloses a kind of edge dam that is used to improve strip steel Zn-plating layer quality.
Background technology:
At present, band steel Continuous Hot Dip Galvanizing Line all adopts the thickness of online air knife control strip steel Zn-plating layer, makes the galvanizing technique level obtain the raising of essence.Limit portion crosses zinc-plated as common one of insoluble problem in producing, and the major cause of its generation is: on the one hand, the atmospheric pressure that the fringing effect of air knife makes cutter lip both sides is low slightly than the middle part, causes air-flow that blowing of the strip edge portion zinc liquid power of scraping is descended; On the other hand, although air knife blows the unnecessary zinc liquid of wiping belt steel surface off, owing to zinc liquid ot-yet-hardened this moment, zinc liquid surface tension effects causes the zinc liquid film to converge to limit portion.The band steel of edge thickening easily produces holiday and the unequal quality problems of coat-thickness in roller coating technology, because the continuous accumulation of volume layer thickness can cause the grand high projection in coil of strip edge, webbing bears action of pulling stress and makes strip edge portion the shape wave defective occur when batching simultaneously.
Summary of the invention:
At above technical problem, the utility model provides a kind of edge dam that is used to improve strip steel Zn-plating layer quality.The utility model is formed by girder with by the left and right gas block panel that traversing guiding mechanism suspends thereon, and left and right gas block panel lays respectively at the both sides of band steel; Roller, equilibrator and cylinder are connected with left and right gas block panel.It is easy to make, and is convenient to install, and is fit to national conditions.
The technical scheme that the utility model adopted is: the edge dam device comprises girder and is connected the left and right gas block panel that suspends thereon by line slideway auxiliary, slide plate that gas block panel lays respectively at the both sides of band steel; By the roller that contacts with the strip edge edge and the acting in conjunction of equilibrator thereof, gas block panel dynamically keeps the constant distance with the strip edge portion of vertical operation.When strip width changes suddenly, can make gas block panel move apart strip edge portion by cylinder action to prevent collision.
After taking abovementioned technology, as depicted in figs. 1 and 2, owing to set up edge dam in band steel both sides, effect is equivalent to increase strip width, stopped the loss laterally of limit portion air-flow, make it the same clamping action that is subjected to two sidewinds, and keep limit portion air-flow to form stronger high pressure area, thereby it is zinc-plated excessively to suppress limit portion effectively with the middle part air-flow.If edge dam width surpass half of air knife and strip width difference, just can eliminate strip width in addition air-flow liquidate mutually and the high frequency noise that takes place, help improving Working environment.
The beneficial effects of the utility model are, it is zinc-plated excessively to suppress strip edge portion effectively, improves strip steel Zn-plating layer quality, improve the quality of product, and can eliminate air-flow to liquidate and the high frequency noise that produces; Simple in structure, easy to operate, be fit to national conditions.
Description of drawings:
Fig. 1 is that zinc-plated principle schematic is crossed by edge dam device inhibition limit portion;
Fig. 2 is Fig. 1 zinc coating synoptic diagram;
Fig. 3 is a structural representation of the present utility model.
Among the figure, part 1 is a girder, and part 2 is left gas block panel, and part 3 is right gas block panel, and part 4 is traversing guiding mechanism, and part 5 is the band steel, and part 6 is a roller, and part 7 is an equilibrator, and part 8 is a cylinder.
Embodiment:
2 embodiment of the present utility model is described in conjunction with the accompanying drawings:
Edge dam is installed on the air knife lifting transverse device, and the edge dam device comprises girder 1 and by traversing guiding mechanism 4 suspend thereon left gas block panel 2, right gas block panel 3, left and right gas block panel 2,3 lays respectively at the both sides of band steel 5; Traversing guiding mechanism 4 is made of line slideway auxiliary, and the track of line slideway auxiliary is fixed in girder 1 downside, and its slide block links to each other with left and right gas block panel 2,3, guides left and right gas block panel 2,3 moving in the horizontal direction; Equilibrator 7 is made of shift fork, line slideway auxiliary, counterweight and the guide wheel thereof etc. that are connected with left and right gas block panel 2,3, the guide rail of line slideway auxiliary is installed on the angled inclined-plane of girder 1 both sides and level, counterweight and guide wheel thereof are fixed on the slide block, the horizontal component of both sides counterweight passes through guide wheel---and shift fork passes to left and right gas block panel 2,3, keep running balance with the band steel by the horizontal force that two side wheels 6 pass to left and right gas block panel 2,3, wherein, the both sides counterweight can increase and reduce according to processing requirement; The cylinder part of cylinder 8 is articulated on the girder, and piston rod end connects with left and right gas block panel 2,3.
In-cylinder pressure is identical with ambient pressure during works better; When weld seam by the time, cylinder piston rod chamber air pressure increases, cylinder action drive left and right gas block panel 2,3 along traversing guiding mechanism 4 away from band steel 5.Edge dam is installed on the air knife lifting transverse device, but dynamic adjustments edge dam and the relative position of being with steel.
By the roller 6 that contacts with the strip edge edge and the acting in conjunction of the equilibrator 7 on the horizontal direction thereof, left and right gas block panel 2,3 dynamically keeps the constant distance with the band steel 5 limit portions of vertical operation; When continuous belt steel 5 has weld seam to pass through, can by 8 quick motions of weld joint tracking signal control cylinder make left and right gas block panel 2,3 away from the band steel 5 limit portion with prevent the collision.
The utility model requires the free retractility of two cylinders necessary good for the horizontal of distance steel going along with that guarantees baffle plate and strip edge edge moves, and the moving sets of 4 line slideway auxiliaries requires coplane.Actual when producing, counterweight how much depend on thickness and the rigidity of being with steel, can increase and decrease according to processing requirement.
It is excessively zinc-plated that the utility model can suppress strip edge portion effectively, improves strip steel Zn-plating layer quality, improves the quality of product, and can eliminate air-flow to liquidate and the high frequency noise that produces; Simple in structure, easy to operate, be fit to national conditions.The utility model can be widely used in the strip steel Zn-plating.
