Description
Technical field
The utility model relates to the parts on metallurgy industry hot rolling slab production line, refers to a kind of hydraulic elevation type hot rolling slab dephosphorize by high pressure water device particularly.
Background technology
Iron and steel is oxidized at high operating temperatures, forms iron scale and the phosphorus skin of one deck densification on its surface.If before the rolling can not by this layer of iron scale removing, in the operation of rolling, they can be pressed into belt steel surface by roll, affect its surface quality; Residual iron scale also can accelerate the wearing and tearing of roll, reduces the service life of roll.Moreover, as band steel need pickling time, residual iron scale can increase the difficulty of pickling, increases acid consumption.Therefore, before billet rolling, the iron scale on surface must be removed.The most current effective way utilizes the impulsive force of water under high pressure to remove removing iron scale and dephosphorize by high pressure water at present.
Along with the use of hot rolling slab dephosphorize by high pressure water in CSP continuous casting and rolling or hot rolling line is increasingly extensive, in order to obtain better phosphor-removing effect, often adopts and increasing operating pressure, and ignoring the control to height between nozzle and slab.In fact the mechanism of dephosphorize by high pressure water and the impulsive force of unit are have much relations.Research shows, when operating pressure and spray angle α invariable when, suitably control the height of nozzle and steel slab surface well, will significantly improve injection stream striking capabilities and phosphor-removing effect.Moreover, due to same hot rolling line, hot rolling slab supplied materials specification difference, iron scale thickness, compactness extent are also not quite similar, and for guaranteeing that nozzle is from the uniformity of steel slab surface distance and optimality, just need dephosphorize by high pressure water collector can have the function of self-control height.
But domestic and international dephosphorize by high pressure water device spray thrower is mostly and maintains static at present.The patent No. is that the Chinese utility model of ZL200320108138.0 discloses a kind of lift device for dephosphorization upwelling high-pressure water pipe, this device is made up of upper spray boom and elevating mechanism, elevating mechanism drives worm speed reducer by motor, worm speed reducer connects with screw screw mandrel, and upper spray boom is connected with screw-threaded shaft elevator structure.There is following problem in this device in application process: one is in screw mandrel lifting, decline process, and the existence because of Mechanism Clearance causes locating inaccuracy; Two is that site work environment is severe, and iron scale, dust are more, screw mandrel screw easily occur stuck, repair and maintenance cost is high.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect that existing lift device for dephosphorization upwelling high-pressure water pipe exists, provide a kind of can registration, hydraulic elevation type hot rolling slab dephosphorize by high pressure water device that maintenance cost is low.
For achieving the above object, hydraulic elevation type hot rolling slab dephosphorize by high pressure water device designed by the utility model, comprise the spray thrower be arranged on above hot rolling slab rollgang, described spray thrower is provided with some hydraulic sprays, the two ends of described spray thrower are separately fixed on a pair collector base, its special character is: also comprise a pair fixed support being arranged on hot rolling slab rollgang both sides, described fixed support is provided with lifting hydraulic cylinder, the cylinder body base of described lifting hydraulic cylinder and fixed support are fixedly linked, the hydraulic push rod of described lifting hydraulic cylinder is fixedly linked with corresponding collector base, the hydraulic push rod of both sides is respectively arranged with displacement transducer, and the signal end of institute's displacement sensors is connected with the PLC of dephosphorization system, thus controls a pair lifting hydraulic cylinder synchronization lifting, realizes the accurate control that spray thrower moves up and down distance.
Further, one end that described spray thrower is positioned at hot rolling slab rollgang transmission side is connected with extraneous high-pressure water pipe by water pipe head and supporting seal washer thereof, and one end that described spray thrower is positioned at hot rolling slab rollgang fore side is enclosed construction.
Further, described spray thrower is cylindrical, and described hydraulic spray is equidistantly arranged on bottom spray thrower.
The utility model has the advantage of: achieve the steady adjustment of spray thrower height by adopting the lifting hydraulic cylinder of both sides inbuilt displacement sensor and accurately locate, thus ensure that the best hitting power of injection stream, improve dephosphorize by high pressure water effect, reduce product and remove because of iron scale the quality thoroughly do not caused and change the original sentence to; This device convenient operating maintenance, avoids the jam phenomenon that conventional high-tension water dephosphorization mechanical type lifting device occurs, has saved maintenance cost, alleviated maintenance load.
