Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Zinc-plated tape steel vibration damping device shown in Fig. 1 ~ 3, it comprises the some electromagnetic induction devices 2 be crisscross arranged in band steel both sides, and when mounted, place at band interval, the steel shake place left and right sides, spacing distance is 1.5 ~ 3 times of Galvanized Steel Strip 4 vibration wavelength; Electromagnetic induction device 2 is arranged in magnetic boots 3, and electromagnetic induction device 2 comprises iron core 2.1 and is wrapped in the ruhmkorff coil 2.2 on iron core 2.1 surface, and ruhmkorff coil 2.2 positive and negative electrode is connected with controller 6 respectively by control line 5, formation control loop.
When the utility model uses, being connected with frequency in ruhmkorff coil 2.2 is f1 alternating-current, current i 1, the magnetic field that the electric field changed changes, strengthened by iron core 2.1 magnetic force, magnetic boots 3 make magnetic line of force be evenly distributed, the electric field that the magnetic field of change changes, and the magnetic field of change changes on Galvanized Steel Strip 4 surface induced electricity eddy current 7.The approximate taper of crest of Galvanized Steel Strip 4 projection, current vortex 7 Relatively centralized, the field direction that current vortex 7 produces is contrary with the field direction that electromagnetic induction device 2 produces, due to homopolar-repulsion, Galvanized Steel Strip 4 projection is pushed up back, play the effect of stabilizing crest, when straight position got back to by Galvanized Steel Strip 4, repulsion reduces, electric current is reduced to i2, this Time Controller 6 reduces service voltage to U1, and the former raised position repulsion of Galvanized Steel Strip 4 is zero substantially, normal through.Equally, at the opposite side of Galvanized Steel Strip 4, electromagnetic induction device 2 principle of work is identical, and only the contrary crest in direction suppresses.Drive-motor 1 can drive magnetic boots 3 to tilt and horizontal experiencing small oscillating movements, keeps electromagnetic induction device 2 and the surperficial parallel equidistant of Galvanized Steel Strip 4 equilibrium state, makes to suppress vibration to reach best effect.When requiring not strict to the vibration of Galvanized Steel Strip 4, the alternating-current of constant frequency is directly connected with in ruhmkorff coil 2.2, when Galvanized Steel Strip 4 reaches equilibrium theory of tide, due to square being inversely proportional to of repulsion and distance, repulsion reduces rapidly, voltage need not be reduced by controller 6 again, also can reach predetermined effect.
Because the vibration of Galvanized Steel Strip 4 is inhibited, air knife can more near Galvanized Steel Strip 4 surface, thus make Galvanized Steel Strip 4 have good thickness uniformity consistency, reduce the consumption of galvanizing flux, after Galvanized Steel Strip 4 enters alloying furnace, because the minimizing of vibration, Galvanized Steel Strip 4 both sides all obtain consistent alloying, improve the resistance to bend of galvanized sheet product.
The utility model at home certain steel mill's galvanization production line comes into operation, galvanized sheet product average market valency is 4700 yuan/ton, the average price that before using this device, waste product is changed the original sentence to is 1800 yuan/ton, suppose galvanizing production annual production 18000 tons/year, disqualification rate 9.77%, after using this device, can bring benefits (4700-1800) × 18000 × 9.77%=510 ten thousand yuan.As can be seen here, zinc-plated tape steel vibration damping device designed by the utility model effectively reduces the vibration of steel band by electromagnetic repulsion force, because repulsion is large apart from short repulsion, distance repulsion is little, band steel Oscillation Amplitude is larger, inhibition is stronger, algorithm that need not be complicated, the suppression to the vibration of band steel can be realized, ensure air knife working stability, realize the uniformity of thickness of coating, ensure that the alloying level with steel two sides in alloying process reaches consistent simultaneously, effectively reduce the usage quantity of zinc liquid, to the zinc-plated production cost of reduction, the competitive power improving product has positive meaning, its market outlook are considerable, be applicable to promoting.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
