Abstract
The invention discloses an alternating electromagnetic zinc smearing method, which comprises the following steps of: A, introducing three-phase alternating current to an electromagnet arranged in a zinc smearing device; B, taking out a steel tube from a zinc bath, conveying the steel tube to the zinc smearing device through an insulating clamp, and making the steel tube uniformly and horizontally pass through the magnetic force line range of the electromagnet arranged in the zinc smearing device; and C, taking down the steel tube from the clamp. The coating is uniform after the zinc is smeared, and the zinc smearing effect is good; and molten zinc is not oxidized or atomized in the zinc smearing process, so the molten zinc is saved, the molten zinc is prevented from being dissipated to the air, and the air is not polluted.
Description
Technical field
The present invention relates to a kind of zinc device of smearing, relate in particular to a kind of alternating electromagnetism and smear zinc method and device thereof, belong to the metal material surface manufacture field.
Background technology
At steel, in the Industrial processes of iron galvanizing, after galvanized pipe comes out from the zinc pot, its surface has often became uneven of zinc coating, and thickness does not generally all meet processing requirement, enterprise is general to adopt traditional airblade device to erase for unnecessary zinc liquid, its principle of work is to utilize high pressure gas that the unnecessary zinc liquid in surface is blown away, but this way can't be stopped surperficial plating layer situation in uneven thickness, high pressure blow-gas also easily makes zinc liquid oxidation and atomizing, zinc liquid oxidation meeting causes the waste of metallic zinc, and the atomizing of zinc liquid makes zinc liquid permeate in the air polluted air, environmental quality caused seriously influence, further harm humans is healthy.
The patent No. is that 200720035840.7 Chinese patent discloses a kind of steel-wire galvanizing and smears and wipe away device, be that electromagnetic generator is housed around the steel wire that goes out the zinc pot, electromagnetic generator comprises electromagnetic induction coil and current control device, the output of current control device links to each other with electromagnetic induction coil, electromagnetic induction coil is shape in the shape of a spiral, and galvanized steel wire passes from the electromagnetic induction coil center.Electromagnetic generator produces alternating magnetic field or pulsed magnetic field around steel wire, and at zinc laminar surface generation induced current, alternating magnetic field or pulsed magnetic field and induced current interact and produce long-range navigation magnetic force, make zinc laminar surface zinc liquid pressurized all around, and and the gravity acting in conjunction, impel zinc liquid to reflux, thereby reduce galvanized layer thickness.This device can not produce zinc liquid oxidation and atomizing, and it is effective to smear zinc; But the collaborative gravity acting in conjunction of the long-range navigation magnetic force that this device produces is in zinc liquid, and controllability and poor stability cause reliability not high.
Summary of the invention
The present invention is for solving the prior art problem, provide a kind of pollution less, effective alternating electromagnetism smears the zinc method.
Technical scheme of the present invention is: a kind of alternating electromagnetism is smeared the zinc method, it is characterized in that: may further comprise the steps:
A, the electro-magnet that is provided with in smearing the zinc device feed the three-phase alternation;
B, steel pipe is taken out from the zinc pond, send into by the insulation anchor clamps and smear the zinc device, and make steel pipe pass the magnetic line of force scope of smearing electro-magnet in the zinc device with the average rate level;
C, steel pipe is taken off from anchor clamps.
When three-phase alternation sinusoidal current passes through electro-magnet, electro-magnet produces alternating magnetic field, the intensity in magnetic field and direction all are sinusoidal variations, when steel pipe is inner by electro-magnet, the magnetic line of force of alternating magnetic field is through steel pipe and the zinc liquid that is in steel tube surface, produce induced current in steel pipe and zinc liquid, faradic intensity and direction all are sinusoidal variations, and the magnetic field of out of phase produces different induced currents; The invar pipe is insulated anchor clamps and fixes, and tangential movement, and induced current is in the magnetic field of electro-magnet, the horizontal resection magnetic line of force is subjected to the action of a magnetic field, produces long-range navigation magnetic force, zinc liquid under the effect of long-range navigation magnetic force, overcome and steel pipe between cohesive force begin to move in the other direction to the steel pipe progressive; Electro-magnet has certain thickness, and input is three-phase alternation sinusoidal current, therefore the magnetic field of the magnetic field of electro-magnet inner ring generation and outer ring production has certain phase difference, the long-range navigation magnetic force difference that out of phase produces, and the direction of power is pointed to retarding phase by leading phase, make zinc liquid be subjected to impellent, unnecessary zinc liquid is moved, and reaches the purpose of the zinc liquid of erasing; Because magnetic field is constant, the movement velocity of steel pipe in magnetic field is constant, the virtual value of the induced current that produces in the zinc liquid is constant, corresponding long-range navigation magnetic force constant, and zinc liquid is relative with the cohesive force between the steel pipe constant, agravic participation in the process of erasing, therefore unnecessary zinc liquid is after overcoming cohesive force and being erased, and remaining zinc liquid thickness is even; And if gravity and the acting in conjunction of long-range navigation magnetic force, then the traffic direction of steel pipe is necessary for and is tilted to, the length of steel pipe is shorter, the effect of gravity can cause the zinc liquid of steel pipe front end and upper end thinner, the zinc liquid of steel pipe rear end and lower end is thicker, it is relatively poor to smear the zinc effect.
As preferably, the cross section of described electro-magnet is the C font, and described steel pipe passes from electro-magnet inside.
As preferably, described steel pipe is 2 ~ 5m/min by the speed of electro-magnet.
As preferably, three-phase alternation electricity is sinusoidal waveform, and the current peak size is 15-30A.
Alternating electromagnetism is smeared the zinc device, it is characterized in that: comprise and smear the zinc device, the described electro-magnet that is provided with long strip shape in the zinc device of smearing is provided with coil winding in the described electro-magnet, and this coil winding is plane formula, spiral or column type; The cross section of described electro-magnet is the C font; Described alternating electromagnetism is smeared the zinc device and is also comprised alternating source, and described alternating source is connected with described coil winding, and this alternating source is imported three-phase alternating current to coil winding.
In sum, the present invention has the following advantages:
1, smear zinc after coating even, it is effective to smear zinc;
2, smear in the zinc process, zinc liquid oxidation and atomizating phenomenon can not occur, saves zinc liquid, avoids zinc liquid to be dissipated in the air simultaneously, can not pollute air;
3, equipment and steel pipe are contactless, do not need unnecessary maintenance, and equipment life is long, the reliability height, and running cost is low;
4, it is identical the inner and outer wall of steel pipe to be smeared the zinc effect, can smear zinc to the position that some traditional air knives can't go deep into.
