Abstract
The utility model relates to a continuous hot galvanizing device, in particular to a continuous hot galvanizing device utilizing an electromagnetic enclosed slot device without a sink roll. An enclosed slot trough is arranged at the bottom of a zinc pot, the rectangular magnets A and B are positioned on the outer sidewall of the enclosed slot trough, and the rectangular magnets A and B produce a static magnetic field with the direct current or are permanent magnets. The electrodes are electrified with the direct current, and the static magnetic fields produced by the direct current and the rectangular magnet B are interacted with each other in a defined region, so that the metal solution in the enclosed slot trough receives an upward electromagnetic force and keeps a moving balance. Since the enclosed slot trough adopts a nonmagnetic conductive material, the effect of the electromagnetic enclosed slot is realized, enclosing the metal solution flow. Strip steels enter from the bottom. The utility model realizes the continuous hot galvanizing production process, eliminates the inconvenient factors brought to production by the erosion of the sink roll and the cover tile, and can change the variety of the galvanizing solution on line, making the continuous hot galvanizing production flexible.
Description
Technical field
The utility model relates to the continuous hot galvanizing device, relates in particular to a kind of continuous hot galvanizing device that adopts the electromagnetic enclosed slot device.
Background technology
At present band steel pot galvanize production process mainly comprises: raw sheet preparations → plating pre-treatment → hot dip process → plating aftertreatment → inspection after construction etc., wherein to cross be the core of pot galvanize production in hot dipping.Band steel heat is crossed in the zinc production process, and the sinking roller is immersed in the zinc liquid all the time, is the deflector roll of a no transmission, drive by band steel and roller surfaces frictional force fully,, perhaps produce relative movement in case therefore roll surface has deviation slightly, belt steel surface scratches at once, has influenced the galvanized sheet surface quality.Renewal and research emphasis about the continuous belt steel hot-galvanizing equipment concentrates on the device that the improvement or the employing of sinking roller are not had the sinking roller at present.For the method for improving the sinking roller as prolonging sinking roller shell watt work-ing life, improve the flat clean degree in sinking rod surface etc., because the sinking roller is a high temperature steel, sinking roller in the zinc pot can constantly be subjected to the erosion of zinc liquid in process of production, the flat clean degree in surface is difficult to guarantee, cause belt steel surface to scratch, and the axle sleeve watt of sinking roller rotates and the erosion of zinc liquid can be quickened the wearing and tearing of roller and axle sleeve watt in zinc liquid high speed, work-ing life is short, only about 5-20 days, cause the sinking roller frequently to change, not only reduce production efficiency, and labour intensity is big, brings inconvenience to production.After sinking rod (comprising stable roller) and support thereof were corroded by zinc liquid, ferro element is molten had in a large number influenced purity as zinc liquid, and band steel pot galvanize quality product can't be guaranteed.About adopting nothing sinking roller galvanizing technique to report, because the deformable of metal liquid is flowed, the bottom envelope flows feasible in theory but actual being difficult to realizes.Chinese invention patent " the electromagnetism blocking device that the hot dipping aqueduct is used " (CN 1154721A) discloses a kind of technical scheme, but this scheme adopts the high frequency magnet coil, the structure more complicated, and envelope stream effect is unsatisfactory.
Summary of the invention
The utility model provides a kind of electromagnetic enclosed slot continuous hot galvanizing device, cancelled the sinking roller drive mechanism in the zinc pot, eliminated in the zinc pot because the many unfavorable factors of sinking roller strap and the influence of roller of sinking strip surface quality, realize not having sinking roller electromagnetic enclosed slot continuously dip coat zinc technology, reduce labour intensity greatly, enhance productivity and make the zinc-plated kind of online change become possibility.
The utility model is achieved in that a kind of electromagnetic enclosed slot continuous hot galvanizing device, comprise the band steel, stablize roller, air knife, the zinc pot, offer an envelope chute at the zinc pot bottom, a pair of air knife is arranged above the zinc pot, above air knife, be provided with and be used for the stable roller of stabilized zone steel, this electromagnetic enclosed slot continuous hot galvanizing device also comprises yoke, rectangular magnet A, rectangular magnet B, the zinc nose, guide roller and DC electrode, outer wall is provided with a pair of magnetic pole over against the rectangular magnet B that is provided with in the envelope chute left and right sides, the magnetic pole of the magnetic pole of rectangular magnet A and rectangular magnet B is provided with on the contrary, lay respectively at the above and below of rectangular magnet B, the all logical direct current of rectangular magnet A and rectangular magnet B produces static magnetic field, or constitute by permanent magnet, the outside of rectangular magnet A and rectangular magnet B is provided with yoke, outer wall at the fore-and-aft direction that seals chute is provided with a pair of DC electrode, below sealing chute, a zinc nose is arranged, over against envelope chute below the guide roller that is used for being with steel importing envelope chute is arranged in the zinc nose.
In the above-mentioned electromagnetic enclosed slot continuous hot galvanizing device, described envelope chute is made by no nonmagnetic electrically conductive material, and envelope chute width is 5-100mm, and length is regulated by strip width.
The utility model is provided with DC electrode in envelope chute both sides, direct current is by zinc liquid, because zinc liquid is conductor, it is original because zinc hydrostatic pressure power has downward movement tendency, but under the static magnetic field effect of the direct current that DC electrode feeds in the regulation zone and by rectangular magnet B generation, zinc hydrostatic pressure power forms transient equilibrium in electromagnetic force that produces and the coating bath, the envelope chute adopts no nonmagnetic electrically conductive material, played the effect of stable envelope stream, reach and stop the effusive effect of zinc liquid, seal the zinc liquid in the zinc pot bottom envelope chute, realized electromagnetic enclosed slot; Rectangular magnet A as magnetic field effectively the accommodation zone steel depart from trend because of being subjected to rectangular magnet B influence of magnetic field, thereby guaranteed that the band steel enters from the zinc pot bottom, realize electromagnetic enclosed slot continuous hot galvanizing production process.Eliminated in the zinc pot because many unfavorable factors that the existence of sinking roller brings have not only been improved the galvanized steel surface quality, and made the zinc-plated kind of online change become possibility.
