| titleOfInvention | A laminated steel tube yoke type uniform magnetization device |
| abstract | The invention belongs to the technical field of magnetic flux leakage detection of steel pipes, and discloses a laminated type steel pipe yoke type uniform magnetization device, comprising a coil, an iron core and a laminated type magnetic yoke. Connected to the power line, the lower end of the laminated yoke that is in contact with the surface of the steel pipe is in an arc shape, and the diameter of the arc is larger than the outer diameter of the steel pipe. The laminated magnetic yoke is connected by five pieces of steel plates. The middle steel plate is mirror-symmetrically arranged. There are two laminated yokes. The distances between the corresponding steel plates of the two laminated yokes are respectively d1, d2, d3, d4 and d5, and d1=d5<d2=d4<d3 , the two pieces of laminated yoke are mirror-symmetrically connected to the left and right ends of the iron core, and the two pieces of laminated yoke are also mirror-symmetrical about the coil, and the coil is arranged between the two pieces of said laminated yoke; the present invention The problem of uneven magnetization of the steel pipe in the prior art is solved, the consistency of the defect magnetic flux leakage detection signal is improved, and the invention is suitable for the magnetic leakage detection of the steel pipe. |
