Definitions
- the invention relates to a method for producing a grain-oriented flat steel product with minimized magnetic loss values and optimized
- HGO material Flat steel products, also referred to in technical language as "HGO material", are steel strips, in technical language simply also “electrical tapes”, or
- Grain-oriented electrical steel or sheet is particularly suitable for applications in which a particularly low loss of magnetization is in the foreground and high demands are placed on the permeability or polarization. Such requirements exist
- SI / cs 100859WO September 2011 Steel flat products first of all a steel containing (in% by weight) typically 2.5 to 4.0% Si, 0.010 to 0.100% C, up to 0.150% Mn, up to 0.065% Al and up to 0.0150% N, and each optionally 0.010 to 0.3% Cu, to 0.060% S, to 0.100% P, to 0.2% each of As, Sn, Sb, Te, and Bi, balance iron and unavoidable impurities, to a starting material, such as a Slab, thin slab or a cast strip, potted. The starting material is then subjected, if necessary, to an annealing treatment to be subsequently hot rolled into a hot strip.
- a starting material such as a Slab, thin slab or a cast strip
- Decarburization annealing is usually significantly reduced to avoid magnetic aging of the carbon content of the cold strip.
- an annealing separator which is typically MgO, is applied to the strip surfaces.
- the annealing separator prevents the turns of a coil wound from the cold strip during the subsequent high-temperature annealing
- the steel flat product thus obtained is coated with an insulating layer, thermally directed and in one
- This final annealing can be done before or after
- Flat steel products generally have a thickness of 0.15 mm to 0.5 mm.
- flat steel products have a strongly anisotropic magnetic behavior.
- EP 0 409 389 A2 proposed further possibility of loss improvement is that on the surface of the flat steel product partial plastic deformations are generated. This can be done for example by a
- the losses are minimized by a suitable laser treatment.
- the loss of magnetization of a grain-oriented flat steel product with a typical nominal thickness of 0.23 mm for these products can be improved by more than 10% compared to the untreated state.
- the loss enhancements depend both on the properties of the base material, such as the grain size and texture sharpness, and on the laser parameters, to which the distance L of the lines along which the
- Laser beams are guided to the respective flat steel product, the contact time t dW eii and the specific

- Magnetostriction is the change in length of a
- the object of the invention was to provide a method for producing flat steel products, which are optimally suitable for the production of parts for transformers.
- a method of the invention for producing a grain-oriented flat steel product having minimized magnetic loss values and optimized magnetostrictive properties comprises the operations
- the invention in a
- the parameters of the laser treatment are varied so that the difference between the respectively detected before and after the laser treatment apparent power Si, 7 is less than 40%.
- NACH Laser treatment detected apparent power Si, so NACH meets the following condition:
- the increase in apparent power caused by the laser treatment is so limited in the present invention that the apparent power after the laser is not more than 40% as compared with its value at the same time
- the invention thus takes into account that in the design transformers usually not the
- the subject of the method according to the invention is thus an optimization of the laser parameters with regard to
- Samples of the flat steel product to be taken be determined according to the laser treatment and the parameters of the laser treatment, depending be varied from the result of this detection to these samples, the respective apparent power Si (7/5 o before and.
- This configuration allows the inventive method having a comparable
- the distance L of the linear deformations the exposure time t dwe ii of the laser beam, the specific energy density U s , the laser power P, the focus size As or the scan speed come v so in question.
- Laser beam is varied in the range of 1 x IGT 5 s to 2 x KT 4 s.
- Apparent power Si / 7/5 ° in the range of 200 - 3000 W can be varied.
- Fiber lasers have the particular advantage here of allowing close focusing of the laser beam.
- track widths of less than 20 ⁇ m can be achieved with a fiber laser.
