Description
Technical field
The present invention relates to a kind of method, belong to the silicon steel technical field with ultrasonic wave reduction oriented silicon steel iron loss.
Background technology
Silicon steel is indispensable important non-retentive alloy in electric power, the electronic industry, also is a kind of important energy saving Metallic Functional Materials.The oriented silicon steel that wherein is mainly used in transformer industry b referred to as the whole world steel " pinnacle of a pagoda product ", and the laudatory title of " special steel artwork " is more arranged.Silicon steel with core loss (iron loss) and magnetic induction density (magnetic strength) as product magnetic guarantee value, how to improve the magnetic property (comprising iron loss and magnetic strength) of oriented silicon steel better, make it have higher magnetic permeability, lower magnetostriction and core loss become one of heat subject of our times.And the complex manufacturing of oriented silicon steel, manufacturing technology strictness, external production technology is all strictly protected with the form of patent, is considered as the life of enterprise.The manufacturing technology of silicon steel and quality product have become one of important symbol of weighing national special steel production and development in science and technology level more.
On the silicon steel production technology, the refinement magnetic domain has become the third-largest technique means of continue control texture, attenuate steel band.Studies show that, can reduce the oriented silicon steel iron loss significantly by the refinement magnetic domain.At present, main refinement magnetic domain method has laser refinement magnetic domain, mechanical impression refinement magnetic domain, ionic fluid refinement magnetic domain or the like.Japan company of Nippon Steel adopts the laser radiation technology to make the Hi-B iron and steel decrease reduction about 15% (Hideo Matsuoka, Osamu Honjo.Current status and future prospects forelectrical steels[J] .Soft and Hard Magnetic Materials with Applications, 2000, (2): 1-6.); In the patent of the Europe and the U.S., also reported by localized heat distortion or the local magnetic domain thinning method that forms groove.And in China, refinement magnetic domain Study on Technology still is in the starting stage, Tsing-Hua University (laser processing method and the device of iron loss of silicon steel sheet " reduce " only, Gu Yuqin, Li Jingdong, cross and increase unit, Zhu Peifang, CN 1076492A), (Yang Yuling of Northeastern University Chinese patent publication number:, Sun Fengjiu, Zhang Ruifeng, Qi Xiaolong. the local laser nitrogenize improves the distribution [J] of oriented silicon steel domain structure. Northeastern University's journal, 2002,23 (2): 189-191.) etc. there was relevant report in several R﹠D institutions of minority.The essence of above-mentioned thinning method all is to introduce partial stress-strain district on silicon steel, and these change after handling can partly be retained in silicon steel inside, cause the rising of the energy of silicon steel own, thereby make silicon steel be in a metastable condition, silicon steel has by changing the trend that self domain structure reduces system's total energy like this, so magnetic domain generation refinement.And ultrasonic wave is just with the mode effect of introducing Local Stress Strain, thus be expected to the energy that is used for changing silicon steel inside by it, and then realize the refinement of magnetic domain, reduce its iron loss.And, more help industrial application because it is the finished product that acts on silicon steel.At present, utilize ultrasonic wave relevant research report not to be arranged as seeing of refinement magnetic domain means.This patent has very big meaning for the iron loss that the magnetic domain refinement technology of developing suitable China silicon steel production practical situation reduces oriented silicon steel.
Summary of the invention
The objective of the invention is to ultrasonic wave is introduced the subsequent disposal of finished product oriented silicon steel, and and then reduce its core loss value, a kind of method of using ultrasonic wave to reduce the oriented silicon steel iron loss is provided.Thereby, improve its magnetic property not destroying the reduction that coating for silicon steel sheet reaches its core loss value of realization under the prerequisite that does not cause the siliconized plate viscous deformation.
For achieving the above object, the present invention adopts following technical proposals.
Reduce the method for oriented silicon steel iron loss with ultrasonic wave, the oriented silicon steel sheet placed on the sample table 2, then on the oriented silicon steel sheet coated with flower SAMPLE 3, the shape of flower SAMPLE is selected the grid type flower SAMPLE for use, simulates the mechanism of mechanical score refinement magnetic domain method with this.Then sample table 2 is positioned in the aqueous solution 4, places the hard particles of some amount and size (can select) in the aqueous solution, and make the tool heads 1 of ultrasonic equipment be close to liquid level, promptly tool heads contacts with liquid level but does not immerse.Like this, when starting ultrasonic equipment, ultrasonic wave will inevitably drive the hard particles motion in the process of stirring solution 4, and hard particles will be played exposure place at the silicon steel sample with very big speed like this, thereby produces a very big reactive force.Simultaneously, sample table 2 can be moved by along continuous straight runs by a driven by motor, and movement rate is adjustable continuously.The kind by changing hyperacoustic power, hard particles and the movement rate of quantity, size and sample table 2 are realized the processing of different condition to the oriented silicon steel finished product.
In the aforesaid method, the grid direction of selected grid type flower SAMPLE is perpendicular to the rolling direction of silicon steel sample.The power of selected ultrasonic equipment is 500～1500W, and is adjustable continuously.Selected suspended particle kind has: boron carbide particles, white fused alumina particle, tungsten carbide particle.Size range is at 2 μ m-40 μ m.The selected concentration of aqueous solution that is suspended with hard particles is controlled at 50～150g/L.The selected treatment time is 10～60min.
