Embodiment 1

[0021] Production of iron-based amorphous strips with a width of 106 mm. During the grinding process, add ethanol to grind MgO into a powder of 0.2-0.8 μm. Add 5 g of MgO powder to 2000 ml of deionized water to prepare a suspension, and then add silanol solution (3% to 32% metal alkoxide + 1% to 12% water + 0.001% to 0.01% hydrofluoric acid + solvent ethanol) to make insulating liquid. The amorphous strip 3 is thrown out from the crystallizer 1, formed into a strip under the action of the pressure roller 2, and passes through the coating device 4 composed of the small pressure roller 6 and the coating liquid box 5, and the insulating liquid is dip-coated on the amorphous strip. The surface of the material 3 is finally coiled by the coiler 9, and stays on the coiler for 30 minutes. In the iron-based amorphous strip with a length of 106mm, 14 points are taken to measure its thickness, and the distance between the 14 measurement points is the same. The measurement results are as ...

Embodiment 2

[0023] Produce iron-based amorphous strips with a width of 142mm. MgO is ground into a powder of 0.2-0.8μm under the action of ethanol. 5g of MgO powder is added to 2000ml of deionized water to prepare a suspension, and then add silanol solution Make insulating fluid. The amorphous strip 3 is thrown out from the crystallizer 1, formed into a strip under the action of the pressure roller 2, and passes through the coating device 4 composed of the small pressure roller 3 and the coating liquid box 5, and the insulating liquid is dip-coated on the amorphous strip. The surface of the material 3 is finally coiled by the coiler 9, and stays on the coiler for 30 minutes. In the iron-based amorphous strip with a length of 142mm, 14 points are taken to measure its thickness, and the distance between the 14 measurement points is the same. The measurement results are as follows image 3 As shown, the thickness of the amorphous strip varies from 1 to 2.5 μm after dipping the insulating la...

Abstract

Provided are a method and a device for online insulating coating on surfaces of an amorphous strip and a nanocrystalline strip. The device comprises a coating device, a temperature system, and a temperature controlling system. The coating device is used for dip-coating insulation coating liquid on the surface of the amorphous strip, the temperature system and the temperature controlling system control the temperature of the insulation coating liquid, the insulation liquid is dip-coated on the surface of the amorphous strip on line through the coating device after the amorphous strip is sprayed, and an electric insulation coating with uniform thickness is formed on the surface of the amorphous strip and is rolled up after being dried in the air. The coating is uniform in thickness, fine in dielectric strength, and can be formed at one step during strip production, and accordingly production efficiency is improved, while operation and production are facilitated..

Description

technical field [0001] The invention relates to the technical field of metal material surface treatment, in particular to a method and a device for online insulating coating on the surface of amorphous and nanocrystalline strips. Background technique [0002] Amorphous alloys have a high resistivity and an extremely thin oxide film. Usually, the coating process is not adopted, but as the application fields become wider and wider, the frequency of application scenarios continues to increase. High, the loss of amorphous alloy magnetic materials is gradually increasing, and the proportion of eddy current loss is increasing; in addition, when amorphous alloy is used in pulse power technology, it will encounter high frequency or even ultra-high frequency work If there is no suitable insulating material to insulate between the amorphous strip laminations, the heat-treated amorphous alloy core will produce interlayer breakdown. And cause the iron core to be useless. In such a cas...
