Abstract

The invention relates to a method for measuring macroscopic texture of high-magnetic induction oriented electrical steel, which is applicable to detection of the high-magnetic induction oriented electrical steel with the average sample grain size of above 10mm. The method comprises the following steps: acquiring a synthetic sample and a contrast sample; measuring an incomplete pole figure of the synthetic sample and determining an orientation distribution function; obtaining the macroscopic texture of the high-magnetic induction oriented electrical steel. Through reasonable distribution of the samples and mathematical transformation, the representativeness of a result and the working efficiency can be significantly improved, so that the method can be widely applicable to the fields of production and research of the high-magnetic induction oriented electrical steel for an electrical transformer.

Description

Technical field:

[0001] The invention relates to a method for measuring macroscopic texture, and more particularly relates to a method for measuring macroscopic texture of high magnetic induction oriented electrical steel. Background technique:

[0002] In power systems, high-voltage large-scale power transformers generally use high-inductance oriented electrical steel laminations to make cores. The magnetic performance level of oriented electrical steel is directly related to the volume and loss of transformer cores. Determining the macroscopic texture of silicon steel sheets can be used The magnetic properties of the sample, especially the magnetic induction of the sample, can be reflected from the structural information inside the material. In oriented electrical steel as a face-centered cubic fcc metal, the common feature of {100}<001> cubic texture and {110}<001> Gaussian texture is the <001> direction which is easy to conduct magnetism, which is benef...
