Problems solved by technology

[0003] At present, there have been a lot of researches on the influence of grain size on the magnetic properties of non-oriented silicon steel at home and abroad, but the relationship between grain size and magnetic properties has only been examined qualitatively from the aspects of average grain size statistics and impact mechanism. It can reveal the relationship between grains of different sizes and the magnetic properties of non-oriented silicon steel from a quantitative point of view, and there are few domestic and foreign researches on establishing mathematical models to analyze this problem

Abstract

The invention relates to a method for analyzing the influences of grain sizes on the magnetic performance of non-oriented silicon steel on the basis of principal component regression analysis. The method comprises the following steps: measuring the content of grains with different size ranges in the non-oriented silicon steel; standardizing all data; performing dimension reduction on the content data of the grains with different size ranges; calculating a characteristic value and determining a principal component and an expression thereof; performing regression analysis and performing significance testing on a regression equation; and converting the regression equation into a multivariate linear relation between the contents of grains with different size ranges and the magnetic performance of the non-oriented silicon steel by using inverse operation of a standard difference standardization method. According to the method, a multivariable program can be analyzed effectively, and the multivariate linear relation among variables is analyzed quantitatively by acquiring major information from complicated influence factors so as to quantitatively reflect the rule of the influences of the contents of grains with different size ranges on the magnetic performance of the non-oriented silicon steel, so that oriented guidance is provided for the practical production of efficient electrical steel products with low iron losses and high magnetic induction.

Description

technical field [0001] The invention belongs to the technical field of performance control of non-oriented silicon steel, and in particular relates to an analysis method based on principal component regression analysis of the influence of grain size on the magnetic properties of non-oriented silicon steel. Background technique [0002] With the rapid development of electric power, telecommunications and other industries, all kinds of generators, motors, compressors and other products are required to be high-efficiency, high-precision, and miniaturized to meet the standards of energy saving and environmental protection. Non-oriented silicon steel is an important material for manufacturing these products. Materials are increasingly required to have excellent magnetic properties with lower iron loss and high magnetic induction. Relevant studies have shown that grain size is the main factor affecting the loss of non-oriented silicon steel. Analyzing the influence of grain conten...
