Device and method for measuring thickness of electrical steel

Abstract

The invention discloses a device and method for measuring the thickness of electrical steel. The device for measuring the thickness of the electrical steel comprises a first plane-parallel capacitor and a second plane-parallel capacitor, the first plane-parallel capacitor represents a first capacitance value when the electrical steel penetrates through two polar plates of the first plane-parallel capacitor, and the second plane-parallel capacitor is used for representing a second capacitance value when no other objects exist between two polar plates of the second plane-parallel capacitor. The relative area and the distance of the two polar plates of the first plane-parallel capacitor are equal to the relative area and the distance of the two polar plates of the second plane-parallel capacitor, and the first plane-parallel capacitor and the second plane-parallel capacitor are both connected to a data processing device. The data processing device is used for calculating the thickness of the electrical steel according to the first capacitance value and the second capacitance value. The thickness detecting precision of the device and method for measuring the thickness of the electrical steel is not influenced by dust, moisture, wind and other environmental factors, radiation hazards cannot be brought to the environment and a human body in the detecting process, and the device and method are convenient to use.

Description

technical field [0001] The invention relates to the field of electrical steel processing, in particular to an electrical steel thickness measuring device and a measuring method. Background technique [0002] Electrical steel, also known as silicon steel sheet, is an indispensable and important soft magnetic alloy for electric power, electronics and military industries, and is also the metal functional material with the largest output. It is mainly used as the iron core of various motors, generators and transformers. With the improvement of electrical steel processing technology and people's increasing requirements for the quality control of electrical steel products, the demand for electrical steel loss measurement and control is becoming more and more urgent. People are no longer satisfied with measuring the iron loss of electrical steel sheets with the Epstein square method in the laboratory, and require continuous on-line iron loss measurement. [0003] Iron loss is defi...
