Abstract

The invention provides a plug-in cylindrical traveling wave magnetic field sensor for casting, and relates to a magnetic field sensor, which solves the problems of low mold-filling capacity on metal, and low metal solution feeding capacity during metal solution solidification of the conventional magnetic field sensor. N iron-core magnetic pole tooth discs and 3M iron-core magnetic yoke discs of the magnetic field sensor are arranged compactly; the upper end and the lower end of the magnetic field sensor are provided with the iron-core magnetic pole tooth discs; a set of electromagnetic coils are wound on the iron-core magnetic yoke disc between two adjacent iron-core magnetic pole tooth discs; K sensing areas are divided between the two iron-core magnetic pole tooth discs at the top end and the bottom end of the magnetic field sensor; each sensing area is provided with one or more iron-core magnetic yoke discs; and one or more iron-core magnetic pole tooth discs are arranged between adjacent sensing areas. The plug-in cylindrical traveling wave magnetic field sensor for casting is applicable for the process of casting precision accessories and parts.

Description

technical field [0001] The invention relates to a magnetic field inductor. Background technique [0002] With the rapid development of modern science and technology, cast aluminum alloy, as a traditional metal material, still occupies an important position in aviation, aerospace, automobile, machinery manufacturing and other industries due to its low density and high specific strength. With the traction of social needs and scientific and technological progress, especially in recent years, due to the requirements of sustainable development strategies and increasingly stringent environmental protection regulations, industries such as aviation, aerospace, automobiles, ships, weapons, and electronics require reasonable parts structure and reduced weight. Achieve little or no cutting to reduce costs and increase productivity. In compliance with such requirements, aluminum alloy precision castings are developing in the direction of large, thin-walled and integral parts. The prod...
