Influence of the Intensity of Electromagnetic Mixing in Continuous Casting Machine Crystallizer on the Formation of Grade Blanks

The influence of the electromagnetic mixing (EMM) of liquid metal in the mold of the continuous casting machine on its thermal work, the formation of the structure and properties of cast billets are investigated. The influence of the current and frequency of EMM on the mechanical properties, macro-and microstructure of round and square sorted billets was established.

Optimized 3-D electromagnetic models of composite materials in microwave frequency range: application to EMC characterization of complex media by statistical means

The aim of this proposal is to demonstrate the ability of tridimensional (3-D) electromagnetic modeling tool for the characterization of composite materials in microwave frequency band range. Indeed, an automated procedure is proposed to generate random materials, proceed to 3-D simulations, and compute shielding effectiveness (SE) statistics with finite integration technique. In this context, 3-D electromagnetic models rely on random locations of conductive inclusions; results are compared with classical electromagnetic mixing theory (EMT) approaches (e.g. Maxwell-Garnett formalism), and dynamic homogenization model (DHM). The article aims to demonstrate the interest of the proposed approach in various domains such as propagation and electromagnetic compatibility (EMC).

Electromagnetic Mixing Laser Guided Mode and Laser Site Positioning

In recent years, Automatic Guided Vehicle (AGV), as a mobile robot, has been developed rapidly, especially with the rapid development of sensor technology, navigational technology has been widely used in the field of automatic guided vehicle. Meanwhile, the guidance mode has broken through the single way of track-laying and is developing towards a diversified direction. This paper elaborated the operating principle and the advantages of several commonly used ways of guiding, put forward the way of guiding which combined laser guidance with electromagnetic guidance and laser site positioning.
