Magnetic-Pulsed Separation of Sheet Metals

Abstract

The purpose of the article is to offer the method tool, the characteristic estimates, the theoretical analysis of the ongoing electrodynamic processes and the experimental testing aimed at substantiating the efficiency of magnetic-pulsed separation of two flat tightly adjacent conductive sheets in an inductor system with a rectangular solenoid placed on one of their surfaces. Methodology. For conducting the research, the methods for solving boundary electrodynamics tasks, the mathematical applications from the Wolfram Mathematica package, the experimental research methods in Mechanics and Applied Electrodynamics have been employed. Results. The analytical expressions for the spatiotemporal distribution of magnetic pressure forces in rectangular inductor systems which generate packets of low-frequency plane-parallel electromagnetic waves have been obtained. Successful experimental testing of the magnetic-pulsed separation of aluminum sheet samples confirmed the validity of theoretical conclusions. It was found that for the practical application of this production operation, sufficiently small values of exciting fields, as well as low voltage values on the capacitive energy storage of electromagnetic power sources $(\sim 0.5\ldots 1\ \text{kV})$ are required. Practical implications. The results obtained allow to put into practice effective magnetic-pulsed technologies of separating sheet metals in automated lines and their transportation directly to the processing zone.
