- Abstract
This work examines the induction heating of a metal sheet to be used for multiple instance melt extraction from the lower edge. The task formulation of heating the edge in first place while keeping the release of Joule heat along that edge as homogeneous as possible, i.e., the avoidance of end effects, is solved numerically with a parametric study. A set of factors is also modeled physically in the framework of an experimental series. Subject to variation are (1) the extension of the copper block, which simulates the extraction wheel, in both directions parallel and perpendicular to the inductor; (2) the protrusion depth of the edge of the sheet below the lower face of the inductor; and (3) the shape of the inductor. It is shown that this shape adopted from the floating zone crystal growth technique in a previous work,[] albeit acting effectively, is removed from optimum. In this article, a more efficient solution is proposed. The numerical simulations also suggest that the vertical position of the inductor must be significantly above that one in Reference to increase the efficiency of the process. Reasonable conformity may be stated between the calculated and the experimental results.
