Abstract
Two different techniques to provide electromagnetic full face edge containment have been developed for a vertical twin roll caster utilizing horizontal time varying magnetic fields. Magnets have been constructed for feasibility testing on static test rigs allowing up to 40 cm of liquid metal support. Results to date have shown that over 40 cm of liquid aluminum and approximate 31 cm of liquid Indalloy or steel can be contained using these techniques. Theoretical calculations have been made to predict the support expected for electromagnetic edge containment and experimental results have been presented for comparison to the calculated values. It has been shown that experimental results are reasonably well predicted by theoretical calculations. Tabl. 1, figs 6, refs. 6.
