The topic of this paper is the unidirectional solidification of ternary Al7Si0.6Mg aluminium alloy in a rotating magnetic field of 30 -150 mT and the characterisation of effect of stirring on the solidified structure. During performing the experiment-series, one of the three solidification parameters (temperature gradient, solid/liquid interface velocity and magnetic induction) was continuously changed and the other two of them was kept on a constant value. The effect of these parameters on the developed structures was analysed during the evaluation of the experimental results. Moreover, the extent of Si-macrosegregation as well as the change of the secondary dendrite arm spacing were investigated on the longitudinal and cross-sections of samples as a function of the three basic parameters.

Electrical Efficiency

It is a fact that at present the focus in the area of new energy-saving electrotechnologies for heating of non-ferrous metal products is on induction heating in transverse magnetic field, but a large range of products with rectangular cross-section made of non-ferrous metals is not treated by heating method in a transverse magnetic field. Currently such products are heated in the induction heating installations in alternating longitudinal magnetic field though their electrical efficiency is not greater than 0.5. Attractiveness of heating of such products in the transverse rotating magnetic field of permanent magnets is in ist potential to achieve electrical efficiency equal to 0.75-0.85. The study of heating aluminum products with rectangular and cylindrical cross-sections to a temperature of 550 ° C is done and described.
