Containerless Net Shaping of Liquid Metals

The advantages and disadvantages of containerless net shaping of four liquid metals confined by electromagnetics are discussed. A new containerless net shaping procedure for liquid metal confined by high frequency electromagnetics, which combines containerless melting and electromagnetic shpaing, is presented. The principle of this containerless technique is divided into four steps which are described in detail. The shape of the equimagnetic flux density lines is in agreement with the electromagnetically induced shape of the liquid metal. The stability of the electromagnetically shaped of liquid metal is analyzed. Finally, some applications of this containerless technique are introduced.
