“…The electromagnetic casting of copper alloys has received serious attention, 23 and some investigation of the electromagnetic casting of steel has been carried out (e.g., Reference 27). With both these metals, there is the problem of higher density and, with steel, a much lower electrical conductivity.…”

Electromagnetic casting is used within the aluminum industry to cast approximately two million ton per year of metal. It is a semicontinuous casting operation where the metal is solidified without contacting a mold. Consequently, the surface of the ingot does not have the imperfections that mar the surface of ingots cast using other technologies. This paper reviews the development of the technology and examines the fundamental phenomena governing the operation of the caster and the structure of the ingots cast.

Based on analyses for the electromagnetic pressure on the melt and the heat induced in the melt, the ratio of heat to pressure Q 0 /P m is de®ned, to give the relationship between Q 0 /P m and the thickness a, the electromagnetic parameter (mg) of the melt and the electric current frequency f under the electromagnetic con®nement and shaping process. If Q 0 /P m is large, any adjustment to the melt shape will easily cause a variation of the temperature in the melt. In this situation, there appears to be a more sensitive interaction between the shape and the temperature ®eld and a more narrow adjustment range for the process. Experiments on thin plate samples with a cross-section of 6 mm £ 18 mm are done with two kinds of induction coils. The results show that when a coil with a trumpet inside wall is used and the positions of the melt top and the S/L interface are properly selected, the melt periphery is nearly vertical and the temperature gradient ahead of the S/L interface is high. Under these conditions, a more stable and wider coupling between the shape and the temperature ®eld is continuously maintained and samples with a smooth surface and unidirectional crystals are successfully obtained. q
