Abstract
A new process of horizontal electromagnetic casting (HEMC) described as non-mold casting is proposed in which the molten metal is levitated by imposing direct current and direct magnetic field. This process may be favorably applied to the casting of heavy metals, since strong electromagnetic force can be induced at the expense of a small quantity of electric energy. On the other hand, in case of the ordinary process of vertical electromagnetic casting (VEMC), a large amount of electric energy and cost of equipment are indispensable for casting a heavy metal. By using this process, the alloy of 56%Bi-40%Sn-4%Zn (M.P.=403 K, ρ=8.7×103 kg/m3) was cast to simulate the casting of molten steel, and the surface defects arising by the metal-mold contact could be eliminated.
Furthermore, the stability analysis is developed to confirm the applicability of this process and to determine the stable operating conditions.
