Abstract
A process for electromagnetically casting molten material into a thin strip having a substantially constant thickness. An inductor is provided for electromagnetically shaping the molten material. The material is electromagnetically shaped into a strip having a desired thickness. Variations in the thickness of the molten material are automatically reduced during the shaping step by selecting the frequency of the current applied to the inductor so that the thickness of the strip is about 1.8 to about 2.6 current penetration depth.
