ABSTRACT OF THE DISCLOSURE An apparatus and process is provided for electro- magnetically casting molten material into a desired shape. A containment zone is established. The con- tainment zone has a first section for electromagnetically containing the molten material and a second section down- stream and communicating with the first section for forming the molten material into the desired shape. The improvement comprises a heat extraction device for directing a cooling medium into the containment zone whereby the cooling medium passes the molten material in the second section to rapidly solidify the molten material prior to passing the molten material in the first section to lower the temperature in the contained molten material to minimize superheating. A second embodiment of the invention includes a secondary cooling device association with the heat extraction device for directing a cooling medium against the solidified material. A further embodiment provides an auxiliary cooling manifold device which may or may not be used in conjunction with the heat extraction device and the secondary cooling device. The auxiliary cooling device directs a cooling medium through the containment zone between the molten material and the device for estab- lishing a containment zone whereby the cooling medium is vented out of the upstream end of the containment zone.
