摘要： A method and apparatus for electromagnetic casting of metal and alloy ingots of desired shape having portions of small radius of curvature. A modified shield is provided which provides for a reduction of the electromagnetic field intensity at the corners of the forming ingot by increasing local screening of the field at the corners. Increased local screening at the corners is achieved by locally increasing shield depth, by providing for deeper displacement of the shield, by changing the shield section, or by changing the shield orientation. Also disclosed is a modified inductor which is shaped so as to be located at a greater distance from the portions of small radius of curvature of the ingots than from portions of the ingots adjacent to the portions of small radius of curvature. The modified shield may be combined with the modified inductor and/or with a coolant manifold to simultaneously modify and control coolant application elevation such that the elevation is a minimum at the corners of the ingot.

摘要： 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.

摘要： An apparatus and process for casting metals wherein the molten metal is contained and formed into a desired shape by the application of an electromagnetic field produced by a multi-turn inductor. The pitch or spacing of individual turns of the inductor is controlled to provide accurately varied electromagnetic pressure. The process includes the step of varying the distance between turns and/or the height of the individual turns to control the electromagnetic forces and balance the metallostatic pressure within the molten metal being cast.

摘要： A duplex impedance shield is disclosed which is used to effect improved shape control in the electromagnetic casting of molten metal or alloy. The shield is provided with a primary loop which substantially surrounds the upper portion of an electromagnetic casting station and a secondary loop attached thereto which serves to enlarge the air gap enclosed by the shield thereby increasing the impedance of the shield. The secondary loop of the shield may be provided with shunt means which can be manipulated to vary the inductance and/or the resistance of the shield thereby varying the impedance of the shield.
