Cold-Mold Arc Melting and Casting

Description: Report issued by the U.S. Bureau of Mines providing updates and additional information related to cold-mold arc melting and casting. Abstract: "This bulletin reviews the historical background of the cold-mold arc-melting technology, with specific references to the development that led to homogeneous zirconium ingots. Descriptions are given of modern production arc-furnaces for vacuum melting of both exotic and conventional metals. Besides zirconium, specific data are given for production of chromium, thorium, and copper. The development of the skull-casting technique for titanium is detailed, and the application of the technique to such refractory metals as molybdenum and tungsten is described. Factors of operation of the apparatus and furnace design are considered" (p. 1).
