摘要： The method for reducing interstitial elements in alloy castings which comprises the following steps: pouring the alloy for the formation of a casting; and allowing said alloy to cool. According to the method, at least a peripheral region of the casting is heated, so that the flux of interstitial elements is caused towards the at least one peripheral region. The method is achieved where most of the interstitial elements concentrate in at least one region in the surface region of the casting. At later stages these elements can be easily eliminated from the respective regions by means of a thermal surface treatment or surface machining of the casting.

摘要： Disclosed is a mold structure for casting large metallic parts such as ingots so as to avoid the formation of the "shrinkage pipe" which normally develops on the exposed top surface of such castings during their solidification. The structure comprises a cap for placement on a mold which includes a diaphragm having a front surface located to intercept radiation emitted from the top surface of the cooling metal mass and to reemit radiation back thereto, and a means for returning radiation emitted from the back surface of the diaphragm such as an infrared reflector or a stack of baffles. The cap may include means for cooling the reflective surface and suitable ports which allow the interior of the mold and cap to be evacuated. Portions of the mold adjacent its open top may be provided with insulation to prevent heat loss from the metal by conduction. Various means for providing make-up heat to the top surface of the metal mass may also be included in the structure.

摘要： Molten metal is fed to an ingot during solidification, in order to compensate for shrinkage and segregation, by electroslag remelting (ESR). The electrodes are positioned entirely in the slag and comprise an inner electrode surrounded by an outer electrode, so that current flow is substantially horizontal through the slag. Powdered solid slag can be filled in the space between the electrodes before ESR begins; and for this purpose, the lower end of the outer or surrounding electrode is temporarily closed by a metal sheet which melts when the current is turned on, thereby to release molten slag onto the bath at the top of the ingot. The electrode arrangement is useful both with consumable and with nonconsumable electrodes.
