Abstract

See full text

To restrict to a low level a temperature gradient of an ingot immediately after solidification in a bottomless crucible in a electromagnetic induction casting method using an electrically conductive bottomless crucible. An upper section and a lower section of an electrically conductive bottomless crucible to be disposed inside an induction coil are configured as a water-cooled section and a non-water-cooled section. Both the water-cooled section and the non-water-cooled section are divided by vertical slits into a plurality of portions in a circumferential direction. Rapid cooling with water in the lower section of the crucible is restricted.
