Abstract
Apparatus and method for casting metals and alloys using a pyrometer positioned outside or inside of a casting chamber and relative to a mold heating element in the casting chamber to view a region of a hot melt-filled refractory mold to improve accuracy of the mold temperature readings. The pyrometer is disposed at an elevation outside the casting chamber to view the mold along a viewing path above an induction coil and through an opening in a tubular susceptor disposed about the mold. Alternatively, the tubular susceptor and induction coil both include horizontal openings through which the pyrometer views the melt-filled mold from outside the casting chamber. The pyrometer is positioned to view a uniform profile region of the melt-filled mold having multiple mold cavities as the mold and susceptor are relatively moved.
