Abstract:
1. An apparatus for centrifugally casting an object from molten metal, said molten metal having a liquidus arrest temperature and, when poured, a pour temperature, comprising a rotating mold; a trough positioned to receive poured molten metal; a drive system coupled to at least one of said trough or mold; a controller for controlling said drive system; a computer programmed with a transfer function relating fluidity calculated from a measured liquidus arrest temperature and a measured pour temperature to control of said drive system to provide prescribed movement of said mold and said trough relative to one another, said computer in communication with said controller; a first temperature sensor positioned to measure said liquidus arrest temperature of said molten metal and operable to communicate said measured liquidus arrest temperature to said computer; and a second temperature sensor positioned to measure said pour temperature of said molten metal and operable to communicate said measured pour temperature to said computer.
