To provide an apparatus and method of unidirectional solidification casting that produces a uniformly controlled cooling rate.
Molten metal is injected uniformly into a mold 10 from a feed chamber 34 in a horizontal or vertical direction at a controlled rate on top of the metal already within the mold. A cooling medium is applied to the bottom surface of a base material, with the type and flow rate of the cooling medium being varied to produce a controlled cooling rate throughout the casting process. The rate of introduction of molten metal and the flow rate of the cooling medium are both controlled to produce a relatively uniform solidification rate within the mold, thereby producing a uniform microstructure throughout the casting, and low stresses throughout the casting.
