    Abstract: Metals castings, having a number of internal passageways which open at different surface portions of the castings, are mounted upon a horizontally axised wheel-like frame. The frame is intermittently rotated and momentarily stopped so that castings are rotated at times and stationary at times. During the times that the castings are stationary, they are simultaneously subjected to either an externally applied vibration or to a momentary, several millisecond long, high pressure burst of air through their respective passageways. The alternating vibrations and momentary bursts of air loosen and remove the sand and other casting debris contained within the passageways. Additionally, the changing angularity of the castings, due to the rotation, coupled with the vibrations and bursts of air, dislodge such sand and debris from the walls and, also, downwardly out of the passageways.

    Abstract translation: 具有在铸件的不同表面部分开口的多个内部通道的金属铸件安装在水平轴向的轮状框架上。 框架间歇地旋转并暂时停止，使得铸件有时旋转并且有时静止。 在铸件静止的时期，它们同时受到外部施加的振动或经过它们各自的通道的瞬间的几毫秒长，高压的空气爆发。 空气的交替振动和瞬间爆发会松动并清除通道内所含的沙子和其他铸件。 此外，由于旋转，铸件的变化的角度与空气的振动和爆裂相结合，将这些沙子和碎屑从壁上移除，并且还向下流出通道。

    Abstract: A system and methods are provided for removing core elements of cast components. In one embodiment, a method includes controlling a first high temperature autoclave cycle for a cast component in a vessel with a first solution concentration to remove at least a first portion of core elements, wherein the first solution concentration, temperature and pressure in the vessel are controlled to expose one or more casting pins in the cast component. The method may also include controlling a second high temperature autoclave cycle for the cast component in the vessel with second solution concentration, wherein the second solution concentration, temperature and pressure in the vessel during the second high temperature autoclave cycle are controlled to loosen one or more of the casting pins from the cast component, and controlling one or more low temperature autoclave cycles to remove core and casting pins from the cast component.
