摘要： A mold system and method for producing a casting. The mold system utilizes multiple channels, each channel comprising a sprue and gating system, to feed the mold cavity at different heights. When a lower portion of the mold is filled, a controller is signaled to initiate filling of the mold through a second channel positioned above the lower portion. This mold system desirably provides the hottest molten metal to the last portion of the casting to freeze with or without the use of risers, eliminating casting defects. The system also enables the controlled pouring of dissimilar metal castings.

摘要： A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.
摘要翻译： 制造等轴熔模铸造的方法。 该方法利用超声波发生器在熔模铸造模具中将超声脉冲发送到熔融金属中。 熔模铸造模具位于具有低输出感应线圈的炉的工作区域中，用于在熔融金属中产生对流电流。 超声波脉冲将从模具表面向内生长的树枝分离成熔融金属。 相反，等轴晶粒可以在熔融金属内成核。 此外，超声脉冲和低输出感应线圈使熔融金属循环，因为溶质被凝固等轴晶粒排斥。 混合减少了固化合金中的偏析效应，有助于成核等轴晶粒。
