ABSTRACT:
A casting mold (e.g., a cope and drag) is disposed on a drag slab having a sprue and a reaction chamber containing an alloyant to be selectively introduced into the melt as it is drawn through the reaction chamber during differential pressure, countergravity casting. A rubber formed between the mold and the drag slab communicates the reaction chamber to a plurality of narrow mold ingates that supply the melt treated (alloyed) in the reaction chamber to the mold cavity during countergravity casting.
