Abstract

A molten metal mold casting system with a cooling system which maintains an approximately equal coolant flow rate while altering flow characteristic of the coolant flow discharged toward the castpart to alter the cooling affects on the emerging castpart. The heat transfer at the center surface portion of the castpart is reduced for some low thermal conductivity alloy metals, which reduces the butt curl during casting.
