Abstract
A pour tube for casting molten metal is adapted to reduce turbulence and mold disturbances, thereby producing a more stable, uniform outflow. The pour tube includes a bore having a body in communication with an enlarged outlet portion. Exit ports in communication with the outlet portion have an offset design in which at least one wall of the exit port is tangent to a circle having a larger radius than the body of the bore.
