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 has a central longitudinal axis and includes a bore in communication with a port distributor having a greater radius with respect to the longitudinal axis than does the bore. Exit ports provide fluid communication between the port distributor and the exterior of the device. Each of a pair of larger exit ports has a larger cross-sectional area than does either of a pair of smaller exit ports.
