Abstract
A submerged entry nozzle for a continuous casting process includes a pair of triangular shaped ports that narrow from a top portion to a bottom portion of the ports. These triangular shaped ports may improve fluid flow at the discharge of the ports by increasing the velocity of the liquid steel exiting the nozzle and into the mold.
