Abstract
A submerged nozzle has a lower part with a bottom and two outlet side channels above the bottom, and a skirt with a center fixed to the lower part of the nozzle above the outlet side channels. The skirt has two parallel flat surfaces each having side edges that are smoothly connected to each other by two respective cylindrical surfaces, the two outlet side channels being identical and lying along a common longitudinal axis making an acute angle with the parallel flat surfaces. A portion of the skirt is spaced apart from the nozzle to allow hot metal to flow in the space between the nozzle and the skirt.
