Abstract
A pouring pad is provided for use in a tundish during sequence continuous casting. The pouring pad has a plurality of concentric primary ridge portions adjacent to the location of impact of a pouring stream from a ladle with the pad. The primary ridge portions are of a height within a range for creating pockets of recirculation so as to dissipate turbulence without deflection of molten metal from its radially outward flow along the pad. The radial spacing between adjacent primary ridge portions as measured between top inner edge surfaces at corresponding radial points is at least 2.0 times the height of the inner of the adjacent primary ridge portions.
