<p>An improved impact pad (10) for a tundish vessel (70) for use in the iron and steel industry includes a plurality of channels (18) which direct the flow of molten iron or steel toward the tundish drains (84,86), and ramps (22,24) which elevate the flow in the directions of the drains. The ramps cause the molten iron and steel to follow a trajectory path after leaving the impact pad (10), first rising and then falling toward the drains. The trajectory path increases the residence time of the molten iron or steel in the tundish (70), allowing more time for impurities to float to the top of the vessel. The trajectory path also helps propel the impurities partially toward the top of the tundish vessel. <IMAGE></p> |
