Abstract
A refractory block configured to surround an outlet modifies, within a refractory vessel, the flow of molten metal passing through the outlet. The block takes the form of a base through which a main orifice passes, and a wall extending upwards around the periphery of the base. Structural features that may be included in the block include a circumferential lip around the exterior of the wall, an interior volume in which the radius decreases downwardly towards the main orifice in a plurality of steps, and flow openings in the wall that are configured to induce swirling in the flow pattern in the interior volume of the block.
