摘要： 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.

摘要： A pour tube for casting molten metal is adapted to reduce turbulence and mold disturbances, thereby producing a more stable, uniform outflow. The pour tube has a central longitudinal axis and includes a bore in communication with a port distributor having a greater radius with respect to the longitudinal axis than does the bore. Exit ports provide fluid communication between the port distributor and the exterior of the device. Each of a pair of larger exit ports has a larger cross-sectional area than does either of a pair of smaller exit ports.

摘要翻译： 用于铸造熔融金属的浇注管适用于减少湍流和模具干扰，从而产生更稳定，均匀的流出。 倾倒管具有中心纵向轴线，并且包括与端口分配器连通的孔，其相对于纵向轴线具有比孔更大的半径。 出口端口在端口分配器和设备的外部之间提供流体连通。 一对较大的出口中的每一个具有比一对较小出口端口更大的横截面面积。
