摘要： An apparatus for positioning and supporting a shroud tube in a metal teeming operation includes a boom assembly having one end pivotally mounted on a rigid structure for movement about a vertical axis and is articulated intermediate its ends to permit universal movement of its other end in a horizontal plane, and an elongated shroud tube support arm is mounted intermediate its ends on the universally movable end of the boom assembly for movement therewith, for limited pivotal movement about a horizontal axis, and for limited rotational movement about its longitudinal axis. A bifurcated yoke at one end of the support arm engages and supports a shroud tube, and power drive is provided at the other end of the support arm for rotating the support arm about its longitudinal axis. The power drive is operably associated with the boom shroud tube support arm for pivoting the support arm about said horizontal axis, and controls are provided for controlling operation of the power drive to rotate the support arm about the horizontal axis to raise and lower a shroud tube supported on the yoke with the controls being manually operable to selectively raise and lower the shroud tube for positioning relative to the bottom opening in a teeming vessel.
