Abstract
Exemplary embodiments of the invention relate to a flow control apparatus for control of molten metal flow through a trough. The apparatus includes a flow control element (e.g. a movable dam or flow restrictor) movable between an operating position and an inactive position. A guide element provides an elongated track having a first part extending generally parallel to the longitudinal axis of the flow control element. One or more track followers are retained by the guide element and are movable along the track. An elongated arm is attached at one end to the flow control element and to the track follower at an opposite end. An actuator operably connects to the track follower to move the track follower along the track. The track causes the flow control element to move away from the operating position with a straight (non-pivoting) motion, but preferably causes the flow control element to pivot as it approaches the inactive position. The flow control apparatus may be combined with a connector unit for connecting sections of a metal-conveying trough or the like, or may be used directly with such trough or trough sections.
