ABSTRACT:
A sliding gate valve assembly for pouring liquid metal is described in which the frame that mounts the sliding plate is attached directly to oppositely spaced motor apparatus of particular design. Thus, in addition to imparting motion to the slide frame, the motor apparatus also serve to slidably mount the frame thereby eliminating the need for a housing enclosure about the slide frame. According to one aspect of the invention, the frame is movable longitudinally by motor apparatus on two opposed sides of the frame. According to another aspect of the invention, the frame is movable both longitudinally and transversely by pairs of motor apparatus rectangularly disposed about the four sides of the frame. Motor apparatus that is mechanically, electrically or fluid operated can be employed.
