Abstract
In a device for controlling a flow of metal from a casting vessel into a casting mould, the inflow of metal is to be controlled by means of a stopper, which may be lifted and lowered according to a preset program and/or by means of a bath-level measuring device. In order to prevent any manual operation of a control lever for the stopper, a lifting rod for the stopper is disposed in a module box together with a vertical guide and a computer-controlled electromechanical drive for the lifting rod. The module box is exchangeably fastened to the casting vessel by clamping elements. Before casting begins, a drive motor for the stopper (13) is to be connected by means of electric plug-and-socket connections to a control cabinet. From the start of casting, the stopper movement is controllable exclusively by means of the electric drive.
