Abstract
An operating mechanism for slidable gates which are used to control flow of liquid from a bottom-pour vessel, and a flow-controlling method. The mechanism is particularly useful for controlling teeming of liquid steel from a tundish into a continuous-casting mold. Most slidable gates either fully open or fully close the outlet of a vessel. The present invention enables the outlet to be partially open, whereby the stream discharging therefrom can be throttled. The mechanism includes a main drive means for pushing gates from a ready position to a slow-motion region under the vessel outlet. The slow-motion region of an orifice gate extends at least from a position in which the vessel outlet is partially open to a position in which it is fully open. An opposed auxiliary drive serves to retard movement of a gate as soon as it reaches the slow-motion region. Thereafter, the main drive pushes an orifice gate slowly and under close control to any desired teeming position within the slow-motion region. The mechanism also includes an improved arrangement for conducting gases to the nozzle at the vessel outlet to prevent skulls from forming, and an improved means for attaching a pouring tube to its holder.
