Abstract

Flow of molten steel from a tundish to a continuous casting mould is controlled by a sliding gate valve (10). The gate valve comprises a stationary refractory member (14) having a metal pouring orifice (18) and a slidable refractory member (37) also having a metal pouring orifice (42) and movable between an open condition in which its orifice (42) is aligned with the orifice (18) of the stationary member, and a closed condition in which the two orifices are out of alignment. Freezing of molten steel at the sliding gate valve when it is closed is prevented by imparting an incremental stepping motion to the slidable member (37) in its closed condition.
