ABSTRACT:
The slide-valve throttle of the invention is intended to continuously regulate the output of high-temperature molten products from metallurgical vessels, notably from the bottom of casting ladles of the type currently used in foundry, and also for occluding the tap-hole thereof. This throttle comprises essentially an assembly of two slide plates adapted to move towards and away from each other and towards and away from the tap-hole axis, and arranged for uncovering or occluding the tap-hole while preserving for the casting passage formed through the nozzle and the slide plates at least two orthogonal planes of symmetry.
