Abstract: A method of controlling the movement of particles entrained in a liquid metal flowing along a confined flow path having a substantially horizontal base characterized by the steps of:(1) disposing a first planar device within the flow path to cause the shedding of vortices downstream of the device so that particles having a predetermined range of terminal velocities are trapped within the vortices and agglomerated into clusters of particles.(2) causing the agglomerated particles to be sedimented either upwardly or downwardly and(3) establishing a flow pattern downstream of the first device in which the local Reynolds number decays to a value sufficiently lower than 10.sup.3 to result in essentially laminar flow of the metal so as to minimize re-entrainment and subsequent break up of the agglomerated particles.

Abstract: A tundish and associated assembly are employed for the continuous casting of molten steel containing lead. Undissolved lead can accumulate at the bottom of the tundish, work its way through the refractory material lining the tundish interior bottom and weep through the metal tundish shell bottom into a casting mold located below the tundish, which is undesirable. Expedients are provided to minimize such lead weeping.

Abstract: A ladle stream breaker is disclosed, for use in a tundish comprising a pouring zone where a stream of molten metal is poured from a casting ladle through a pouring tube, and a flotation zone downward the pouring zone, where the molten metal free from its inclusions flows out through a vertical outlet tube into a continuous casting mold. The stream breaker consists of a closed box made from a refractory material, which box has a top wall provided with an opening sized to receive the lower end of the pouring tube, and a number of lateral walls each provided with a plurality of openings sized to allow the molten metal injected into the box to escape from this box in the form of a plurality of sub-streams of low energy. The lateral walls of the closed box and their openings are arranged in such a manner that every sub-stream flowing out of its associated opening impinges a wall of the tundish and flows in a direction substantially perpendicular to this tundish wall. This ladle stream breaker is particularly interesting in that it efficiently dissipates the kinetic energy of the stream of molten metal poured into the tundish and reduces the depth of penetration of this stream inside the tundish, thereby preventing any slag being formed in the pouring zone from being entrained downstream.

Abstract: A cast dam, for use in a tundish, is described. The dam is positioned between the tundish walls in the lower part and protrudes from the tundish floor. It has an L-shape. The dam has ducts connected to at least one pipe for conveying a supply of gas to the tundish. The ducts extend from the pipe to at least one dam surface which becomes exposed to molten metal during use of the tundish. A weir is also provided in the tundish.

Abstract: A method and apparatus for continuous steel casting in which a tubular copper ingot mould is fed with molten steel through an intermediate, so-called ''''tundish'''' pool filled in turn by means of a steelwork ladle. The molten steel, during its passage from the intermediate pool to the ingot mould, is isolated from the surrounding atmosphere by means of a dipper pipe made of sintered vitreous silica. the lubrication between the copper walls of said ingot mould and the steel undergoing a solidification therein is provided by a synthetic slag excluding any organic oil, the slag, which covers the steel surface in the ingot mould being selected from the group of substances having such viscosity and wetting capacity with respect to copper and steel that they can on the one hand penetrate by capillarity action between the copper of the ingot mould and the steel being solidified therein, and on the other hand be carried along in the form of an extremely thin layer between said copper and steel. An additive selected from the group comprising tellurium, selenium, a mixture of these two elements and a chemical combination of one of these two elements is added either into the steelwork ladle, during the filling thereof from a steelwork furnace and before the steel therein is poured into the intermediate pool, or into the intermediate pool, the addition taking place progressively and continuously throughout the casting operation.

Abstract: A diffusion component for impregnating molten steel with a gas includes a barrier having a first side and a second side, a through-hole formed within the barrier, the through-hole connecting the first side to the second side, and a porous element arranged within the through-hole such that the flow of molten steel passes over the porous element. At least one flow disrupter is arranged relative to the porous element and configured to promote non-laminar flow of molten steel passing through the through-hole.
