Juxtaposed nozzle openings apply the same or different melts to the surface of a moving cooler surface for producing thin metal strips or foils with a considerable width. The nozzle openings can be staggered in the direction of movement of the cooler surface and apply different materials to produce a metal strip with juxtaposed and sharply defined regions with different characteristics. Amorphous or mixed amorphous/crystalline, or solely crystalline material structures can also be produced. Alternatively, different cooling capacities on different cooler surface areas and different structuring of different cooler surface areas permit the melt to solidify on the cooler surface such that the strips or foils obtained have adjacent regions with different metallic and/or geometrical structures. By geometrical configuration of the cooler surface, foils with a structured surface or with shape-limited individual regions can be used for mass production of small parts from sheet or strip material.

Method for producing strip-like or foil-like products

A method of casting metallic strands in a closed pouring or teeming system wherein the metal is cast through a refractory distributor vessel-pouring structure, such as a pouring spout, into an open-ended mold connected in flow communication with the pouring structure. To improve the quality of the strand and to increase the production capacity or output of such installations at the region of a connection plane of the distributor vessel-pouring structure and the open-ended mold the metallic melt is maintained away from the wall of the mold inlet opening by means of a constricting or bundling electromagnetic field.

A method of influencing the distribution of different constituents in an electrically conductive liquid, especially a molten metal, wherein an electrical current is conducted through the electrically conductive liquid and at the same time there is formed a magnetic field approximately perpendicular to the direction of flow of the electric current, in order to reduce or increase the effect of the differences in the density of the constituents.

An apparatus for continuous horizontal casting has a vessel for holding the molten metal to be cast. The vessel has an opening in its side which is arranged so that a stream of molten metal issuing therefrom enters a horizontal path. The stream is maintained in a molten state in the upstream end portion of the path and is cooled in an adjacent downstream portion of the path. A mechanism is provided for continuously drawing the strand formed from the stream of molten metal along the path. During the initial stages of solidification, the strand consists of a thin shell of solidified metal surrounding a molten core. The strand tends to sag here and an arrangement is provided for counteracting the weight of the strand. This arrangement includes a connected pair of electrical contacts one of which is immersed in the body of molten metal and the other of which contacts the strand. The arrangement further includes magnets which generate a horizontal magnetic field extending normal to the axis of the strand. The interaction of the magnetic field and the electrical current along the strand causes an upwardly directed force to be exerted on the strand. Another arrangement is provided for counteracting the metallostatic pressure due to the body of molten metal in the vessel. This arrangement includes coils which surround the path and are arranged to generate an alternating magnetic field around the strand.
