A device for producing metallic bodies by spray coating with an atomized molten metal. The device has a housing at least partially enclosing a crucible, an atomizing device and a material discharge unit, and has through-openings for the workpiece holding device and for the workpiece, which through-openings are provided with seals. In order to ensure a reliable closure of the through-opening for the workpiece holder and workpiece in a simple construction, the rings (23) are supported so as to be rotatable in the through-openings (16, 17) of the housing (11) via bearings (24), at least two pierced disks (21, 22) are provided at each ring (23) and are arranged so as to be parallel and at a distance from one another, and a suction device (30) is connected with a space (33) between the pierced disks (21, 22) for producing a vacuum.

A mold for horizontal continuous casting of steel to form large-format slab cross sections, particularly flat products, includes a water-cooled metal casing forming the mold cavity for a slab and a brake ring for the melt feed which is supported at the mold on the pour-in side and connects the mold with a melt supply vessel (distributor) via a connecting casting tube. In order to provide an inexpensive and particularly stable mold, the mold is closed on the pour-in side by a metal plate along a part of the free cross-sectional area of the mold cavity. The plate has one or more openings for receiving a break ring. An end plate which overlaps the metal plate is arranged in front of the metal plate in surface contact with the metal plate. The end plate is provided with openings which coincide with the openings in the metal plate with respect to position and number. Ducts for guiding cooling water are incorporated in the end plate.

Mold for horizontal continuous casting

A process and apparatus for forming axially symmetrical bodies from molten metal droplets, where the droplets solidify to form the body on a rotating base, with the base moved in an extraction direction away from a spray plane of the metal droplets. The base is moved, the movement of the base and/or the quantitative flow of the metal droplets is controlled by a controller that communicates with a transmitter-receiver, preferably optical, that determines the position of the spray plane.
