  • Patent number: 6153028
    Abstract: A device and a process for producing thin steel metal bars in which an elongated metal product is brought into contact with a molten metal causing the latter to crystallize. Different materials are used for the elongated metal product and the molten metal, whereby one of the materials is a stainless steel. A temperature of the elongated metal product, a temperature of the molten metal and a dwelling time of the elongated metal product in the molten metal are set in such a way that the molten metal crystallizes on the elongated metal product so as to form a layer having a thickness of 2% to 20% of a thickness of the elongated metal product.

  • Patent number: 5881441
    Abstract: An apparatus and a process for making semi-finished products in the form of ti metal bars having a width-gauge ratio of over 60 and a maximum sheet metal gauge tolerance of 2%. A metal profile is fed continuously and upwardly through a pool of melt material having the same composition as the metal profile so as to form a coated metal profile. The metal profile is fed at a rate which would result in a coated metal profile having a thickness of at least three times that of the uncoated metal profile. The coated metal profile is subjected to a smoothing pass between a pair of smoothing rolls when the mean temperature in the crystallized layer of the coated metal profile meets a given condition. The smoothing rolls are adjustably disposed inside a housing at a distance of 0.5 to 5 m from the melt pool surface.

  • Patent number: 5850869
    Abstract: An inversion casting device with a crystallizer which has a slit-shaped passage for guiding a substrate strip, this passage being arranged in the base and provided with a seal, and which communicates with a melt feed. A collecting tank is provided which passes horizontally about the crystallizer vessel so that the collecting tank communicates with nozzles (23) arranged in the region of the passage. The nozzle orifices are so arranged that the melt flowing out strikes the substrate strip at a flat angle of inclination .alpha. in the strip take-off direction.
