  • Process and device for producing thin metal bars
    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.
