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.

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.
