PCT No. PCT/DE94/00656 Sec. 371 Date Jan. 25, 1996 Sec. 102(e) Date Jan. 25, 1996 PCT Filed Jun. 3, 1994 PCT Pub. No. WO94/29048 PCT Pub. Date Dec. 22, 1994An apparatus and a process for making semi-finished products in the form of thin 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.
